Precision parts processing in the specific application is certainly the higher the accuracy, the more exquisite can reflect the level of processing and quality, in addition to the more popular with customers, generally speaking in the production of CNC machining center has a superiority and characteristics that can not be compared, the quality of its products will generally be higher, so what are the characteristics of precision parts processing?   1, the first CNC machine tool high precision mechanical parts processing efficiency is higher, CNC machine tool mechanical parts processing can additionally produce several surfaces, compared to general lathe processing can save many processes, saving time, and CNC machining center out of the parts quality is also relatively ordinary lathe to smooth many. 2, CNC machine tools high-precision mechanical parts processing in the development of new products have irreplaceable efficacy, generally through the programming can be different degrees of complexity of mechanical parts processing, ah, and change and update the design only need to change the lathe program, which can greatly shorten the product development cycle. 3, CNC machine tools high precision mechanical parts processing automation is very enough, greatly reducing the physical labor intensity of workers, workers in the processing process does not need to be like ordinary lathe that the whole control, mainly on the lathe for observation and supervision. However, the technical content of the corresponding CNC machining center is higher than that of the ordinary lathe, so it requires higher mental labor compared with the ordinary lathe. 4. The initial investment is relatively large compared with ordinary lathe, because the price of CNC lathe is very high, and its maintenance cost and the first production preparation period is long.

CNC lathe feed processing route refers to the turning tool from the point of tooling (or machine tool fixed origin) to start the movement, until the return to the point and end of the processing program after the path, including the path of cutting processing and tool cutting, cutting out and other non-cutting empty stroke path.   The feed route of cnc precision parts machining is basically along the sequence of its part contour, therefore, the focus of the work to determine the feed route is to determine the roughing and empty stroke feed route. In the CNC lathe machining, the processing route is generally determined to follow the following principles. 1. Should be able to ensure the accuracy and surface roughness of the machined workpiece. 2. Make the machining route the shortest, reduce the empty travel time and improve the machining efficiency. 3. Try to simplify the workload of numerical calculation and simplify the processing procedure. 4. For some reusable programs, subroutines should be used.

CNC (cnc precision parts machining) is a mechanical automation machine equipped with a program control system. The control system is able to logically and correctly process the program with control codes or other symbolic control instructions related to the provisions, and decode it, so that the machine tool operation and production of machined parts. English abbreviation CNC (cnc precision parts processing), is the English abbreviation for ComputerizedNumericalControl, also known as CNC machine tools, CNC lathes, Hong Kong and Guangdong Pearl River Delta area is called computer gongs. Mainly used in large-scale processing parts, its processing methods include turning the outer circle, boring, turning plane and so on these. Can write the program, more suitable for mass production, the manufacturing process is highly automated. Since 1952, the United States Massachusetts Institute of Technology developed the world's first CNC machine tools to date, CNC machine tools in the machinery manufacturing industry, especially in the automotive, aerospace, and military industries are widely used, CNC technology, both in terms of hardware and software, are in rapid development.

Precision machining is a process of altering a workpiece, and there are two classifications of cold machining and hot machining. Precision machining is a process of changing the size or performance of a workpiece with machining machinery. According to the temperature state of the workpiece to be machined, it is divided into cold machining and hot machining. Machining at room temperature, which does not cause chemical or physical changes in the workpiece, is called cold machining. Processing at a temperature higher or lower than room temperature will cause chemical or physical changes in the workpiece, called hot processing. Cold machining can be divided into cutting and pressure machining according to the difference of processing methods. Hot working commonly includes heat treatment, forging, casting and welding.

Before precision machining, we must understand many considerations, in case we have many unclear in the subsequent processing. After a clear understanding, it can better help us work, reduce the problem of failure and ensure product quality issues. Some of these and we need to pay attention to matters closely related to, so today we will seriously understand the precision parts processing must pay attention to what aspects of the matter? 1, Machinery before work to see if the moving parts are filled with lubricant, then run and check the clutch, brake there is no problem. And airlift the machine 1-3 minutes, the machinery is prohibited when there is a fault. 2, Precision machining work to maintain the correct posture, to have sufficient spirit to cope with the work, if found unwell need to immediately leave the workplace, and reflect to the leadership, the operation process must be focused on the mind, prohibit gossip, cooperate with each other, the operator should not be used in an irritable, tired state, so as not to cause accidents, to ensure operational safety. Before entering the workplace,.   3,All employees check whether their clothing meets the work requirements, and are not allowed to wear slippers, high-heeled shoes and clothing that affect safety, and those with long hair should wear a helmet. 4, Be sure to wait for all other personnel to leave the mechanical work area, and take away the debris on the workbench before starting the power to start the machinery.   5、When the machine is working, it is forbidden to put your hand into the slider work area, forbidden to take and put the workpiece by hand, and when taking and putting the workpiece in the punching die, you must use the standard tools. If you find that the machinery has abnormal sound or machine failure, should immediately turn off the power switch for inspection, mechanical start, by a person to transport and mechanical operation, others can not press the power button or foot pedal switch plate, not to put your hands into the mechanical work area or touch the moving parts of the machinery with your hands.   6, At the end of the day, the power should be turned off, and tidy up the finished products, side materials and debris on the post. Ensure a clean and safe working environment.

