On June 26, it was learned from the National Key Scientific and Technological Achievements Conference of “High-end CNC Machine Tools and Basic Manufacturing Equipment†that since its implementation in 2009 to 2016, it has applied for a total of 3956 invention patents, and has established 407 national and industry standards. 2951 new products and new technologies. According to the special target, by 2020, 80% of the high-end CNC machine tools and basic manufacturing equipment required for manufacturing in key areas such as aerospace and automobile will be based in China.
"CNC machine tools are the cornerstone of industrial modernization and their technical level represents the comprehensive competitiveness of a country, especially the five-axis linkage of high-end CNC machine tools for a country's aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment, etc. The industry has a significant influence,†said Prof. Lu Bingheng, a special technical chief at the conference.
According to Lu Bingheng's introduction, at the end of 2016, the standard of S-shaped test pieces for testing the accuracy of 5-axis linkage machine tools independently proposed by China has passed the examination and approval by the International Standards Committee, and it has achieved a breakthrough of the standard “zero†in the field of high-end CNC machine tools testing. This standard provides a reference for the processing of complex surfaces and is recognized by the international community.
The high-end numerical control machine tools represented by five-axis machining centers are used for batch demonstration applications in aircraft typical structural parts, aerospace complex and precision structural parts, and components of flying missile engines, and are used for large aircrafts, new fighter aircrafts, lunar exploration projects, etc. in China. Major national special projects and key projects provide key manufacturing equipment.
For example, in the aviation field, the successful development of the “Great Power†such as a large-size die forging press of 80,000 tons and an aluminum sheet tension drawing machine of 10,000 tons indicates that China’s aviation profile manufacturing has entered the world’s advanced ranks; The aerospace special manufacturing equipment such as complete sets of welding equipment, large-scale strong spinning equipment, automatic drilling and riveting equipment, etc. provide strong support for the success of the launch missions such as the Long March 5 and Tian Zhou No. 1; the auto stamping production line for large-scale auto parts in automobile manufacturing. With a global market share of more than 30%, it successfully exported nine production lines.
CNC system is the "brain" of machine tool equipment, and it is also the bottleneck restricting the development of China's CNC machine tool industry. To achieve the goal of "Made in China 2025", we must be able to innovate CNC systems including key technologies such as servo drives and servo motors.
According to Luo Junjie, deputy director of the Department of Equipment Industry of the Ministry of Industry and Information Technology, the major technical indicators of China's high-end numerical control systems have basically reached the international level, breaking the monopoly of foreign technologies and enabling batch matching of key functional components. In 2016, the high-end numerical control system specially supported by CNC machine tools has accumulated more than 1,000 sets, and the domestic market share has increased from less than 1% before the special launch to about 5%. The key functional components such as ball screws, guide rails and power tool holders are close to the international advanced level in terms of accuracy, reliability and other key indicators.
Luo Junjie said that the next step of CNC machine tools will pay close attention to the trend of intelligent and networked development. It will focus on the entire industrial chain layout of the machine tool industry, continue to focus on the two key service areas of aerospace and automotive, and build key industries such as the machine tool industry and military and automotive industries. The production and demand docking platform is focused on making up for major equipment shortcomings and promoting the strategic transformation and upgrading of the manufacturing industry.
