CNC maintenance technology (computer numerical control) is not only the premise to ensure normal operation, but also plays a huge role in promoting the development and improvement of CNC technology, so it has become a specialized subject at present.
Any CNC machines are process control equipment, which requires it to work accurately at every moment of real-time control. Failure and failure of any part will cause the machine to stop, resulting in a production stoppage and machine breakdown.
Therefore, it is very necessary to do the device preventive maintenance with complex principles and precise structures such as the numerical control system. Especially for imported CNC machine tools, most of which cost hundreds of thousands to tens of millions of dollars. In many industries, this equipment is in key jobs.
The following tasks have to be done every day, assuming regular usage hours:

On-site maintenance is to diagnose the failure of the CNC machine tool (mainly the CNC part), find the fault location, and replace it with the corresponding normal spare parts, so that the machine tool can resume regular operation.
The key to this process is the diagnosis, that is, to detect the system or peripheral circuits, determine whether there is a fault, and point out the exact location of the fault for fault location. From the positioning of the whole machine to the patch panel, in some cases, even to the components. This is the main part of the whole maintenance work.
Usually, when the data is relatively complete, the fault can be judged through data analysis, or the interface signal method can be used to judge the parts that may fail according to the fault phenomenon, and then check the parts one by one according to the specific characteristics of the fault and this part, and make a preliminary judgment.
In practical applications, it may be possible to use one method to find and eliminate faults, and sometimes multiple methods are required. The degree of mastery of various methods of judging fault points mainly depends on the depth of mastery of the principles and structures of faulty equipment.
When the numerical control system fails, the fault signal and corresponding information are generally given on the display screen or operation panel. Usually, the operation manual or adjustment manual of the system has a detailed alarm number, alarm content, and processing method.
Because the alarm settings of the system are single, complete, strict, and clear, maintenance personnel can handle them by themselves according to the information and processing methods given after each alarm.
According to the electrical characteristics of the machine tool, the machine tool manufacturer applies PLC programs to display some faults or operation information that can reflect the electrical control of the machine tool interface with specific signs, and give them through the display, and can see more detailed alarm descriptions through specific keys. This type of alarm can be handled according to the troubleshooting manual provided by the machine tool factory, or the operation panel or programmer can be used to find out the corresponding signal state according to the circuit diagram and PLC program, and find the fault point for processing according to the logical relationship.
Troubleshooting with no alarm or no alarm When the PLC of the system cannot be run, the system has stopped or the system does not alarm but works abnormally, it is necessary to analyze and make a decision based on the system status information before and after the failure and using the theoretical basis that has been mastered. correct judgment. This fault diagnosis and troubleshooting method are described below.
1. Visual inspection
Visually inspect the faulty board, carefully check whether there is a blown fuse, charred components, smoking, or cracking and whether there is a foreign body open circuit. In this way, it can be judged whether there are overcurrent, overvoltage, short circuits, and other problems in the board.
2. Touch
Touch and shake the components with your hands, especially the resistance, and capacitance, whether the semiconductor device has a loose feeling, so as to detect some problems of soldering.
3. Power-ups
First, use a multimeter to check whether there is an open circuit between various power supplies.
If there is no, you can connect to the corresponding power supply. Visually check whether there is smoke, ignition, etc., and touch the components for abnormal heat.
Failure, and narrow the scope of maintenance.
For example: when troubleshooting a factory in Harbin, the CNC system and PLC of the machine tool are running normally, but the hydraulic system of the machine tool cannot be started. Use the programmer to check that the PLC program is running normally and that the required signal states meet the startup conditions.
During further inspection, it was found that the PLC signal status was inconsistent with the markings on the drawings and equipment. The machine stopped and pulled out the circuit board for inspection. It was found that the address of the two output boards of the PLC was wrong, and the positions of the other two were wrong. After the exchange, the machine tool ran normally.
For the SIMATIC S5 programmable controller used by the machine tool with this failure, as long as the address is correct, no matter how the position of the circuit board is arranged, the system can run normally. Still, the corresponding executive components and signal sources must be correctly corresponding.
Corresponding errors will cause malfunctions and even destroy the machine tool. In addition, according to the failure phenomenon provided by the user, combined with their own on-site observation, and using the working principle of the system, a correct judgment can be made quickly.
4. System parameter check method
Nowadays, the self-diagnosis function of the operating system of CNC machine tools is getting stronger and stronger, and most of the faults of CNC machine tools can be diagnosed. When the CNC machine tool fails, sometimes the alarm information is displayed on the display, and sometimes there are alarm devices on the CNC device, the PLC device, and the drive device, such as the alarm light will flash, buzzer, and so on.
At this time, first, check the maintenance manual and check the corresponding parameter settings. The loss and incorrect setting of system parameters will cause the change or failure of the machine tool performance.
For example, in the automatic machining of the FANUC system, the machine tool rest stops moving and the screen displays 500 and 501 alarms. Check the parameter manually to find out that the corresponding parameters are stored stroke limit positive and negative limits. At this time, the machine tool can be changed to manual shaking. When the tool holder reaches the correct stroke range and corrects the parameters, the alarm can be removed.
5. Reset machine method
In the process of processing, due to the system alarm caused by the instantaneous fault, the fault can be cleared by hardware reset or turning on and off the system power in turn. The system must be initialized and cleared. Before clearing, you should pay attention to copying and recording important data. If the fault cannot be eliminated after initialization, perform hardware diagnosis.
6. Measurement diagnosis method
Measurement is the basic method for diagnosing equipment failures. We can use instruments such as multimeters, oscilloscopes, and logic testers to measure electronic circuits.
For example, when determining the phase sequence of the three-phase power supply of the numerical control system, the phase sequence table can be used for measurement, that is, the three-phase power line is connected to the phase sequence table. When the phase sequence is correct, the phase sequence table rotates clockwise, and vice versa. It can also be measured with a two-channel oscilloscope. If the phase sequence is correct, the waveforms of each two phase are 120° out of phase.
According to the system circuit diagram and machine tool circuit diagram, the voltage, power supply, pulse signal, etc. of the faulty part are measured to determine the fault. For example, the input voltage of the power supply exceeds the limit, causing the power supply monitoring to use a voltmeter to measure the network voltage or to use a voltage tester to monitor in real-time to eliminate other reasons.
If the position control loop fails, the oscilloscope can be used to check the signal state of the measurement loop, or the oscilloscope can be used to observe whether the signal output is phase-missing and whether there is interference.
For example, when a factory in Shanghai is troubleshooting, the system alarms, and the hardware of the position loop is faulty.
The oscilloscope is used to check and find that there is an interference signal. We use the method of connecting capacitors in the circuit to filter them out to make the system work normally.
When it comes to choosing a CNC machine (computer numerical control ), there are a few things you'll need to take into account in order to make sure you're getting the best possible option for your needs. In this blog post, we'll run through some of the key considerations you should keep in mind when making your decision. By the end, you should have a better understanding of what factors will influence your choice of CNC machine.