In understanding the precision hardware mechanical parts processing before, we need to understand what is precision hardware. Precision hardware is relative to the ordinary hardware material products, precision hardware is the hardware products with high requirements for precision, the most important feature is precision, that is, the tolerance must be within 0.05mm. Precision hardware mechanical parts processing, as the name implies, is the processing and production of precision hardware material products. Generally speaking, precision hardware processing is mainly to process and produce some parts or accessories with precision within 0.05mm. There are mainly precision plastic hardware, precision stamping hardware, precision turning hardware, etc. Precision hardware processing is a production process that requires a very high degree of precision for spare parts. In the process of processing and producing precision hardware, the precision must be strictly controlled to ensure that qualified hardware parts are obtained. So, what is the process of precision hardware processing? Specifically, there are the following steps: The first step: familiar with the processing equipment and hardware parts drawings. In order to be able to process the required precision hardware, before processing the production of precision hardware, you need to carefully view the hardware drawings, the required processing of precision ... The second step: according to the hardware parts to be processed to open material. Open material is the material, that is, according to the size of the hardware parts to be processed and processing technology to select the appropriate specifications of hardware materials.   The third step: processing precision hardware parts. Processing precision hardware is to put the material into the processing equipment, according to the size of the precision hardware to process the raw material The fourth step: the surface treatment of hardware parts. The surface treatment of the hardware parts is to process the surface of the precision hardware parts for grinding, polishing, oil spraying or electroplating, etc. In addition to completing the above steps, the processed precision hardware can be assembled and shipped.

Do you know CNC programming? CNC machine tools automatically process the parts to be processed according to the prepared processing program. We compile the machining process route, process parameters, tool path, displacement, cutting parameters (spindle rotation, feed, back feed, etc.) and auxiliary functions (tool change, spindle forward rotation, reverse rotation, cutting fluid on and off, etc.) of the part into a processing program sheet according to the command code and program format specified by the CNC machine tool, and then record the contents of the program sheet on the control medium (such as disk, magnetic bubble memory), Then it is input into the numerical control device of the numerical control machine tool to command the machine tool to process parts. This process of generating instructions from part drawings is called NC programming. The difference between CNC machine tools and ordinary machine tools in processing parts is that CNC machine tools automatically process parts according to programs, while ordinary machine tools are operated by people. We can achieve the purpose of processing different parts by changing the programs that control the machine's actions. Therefore, CNC machine tools are particularly suitable for processing small batches of parts with complex shape and high precision requirements Since the NC machine tool needs to process parts according to the program, the programmer will input the program into the NC device to command the machine tool after the program is prepared. The program is input through the control medium. Generally, NC programming can be divided into two cases: manual programming and automatic programming. Manual programming can be used for simple shapes (such as simple internal and external contours of CNC lathes, plane milling of CNC milling machines, etc.). This method is simple, easy to master, and adaptable. It is applicable to part programming with medium complexity and small calculation amount, and must be mastered by machine tool operators. Automatic programming is more complicated. It is generally used for parts with complex geometry and large calculation amount, which is difficult for human to complete. Common automatic programming software includes UG Master CAM catia, etc.

