The existing problems of high-end CNC lathe independently developed in China

The CNC lathe profession is a basic profession, and the elites in demand are also increasing year by year. With the acceleration of the upgrading pace of the Chinese system homework, the demand for CNC lathe is greatly increased. However, according to statistics, the market is now dominated by imports, and the development of domestic high-end CNC lathe is suffering. In such a case, the success of the CNC lathe industry should have a lot of outstanding lost.

At present, the added value of CNC lathe profession in China is relatively low, and the effect of self-developed high-end CNC lathe is not obvious. This is related to the low position of “made in China” in the world system and the low position of division of labor. Some experts have made an examination and analysis of why the market is dominated by imported CNC lathes, while the domestic CNC lathes are struggling, and obtained the following information: the State encourages the import of advanced skills and equipment, and expands the import of products of advanced CNC lathes

At present, the salary of CNC lathe elites in China is not very popular. For example, the research staff of a CNC lathe factory can get a salary of 3000 yuan in the third or second tier cities. Imagine that such a salary level can be obtained even if it is right or wrong for a high skilled type of work.

So the value of the creation of high skilled workers is more than 3000 yuan. Chinese machine tool enterprises are still unable to meet the urgent dream of engineers. During this period, a very important reason is that the domestic CNC lathe can not sell well. For products of the same model, the value of domestic products is much cheaper than that of overseas enterprises, so that the wife of the enterprise does not look at the product parameters, but only at the value can identify whether they are domestic products or foreign products. On the other hand, the management of Chinese enterprises seems not to be deeply aware of the importance of high-end skilled engineering staff.

What are CNC machining center systems in machining

Today’s CNC machining for you to understand the CNC machining center system in machining? Let’s get to know.

CNC system is the core component of machine tool. If the CNC system controls the behavior of machine tool, the CNC system can accurately control the position, angle, speed and other mechanical and switching values of machine tool. In China, all middle and high-level machine tools will be equipped with imported CNC systems, while domestic CNC systems are usually seen in low and medium-level machines. It is impossible to configure domestic CNC systems on some high-level machines, because domestic CNC systems are not as good as imported CNC systems in performance, stability and reliability, so the general manufacturers of machine tools will not equip domestic CNC systems to a high level It is a good choice to configure the imported CNC system on the advanced computer. The performance, stability and reliability of the imported CNC system are very good.

What are the imported CNC products

There are many imported CNC systems in China, only a few of which are well-known. For example, Siemens of Germany, FANUC and Mitsubishi of Japan, Baoyuan and Xindai of Taiwan are all well-known CNC systems in China. At present, FANUC numerical control system of Japan accounts for a large market share in Chinese numerical control system, followed by Siemens of Germany and Mitsubishi of Japan. These imported CNC systems use their advanced data and the performance advantages of the CNC system to quickly seize the Chinese CNC market, so the domestic CNC system has little market share in the Chinese market.

Features of imported CNC

As there are many brands of imported CNC system with similar characteristics, it seems too slow to talk about the characteristics one by one. Besides, the small editors can’t talk about it. Take the FANUC numerical control system of Japan, which is used by Chinese machine tools, for example. The FANUC numerical control system has the characteristics of high quality, high performance, full performance, application and various machine tools and machine tools. Fanuc CNC system focuses on the following aspects:

1. The structure is simple, easy to disassemble, and each control board is highly integrated, so the reliability is greatly increased, and the maintenance and exchange are simple.

2. Its CNC system is suitable for working environment temperature of 0-45, relative humidity of 75%. It can be seen that FANUC CNC system is suitable for environment strength.

3. Fanuc numerical control system is equipped with complete software comparison, which can meet the general requirements of machine tool operation.

After the above understanding of CNC processing, I hope to be able to help you.

Development and application of precision parts processing technolog

Precision parts processing technology is an advanced manufacturing technology developed to meet the needs of modern high technology, which is the basis of other high-tech practices. It comprehensively uses the new achievements in the development of mechanical technology and modern electronics, sensor technology, optics and computer and other high-tech technologies. It is the basic technology in the high-tech boundary and plays an important role in the modernization of national defense science and technology and the economic construction of the people. At the same time, as the basic technology and an important part of modern high-tech, it promotes semiconductor technology and photoelectric technology , raw material science and other technologies. The machining precision reaches 1 μ m, and the precision parts processing is completed by using precision machine tools, precision measuring tools and meters under strictly controlled environmental conditions.