How to buy the right machine tool at the most reasonable price to consider the most critical factors? Here is a very useful checklist. Let's get started!
The expertise and proficiency of the machine operators will play a key role. You need to consider what your factory's current CNC machine setup looks like and how much experience your engineers and operators have with CNC machines.
If you already have existing machines, you should assess whether they are still fit for the purpose for which they were made, see where your current gaps lie, assess the life of your machines, and assess the cost-effectiveness of replacing your existing machines with newer, higher-performing machines.
In general, more automated smart machines require less human intervention than simple machine tools with limited functionality.
One of the biggest challenges of CNC machining is the complexity and precision of the parts to be produced.
The precision level of CNC machine tools determines the precision of the parts produced. CNC machine tools can be divided into simple type, full-function type, and precision type according to their machining accuracy. Three indicators to confirm the accuracy. The motion resolution of simple CNC machine tools is 0.01mm, while the precision of precision CNC machine tools is below 0.001mm.
Parts in the automotive, defense, aerospace or medical industries may require advanced CNC machine tools with a wide selection of spindles capable of manipulating, cutting, drilling, and forming parts with multi-axis control. Examples of these machines include 3 to 5-axis machining centers and 2 to 8-axis turning centers. They allow for one, two, or even multi-spindle (mass production) designs.
From standard jobs to highly complex jobs or mass production of complex parts, you can consider a horizontal or vertical CNC lathe with 2 to 5 axes or a CNC milling machine with 3 to 5 axes.
Yangsen has a range of horizontal machining centers to choose from:
The YSH series with a linear guide system is suitable for various applications and production needs. Available with 2 to 5 axes.
If the part is complex and needs to be done in one setup, a multi-axis turning center is a right choice.
Vertical lathes like Yangsen's YSL series are most effective for machining parts with a diameter much larger than the part's length. E.g., Gears, drums, discs, pump casings, engine casings, and rings, etc.
For the production of the fast turnaround of various parts and required machine settings in "High Mix – Small Batch" mode, Yangsen's new 5-axis machining center YS650-5AX offers an incredible solution with its ø650 mm 2-axis Table, 4+1 to full 5 axes and 4 optional spindles (option).
For the toughest materials such as titanium, Inconel, or heat-resistant stainless steel, the YS650-5AX ensures maximum stability and efficiency during simultaneous 5-axis cutting.
1. The high-speed cutting machine is used to complete a medium amount of milling, and then reduce the amount of grinding after milling to a minimum.
2. The CNC milling and machining center is processing equipment used to complete workpieces with a large amount of milling.
3. CNC engraving and milling machine is a processing equipment used to complete a small amount of milling or soft metal.
CNC machines are capable of machining almost most materials, including aluminum, copper, die or hardened steel, titanium, and Inconel.
When choosing a reliable CNC machine tool, you must first clarify your own processing requirements. The specifications and shapes of different parts vary greatly. Generally, the shape of the parts can be divided into plate type, box diamond type, flange shaft type, and special-shaped type. etc. In general, the main processing objects should be selected according to production requirements.
CNC machine tools are divided into roughing and finishing. After determining the parts to be processed, the process of the parts should be planned. When selecting CNC machine tools, their process adaptability should be exerted, and the maximum comprehensive processing ability of CNC machine tools should be exerted to ensure that the entire production process is complete. The process uses the least number of CNC machines and machining parts to maximize the variety of production parts.
The type of material being machined will affect the machine design and spindle selection, as well as the level of performance, durability, load bearing, and precision that can be achieved. The physical properties of the material and optimal cutting conditions also affect machine factors such as the required maximum spindle speed, peak spindle motor horsepower, and maximum spindle motor torque.
Next, you need to consider whether you should choose a CNC machine that uses a linear guide (LM) rail system, or a stronger, more rigid box rail design.
You need to consider four main factors here: speed, stiffness, load-carrying capacity, and tool life.
CNC machines built with LM guides tend to be faster but better suited for light-duty applications. On the other hand, machines with box rails are stronger, have less vibration, and are capable of making heavier cuts on large parts. However, these are generally slower than those with LM rails.
When choosing between the two, it's useful to ask yourself the following questions:
What is the material to be cut?
How much vibration damping is required?
What is the required cutting feed rate?
What is the expected and required tool life?
When choosing the right machine tool, you also need to match your choice with choosing the most practical CNC controller. This depends not only on the level of automation but also on the number of axes to be controlled and the manual intervention required in the production process. The semi-closed-loop numerical control system can automatically detect the position and compensate for the error. The fully closed-loop CNC system is the CNC system with the highest precision, but it is difficult to maintain and expensive.
The CNC system can control the processing and operation of CNC machine tools and can be called the core "brain" of CNC machine tools.
The open-loop CNC system is often used for CNC wire-cutting tools with low precision requirements. It does not have a position detection device and is positioned by the drive unit. It has the characteristics of low cost, simple structure, and low operation and maintenance.
In addition to choosing the best and largest screen for your CNC control, you should also consider the following important factors:
Reliability of CNC Control System
Effectiveness of Control
Software stability
User-friendliness - can you find the operators for these controls?
All CNC control systems of our CNC machines are the top 2 brands in the world. Fanuc and Siemens.
To determine this, you need to consider both fixed and variable costs:
Fixed costs: initial capital investment, machine depreciation, loan interest (if any)
Variable costs: material costs, labor costs, tool costs, tool change, maintenance and repair costs, spare parts costs
Note that choosing a cheaper machine does not necessarily guarantee you better productivity or plant profitability in the long run.
Weight is an important factor to consider when selecting a CNC machine, as it affects the overall stability of the machine and its ability to handle heavier loads.
A lighter machine will be more susceptible to vibration which can lead to inaccurate cuts and poor results. Additionally, a heavier machine may require stronger motors or other components in order to handle larger workpieces or for more accurate and precise cutting. Ultimately, selecting a CNC machine that has the right weight is important to ensure optimal performance and quality results from your machining operations.
We choose the best-built iron cast from the machine body, to guarantee enough stability and rigidity.
Last but not least, you need to consider how much space you have in your shop for a new machine.
Of course, this varies by industry and may include factors such as:
Make the most of available floor space
Minimize worker movement between machines
Material flow and space from point to point
Improve productivity
Chip processing
Safety conditions for workers
Room for future expansion
Available power points, and power requirements.

A CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer surfaces, and cylindrical and conical threads, etc., and can perform grooving, drilling, reaming, and reaming. Holes and borings, etc.
The CNC machine tool automatically processes the parts to be processed according to the pre-programmed processing program. We write the machining process route, process parameters, tool motion trajectory, displacement, cutting parameters, and auxiliary functions of the part into a machining program list according to the instruction code and program format specified by the CNC machine tool, and then record the content of the program list.
On the control medium, it is then input into the numerical control device of the numerical control machine tool, thereby directing the machine tool to process the parts.
Traditional machining is done by manual operation of ordinary machine tools. During machining, mechanical tools are shaken by hand to cut metal, and calipers and other tools are used to measure the accuracy of products.
