Talking about the Industrialization Development of Domestic Machine Tool Functional Components

With the acceleration of China's industrialization process, the equipment manufacturing industry as a pillar industry requires its faster development. As the basis of industrial machine and equipment manufacturing, CNC machine tools are developing rapidly, and the demand for functional components of domestic CNC machine tools is becoming more and more urgent. How to speed up the production of functional parts of domestic CNC machine tools, improve their comprehensive quality, and meet the needs of the development of CNC machine tools in China has become an important issue in front of the Chinese people.

Development status of domestic functional components industrialization

After nearly 20 years of technology introduction, digestion, absorption and innovation, especially after the key development of the “Eleventh Five-Year Plan”, the production of functional components of domestic CNC machine tools has already reached a certain scale, forming a relatively complete industrial group, for China. The development of medium and low-end CNC machine tools has made an indelible contribution.

The production of key components of CNC machine tools such as CNC system, tool magazine and robot, CNC tool holder and turntable, spindle unit, ball screw pair and rolling guide pair, CNC tool, etc., relative to the host, the development is lagging behind, the variety is small, and the degree of industrialization Low, the technical level is not high, compared with foreign countries, there are serious quality problems, far from meeting the market demand, especially the development demand of high-end CNC machine tool market, some products have to rely on imports. Due to the high import price of functional parts, the price of domestic CNC machine tools is high, almost losing the competitiveness in the international market, and has become the bottleneck of the development of domestic high-end CNC machine tools, which seriously restricts the pace of domestic high-end CNC machine tools.

With the development of high-speed machining technology, the traditional spindle structure has become increasingly unable to meet the requirements of high speed and high precision. Therefore, the application of high-speed electric spindle technology on CNC machine tools is increasingly widespread, and the level of domestic electro-spindle technology will inevitably affect the performance and level of host products. Another example is the tool magazine and the robot. It is a key functional component to ensure the stable and reliable operation of the machining center. Its rapidity and reliability are important factors that affect the efficient and reliable processing performance of the machining center.

The main problems in the industry of CNC functional components in China

1 Adaptability and satisfaction far from market demand

Judging from the current development trend of CNC machine tools in China, the adaptability and satisfaction of domestic functional components are far from the market demand. Mainly manifested in:

(1) There is a certain gap between the product level of functional components in China and foreign countries. Most of the functional components currently produced in China are mainly labor-intensive, with low technical content, and it is difficult to adapt to the development speed and technical requirements of domestic CNC machine tools, especially high-end CNC machine tools.

(2) China's functional components development capabilities are weak, new product development speed is slow, most functional components need to cooperate with foreign development, cooperative production, joint ventures, and even assembly. Although the situation has changed significantly in the past two years, the high-tech and latest-type functional components are still in the process of development in China, and the market share is still not optimistic.

2 China's CNC functional parts manufacturing enterprises are small

According to statistics, there are more than 70 functional parts manufacturing enterprises with fixed assets of more than 10 million yuan, accounting for less than 10% of all production enterprises. There are four kinds of "born" of functional component manufacturers in China: First, enterprises that have been developed from research institutes and colleges and universities with technical support can be called "hospital type". The characteristics of these enterprises are: they have a certain technical foundation and talent base, and there are many technological development potentials, but the production methods are weak, it is difficult to form an industrial scale in a short period of time, and there are also some gaps in cost, marketing, and service; Second, the enterprise that develops from a host factory gradually “independently” and “separated” to produce certain functional components can be called “main factory type”. These enterprises can adapt to the market demand in terms of production capacity, technological level and experience. They can form scale to a certain extent, but because they are inextricably linked with the original OEM, they often cause doubts in the competition. Affecting its market development, at the same time, its development capabilities also have certain limitations, so it is difficult to form a famous brand; third, a large number of private enterprises emerging in Jiangsu and Zhejiang, can be called "civil enterprise type." These enterprises are mainly labor-intensive and single-type, such as chain guards, pallets, fuel injection pipes, chip conveyors, lighting equipment, etc. Due to fierce competition, its quality and price can meet the market needs of medium and low-end CNC machine tools. Although the high-end products of these varieties can not be manufactured, they still need to rely on imports, but to a large extent, they have adapted to the overall needs of the current development of CNC machine tools in China; there are also some foreign joint ventures or wholly-owned enterprises that produce some of the higher-level functional components. However, the batch size is small, and there is no independent development capability, and it is difficult to become the main body and mainstream of the functional components.

3 core components rely heavily on imports

The development of China's CNC machine tool industry is remarkable. According to the data provided by China Machine Tool Industry Association, the total industrial output value was 34.423 billion yuan in 2008, and the sales value of products was 334.83 billion yuan, up 27.5% and 26.0% respectively. From 2002 to 2008, China was the world's first consumer of machine tools and the first importer. However, behind the rapid development of the industry, one fact that cannot be ignored is that the production of key components in China is still subject to people, and there is a situation in which profits are not high and products lack core competitiveness.

4 Lack of high technology content threatens industrial safety

China's machine tool exports have maintained a gratifying trend of growth year after year, but the "quantity increase and price reduction" directly reflects our technical level. The lack of a large number of core technologies and the dependence of key components directly affect the safety of China's machine tool industry. Therefore, we need to strengthen the awareness of early warning work, condense the wisdom and strength of the industry, and maintain industrial safety.

Domestic functional component industry development proposal

(1) China's CNC machine tool functional components should adhere to the development direction of the main engine to drive the market, market regulation, and policy cultivation.

Adhere to the road of private, joint venture, state-owned, joint investment, and common development. The functional component industry should aim at market demand, adopt market regulation as a means, adjust, reorganize and gradually develop in the competition, thereby expanding the scale, raising the level, and enhancing the supply capacity. The development trend of CNC machine tools in recent years is the development of high efficiency, high speed, complete sets and functional components, which must adapt to this trend. However, China's functional component enterprises have more “single-on-one”. It is recommended that all production enterprises gradually establish asset-linked enterprise groups through various cooperation and restructuring to strengthen scientific research and development capabilities and complete supply capabilities, and enhance competitiveness and market. Occupation rate.

(2) Strengthen development and scientific research, and gradually change the overall level of functional components in China.

CNC machine tool components are a high-tech product. As the functional requirements of CNC machine tools expand, the level of functional components that need to be matched with them must be greatly improved. Even the increase and improvement of many functions needs to be done through functional components. These technologies are often leading and basic, and some involve national security and national security. Therefore, in addition to the relevant scientific research and production enterprises to strengthen talent introduction and scientific research, it is recommended that the state give sufficient policy and financial support in research and development and results promotion to accelerate its development.

(3) Appropriate integration should be carried out to build several leading enterprises.

There are many manufacturers of numerical control functional components, but most of them are small in scale. They should be properly integrated to form several enterprises or enterprise groups with strong strength, strong technical development capability and high manufacturing level, and undertake the research and development and manufacture of high-end functional components. China's CNC machine tool functional parts development level is not high.

In short, the comprehensive development of numerical control functional components is an important link and a necessary stage in the development of CNC machine tools and equipment manufacturing in China, and should be highly valued by all parties. China's functional component industry has a certain foundation. After three to five years of hard work, it will surely usher in a period of comprehensive development, which will further promote the progress of China's CNC machine tools and related industries.
