In the field of machining industry, the precision size control of drawings plays a vital role, which directly affects the assembly performance and quality of mechanical equipment. The main factor affecting the size of precision machining is the error problem, because the error problem is affected by a variety of factors, in the machine precision machining will inevitably appear a variety of error problems, so only the use of various technical measures, the precision control in a scientific range. This requires technical personnel to strictly process according to the production drawings, and strictly require the machining process flow, so as to ensure the accuracy of the size of the precision machining production drawings to the greatest extent.
Today, with the rapid development of social economy and industrial reform, the role played by precision machining has become more and more important, and China's machining industry has also made great progress, not only the quality has been greatly improved, but also greatly expanded in the scale of production. With the development of the industrialization process, the precision of precision machining is also more and more attention, therefore, it is necessary to strengthen the control of precision in the process of machining (precision machining process, the control of precision must be attached great importance, and take reasonable technical measures to solve the problems.
Content of machining and influencing factors

Understand the content of machining
In the field of mechanical processing in China, there is a clear definition of the accuracy of mechanical processing, which refers to the professional and technical personnel after the completion of the processing of mechanical parts, the use of instruments to detect the position of the parts, shape, size and related data, so as to determine the degree of compliance of the parts. Generally speaking, the main factor affecting the accuracy of machining is the various errors generated in machining, and the operators and technical units of technical processing must attach great importance to this problem. In machining, the control and grasp of precision are obviously related to the error problem of machining. Machining error is mainly reflected by the shape, size and position, it is through the use of mechanical size control to achieve the purpose of controlling the precision of machining, in ensuring the surface quality of machining, the machining size error control within a reasonable range. In the process of machining, due to the impact of the benchmark and the machining surface, it will cause the deviation of the position of the precision parts, so the verticality, position and parallelism of the precision machining must be strictly controlled.

/ Factors affecting precision machining accuracy
In the process of precision machining, there are strict requirements for various production technologies and production processes, so as to reduce or even eliminate the purpose of machining technology errors. In machining, the error between the spindle rotation is an important factor affecting the accuracy. In the process of modern mechanical production and processing, the error caused by the spindle rotation problem is very obvious, which is more obvious in high-tech and high-precision products, which is also an important factor affecting the processing. For the resulting error, the error can be reduced by processing and transforming the machinery. In addition, bearings with higher precision can also be used, which can also significantly reduce the resulting error.
In addition to the error caused by the spindle rotation, the error caused by the problem of the fixture and the tool can not be ignored. Due to the requirements of production, machining manufacturers will renovate the size, type and model of fixtures and tools to a certain extent, which will have a greater impact on the accuracy of machining. In the actual processing process, the size of the fixture and the tool are fixed, which makes it impossible to adjust the size of the fixture and the tool in the process of production and processing. This will cause a certain error flow in the mechanical processing when the technical parameters and the working environment change.
In addition, due to the process of using and installing fixtures and tools, the position of fixtures and tools will be changed, resulting in errors. Of course, the cutting force will also have a certain impact on the machining, resulting in the generation of errors, and ultimately the accuracy of the machining. Due to the influence of the external environment and temperature, the machined parts can easily affect the cutting force. The greater accuracy error is caused by the local change of the process system and the overall deformation. In the process of mechanical production and processing, if the change of the direction of the tightening degree and the insufficient stiffness of the parts are affected, the deformation of the machined parts will be caused, and the machining will produce a lot of errors, which will affect the precision control of the machining.
Technical measures to control machining accuracy
In the process of mechanical production and processing, the problem of processing accuracy must be strictly controlled, and the accuracy problem must be comprehensively considered, so the processing accuracy of each part must be greatly improved, so as to improve the accuracy of the entire mechanical equipment. In the process of machining, the original error plays an important role in ensuring the quality of machining. For mechanical components, it is necessary to classify them according to the requirements of relevant regulations, according to the material, type, model, size and use, and then develop a certain accuracy range, and control the precision error of the machined parts within this range. For the technical staff, it is necessary to determine a reasonable range of the error generated in the machining, and make reasonable adjustments to the fixture and the tool, so as to control the error within this reasonable range, and ultimately reduce the error of the part to the greatest extent. Only by controlling the errors in machining, can the precision control of machining be achieved to the maximum extent, so as to achieve the purpose of improving the precision of machining.
