CNC lathe processing is a generic term for parts processing on CNC machine tools, computer-controlled machine tools are collectively known as CNC lathes in the machining industry, and whether it is specifically designed to control CNC machine tools and computers or general computers are called CNC systems, CNC lathe processing is widely used in the precision parts processing industry. The following is to introduce the process characteristics of CNC lathe precision parts processing. The program of the CNC system is prepared by professional engineers according to the material of the parts, process requirements, and machine characteristics. The CNC system program sends running or interrupt information to the machine tool to control the operation of the machine tool. After the machining work of precision parts is finished, the machine tool will stop automatically under the instruction of the program. The characteristics of the CNC machine itself determines its main role is used to process products with a certain degree of complexity, these products generally have a more complex surface, the main sister is able to some ordinary processing means can not solve the problem. CNC machining in the application of precision parts processing is the biggest feature is its ability to use perforated belt control machine tools to carry out automatic processing.

Cell phone in our daily life can be said to occupy a very important position, almost a hand phone, but do you know? Many parts of the phone are dependent on precision machining, and these applications are more and more, so what are the applications of precision machining in cell phone manufacturing? Apple cell phone can be said to be the hottest cell phone brand, and Apple's body is generally aluminum alloy frame, and whether it is 4s, or later 5s, 6, 6s are aluminum alloy body, and the aluminum alloy body is produced by precision CNC lathe precision machining. Almost all brands of cell phone aluminum alloy shell is made by precision machining, because this kind of shell is more beautiful, smooth and fall-resistant than the ordinary shell. So only the phone shell and precision machining have a relationship? In fact, not, there are very many parts we can not see in fact also has an inseparable relationship with precision machining, such as cell phones inside the very small nuts, because these nuts are actually customized according to the needs of cell phone manufacturers, almost nothing standard, and very high requirements for precision, so almost all are dependent on precision machining production, and cell phones inside the pin Pin and many other parts are to rely on precision machining.

We all know that the smaller the parts the higher the requirements for processing accuracy, and this kind of high-precision parts processing we also call it precision parts processing, because of its very high requirements for accuracy, so the performance and precision requirements of the processing machine is also correspondingly very high, and the material can not use too high strength hardness materials, such materials will improve the difficulty of processing, if more than the hardness of the processing machine, and even There is a risk of damage to the machine. So what are the requirements of precision parts processing materials? The following me to introduce you one by one; In the common processing of materials in fact, there are many kinds, but we can categorize them into metal and non-metal, metal is generally the highest hardness of stainless steel, followed by iron, again copper, and finally aluminum. And non-metallic materials, especially ceramics and plastics as the representatives of them. First of all, in terms of material hardness, in some applications of course, the higher the hardness the better, but due to the existence of a certain limit to the hardness of the machine tool, the material to be processed must not be too hard, at least not higher than the hardness of the machine tool, if higher than the hardness of the machine tool, then it is certainly impossible to process.   Secondly, not only the soft and hard degree of material to be moderate, and at least one grade lower than the hardness of the machine, but also the role of the processing device to do analysis, and then a reasonable selection of the machine. This is to ensure that the production of products is the most in line with the requirements and at the same time the most economical.

CNC precision parts processing we generally choose the material is easier to cut steel or copper, easy to cut steel is generally sulfur content or phosphorus content is relatively high steel, sulfur and manganese elements in steel is usually in the form of manganese sulfide, manganese sulfide can make the steel become more lubricious, and then easier to cut to improve its machinability, then CNC precision parts processing need to pay attention to What is it? 1, in the workpiece clamping correction, can only use the lowest speed state for correction, or manually trigger the chuck for correction, absolutely not in the high-speed state correction.   2、If you need to change the rotation direction of the spindle, you must not suddenly change the rotation direction, but stop the spindle first and then carry out.   3, the machine tool spacer should be flat, the width should be the same as the width of the bottom surface of the tool, and the tool should not extend too long when installed.   4, in CNC precision parts machining if necessary to brake the spindle rotation, must not use the method of reversing.