Modern industries have already used computer numerically controlled machine tools for the operation, and CNC machine tools can automatically process any product and component directly according to the program pre-programmed by technicians. This is what we call CNC machining.
CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process the program specified by the control code or other symbolic instructions, and decode it, so as to make the machine tool move and process the parts.
Compared with ordinary machine tools, CNC machine tools have the following characteristics:
1. High processing precision and stable processing quality;
2. Multi-coordinate linkage can be carried out, and parts with complex shapes can be processed;
3. When the machining parts are changed, generally only the NC program needs to be changed, which can save production preparation time;
4. The machine tool itself has high precision and rigidity and can choose favorable processing amount, and the productivity is high (generally 3~5 times that of ordinary machine tools);
5. The machine tool has a high degree of automation, which can reduce labor intensity;
6. Higher quality requirements for operators and higher technical requirements for maintenance personnel.
The CNC lathe is composed of a CNC device, bed, spindle box, tool post feed system, tailstock, hydraulic system, cooling system, lubrication system, chip conveyor, and other parts.
CNC lathes are divided into two types: vertical CNC lathes and horizontal CNC lathes.
Vertical CNC lathes are used for turning disc parts with large turning diameters.
Horizontal CNC lathes are used for turning long or small disc parts in axial size.
Horizontal CNC lathes can be further divided into economical CNC lathes, ordinary CNC lathes, and turning centers according to their functions.
Economical CNC lathe: a simple CNC lathe formed by transforming the turning feed system of an ordinary lathe by using a stepping motor and a single-chip microcomputer. The cost is low, the degree of automation and functions are relatively poor, and the turning accuracy is not high, and it is suitable for turning rotary parts with low requirements.
Ordinary CNC lathe: It is specially designed in structure according to the requirements of turning to process, and is equipped with a general CNC system. The CNC system has strong functions, a high degree of automation, and high machining accuracy, and is suitable for turning general rotary parts. This CNC lathe can control two coordinate axes at the same time, namely the x-axis and the z-axis.
Turning machining center: On the basis of ordinary CNC lathes, the C axis, and power head are added. More advanced machine tools also have tool magazines that can control three coordinate axes of X, Z, and C. The linkage control axis can be (X, Z), (X, C), or (Z, C). Due to the addition of the C-axis and milling power head, the processing function of this CNC lathe is greatly enhanced.
Hydraulic chuck and hydraulic tailstock
A hydraulic chuck is an important accessory for clamping workpieces during CNC turning. Common hydraulic chucks can be used for general rotary parts; special chucks are required for parts whose clamped parts are not cylindrical; Spring chucks are required when machining parts.
CNC lathes can be equipped with two tool holders:
①Special tool holder: It is developed by the lathe manufacturer itself, and the tool holder used is also dedicated. The advantage of this tool holder is that it is cheap to manufacture, but it lacks versatility.
②Universal tool holder: The tool holder is produced according to certain general standards (such as VDI, German Association of Engineers), CNC lathe manufacturers can choose and configure it according to the functional requirements of CNC lathes.
Milling power head
After installing the milling power head on the CNC lathe tool holder, the processing capacity of the CNC lathe can be greatly expanded. Such as axial drilling and milling of axial grooves with a milling power head.
CNC machines are available with programs that include numbers and letters, which can help to navigate parts around various distances. A machine programming language may be implemented on Gcode or a specialized language developed in manufacturing. Basic mills consist of three wheel-based systems (XY - Z) however newer mills may contain three more wheels in addition.
When turning parts on a CNC lathe or turning machining center, the position of the tool on the tool holder should be reasonably and scientifically arranged according to the tool holder structure of the lathe and the number of tools that can be installed, and attention should be paid to avoid the tool being stationary and working. Interference phenomenon with machine tools, tools and workpieces, and tools.
The host is the main body of the CNC machine tool, including the machine body, column, spindle, feed mechanism, and other mechanical components. It is a mechanical part used to complete various cutting operations.
The numerical control device is the core of the numerical control machine tool, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and corresponding software, which is used to input the digital part program and complete the storage of input information and data storage. Transform, interpolate, and implement various control functions.
The drive device is the drive component of the CNC machine tool actuator, including the spindle drive unit, the feed unit, the spindle motor, and the feed motor. He realizes the spindle and feed drive through the electric or electro-hydraulic servo system under the control of the numerical control device. When several feeds are linked, the processing of positioning, straight line, plane curve, and space curve can be completed.
Auxiliary devices, some necessary supporting components of the index control machine tool, to ensure the operation of the CNC machine tool, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal devices, exchange tables, CNC turntables, and CNC indexing heads, as well as tools and monitoring and testing devices.
The lifting and positioning of the machine tool should use the special lifting tools provided by the manufacturer, and other methods are not allowed. No special hoisting tools are required, and steel wire ropes should be used to hoist and position according to the specified parts of the manual.
The machine tool should be installed on a solid foundation, and the location should be away from the vibration source; avoid sunlight and heat radiation; place it in a dry place to avoid the influence of moisture and airflow. If there is a vibration source near the machine tool, an anti-vibration trench must be set around the foundation.
The machine tool is placed on the foundation, it should be leveled in a free state, and then the anchor bolts are evenly locked. For ordinary machine tools, the level reading does not exceed 0.04/1000mm, and for high-precision machine tools, the level does not exceed 0.02/1000mm.
When measuring the installation accuracy, it should be carried out at a constant temperature, and the measuring tool should be used after a period of constant temperature. When installing the machine tool, try to avoid installation methods that force the machine tool to deform. When the machine tool is installed, some parts of the machine tool should not be removed casually. The removal of the parts may lead to the redistribution of the internal stress of the machine tool, thus affecting the accuracy of the machine tool.
After the geometric accuracy of the machine tool has passed the inspection, the whole machine needs to be cleaned. Use cotton or silk cloth soaked with the cleaning agent, not cotton or gauze. Clean off the anti-rust oil or anti-rust paint applied to protect the guide rail surface and the machined surface when the machine tool leaves the factory. Clean the dust from the outer surface of the machine tool. Coat each sliding surface and working surface with lubricating oil specified by the machine tool.
Carefully check whether all parts of the machine tool are oiled as required and whether enough coolant is added to the cooling box. Whether the oil of the hydraulic station of the machine tool and the automatic lubricating device has reached the specified position of the oil level indicator.
Check whether the switches and components in the electrical control box are normal and whether the integrated circuit boards are in place.
Turn on the power and start the centralized lubrication installation, so that the lubricating parts and the lubricating oil circuit are filled with lubricating oil. Do all the preparations before the action of each part of the machine tool.
Since CNC lathe processing is a high-precision work, its processing procedures are concentrated and the number of parts clamping is small, which puts forward higher requirements for the CNC tools used. The following Dongguan Tongli Metal Products Co., Ltd. is here for you. introduce.
When choosing tools for CNC machine tools, the following aspects should be considered:
① The type, specification, and precision grade of CNC tools should be able to meet the processing requirements of CNC lathes.