Precision parts processing

When the machining accuracy reaches or exceeds 0.1 μ m, it is called ultra precision part machining. In aerospace industry, precision parts processing is mainly used to process precision mechanical parts in aircraft control equipment, such as precision mating parts in hydraulic flattening and dynamic servo organization, frame and shell of gyroscope, air flotation, liquid floating bearing components and floats, etc. The structure of aircraft precision parts is complex, the rigidity is small, the precision is very high, and the proportion of difficult to process raw materials is large. The processing efficiency of precision parts is as follows: ① the geometric form and mutual position accuracy of parts reach to micron or angular second level; ② the boundary or characteristic dimension of parts are below micron; ③ the surface micro roughness (surface uniformity height difference) of parts is less than 0.1? Micron; ④ the mutual parts can meet the requirements of coordination; ⑤ Some parts can also meet the requirements of accurate mechanical or other physical characteristics, such as the change of stiffness of torsion bar of float gyroscope, the stiffness coefficient of flexible element, etc.

In recent years, most of the automobile, mold parts and metal processing are made with CNC machine tool as the center, and most of the hole processing is made with advanced equipment such as machining center and CNC machine tool. High-speed and high-precision drilling processing has been put on the agenda. No matter which boundary of precision parts processing, the completion of high-precision and high-speed is an important competitive means to obtain user orders.

A great breakthrough in the foundry industry of CNC precision machining machine tools

Thanks to the rising level of forging technology and the cultivation of forging elites, in recent years, China’s CNC carefully processed machine tool forging industry has made a huge breakthrough. Although the market of China’s CNC forging industry has been stagnant and developing slowly in the past year, the output of forging machinery products has been increasing.

Although the development of forging machine tools in China has made positive achievements, its development still faces many restrictive problems. Compared with the overseas forging machine tools, the level of manufacturing technology of forging machine tools in China has obviously fallen, which makes its static operation speed, product accuracy maintenance and reliability of machine tools at the technical level of core operating parts There are obvious shortcomings.

At present, China’s forging machine tool enterprises lack the awareness and strength of self-determination innovation and basic review and discussion, which restricts the development of China’s forging machine tool technology. Only after a profound study of the characteristics and requirements of the product technology of the user industry, and paying attention to the discussion of basic review work, can China’s forging machine tool industry have a better development in the near future.

In addition, compared with the overseas forging machine tools, China’s forging machine tools are obviously lower in the level of manufacturing technology, which makes it have obvious deficiencies in the technical level of core operating parts, static operation speed, product accuracy maintenance and reliability of the machine tools. It can be seen that in the future, the development of domestic forging machine tools in China will start to actively seek new goals and ideas.

In order to meet the development requirements of household structure adjustment and low-carbon economy, and complete the scientific development of forging household products, the following work should be focused on:

1. Cultivate new family property and modern manufacturing service industry, so as to meet the transformation needs of downstream industries, maintain the stable and rapid development of China’s equipment manufacturing industry, and provide the basis for the establishment of modern forging family property system.

2. Build a comprehensive training network system for forging industry. Various modes of running schools really cover up the whole industry.

3. Help enterprises to use international laws such as WTO to deal with trade disputes such as anti marketing and win the right to speak in the international trading system.

4. Adhere to the principle of “go out, please come in”. On the basis of running China’s comprehensive forging industry high level forum and cross strait forging industry high level forum, further run Asia forging industry high level forum and create BRIC forging industry high level forum, and actively join the world forging industry high level forum.

5. Essentially join the international standardization work. In the 12th Five Year Plan period, several draft international forging standards led by China were submitted to the international standardization organization.

6. To carry out the credit rating appraisal of forging industry nationwide.

The decline of forging machine tool technology level is a big bottleneck, which can only be overcome. It is possible for domestic products of forging machine tools in China to break through in essence and develop rapidly in stable development.

What is the overall level of machining

The so-called machinery industry can be said to be machinery industry only if it is related to machinery processing. This industry is divided into machinery industry in broad sense and machinery industry in narrow sense. At present, China’s machinery industry can be said to be too low. Compared with the west, numerous manual workshops are mainly used for processing materials, and drawings and other industries are foreign. However, in the coastal area, although it is manual workshops, However, most of them have their own numerical control equipment, with high processing efficiency, usually mold based, and hardware.

The automatic lathe can automatically finish the multi process processing of small and medium-sized workpieces according to a certain program, automatically load and unload materials, and repeatedly process a batch of the same workpieces, which is applicable to a large number of large-scale production. Special lathe is a kind of lathe used to process the specific surface of a certain kind of workpiece, such as crankshaft lathe, camshaft lathe, wheel lathe, axle lathe, roller lathe and ingot lathe.

