Can we break through the bottleneck of machine tool functional parts?

China has become the world's largest machine tool manufacturing country for consecutive years, but it is also the world's largest importer, which shows that China's high-end CNC machine tools can not meet domestic needs. One of the constraints is that high-end functional components are also controlled by others, and a large number of them are imported from abroad. Not long ago, China Machine Tool Industry Association passed the "key points of work during the 12th Five Year Plan period (Trial)" for the machine tool industry, taking "efforts to improve the supporting capacity of medium and high-end CNC systems and functional components" as one of the key tasks of the industry during the 12th Five year plan period, and put forward the policy of "walking on two legs"

Wu Bailin, executive vice president of the machine tool association, said that "walking on two legs" is to fully mobilize resources and development enthusiasm from all aspects. While actively supporting the accelerated development of specialized enterprises, it also encourages and supports qualified machine tool host enterprises to extend the industrial chain according to their own needs and actively participate in the development of CNC system and functional component industry, So as to accelerate the development process of medium and high-end CNC system and functional component industry. Specialized enterprises should be closely combined with host factories to form an industrial alliance and a community of interests for development and application

in this regard, at the meeting organized by the machine tool association, business leaders from the functional component industry also expressed their views one after another

suggestion 1: we should avoid large and comprehensive, small and comprehensive

Zhao Meiling, general manager of Guangdong high tech Kate Precision Machinery Co., Ltd., said: "this means that we should support and encourage qualified and capable enterprises to develop and produce medium and high-end functional components and CNC systems. As long as enterprises do well, whether they are mainframe factories or functional component professional factories, they should support and promote them to accelerate their development to the medium and high-end."

but she raised two questions: one is whether the machine tool industry should take the road of "large and comprehensive" or "professional production"? Another is, what are the advantages of making functional components for OEMs

he Minjia, chairman of Guangzhou numerical control equipment Co., Ltd., said: "support the host factory to establish a numerical control system research department, develop medium and high-end numerical control software functions, and develop special processing software modules. The hardware, servo drive device and servo motor of the system should be produced and matched by the system professional factory, and it is not suitable to repeat the construction of production workshops."

libaomin, chairman of Shandong Bote Precision Industry Co., Ltd., said: "In order to speed up the development of functional components, host manufacturers can join the development of functional components if they have the ability. But I personally think that the intervention of host manufacturers in this regard should be fully considered. How to intervene? What to intervene? It is very worth studying. We should fully combine our own advantages, and avoid taking the big and comprehensive, small and comprehensive way."

suggestion 2: Mazak mode can be used for reference.

Chen Jihong, chairman of Wuhan Huazhong CNC Co., Ltd., proposed that for a long time, the development of CNC systems and CNC machine tools in China has shown a "two skin" phenomenon. The two have not formed a situation of mutual support, mutual promotion and common progress, nor a strategic cooperative relationship of development and application industry alliance and community of interests, which not only restricts the development and market competitiveness of China's CNC machine tool industry, but also restricts the development of China's CNC system industry

according to Chen Jihong, there are three modes to develop the NC system industry in the world, and each mode has its own advantages and disadvantages

one is Siemens mode. That is, the system factory specializes in the production of CNC systems of various specifications, provides various standard functional modules, and provides batch support for mainframe factories all over the world, such as FANUC, Siemens, Mitsubishi and other major manufacturers of CNC systems. The advantage of this mode is that the main engine factory and the system factory give full play to their respective advantages, which is conducive to the formation of professional and large-scale production. But the disadvantage is that the system factory and the mainframe factory are mainly trading relations, but the paper price has increased little? The two sides are not closely integrated

the second is Haas mode, that is, the main engine factory independently develops the CNC system and sells it with its own CNC machine tools. For example, Haas company of the United States and FIDIA of Italy, these companies started from the research and development of numerical control system at the beginning of their establishment. In order to promote the numerical control system, they began the production and sales of numerical control machine tools. Its disadvantage is that the CNC system of the unique brand of the main engine factory is difficult to be selected by other main engine factories

the third is the Mazak mode, that is, the main engine factory develops its own brand CNC system on the development platform provided by the system factory, and sells it together with its own CNC machine tools. For example, Japanese companies such as Mazak and Mori Seiji have carried out secondary development on the CNC system platform provided by Mitsubishi and Fanuc to form their own CNC system brands. This model not only avoids the possible shortcomings of the other two models, but also carries forward its own advantages