Compensating error method
Error compensation method refers to the use of processing means to achieve error compensation after the machining of mechanical parts, so as to achieve the purpose of reducing the error in the processing of parts. Compensation error method is a very important technical measure to solve the stiffness problem of the process. The main principle is to compensate the original error by creating a new error, so as to improve the precision control level in precision machining. Error compensation method is an important means to reduce the machining error, which has been widely used in practice at home and abroad. In domestic regulations, the original error is generally represented by a negative number, and the compensation error is specified as a positive number, so that when the original error and the compensation error are closer to zero, the smaller the machining error.
Of course, the methods of reducing errors and improving precision control are not only these two, but also the transfer error method is a more commonly used method of reducing errors. Therefore, in the actual production process, it is necessary to choose a reasonable method to reduce the error according to different situations, so as to achieve the best precision control and promote the continuous and stable development of precision machining.
Today, with the rapid development of social economy and industrial reform, the role played by precision machining has become more and more important, and China's machining industry has also made great progress, not only the quality has been greatly improved, but also greatly expanded in the scale of production. With the development of the industrialization process, the precision of precision machining is also more and more attention, therefore, it is necessary to strengthen the control of precision in the process of machining (precision machining process, the control of precision must be attached great importance, and take reasonable technical measures to solve the problems.

Now many industries of precision parts will use CNC machining production, but after CNC machining is completed, many products surface is still relatively rough, this time you need to carry out secondary surface finishing treatment.
First of all, surface treatment is not suitable for all CNC processing products, some products can be directly used after processing, and some need to be hand-polished, electroplating, oxidation, radium carving, screen printing, powder spraying and other special processes. Here are some things you should know about surface treatment.
1, improve product accuracy; After the product processing is completed, some products have a rough surface and leave a large residual stress, which will reduce the accuracy of the product and affect the precision of the match between the parts. In this case, the product surface treatment is required.
2, provide product wear resistance; If the parts usually use scenarios are interacting with other parts, long-term use will increase part wear, which also requires processing of the product surface to extend the service life of the parts.
3, improve the corrosion resistance of the product; Parts used for a long time in highly corrosive places require special surface treatment, requiring polishing and spraying of anti-corrosion materials. Improve corrosion resistance and service life of the product.
The above three points are the prerequisites for surface processing after CNC precision parts processing, and several surface treatment methods will be introduced below.
What is electroplating? What are the types and applications of electroplating?
01. What is electroplating?
Electroplating refers to the surface engineering technology of obtaining a solid metal film on the surface of the substrate by electrolysis in a salt solution containing the metallized group, with the metallized group as the cathode and the metallized group or other inert conductor as the anode under the action of direct current.
02. Why electroplate?
The purpose of electroplating is to improve the appearance of the material, while giving the surface of the material a variety of physical and chemical properties, such as corrosion resistance, decorative, wear resistance, brazing and electrical, magnetic, optical properties.
03. What are the types and applications of electroplating?

The galvanized layer is of high purity and is an anodic coating. The zinc layer plays a mechanical and electrochemical protective role on the steel matrix.
Therefore, galvanized layer is widely used in machinery, hardware, electronics, instruments, light industry and other aspects, is one of the most widely used plating species.
2. Copper plating
The copper coating is a cathode polar coating, which can only play a mechanical protection role on the base metal. The copper plating layer is usually not used as a protective decorative coating alone, but as the bottom or middle layer of the coating to improve the adhesion between the surface coating and the base metal.
In the field of electronics, such as through hole copper plating on printed circuit boards, as well as hardware technology, crafts, furniture decoration and other fields.
3. Nickel plating
Nickel plating layer is a negative polarity protective layer, which only has a mechanical protection effect on the base metal. In addition to the direct use of some medical devices and battery shells, the nickel-plated layer is often used as the bottom or middle interval layer, which is widely used in daily hardware, light industry, home appliances, machinery and other industries.

Hard chrome layer is mainly used for various measuring calipers, gauges, cutting tools and various types of shaft, loose hole chrome layer is mainly used for cylinder cavity piston failure; The black chrome layer is used for parts that need a dull surface and wear resistance, such as aviation instruments, optical instruments, photographic equipment, etc. Opalescent chromium is mainly used in various measuring tools.