(1) The development is uneven, and the overall product level is low. Although the products of some enterprises have reached or are close to the international advanced level, overall, there is still a big gap between the accuracy of the mold, the roughness of the cavity surface, the production cycle, life and other indicators and the overseas advanced level.

(2) The technology and equipment are backward, and the organization and coordination strength are poor. Although some enterprises have changed their skills in recent years, the technology and equipment level is still relatively advanced, and the equipment level of some foreign-funded enterprises is not lagging behind overseas

Development of manipulator fixture

The mechanical manufacturing industry has a long development process. From the simple stone building in the ancient times to the numerical control processing in the modern industry, it is still free of the manual workshop’s homework method and enters the production stage of group production and specialized cooperation. With the change of manufacturing mode, the manipulator fixture has also experienced reform.

The earliest manipulator fixture is a special fixture mode. After the development of an era, with the development and demand of processing technology, the organization of fixture, general fixture, gradually appeared in various manufacturing enterprises. In recent years, due to the increasing implementation of numerical control equipment and the increase of processing strength and efficiency of products, the production cycle of special fixture is long, and the line points with large storage area are emerging, which makes the traditional manipulator fixture still become the barrier of production efficiency and economic benefit development of various manufacturing enterprises (look for vacuum sucker manufacturers to recommend GADA company).

At the same time, in the small batch production of a single piece, due to the small batch, the design and manufacture of manipulator clamps add research and development costs and lengthen the production cycle. Therefore, the most commonly used production mode at this time is simple production, that is, the local law on horseback guarantees the production demand at the expense of the production of goods. This is obviously not suitable for the needs of social development in today’s high-speed development of science and technology. In order to make the overall digitalization and modern processing technology of the enterprise can get faster development, it is necessary to integrate the manipulator fixture design with digitalization and modern processing technology, so KBE fixture must be vigorously promoted. As long as we can deal with a series of problems in the design and manufacturing process of manipulator fixture, many difficult problems in the manufacturing process of enterprise main products will be solved.

The quality of gold parts processing is increasing

In the future, with the development of China’s construction machinery industry, providing users with high-performance, high reliability, high mobility, good maintainability and economic equipment has gradually become the goal of manufacturers. Therefore, in order to meet the personalized needs of users, manufacturers should adopt the production mode of multi variety and small batch to develop new products with high quality and low price at the fastest speed. The most effective way to realize the above requirements is to adopt modular design principle, method and technology.

Now the application of hardware parts processing is also more and more, and in the accessories, the scope of application is also very wide, no matter how to say, improve human-machine safety, driving comfort, convenient for driver operation and technical maintenance, which not only improves the working conditions of the driver, but also improves the production efficiency. Some countries have vibration, noise, exhaust gas of construction machinery New standards have been set for emission and anti rollover and falling objects. The machining range of mechanical parts and components, as well as the accuracy must be high. Why? Because customers have high requirements for quality. Do you think that customers will choose the machining of mechanical parts with poor quality? From the perspective of our product selection, we all choose the good products, which is the idea of many people now.

AC rotating axis function of five axis CNC Machinine

I believe that friends in the industry are familiar with five axis machining center. Five axis machining center has five motion coordinate axes, namely two motion rotation axes and three straight-line motion coordinate axes. Generally speaking, according to the different installation positions of two rotation movements, it can be divided into AC combined rotation axis and BC combined rotation axis. Next, I will introduce the working range of AC rotation axis of five axis machining center 。

Working range and advantages of AC rotating axis of CNC five axis machining center

Generally, the axis around the x-axis of the five axis CNC machining center is defined as the a-axis, whose working range is + 30 ° to – 120 °. The worktable of the five axis machining center is equipped with a rotation axis, which rotates around the Z axis. We define it as the C rotation axis. The working range of the C rotation axis is 360 degrees. For the five axis machining center with a rotating axis and C rotating axis, the workpiece can be clamped once to finish machining other than the mounting surface. Generally, the minimum graduation value of a-axis and c-axis is 0.001 degrees, so that there is no angle on other surfaces except the installation surface, and complex processes such as machining inclined surface and inclined hole can be carried out. It can be realized that a-axis and c-axis and XYZ linear three-axis can do five axis linkage machining, and then complex curved workpiece can be processed. Of course, good CNC system, servo motor system and software support are required.

Structure advantage of AC rotating axis setting in five axis machining center

The advantages of the above AC rotating shaft are simple structure, good rigidity of the main shaft and low manufacturing cost. Generally, the worktable can not be set too large, and the bearing capacity is also relatively small, especially when the rotating axis a rotates to 90 degrees or more, it will bring great bearing moment to the worktable when processing workpieces.