Chen Jihong believes that each leg of Mazar h folds in two different directions at the root and in the middle. The gram mode is the most suitable mode for the host plant to develop the CNC system industry. The key to the implementation of this model is that the system factory continuously provides CNC system platform technology for the mainframe factory, and forms an industrial alliance and community of interests jointly developed and applied by the mainframe factory and the system factory. During the "Eleventh Five Year Plan" period, central China CNC actively established strategic cooperative relations with key machine tool enterprises such as Dalian machine tool, Beiyi machine tool, Wuzhong group and Nantong machine tool, which greatly promoted the development of medium and high-end domestic CNC machine tools and CNC systems

suggestion 3: industrial policies should be tilted

Zhang Wanmou, chairman of Yantai universal machine tool accessories Group Co., Ltd., proposed that for many years, the production of functional components has been collected by another photoelectric switch, and the signal production enterprise has been struggling to move forward against the current in the environment of "emphasizing the main machine over the supporting equipment" and "emphasizing the ocean over the earth". Due to the "non primary" characteristics of the names of "accessories" and "components", it is difficult for the functional component industry to enjoy the attention of "main body"

although the support has been increasing in recent years, due to the weak foundation of relevant production enterprises, small scale, weak independent innovation ability, insufficient technology investment and other reasons, the effect is not satisfactory, and the industrialization supporting capacity is far from being formed

therefore, in order to develop the functional component industry and fully mobilize the enthusiasm of production enterprises, we should first give them the same attention as the host, and give a certain preference in industrial policies

secondly, to develop the functional component industry, we must make a difference in the construction of the industry university research application alliance system, and its ultimate goal is application. Therefore, it is suggested that the government should introduce some policies to encourage industry users to adopt domestic CNC machine tools and functional components, and give more opportunities to domestic functional components. At the same time, the functional component enterprises themselves should also make more efforts in close cooperation with the host plant, from point to area, strive to produce a demonstration effect in application, and gradually improve the supporting capacity

finally, the functional component factory should form a strategic alliance with the main engine factory to speed up the development and common development, so as to improve the speed of the development of functional components. This is a very necessary way of development, but it should be said that it is not easy. The reason is that Zhang Wanmou believes that there are the following aspects: "first, the development of our market economy is not perfect; second, the rapid development in recent years has led to the illusion that there is nothing difficult to do with CNC machine tools, and they are launched one after another. As for functional components, they all rely on outsourcing. But the result of development in recent years is that we have made wedding clothes for others. More importantly, the level of our machine tools has not really improved."

suggestion 4: the host machine factory and the system factory should cooperate closely

Yu Dehai, general manager of Dalian Guangyang Technology Engineering Co., Ltd., believes that in order to develop the CNC system well, it is necessary to do system planning and achieve specialization. The CNC enterprise should cooperate closely with the host machine enterprise to better serve the host machine. Manufacturers engaged in numerical control system must study technology, machine tools, and key executive parts. Only in this way can they figure out what the numerical control system should do and solve what problems

the research and development of numerical control system is completely different from that of machine tools in terms of process, technology and process. The advantage of mainframe factory is that it has a relatively full understanding of demand. As for the view of "walking on two legs" put forward by the machine tool association, I think it is objective from the perspective of meeting the development needs of the machine tool industry. It is absolutely impossible for those who engage in software, control and hardware to engage in CNC systems without technology and machinery, which is absolutely impossible. Therefore, as a manufacturing enterprise of CNC system, we hope to cooperate closely with the host machine manufacturing enterprises and fully serve the host machine enterprises

if there is no perfect processing design and system planning, and there is no support of "specialty, precision and specialty", the industry will show beautiful scenery, which is not good. There are objective laws in this, and it is not a problem that can be solved simply by financial resources

as for encouraging OEMs to develop CNC systems, the key is to see whether OEMs have the ability in this regard. The development of high-end CNC systems requires professional R & D teams, manufacturing and production teams and application technology teams, as well as a variety of experiments, testing conditions and even the corporate culture atmosphere required for relevant technological innovation. These can not be solved with money alone, and cannot be heated up. From the past development of the industry, the main engine factory has little successful experience in developing numerical control system, and with the development of numerical control technology, it will be more and more difficult

Zhao Meiling said that someone commented on the current technical situation of China's machine tool industry: functional component enterprises used the world's top key processing equipment, but failed to produce first-class functional components; The main engine factory adopts the world's top CNC system and functional components, but it does not produce first-class machine tools. Whether it is the main engine factory or the functional component enterprise, there are too many technical and technological problems to be solved. They should give play to the advantages of "specialized" production in their respective industries, support and promote each other, achieve common progress, and work together to promote the development of the whole industry