②High precision. In order to meet the requirements of high precision and automatic tool change of CNC lathe processing, the tool must have high precision.
③High reliability. To ensure that accidental tool damage and potential defects do not occur in CNC machining and affect the smooth progress of machining, it is required that the tool and the accessories combined with it must have good reliability and strong adaptability. Precision metal processing
④High durability. The tools processed by CNC lathes, whether in roughing or finishing, should have higher durability than those used in ordinary machine tools, so as to minimize the number of replacement or grinding tools and tool settings, thereby improving the processing of CNC machine tools. Efficiency and guaranteed processing quality.
⑤ Good chip breaking and chip evacuation performance. In CNC lathe processing, chip breaking and chip removal cannot be handled manually like ordinary machine tools.
The chips are easy to wrap around the tool and the workpiece, which will damage the tool and scratch the machined surface of the workpiece, and even cause injuries and equipment accidents. , affecting the processing quality and the safe operation of the machine tool, so the tool is required to have good chip breaking and chip removal performance.
In hardware processing, all rotary parts that can be clamped on an ordinary lathe can be processed on a CNC lathe. However, CNC lathes have the characteristics of high machining accuracy, linear and circular interpolation, and automatic speed change in the process of hardware processing, and their technological scope is much wider than that of ordinary machine tools.
The CNC lathe has good rigidity, high manufacturing, and tool setting accuracy, and can easily and accurately enter manual compensation and automatic compensation. Therefore, it can process parts with high dimensional accuracy requirements.
In addition, the tool movement of CNC turning is realized by high-precision interpolation movement and servo drive.
In addition, the rigidity of the machine tool is good and the manufacturing precision is high. Therefore, it can process the shape accuracy of the busbar straightness, roundness, cylindricity, etc. Demanding parts. For arcs and other curved profiles, the machined shape is much closer to the geometry required on the drawing than with a copy lathe.
The CNC lathe has a constant line speed cutting function, so the optimal line speed can be used to cut the tapered surface and the end surface, so that the surface roughness value after turning is small and consistent, and the parts with small and uniform surface roughness value can be processed.
The location of the machine tool should be far away from the vibration source, direct sunlight and thermal radiation should be avoided, and the influence of humidity and airflow should be avoided. If there is a vibration source near the machine tool, anti-vibration grooves should be set around the machine tool.
Otherwise, it will directly affect the machining accuracy and stability of the machine tool, which will cause poor contact with the electronic components, failure, and affect the reliability of the machine tool.
Generally, CNC lathes are installed in the machining workshop, not only does the ambient temperature change greatly, and the use conditions are poor, but also there are many mechanical and electrical equipment, resulting in large fluctuations in the power grid. Therefore, the location where the CNC lathe is installed requires strict control of the power supply voltage. Power supply voltage fluctuations must be within the allowable range and remain relatively stable. Otherwise, the normal operation of the CNC system will be affected.
The ambient temperature of the CNC lathe is lower than 30 degrees Celsius, and the relative temperature is less than 80%.
Generally speaking, there is an exhaust fan or a cooling fan inside the CNC electric control box to keep the working temperature of the electronic components, especially the central processing unit, constant or the temperature difference changes very little.
When using the machine tool, the user is not allowed to change the parameters set by the manufacturer in the control system at will. The setting of these parameters is directly related to the dynamic characteristics of each component of the machine tool. Only the backlash compensation parameter values can be adjusted according to the actual situation.
The user cannot change the accessories of the machine tool at will, such as using the hydraulic chuck beyond the specification. The manufacturer fully considers the matching of various link parameters when setting accessories. Blind replacement results in a mismatch of parameters in various links, and even cause unexpected accidents.
The pressure of the hydraulic chuck, hydraulic tool rest, hydraulic tailstock, and hydraulic cylinder should be within the allowable stress range, and it is not allowed to increase arbitrarily.
CNC lathe is a high-precision, high-efficiency automatic machine tool. Equipped with a multi-station turret or a power turret, the machine tool has a wide range of processing performance, which can process linear cylinders, oblique cylinders, arcs, and various threads, grooves, worms, and other complex workpieces, with linear interpolation, arc Interpolate various compensation functions, and play a good economic effect in the mass production of complex parts. The maintenance of the CNC lathe with the inclined bed is as follows:
In order to ensure the working accuracy of the CNC lathe with an inclined bed and prolong the service life, it is necessary to carry out reasonable maintenance work on the CNC lathe with an inclined bed for self-use.
In order to use CNC lathes one must be able to successfully complete a specified amount of courses and obtain appropriate certification. CNC turning machining programs usually include multiple class sessions that offer a gradual instruction program split into several sections. Throughout the training, a safety protocol should be respected. Beginning machining classes can be difficult without practical experience, but they can help familiarize the students with the commands in CAD files and CAD programming.
A milling machine mainly refers to a machine tool that uses a milling cutting tool to process various surfaces of workpieces. Usually, the rotary motion of the milling cutting tool is the main motion, and the movement of the workpiece and the milling cutting tool is the feed motion. It can process planes, grooves, various curved surfaces, gears, etc. In addition to milling planes, grooves, gear teeth, threads, and spline shafts, milling machines can also process more complex profiles, with higher efficiency than planers, and are widely used in machinery manufacturing and repair departments.
Moreover, it can also be used to process the surface of the revolving body, the inner hole, and the cutting work. When the milling machine is working, the workpiece is mounted on the table or the accessories such as the indexing head. The rotation of the milling cutter is the main movement, supplemented by the feed movement of the table or the milling head, and the workpiece can obtain the required machining surface.
Due to the multi-blade interrupted cutting, the productivity of the milling machine is high. In simple terms, a milling machine is a machine tool that can mill, drill, and bore a workpiece.
In 1818: the first milling machine was a horizontal milling machine created by American E. Whitney.
In 1862: To mill the spiral groove of the twist drill, American J.R. Brown created the first universal milling machine, which was the prototype of the milling machine for the lifting table.
Around 1884: the gantry milling machine appeared.
In the 1920s: semi-automatic milling machines appeared, and the worktable used stops to complete the automatic conversion of "feed-fast" or "rapid-feed".
After 1950, milling machines developed rapidly in terms of control systems, and the application of digital control greatly improved the automation of milling machines.
Especially after the 1970s, the digital control system and automatic tool change system of the microprocessor were applied to the milling machine, which expanded the machining range of the milling machine and improved the machining accuracy and efficiency.
With the continuous intensification of the mechanization process, CNC programming has been widely used in machine tool operations, which has greatly released the labor force. CNC programming milling machines will gradually replace manual operations. The requirements for employees will also be higher and higher, and of course, the efficiency will be higher and higher.
There are universal, horizontal and vertical, etc., mainly used for processing small and medium-sized parts, the most widely used.
Gantry milling and boring machines, gantry milling planers, and double-column milling machines, all of which are used to process large parts.
