China Construction machinery information

Guide: Zhang Guobao, deputy director of the national development and Reform Commission, once mentioned on many occasions in Jinan for many years that China's high-performance CNC machine tools are too dependent on foreign countries, especially CNC systems Key functional components (ball screws, servo motors, CNC tool holders, etc.) rely on imports, and have not made a major breakthrough. This situation needs to be changed

Zhang Guobao, deputy director of the national development and Reform Commission, has mentioned on many occasions that China's high-performance CNC machine tools are too dependent on foreign countries, especially the CNC system and key functional components (ball screws, servo motors, CNC tool holders, etc.) rely on imports, and there has been no major breakthrough. This situation needs to be changed urgently. Therefore, it is urgent to support the CNC system and key functional component industries

several insiders were interviewed at the 11th China International Machine Tool Exhibition held a few days ago. They learned that the machine tool industry was encouraged by the recent national plan for the adjustment and revitalization of the equipment manufacturing industry. The view of giving strong support to the machine tool industry mentioned by deputy director Zhang Guobao was reflected in the plan for the adjustment and revitalization of the equipment manufacturing industry. People from enterprises who are light enough hope that the plan can be implemented as soon as possible, At the same time, they hope to provide an application platform for domestic brands and give confidence to relevant domestic enterprises

the autonomy of key parts is related to the state-owned control power

the development and improvement of the overall technical level of CNC machine tools in China can not be separated from the support of advanced functional component industry. When analyzing the current situation of machine tool accessories in China, Zhang Wanmou, chairman of Yantai universal machine tool accessories Group Co., Ltd. (hereinafter referred to as "cigarette accessories"), pointed out that the production of functional components of CNC machine tools in China has a certain scale, and there are specialized manufacturers of motorized spindles, spindle units, CNC systems, rolling functional components, CNC tool holders, CNC turntables, etc., of which the manufacturing level of individual products is close to the international advanced level. However, on the whole, the production of functional components in China develops slowly, with few varieties and low degree of industrialization. From the comprehensive situation of accuracy indicators and performance indicators, it is not hard. At present, although the functional components of CNC machine tools such as ball screw, CNC tool rest, CNC system and electric spindle have formed a certain production scale, they can only meet the supporting needs of medium and low-grade CNC machine tools. Advanced numerical control system, high-speed precision motorized spindle, tool magazine manipulator, numerical control rotary table and high-speed protective device to measure the level of numerical control machine tools, high-speed rolling functional components and (5) when the instigation needle rotation stops, the unloading handle can be pushed back to remove the main experimental force; NC power tool holders also rely on imports, which makes it impossible to talk about industrial autonomy or state-owned control, so we must promote the industrialization of functional components

Cheng Ting, executive vice president of China Machine Tool Industry Association, analyzed that functional components such as CNC system, tool magazine and manipulator, CNC tool rest and turntable, spindle unit, ball screw pair and rolling guide rail pair, CNC tool are important components of CNC machine tools. At present, the production of functional components in China lags behind that of CNC machine tools, with few varieties and low degree of industrialization, which can not meet the market demand, and some products have to rely on imports. Due to the high import price of functional components, the price of domestic CNC machine tools remains high, almost losing the competitiveness of the international market

Yu Chengting further analyzed that the price of functional components of CNC machine tools has accounted for the main part of the price of the whole machine (it is estimated that it has accounted for about 70% of the cost of the whole machine). Due to the low grade and scale of domestic functional components, the cost is relatively not low; The price of imported functional parts is expensive, which makes the price of the whole machine rise, and the price advantage of domestic CNC machine tools is also lost. The price of CNC machine tools of the same level tends to be the same as that of products in some developed countries and regions. At present, a large number of domestic CNC machine tools purchase overseas functional components. On the one hand, there is a certain gap in product quality and level due to the lack of social supporting capacity in China; On the other hand, the main engine manufacturer selects the functional components of the designated company according to the user's requirements. Therefore, to develop functional components in China, we must first solve the problems of small production scale and scattered layout, form professional and batch production, and reduce manufacturing costs; Secondly, we should introduce advanced technology, take the path of joint venture cooperation or the combination of industry, University and research, and improve the research and development ability of new products; Third, we should straighten out the system, form joint forces, advocate strategic alliances among enterprises, and strive to expand the market

functional components can not keep up with the development of the host machine will become empty talk

Zhou Jie, the sales director and engineer of the ball screw factory of Northwest Machinery Co., Ltd., pointed out in an interview that NC functional components refer to NC system, spindle unit, NC tool rest and turntable, ball screw pair and rolling linear guide rail pair, tool magazine and manipulator, high-speed protective device, etc. They are an important part of CNC machine tools. The technical level, performance and overall social supporting level of functional components directly determine and affect the technical level and performance of CNC machine tools, and also restrict the development speed of the host machine