About the transformation of mechanical processing industry from extensive production to fine production? The automobile industry has experienced the development process from extensive production to fine production, and has achieved great success. The mining industry should also enter this stage of development. Fine also means quality, because high-quality products can provide better functions, more reliable performance and longer service life under the condition of consuming the same amount of physical and living labor. Energy equipment: unconventional oil and gas benefit from the adjustment of energy pattern. Breakthroughs will be made in unconventional oil and gas during the "Twelfth Five Year Plan" period, benefiting proprietary equipment manufacturers. Recommend Jerry Shares and Furui Tequipment. Energy saving equipment: emerging energy saving technologies are expected to become more concentrated. Screw expansion power technology is one of the nine core energy-saving technologies, which can efficiently recover the low temperature industrial waste heat below 150 ℃. Kaishan Shares with core technology is recommended. Mechanical: from extensive to fine reconstruction. Looking forward to the next decade, we believe that the macro environment we are facing will be different from that of the previous decade. Sinking demand, international market expansion, energy structure reform, environmental friendliness, enhancement of national defense forces, and deepening import substitution are the main environments we are facing. To grasp this trend, we should be optimistic about construction machinery, natural gas equipment, energy-saving equipment, Beidou navigation, basic accessories, basic processes, intelligent equipment and instruments. Construction machinery: It is expected to regain excess earnings in the fourth quarter. In the fourth quarter, excavators are expected to continue to surpass the seasonal characteristics, driving the recovery of excess yield of construction machinery. The basic principles of fine production include waste elimination, continuous improvement, collaborative work and communication. This is the guiding ideology of fine production. Improvement means never being satisfied with the status quo, constantly finding problems, finding reasons, proposing improvement measures, changing working methods, and constantly improving the quality of work. Improvement is a gradual progress, a subtle change, and its process is continuous and cumulative, which requires everyone's efforts.

Do you know what the material requirements for precision parts processing are? For precision parts processing, not all materials can be precisely processed. Some materials are too hard, which may break the parts if they exceed the hardness of the processing parts. Therefore, these materials are not suitable for precision processing unless they are made of special materials or laser cutting. For metal materials, the hardness of stainless steel is the largest, followed by cast iron, followed by copper, and finally aluminum. The data of precision machining can be divided into two categories: metal data and non-metal data. The processing of ceramics and plastics belongs to the processing of non-metallic materials. 1. First of all, the requirements for material hardness. For some places, the higher the hardness, the better. It is only limited to the hardness requirements of processing parts. The processing data cannot be too hard. If it is harder than the parts, it cannot be processed 2. Secondly, the material is moderate in hardness and softness, at least one grade lower than the hardness of the parts. At the same time, it depends on the role of the processed components and the reasonable selection of materials for the parts. In a word, there are still some requirements for precision parts processing. Not all materials are suitable for processing. For example, for too soft or too hard materials, the former is not necessary for processing, while the latter cannot. Therefore, the most basic thing is to pay attention to the density of the material before machining. If the density is too large, it is equivalent to a large hardness. If the hardness exceeds the hardness of the machine part (lathe tool), it will not only damage the parts, but also cause danger, such as the sharp fall of the lathe tool. Generally speaking, for mechanical processing, the material should be lower than the hardness of the machine tool, so that it can be processed.

Now, every step of our mobile phones can not be separated from precision parts processing. Many people will begin to say, what is the relationship between your mobile phones and precision parts processing? Today, the precision parts processing factory comes to talk with you. In fact, the key is very big, and the mobile phone precision machining will be used more and more in the future. Now, you should know that when it comes to mobile phones, the first thing you think of is Apple. Yes, there are many mobile phone brands, but Apple's iPhone is definitely a classic representative of mobile phones. Did you pay attention when using the iPhone? Most of the frames around his iPhone are made of aluminum alloy. Yes, yes. Whether it's the Apple 4 or the later 4S, 5, or 5S, the frames are made of aluminum alloy. A lot of friends will have doubts that the mobile phones with aluminum alloy bodies are indeed precision machined, and there are many mobile phones without aluminum alloy bodies. Do they have nothing to do with your precision machining? In fact, today I still want to say that as long as the mobile phone is more relevant, what is the relationship? Those are some precise small parts in the hand. These precision parts are invisible to everyone. It is assembled inside the mobile phone. These small parts are very small. How did he produce them? It is produced by precision machining, or even ultra precision machining, because the parts are very small and must be specially processed. Having said so much, we should understand that mobile phones and precision machining are inseparable. If not, mobile phones can not be separated. Most of the accessories related to mobile phones are also produced by precision machining. At this point, some people have doubts about what it has to do with precision machining. In fact, this is what people who do not understand our industry do not know. How this aluminum alloy frame is made? It is produced after precision machining with CNC machine tools. What about it? In fact, you can think about it now. Besides Apple, many mobile phones also use aluminum alloy bodies, including Samsung, Huawei and many other brands, and many mobile phone manufacturers even take this as a selling point. Because the aluminum alloy body is more durable than the plastic one. Of course, the mobile phone is not used for falling.