The horizontal milling head of the former can move along the column guide rail, and the worktable is fed longitudinally; the end milling head of the latter can move horizontally along the cantilever guide rail, and the cantilever can also adjust the height along the column guide rail. Both are used for machining large parts.
There are two types of rectangular tables and circular tables, which is a medium-sized milling machine between the lifting table milling machine and the gantry milling machine. Its vertical movement is completed by the milling head rising and falling on the column.
A small lift table milling machine for machining instrumentation and other small parts.
Used for mold and tool making, equipped with various accessories such as end milling head, universal angle table, and plug, and can also perform processing such as drilling, boring, and plunging.
such as keyway milling machines, cam milling machines, crankshaft milling machines, roll journal milling machines, and square steel ingot milling machines, etc., are special milling machines manufactured for processing corresponding workpieces.
a small milling machine used for milling small parts such as instruments and meters.
a milling machine with the milling head mounted on the cantilever, the bed is arranged horizontally, the cantilever can generally move vertically along the column guide rail on one side of the bed, and the milling head moves along the cantilever guide rail.
a milling machine with the spindle mounted on the ram.
The machine body is arranged horizontally, and the columns and connecting beams on both sides form the gantry milling machine. The milling head is mounted on the beam and column and can move along its guide rails. Usually, the beam can move vertically along the guide rail of the column, and the worktable can move vertically along the guide rail of the bed for processing large pieces.
a milling machine for milling planes and forming surfaces.
a milling machine that copies the workpiece. Generally used for machining complex shape workpieces.
a milling machine with a lifting table that can move vertically along the guide rail of the bed. Usually, the worktable and the saddle installed on the lifting table can move longitudinally and laterally, respectively.
The rocker arm milling machine can also be called a turret milling machine, a rocker arm milling machine, and a universal milling machine. The turret mills machine of the machine tool is a light general metal cutting machine tool with two functions vertical and horizontal milling. Flat surface, bevels, grooves, and splines for small parts, etc.
The worktable cannot be raised and lowered but can be moved longitudinally and laterally along the guide rail of the bed base, and the milling head or column can be moved vertically.
Such as tool milling machines: are milling machines used for milling tools and molds, with high machining accuracy and complex machining shapes.
Milling machines can be divided into:
copy milling machines,
program-controlled milling machines
CNC milling machines.
To be used for machining planes, steps, grooves, forming surfaces, and cutting workpieces on milling machines.
There are many commonly used types of milling cutters according to their uses:
Used for machining planes on horizontal milling machines. The cutter teeth are distributed on the circumference of the milling cutter and are divided into straight teeth and helical teeth according to the tooth shape. According to the number of teeth, there are two kinds of coarse teeth and fine teeth. The helical-tooth coarse-tooth milling cutter has few teeth, high tooth strength, and large chip space, which is suitable for rough machining; the fine-toothed milling cutter is suitable for finishing.
used for vertical milling machines, face milling machines or gantry milling machines, upper processing plane, there are cutter teeth on the end face and circumference, and there are coarse teeth and fine teeth. Its structure has three types: integral type, insert type, and indexable type.
used for machining grooves and stepped surfaces, etc. The cutter teeth are on the circumference and end face, and cannot be fed in the axial direction during the end milling operation. When the end mill has end teeth that pass through the center, it can be fed axially (usually double-edged end mills are also called "keyway mills" and can be fed axially).
It is used to process various grooves and stepped surfaces, and there are cutter teeth on both sides and on the circumference.
used for milling grooves at a certain angle, there are two types of single-angle and double-angle milling cutters.
It is used for machining deep grooves and cutting workpieces, and there are more teeth on its circumference. In order to reduce friction during milling, there are 15' to 1° secondary declinations on both sides of the cutter teeth. In addition, there are keyway milling cutters, dovetail milling cutters, T-slot milling cutters, and various forming milling cutters.
The cutter teeth are made of cemented carbide or other wear-resistant tool materials and are brazed on the cutter body.
The cutter teeth are fastened on the cutter body by mechanical clamping. The replaceable teeth can be a head of a solid tool material or a head of a welded tool material. The milling cutter with the cutter head mounted on the cutter body is called the internal grinding type; the cutter head is sharpened separately on the fixture is called the external grinding type.
This structure has been widely used in face milling cutters, end milling cutters, and three-side edge milling cutters.
Metal cutting machine tools have implemented the export product quality licensing system, and products that have not obtained the export product quality license are not allowed to be exported. When ordering, the equipment parameters, metric and inch system, power supply, voltage, and frequency, as well as random accessories, the color of the machine tool, etc. must be clearly specified. In view of the wide variety of CNC punch presses and different standards in the sheet metal industry, when customers order molds, they should learn the following information from the manufacturer:
determine which of the long guide or short guide type the mold structure is and whether it is an imported Murata structure or a Trumpf structure or Yangsen Structure;
whether the punching force of this mold is suitable for this machine tool, otherwise, the structure of the mold must be changed or other processing methods must be selected;
if the machine station is a non-rotating station, the double keyway structure must be considered for the guide bush or the lower die;
in order to determine the height of the lower mold of the mold (forming mold);
the material and thickness of the sheet processed by the customer must be determined to determine the material and gap selected for the mold;
the direction of the positioning pin (slot) of the mold (especially the special-shaped mold) should be determined according to the customer's processing requirements. In addition, except for the square edge mold, the guide sleeve or lower mold of the other molds must consider two keyways;
There are many types of molds, and it is necessary to clarify the type of mold ordered by the customer.
1. When loading and unloading the workpiece, the tool must be removed, and the cutting head and hand should not be close to the milling surface.
2. When using a milling machine for tool setting, it must be jogged or hand-cranked, and fast forward is not allowed.
3. When advancing and retracting the tool quickly, pay attention to whether the handle of the milling machine will hit someone.
4. Do not feed too fast, and do not change speed suddenly, and the limit stop of the milling machine should be adjusted well.
5. The Asahi milling machine must be stopped when moving up and down, measuring the workpiece, adjusting the tool, and tightening the speed change.
6. When disassembling and assembling the end mill, the work surface should be padded with wooden boards, the pulling out of the flat mill should be disassembled, and the force should not be excessive.
7. It is strictly forbidden to touch or wipe the rotating parts and knives with cotton yarn.
8. In general, a collet can only clamp one workpiece at a time. Because a collet clamps more than one workpiece at a time, even if the clamp is tight, the force during rough feeding is very large, and the two workpieces are easy to slide between them, causing the workpiece to fly out, the knife is broken, and the injury accident.

Most of the gantry milling machines are made of steel or cast iron. In the long-term use process, due to the friction between the two contact surfaces of different degrees, the surface of the milling machine guide rail will be worn to different degrees, which will seriously affect the machining accuracy and production efficiency of the equipment.
Traditional repair methods usually use metal plate affixing or replacement, but require a lot of precise tolerances manufacturing and manual scraping, repairing requires many processes and a long construction period. The problem of scratches and strains on the gantry milling machine can be solved by using polymer composite materials, among which there should be a mature technology system.