China's manufacturing and processing industry in recent years has been rapid development, but also step by step to industrial transformation and upgrading, is no longer just the world's processing plant, only do some low-end machining, but with the continuous progress of technology many precision machining has stepped into the world's forefront field. However, at the same time this industry also has some more obvious defects and shortcomings, which also requires our Chinese enterprises to continue to innovate and progress. Precision machining is a very important link in many manufacturing fields, such as automotive, military, medical, computer, communications and many other industries need to use precision hardware, precision parts and components. As a labor-intensive industry, precision parts, precision hardware and other products exports to China's entire export trade have a fairly important role in the proportion, and the current precision machining industry has been in the outward-looking development, that is, many companies are willing to give part of the parts to different suppliers to provide, rather than the previous reliance on their own production, precision The proportion of exports of precision parts products to China's exports is also increasing, which can almost indicate that more and more multinational companies are moving to China's precision parts manufacturing.   For a long time, China's precision machining industry are subject to the constraints of technology and talent pool, in some technology innovation can not compete with foreign large enterprises, but along with the industry competition intensified, domestic enterprises also invested a lot of money in independent research and development, and has achieved considerable results. For example, the 2m cnc gear measuring instrument developed by domestic enterprises has become a very popular precision measuring instrument in the international arena. In addition, most of the domestic precision parts processing enterprises have introduced a lot of foreign large manufacturers of instrumentation equipment, with this factor, but also to improve the accuracy and quality of our products. The survey of China National Precision Machinery Engineering Research shows that China's precision parts processing industry as a whole has made leaps and bounds, and certain aspects have reached the world's leading level.   But we should look at things from a development perspective, although we have made a lot of achievements, but we must still see the gap with Europe and the United States, Japan and other regions, as far as the domestic production of precision parts processing equipment is still far from Japan, Europe and the United States compared. And talent reserves, according to the latest recruitment data found that the machining industry recruiting people is the least of all industries, which also shows that the machining industry is the most shortage of talent. Therefore, we should further improve the self-innovation ability of enterprises, increase the talent pool, and shorten the gap with developed countries as soon as possible.

Precision parts processing is accompanied by today's manufacturing products continue to high-end, the performance of the product also began to have higher requirements, and the inevitable event, because to improve the quality of the product is bound to improve the requirements of the product parts. Precision mechanical parts processing is a very fine industry, the production process is complex, the process of fine, compared to other machine tool processing has a very obvious gap, the quality of the product error requirements are very strict. So what are the methods of precision machining? Here to introduce you one by one. 1. According to the machine tool parts to the precision machining method of classification   Installation of machine tools can be divided into the important parts of the classification: box, base, spindle, flange, sheet metal, etc..   2. According to the production process of precision machining method classification   Different equipment corresponds to different processes, generally the most common equipment is the lathe which contains a CNC lathe and ordinary lathe, and CNC and general lathe contains, planer, milling machine, grinding machine, wire cutting machine, etc.. Precision parts processing is actually the size of the product or performance change process, and according to the temperature environment in which the parts are processed, and can be divided into hot and cold processing of precision parts processing. At room temperature, we call it cold processing, and in the high or low temperature environment, we call the price of hot processing.

As people's living standards continue to improve, more and more attention is being paid to health, which has led to a significant development in the medical industry. We can see the existence of many precision parts in many medical devices today, and precision shafts can be ranked third in the medical equipment market among all applications, occupying 13% of the entire market. The medical industry is an industry that is closely related to people's lives, and it is indispensable for human beings in the past, present and future, and we believe that the production fields related to medical care will continue to develop steadily, including the precision shaft industry, of course. As a basic part of medical devices, precision shafts are bound to have a broader future as well. And because of the continuous development of the medical industry, the prospect of using precision shafts is bound to be even broader. Experts from the National Medical Device Industry Association revealed to us that both medical devices and precision shafts are part of the manufacturing industry and are part of it, but the difference is that precision shafts are the foundation of the entire manufacturing industry, while medical devices provide tools for medical units, or alternative and maintenance accessories for the human body.

