Abstract National Major Science and Technology 04 special project, namely, high-end CNC machine tools and basic manufacturing equipment technology special project (referred to as 04 special). Miao Wei, Minister of the Ministry of Industry and Information Technology, said at the on-site meeting of the application of the special results of the 04 special results held recently that the implementation of the special project for more than eight years has achieved a number of gratifying results:
The national major science and technology 04 special project, namely the high-end CNC machine tools and basic manufacturing equipment technology special project (referred to as 04 special). Miao Wei, Minister of the Ministry of Industry and Information Technology, said at the on-site meeting on the application and promotion of the special results of 04. Recently, the implementation of the special project for more than eight years has achieved a number of gratifying results: the performance of heavy-duty forging equipment and some machine tool mainframes is close to the international advanced level; Significant breakthrough, the international gap in the function and performance of domestic CNC systems has been greatly reduced, and key functional components such as ball screws, guide rails and power tool holders are close to the international advanced level in key indicators such as accuracy and reliability. High-end CNC machine tools and basic manufacturing equipment are all equipment for manufacturing equipment. High-end CNC machine tools are more focused on cold processing, and basic manufacturing equipment refers to hot processing equipment. 04 Special applications are mainly for the four major fields of aerospace, marine, automobile manufacturing and power generation equipment manufacturing.
According to Wang Decheng, deputy head of 04, through nearly ten years of hard work, China's equipment manufacturing industry has broken through 80,000 tons of die forging presses, 36,000 tons of ferrous metal extrusion presses, and 500 tons of electroslag after a period of rapid growth. A large number of large-scale, critical and cutting-edge equipment such as casting equipment have realized high-end manufacturing achievements such as large aircraft, Beidou satellite, Tiangong-1, third-generation nuclear power and deep submersibles. The output value has replaced the United States and ranked first in the world. However, compared with the advanced level in foreign countries, there is still a certain gap between China's high-end equipment in terms of green, intelligence, supernormal, compound and service.
Wang Decheng believes that there are still some problems in China's basic manufacturing equipment, such as: high-end cutting-edge forming equipment vacancies such as new materials and new processes; hollow core components of high-end equipment, cylinders, valves, control systems, hydraulic components and pumps, etc. Must be imported. These explanations show that the constraints and bottlenecks of China's high-end basic manufacturing equipment for the development of strategic emerging industries still exist. It is necessary to rapidly promote the technological development and transformation and upgrading of high-end CNC machine tools and basic manufacturing equipment to meet the urgent needs of major national defense science and technology projects and major projects. .
Zuo Shiquan, director of the Equipment Industry Research Institute of the CCID Research Institute under the Ministry of Industry and Information Technology, said that China's high-end equipment manufacturing has achieved technological breakthroughs at the point, and some products have entered the application stage. For example, the large-scale high-efficiency CNC automatic stamping production line completed by Jinan No. 2 Machine Tool Group has achieved sales of more than 50 domestic products and exported 5 pieces. The domestic market share is over 70%, and the global market share is over 40%. The competitiveness of the automotive industry is a milestone. However, some key components and breakthroughs in processing technology and core technologies require long-term research and testing to reduce the international gap in terms of scale, stability and reliability.
Zhou Minsheng, technical department of China Machine Tool Industry Association, believes that the domestic CNC system for medium and high-end equipment has made great progress in the past two years. For example, Huazhong CNC Huazhong 8, Shenyang Machine Tool i5, Dalian Guangyang CNC system, etc., are finally expected to be realized in more important and sensitive departments. Localization of CNC systems. In terms of key functional components, China has made progress, but there is still a gap compared with the international advanced level, and import substitution can only be achieved in the middle and low-end markets.
"The main task of this year's 04 special project is to solve the back-end detection and inspection problems of high-end equipment to evaluate the quality level of a large number of new products and how to optimize the problem." Zuo Shiquan said.