Due to the material's excellent adhesion, compressive strength, and oil and wear resistance, it provides a long-lasting protective layer for components. It only takes a few hours to repair the scratched part of the machine tool and put it into use. Compared with the traditional method, the milling operation is simpler and the cost is lower.
The development of horizontal boring and milling machines has attracted much attention because of its injection of the concept of acceleration. The transmission elements, such as electric spindles, linear motors, and linear guides, which are technical support for high-speed milling operation, have been widely used, pushing the running speed of the machine tool to a new height. The innovative design of the spindle-replaceable horizontal boring-milling machining center solves the disadvantages of the electric spindle and the boring bar mobile telescopic structure. Technological innovation.
The development of floor-type milling and boring machines leads to the trend of modern processing with its new design concept. The structure type with no boring shaft ram type and various milling heads exchanged with the concept of high-speed processing are full of style, which can greatly replace traditional milling processing. the trend of. Various milling head accessories represented by the two-coordinate swing angle milling head have become the main means to achieve high-speed and high-efficiency composite machining. Its process performance is wider, the power is higher, and the rigidity is stronger, which is a major breakthrough in the development of floor milling and boring machines.
The main key component of the horizontal boring and milling machine is the spindle box, which is installed on the side of the column. There are also a few manufacturers who use the double-column thermal symmetry structure, placing the spindle box in the middle of the column. The biggest feature of this structure is rigidity, balance, and good heat dissipation performance, which provides a reliable guarantee for the high-speed operation of the headstock. However, the double-column structure is inconvenient for maintenance, which is the reason why there are not many manufacturers using it today. The movement of the spindle box is mostly driven by the motor-driven ball screw, which is the core transmission device of the spindle drive. As the spindle speed is getting higher and higher and the spindle heats up quickly, many manufacturers have adopted oil mist cooling instead of oil cooling to more effectively control the spindle temperature and ensure its accuracy.
There are two main types of spindle systems, one is the traditional boring bar telescopic structure, which has the characteristics of deep hole boring and high-power cutting; the other is the modern high-speed electric spindle structure, which has high speed, fast running speed, and high efficiency, the advantages of high precision.
There are more and more applications of high-speed motorized spindles on horizontal boring and milling machines. In addition to greatly improving the speed and accuracy of the spindle, it also simplifies the internal structure of the headstock and shortens the manufacturing cycle, especially for high-speed cutting.
Larger than 10000r/min. The disadvantage is that the power is limited, its manufacturing cost is high, especially deep hole machining cannot be performed. The boring bar telescopic structure has limited speed, and the accuracy is not as good as that of the electric spindle structure, but it can carry out deep hole processing, has high power, can perform full-load processing, and has high efficiency, which is unmatched by the electric spindle. Therefore, the two structures coexist with different process performances but provide users with more choices.
A replaceable spindle system has also been developed, which has the function of one machine and two functions. Users can choose to use it according to different processing objects, that is, the electric spindle and the boring bar can be replaced with each other. This structure takes into account the shortcomings of the two structures, and also greatly reduces the cost. It is a great innovation of today's horizontal boring and milling machine. The advantages of the electric spindle lie in high-speed cutting and rapid feed, which greatly improves the precision and efficiency of the machine tool.
The running speed of the horizontal boring and milling machine is getting higher and higher, the fast-moving speed reaches 25-30m/min, and the maximum speed of the boring bar is 6000r/min. The speed of the horizontal machining center is higher, the rapid movement is as high as 50m/min, the acceleration is 5m/s2, the position accuracy is 0.008 ~ 0.01mm, and the repeated positioning accuracy is 0.004 ~ 0.005mm.
Since the floor milling and boring machine mainly process large parts, the milling process has a wide range, especially high-power and powerful cutting is a major processing advantage of the floor milling and boring machine, which is also the traditional process concept of the floor milling and boring machine. The technological development of contemporary floor milling and boring machines is changing the traditional process concept and processing method. The process concept of high-speed machining is replacing the traditional heavy-cutting concept, bringing about changes in processing methods with high speed, high precision, and high efficiency, which also promotes the structural change of the floor-type milling and boring machine and the improvement of the technical level.
Today, the biggest feature of the development of floor-type milling and boring machines is the development of high-speed milling, all of which are ram-type (without boring shaft) structures and equipped with various milling head accessories with different process performances. The advantages of this structure are that the ram has a large cross-section, good rigidity, long stroke, and fast-moving speed, and it is easy to install various functional accessories, mainly high-speed boring, milling head, two-coordinate double swing angle milling head, etc. The performance and processing range have reached the extreme, greatly improving the processing speed and efficiency.
Traditional milling is processed by boring bars, while modern milling is mostly completed by various functional accessories through rams. There is a trend to replace traditional processing. Its advantages are not only the speed and efficiency of milling but also the ability to carry out the processing of polyhedrons and curved surfaces cannot be accomplished by traditional processing methods. Therefore, many manufacturers are competing to develop and produce ram-type (without boring shaft) high-speed machining centers, because of their economic and technical advantages, and can greatly improve the technological level and technological scope of machine tools. At the same time, the machining accuracy and machining efficiency are improved. Of course, various types of high-precision milling head accessories are needed for technical support, and the requirements are also very high.
High-speed milling has brought structural changes to the floor-mounted milling and boring machine. The structure with the headstock in the center is relatively common, and its rigidity is high and suitable for high-speed operation. The ram drive structure adopts a linear guide rail and linear motor drive. This structure is necessary for high-speed cutting. Foreign manufacturers have adopted it on floor-type milling and boring machines. Similar domestic products are rare. guide. High-speed machining also puts forward higher requirements for the environment and safety, which brings about the concept of pleasant mass production. All manufacturers attach great importance to the safety protection and operability of people under the high-speed operation of the machine tool. The fully enclosed structure is implemented, which is both safe and beautiful.
The traditional horizontal boring and milling machine is mainly suitable for the processing of various mechanical parts, especially the mechanical transmission box and various curved surface parts. Due to the improvement of the technical level of various equipment, the requirements for the mechanical structure are becoming more and more simplified, and fewer transmission parts are required, especially the parts used as the transmission box will be less and less, the mechanical transmission is mostly direct drive, and the transmission parts are The precision requirements are very high, which puts forward higher requirements on the technological performance of horizontal boring and milling machines. Therefore, as in the traditional boring-shaft type structure, the processing objects tend to decrease and will be replaced by the boring-shaft-free electric spindle, that is, the high-speed machining center will complete the processing of various parts. The development of horizontal boring and milling machines to high-speed machining centers, on the one hand, is more adaptable to the process, and on the other hand, it also improves the performance level and machining accuracy. Boring and milling, as well as drilling and tapping, equipped with CNC swing angle milling head accessories, and can also process various curved body parts. Equipped with an exchangeable worktable to form a flexible processing unit, which can process parts in batches.