5. Tin plating
Compared to the steel substrate, tin is a negative polar coating, while compared to the copper substrate, it is an anode coating. The tinning layer is mainly used as the protective layer of thin plate in the can industry, and most of the malleable iron skin is made of iron plate tinning. Another major use of tin coatings is in the electronics and power industries.
6, alloy plating
In a solution, two or more metal ions are co-precipitated on the cathode to form a uniform fine coating process called alloy plating.
Alloy electroplating is superior to single metal electroplating in crystal density, porosity, color, hardness, corrosion resistance, wear resistance, magnetic conductivity, wear resistance and high temperature resistance.
There are more than 240 kinds of electroplating alloys, but less than 40 kinds are actually used in production. It is generally divided into three categories: protective alloy coating, decorative alloy coating and functional alloy coating.
Widely used in aviation, aerospace, navigation, automobile, mining, military, instruments, meters, visual hardware, tableware, Musical Instruments and other industries.
In addition to the above, there are other chemical plating, composite plating, non-metal plating, gold plating, silver plating and so on.
What is polishing?
The surface of the items processed by CNC machining or 3D printing is sometimes rough, and the surface requirements of the products are high, so they need to be polished.
Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece in order to obtain a bright, flat surface processing method.
Polishing can not improve the dimensional accuracy or geometric accuracy of the workpiece, but for the purpose of obtaining a smooth surface or mirror gloss, and sometimes to eliminate gloss (extinction).
Several common polishing methods are described below:
01. Mechanical polishing
Mechanical polishing is by cutting, plastic deformation of the surface of the material to remove the polished convex and smooth surface polishing method, the general use of whetstone strip, wool wheel, sandpaper, etc., mainly manual operation, surface quality requirements can be used to super-fine polishing method.
Super finishing polishing is the use of special grinding tools, in the polishing liquid containing abrasive, tightly pressed on the workpiece to be machined surface, for high-speed rotation. This method is often used in optical lens molds.
02. Chemical polishing
Chemical polishing is to dissolve the microscopic protruding part of the surface of the material in the chemical medium preferentially than the concave part, so as to obtain a smooth surface.
The main advantage of this method is that it does not require complex equipment, can polish the workpiece with complex shape, and can polish many workpieces at the same time, with high efficiency.
The core problem of chemical polishing is the preparation of polishing liquid.
03. Electrolytic polishing
The basic principle of electrolytic polishing is the same as that of chemical polishing, that is, the surface is smooth by selectively dissolving small protruding parts on the surface of the material.
Compared with chemical polishing, the effect of cathode reaction can be eliminated and the effect is better.
04. Ultrasonic polishing
The workpiece is put into the abrasive suspension and placed together in the ultrasonic field, and the abrasive is ground and polished on the workpiece surface by relying on the oscillation of the ultrasonic wave.
Ultrasonic processing macroscopic force is small, will not cause workpiece deformation, but tooling production and installation is more difficult.
05. Fluid polishing
Fluid polishing relies on high-speed flowing liquid and the abrasive particles it carries to wash the surface of the workpiece to achieve the purpose of polishing.
Common methods are: abrasive jet processing, liquid jet processing, hydrodynamic grinding and so on. Hydrodynamic grinding is driven by hydraulic pressure to make the liquid medium carrying abrasive particles flow through the surface of the workpiece at high speed.
The medium is mainly made of special compounds with good flow under low pressure and mixed with abrasives, which can be silicon carbide powder.
06. Magnetic grinding polishing
Magnetic grinding and polishing is the use of magnetic abrasive under the action of magnetic field to form an abrasive brush, grinding the workpiece.