We all know that machine tool processing if the operation is not careful is likely to lead to danger, in the actual operation process there are many small processing plant due to careless operation management is not strict occasionally occur tragic events, then CNC processing to pay attention to what dangers, the following small to introduce you one by one: the first, the transmission device in the actual operation of the probability of occurrence of danger is relatively large, if these components are not fully considered when the design of the gear components, drive chain and drive belt. First, the transmission device in the actual operation of the probability of danger is relatively large, the machine tool transmission is generally composed of gear parts, drive chains and drive belts, if these parts are not fully considered when the design of security, no design protection layer, the rotating part of the exposed, then there is a high probability of workers' hands, or clothing stranded into the device, thus causing injury.   Second, pressure machinery pressure parts may cause danger, generally common punching machines, crushers, molding machines, shear beds, etc. belong to the pressure machinery, because most of this equipment requires manual operation, and personnel operation can not avoid human error caused by fatigue or mood swings, so it is also very easy to happen injury accidents. Third, the danger from the machine tool is also a danger, because the machine tool is mostly high-speed cutting machinery, so its danger is great, the tool, splash, the operator stands inappropriate position leading to impact and other factors may lead to personal injury accidents.

What are the factors affecting the surface roughness of precision hardware parts, surface roughness determines the quality of the parts, the better the roughness of the parts, the higher the quality, objectively speaking, the factors affecting the surface roughness of precision hardware parts are mainly the following three aspects. First, physical factors, in the cutting process of the workpiece, the cutting edge rounding and extrusion can make the metal material deformation, which will make the surface roughness seriously deteriorate, in the processing of plastic materials will also be formed because of the formation of ribbon cutting and the formation of chip tumor, and very high hardness. The appearance of chipformers is very irregular, so they can easily cause tool marks of varying depths and widths on the surface of the workpiece. This inevitably increases the surface roughness of the product. Second, the process factors, from our precision hardware parts machining process, in fact, there are many factors will have an impact on its surface roughness, mainly tool, workpiece material, CNC machining conditions and other aspects of the factors.   Third, geometric factors, mainly subject to the shape of the tool, declination, sub-declination, etc. will be surface roughness has a greater impact.

The number of axes of CNC lathe is generally used in the industry as a standard for judging the grade of a lathe. Generally speaking, CNC lathes with more than five axes can be called high-grade lathes, while those with less than three axes are low-end lathes. In the processing industry, the sign to identify whether the production equipment is modern or not is whether the enterprise is equipped with CNC lathes, which is the consensus of the precision processing industry. The automation and intelligence of processing machine tools is the development direction of this industry, and the processing process is highly integrated. China's machine tool industry after generations of craftsmen's struggle, has been from the early founding of the country only more than 1,000 simple belt machine tools, to now have millions of machine tools. It has become the third largest machine tool producer in the world, so it can be said that it has achieved a lot, but we have to admit that our machine tools compared with some big brands of foreign machine tools, there are still obvious gaps, then the gap between domestic CNC lathes and foreign CNC lathes is mainly reflected in what aspects, the following small part to introduce you in detail:. First, the accuracy, stability are still a big gap, such as foreign high-end five-axis lathe can already reach 1500 hours zero failure, while the stability of domestic can only reach two-thirds of its level.   Second, the software system gap is also very obvious, the software system as the core of the machine tool, some of the traditional big brands such as Japan MAZAK, FANUC, Germany SIEMENS, Liebherr and other companies software system represents almost the highest level of the entire machine tool industry, most of them are machine tools and software systems packaged for sale, and the current domestic high-end machine tool software system Almost all imported from these companies.   Third, the CNC machine tool support also has an obvious gap, domestic machine tools can justifiably say that has reached the world's advanced level of more than 95%, but the remaining part is difficult to catch up, such as technology and testing, etc. is still far from the international leading level.