The floor-type milling and boring machine mainly process large and super-large parts of various profiles. At the same time, it can also be equipped with a rotary table, which can perform rotary indexing and radial linear motion, and complete the multi-sequence processing of parts through indexing, which greatly improves the process range. The floor-type milling and boring machine produced by the Italian Pama (Pama) company is specially equipped with a tilting adjustable angle worktable, which further expands the processing range. High-power and high-efficiency cutting is a major processing advantage of floor-type milling and boring machines. The technical requirements of high speed and high precision are increasingly affecting the technical development of floor-type milling and boring machines, which is an important means to improve the technological level of floor-type milling and boring machines. Therefore, floor-type milling and boring machine are changing the single high-power, high-efficiency cutting, and more into the high-speed, high-precision process technology connotation. The ram structure has become the main structure type for high-speed milling and boring. The ram has a large cross-section, high rigidity, and good high-speed running stability. It is easy to install various milling head accessories to achieve high-speed machining.
The development of heavy machine tools will present two major trends.
On the one hand, the development direction is technically based on machining centers or large flexible machining units and large combined compound machining machines. Among them, horizontal boring and milling machines will be gradually replaced by high-speed machining centers and flexible machining units; The combined composite machining center is mainly composed of two or more main machines combined into a composite machining machine tool to adapt to the single-piece and small-batch production of large-scale machining parts. The process is complex, and the auxiliary time and processing cycle are long.
It is difficult for the machine tool to complete all the processing steps, but it can be achieved by two combined machining centers. For example, two CNC gantry boring and milling machines form a composite machining center, and share the bed and guide rails, respectively equipped with a rectangular worktable and a rotary worktable (indexing), which can perform boring and milling processing; a floor-type milling and boring machine and A CNC single-column vertical lathe constitute a large-scale composite machining center, sharing the guide rail of the bed, with a floor platform and a rotary table, which can complete processing such as turning, boring, milling, and drilling, and the rotary table can be indexed.
There are also various combinations such as two large floor milling and boring machines sharing the bed guide rail. In this way, the floor space is saved, the cost is reduced, and the processing efficiency is improved.
Another development trend is to pursue refined manufacturing, improve the technological content of equipment manufacturing, and reflect the safety, environmental protection, and humanized characteristics of machine tools.
To sum up, the technology of contemporary horizontal boring-milling machines and floor-standing boring-milling machines has developed very fast, which is mainly reflected in the update of design concept and the great improvement of machine tool running speed and manufacturing process level.
On the other hand, the structure of machine tools has changed greatly. The application of new technologies is endless. The structure of the horizontal boring and milling machine develops towards the high-speed motorized spindle, and the floor-standing milling and boring machine develop towards the ram-type (without boring shaft) structure. The new trend of technological development in the coming period.
There are two types of machining centers: vertical machining centers and horizontal machining centers.
The main difference between the two is the Z-axis structure. The Z-axis of the horizontal machining center moves horizontally downward, while the Z-axis of the vertical machining center moves vertically downward.
In addition, there are certain differences in their work tables, operation, processing conditions, and prices.
When choosing a machining center, the choice of vertical or horizontal mainly depends on the processing object.
Let's learn together - how to correctly choose vertical and horizontal machining center machine tools.
Machining centers can be divided into vertical machining centers and horizontal machining centers according to the state of the spindle in space.
There are certain differences between these two machining centers:
The main difference between the horizontal machining center and the vertical machining center is the difference in the Z-axis structure.
The Z-axis (spindle axis) of the horizontal machining center moves horizontally downward to complete the processing.
The Z-axis of the vertical machining center moves vertically downward to complete the processing. so the spindle axis of vertical machining centers is in the vertical direction.
The table of the horizontal machining center is only designed to move in the X or Y direction. The table is generally a rotary table with a lattice screw hole table, and it is relatively easy to choose an exchangeable double table.
And generally speaking, horizontal machining centers usually have larger table sizes.
The vertical machining center table is usually a T-slot table with a cross-slide structure. There are two sets of motion mechanisms responsible for the movement in the vertical direction. The X-direction feed table covers the guide rail responsible for the Y-direction feed.
The vertical machining center is easy to clamp, easy to operate, easy to observe the processing situation, and easy to debug the program. Vertical machining centers often use long cylindrical tools called end mills for more precise but shallower cuts on smaller workpieces with a high precision requirement.
The workpieces processed by the horizontal machining center are generally relatively larger, with a higher degree of integration, more difficult to clamp, not easy to monitor the processing process, and relatively difficult to operate and debug.
But under the same table travel of 2 machines, even if it is a large vertical machining center, it is still difficult to compare with a horizontal machining center in terms of processing large workpieces. Large vertical machining centers cannot process parts that are too high.
While large vertical machining centers are relatively easy to be affected by chips when machining concave surfaces, so horizontal machining centers have advantages when machining large workpieces.
The horizontal machining center is easier to remove material and has relatively ideal machining conditions.
When the vertical machining center processes the cavity or the concave surface, the chips are not easy to discharge. In severe cases, the tool will be damaged, the machined surface will be damaged, and the smooth processing will be affected. Special attention should be paid to the installation of the tool and the clamping of the workpiece.
About the chip evacuation management: Why do we need to make sure the chip material does not stick to the inside of the machine cabin, to the fixture, to each other, or to anything really?
The primary concern with chip evacuation is that chips, or particles of the material being machined, can create a fire hazard if they build up and accumulate inside the machine cabin.
They can also cause wear on fixtures and other machine components such as servo motors or spindles. Chips sticking to surfaces inside the machine can interfere with motion or operation, leading to crashes or other mechanical damage.
Finally, chips that get trapped between fixtures and the part can cause defects such as burrs.
For these reasons, it is important to make sure the chip material does not stick to any surfaces inside the machine cabin. To achieve this, operators must evaluate the types of materials being machined and select the best type of coolant for the job, as well as employ effective chip evacuation strategies.
This can include selecting the correct size and shape of cutting tools, adjusting spindle speed, optimizing feed rates and depths, and using appropriate chip breakers.
In addition to all this, it is also important to regularly inspect and clean chips from machines that are in use.
All these steps help to ensure that chip evacuation is efficient and effective.
In general, horizontal machining centers are more expensive than vertical types, because the horizontal machining center is more complex than the vertical machining center in terms of processing technology and structure.
Secondly, there are relatively few manufacturers capable of producing horizontal machining centers. The price of horizontal machining centers with the same processing range is twice as high as that of vertical machining centers.
Vertical machining centers and horizontal machining centers are two different machining centers, and the choice is mainly based on the processing needs:
The vertical machining center occupies a small area, has a simple structure, and has a relatively low price. It is convenient for clamping work, easy to debug the program, and has a wide range of applications, but it cannot process parts that are too high. Parts and other workpieces with a relatively small volume of workpieces.
Vertical CNC machining centers features:
Tool changers for quick and easy tool change, allowing you to set up jobs with multiple tools quickly.
High-speed feed rates for faster production times and improved productivity.
Automated pallet changer that allows you to quickly switch between different jobs without the need for manual intervention.