Long long agoOnce upon a time, people said that the country is an important weaponIt refers to the imperial jade seal handed down by Qin Shihuang on behalf of the heavenly power
Later, it generally refers to the jade seal carved by emperors of all dynastiesOn October 5, 2016, Sotheby's auction house auctioned the Hotan green jade seal "the treasure of the supreme emperor" used by one party after the reign of Emperor Qianlong in Hong Kong for HK $91.48 million. At that time, the auction aroused fierce opposition from many parties in China.Nowadays, the title of national heavy weapon refers to manufacturing equipment
Manufacturing equipment determines the level of processing and manufacturingThe level of processing and manufacturing is an intuitive expression of a country's national strengthHowever, what we are talking about today is only this kind of national manufacturing equipment
CNC machining centerIt can not only process and manufacture precision workpieces full of mechanical beautyCNC itself is also an exquisite and elegant industrial creation
(just a little loud)DMG GM 16|6 series six axis automatic turning centerThat's so bad
What can this CNC machining center do?Let's say soIt is known as the top industrial manufacture with the highest difficulty in R & D and manufacturing
Which can best reflect the highest level of industrial development of a countryTurbofan engineIt is polished with CNC bit by bit
As for various high-precision metal partsThere are too many to enumerateThere are turning, boring and milling, grinding and grooving
There are punching, gear shaper and testingThe tools that appear are not completely duplicatedA large CNC machining center
CNC can shape the precision and shape of complex workpieces at one time. What you eat is iron, and what you spit out is different work with high precision. However, the time is hundreds of times shorter than before, and the precision yield has been improved exponentially. The most irritating thing is that it also has adaptability and can be updated at any time.For example, in the past, if a master of worm gear wanted to make a good worm, you had to practice it for ten years and eight years. Hey, now if you want to process a completely different part and make a new process, you can sit and drink coffee. All this needs the support of equipment (tools), that is, it depends on how the manufacturing equipment of this manufacturing equipment plays with the equipmentCNC equipment: all kinds of machining tools
A CNC machining centerBe responsible for tool storage and tool change equipmentIt is called tool holder, also known as tool magazine
We all know the English word: tool magazine(in fact, the original meaning of the word magazine comes from the warehouse)To improve the working ability of CNC
In addition to pursuing more precise controlIt is also necessary to increase the capacity of the tool magazine and speed up the efficiency of tool changeThere are many ways to achieve this
According to the number of tools stored in the tool magazine and the tool taking methodCan be divided into different typesThe common ones are linear type, hat type, disc type, chain type magazine and so on
The power turret should be regarded as the smallest and most portable CNC tool magazineThe utility model is composed of a rotary cutter head and a box bodyA motor is installed in the box
The motor rotor is connected to the central shaft of the NC machine toolThe stator is fixed on the box for tool changeDMG BMT power turret with motor
A CNC machining center can install multiple power turretsThe upgraded version of the power turret is a hat type magazineIt is similar to the integration of turret and spindle head
It is a hat type tool magazine that automatically changes tools by moving the spindle up and downWhen the tool on the spindle enters the clamping slot of the hat magazineThe spindle moves up out of the tool
At the same time, the magazine rotates rapidlyWhen the tool to be replaced is aligned below the spindleThe spindle moves down so that the tool enters the spindle taper hole
After clamping the tool, the magazine returns to its original positionThe tool position of hat magazine is still limited (generally 16 34 tool positions)And it's always up and down
It takes up a lot of time and is not efficientIt also affects the working stroke of the spindleHowever, for a universal manufacturing equipment
It is not enough to add several independent tool holdersAfter all, a high-precision CNC machining center needs to coverLathe worker, milling worker, grinder worker, line drawing worker, heat treatment and other links
If you want to finish so much work at one timeDon't hide hundreds of knives with you. I'm sorry to leave the factory, okay!For CNC machining center
Linear magazine and chain magazine are its armed beltsChain magazineLarge CNC machining centers often need to carry hundreds of tools
If you don't agree, you have to take out dozens or hundreds of fancy tools to connect ironChain magazine of traditional armed belt typeStill not all competent
So there is a large combined extended automatic tool changing chain tool magazine(does such a long name seem particularly corrupt?)It is also called central warehouse tool magazine
The motor drives the winding chain at high speedQuickly send the required tool to the specified positionThen it is taken out by the mechanical arm and sent to the main shaft
Exchange positions with the tools that have been removed at the same timeTo save tool change timeWheel magazine of DMG mori
The disc magazine has been developed to the extremeThe cutter bases are evenly arranged around the huge hollow runnerOne cutter wheel can hold 40 60 cutters
In the assembly workshop of DMG moriYou can see the spectacular installation process of five or even six layer cutter wheelsOriginal title: the beauty of tool magazine: the arsenal of CNC machining center
