Ultra-precision machining technology is an important foundation for the development of cutting-edge defense technology and an important technology with strategic significance. In the 1990s, the United States used large-scale precision CNC lathes to produce giant metal mirrors with nanometer precision, making the world's most powerful lasers successful for laser nuclear fusion systems. The system can be used for nuclear fusion research to develop clean new energy, and can be used for simulation experiments of nuclear weapons to replace real nuclear weapons and improve nuclear weapons. It can be seen that the importance of accelerating the development of China's ultra-precision processing technology is self-evident. In this respect, the country has lagged behind the international level of various industrial powers and cannot meet the needs of the national defense industry and various industrial fields and high-tech development. The introduction of advanced equipment from abroad is not only expensive but also limited, and the road to introduction can only be left behind forever. To others. Therefore, it is necessary to invest sufficient human and material resources to accelerate development in order to adapt to the needs of national defense modernization such as aviation, aerospace and weapons in a relatively short period of time. With the development of modern science and technology, new requirements have been put forward for ultra-precision machining technology, and its application has been extended to various fields of the national economy.