Advanced control systems
The main advantage of vertical CNC machining centers is that they take up less floor space than horizontal machining centers. This makes them ideal for small shops with limited space. Additionally, vertical machining centers typically have a smaller footprint than horizontal machining centers, making them easier to move around and set up in your shop.
The machining condition of the horizontal machining center is relatively ideal with multiple sides machining. It can complete the machining of the remaining four surfaces except for the mounting surface and the top surface after one clamping. It is more suitable for machining box parts. After adding the angle head, it can realize the pentahedron machining. Generally speaking, if customers need to process a more complex surface finish, they will choose horizontal machining centers.
• Automated pallet changers for increased productivity and flexibility
• Modular tool holders for added versatility
• High-speed spindles for faster cycle times
• Automatic tool changers or multi-tool systems for maximum efficiency
• CNC control system with touchscreen programming for ease of use
There are several reasons to choose horizontal CNC machining centers over vertical CNC machining centers.
First, horizontal machining centers have a larger working envelope than vertical machining centers, which means that they can accommodate larger parts.
Second, horizontal machining centers typically have higher spindle speeds and faster cycle times than vertical machining centers, which makes them more efficient.
Third, horizontal machining centers are better suited for machining parts with a large surface area because they can easily access all sides of the part without having to reposition it.
Finally, horizontal machining centers have the ability to install multiple tools at once and can be equipped with automated pallet changers
When choosing a machining center, whether to choose a vertical machining center or a horizontal machining center mainly depends on what the object to be processed is.
Compared with traditional machine tools, CNC machine tools have the following characteristics and differences.
Computer numerical control - machining has revolutionized manufacturing. CNC machines often replace equipment needed for the job. Manufacturers often employ the CNC machine for production purposes.
Designed to produce large quantities, it offers effective rapid production capability, which can produce products typically produced by shaping machines, center-lathe grinders, routers, and vertical mills. The computer-numerical controls provide additional financial advantages as well as production advantages in contrast to conventional methods.
The accuracy of a machine is unparallel and its precision can be duplicated in many instances. So, it is the main product quality.
The precision of the machine must begin to be expected only if the components are accurately produced. CNC machines can satisfy these needs as well as guarantee high precision in manufacturing processes.
It is highly flexible to process parts on CNC machine tools, which mainly depends on the processing program. It is different from ordinary machine tools. It does not need CNC machine tools to manufacture CNC machine tools, replace many molds and fixtures, and does not need to readjust the machine tool frequently.
Therefore, CNC machine tools are suitable for occasions where the processed parts are frequently replaced, suitable for single-piece, small-batch production, and new product development, thereby shortening the production preparation cycle and saving a lot of process equipment costs.
Starting in CNC machining with less experience and still producing at a high quality. Products Can Be Easily Replicated Thousands of Times Conventional machining works well when you need to make a single custom piece.
If you have high production quotas where you need to cut the same part many times, CNC machining makes more sense.
CNC machinery lets you program your machines to make the same cut over and over. Conventional machinery needs help from an experienced operator to make similar pieces. And even then, there are still small differences among the parts. Less Labor is Required to Operate CNC Machinery
The machining accuracy of CNC machine tools can generally reach 0.05-0.1MM. CNC machine tools are controlled in the form of digital signals.
Every time the CNC device outputs a pulse signal, the moving parts of the machine tool move a pulse equivalent (generally 0.0O1MM ), and the average error of backlash and screw pitch of the feed transmission chain of the machine tool can be compensated by the numerical control device. Therefore, the positioning accuracy of the numerical control machine tool is relatively high.
The same batch of parts is processed, on the same machine tool, under the same processing conditions, using the same device and processing program, the tool trajectory is exactly the same, the consistency of the parts is good, and the quality is stable.
Once the design parameters and specifications have been entered into a CNC machine, it consistently executes huge quantities and affords flexible scalability.
CNC machine tools can effectively reduce the processing time and auxiliary time of parts. The five-axis linkage machining center of the spindle speed of the CNC machine tool and the range of the feed rate is large, allowing the machine tool to perform powerful cutting with a large amount of cutting. CNC machine tools are entering the era of high-speed machining.
The rapid movement and positioning of the moving parts of CNC machine tools and high-speed cutting processing have greatly improved productivity.
In addition, it is used in conjunction with the tool magazine of the machining center to realize continuous processing of multiple processes on one machine tool, reducing the turnaround time between processes for semi-finished products and improving productivity.
CNC machining requires less repair and less labor at least 50%.
The operator used special rulers and gauges that are embedded in the control levers for better precision. Advantages of CNC Machining Worker Safety The CNC machine operator is safe from any sharp parts behind a protective construction.
The operator can see what is going on in the machine tool via the glass. The operator does not necessarily need to go close to the spindle or mill. The operator does not have to come near the cooling fluids.
Some fluids are dangerous to medical care, and military and aerospace industries all require precision parts, and their tolerances must be strict to +/- .0005mm, which is difficult to achieve with traditional machining.
The main differences between manual and CNC machining are the time requirements. Since the CNC machining process is automated it can be possible to operate several machining units at once. Manual processes require a trained worker who can operate every machine.
CNC-machined parts allow for faster operations and lower costs. Nevertheless, both machining and manual machining offer distinct advantages.
When used in tandem with advanced design software, CNC machines create outputs that cannot be replicated by manual machines. Even the most gifted engineers can't use conventional machines up to the level of CNC machines because of the advanced software that they use. These machines can produce any size, shape, or texture needed.
CNC machines create outputs that cannot be reproduced by manual machines when used in tandem with advanced design software. The machines can produce a variety of sizes, textures, and shapes.
CNC machines consistently execute the desired quantities and offer flexible scalability once you input the design parameters and specifications.
CNC machines deliver quick results, making it simpler to meet high demands. They operate day and night.
After the CNC machine tool is adjusted before processing, the program is input and started, and the machine tool can automatically and continuously process until the processing is completed.
What the operator has to do is only program input, editing, part loading and unloading, tool preparation, machining status observation, part inspection, etc.
The labor intensity is significantly reduced, and the labor of the machine tool operator tends to be intellectual work. In addition, machine tools are generally combined, which is clean and safe.
Utilizing the processing of modern CNC machine tools for production management, the processing time can be accurately estimated in advance, the tools and fixtures used can be standardized, modernized management and the standardization of processing information is easy to achieve.
It has been integrated with computer-aided design and manufacturing (CAD/CAM ) is organically combined and is the basis of modern integrated manufacturing technology.
Traditional machining costs are minimal and can be used for small batches of projects. CNC machines are used to manufacture mass quantities but can be unprofitably used for comparatively small projects.
Automating CNC machining is required with a digital file with a cut-out instruction manual. CNC machine manufacturing processes, therefore, require multiple instruments and engineers and machiners to develop digital tools to interface with CNC machines.
This machine can be easily controlled via an application of digital instructions and design starts in computer software (CAD). The computer-generated 3-D model determines the dimensions required by the final piece.
Since CADCAM is included with several software programs, this allows for the production of similar programs to continue.
