Since China listed "equipment manufacturing" as a national development strategy, China's equipment manufacturing industry has achieved rapid development. The manufacturing capabilities of many large-scale equipment have leapt to the world's advanced level, or even the world's top level, but made in China The industry as a whole is still backward, and its backwardness lies in the backwardness of precision manufacturing.

Ultra-precision processing technology is an important supporting technology for modern high-tech warfare, the foundation for the development of modern high-tech industries and science and technology, and the development direction of modern manufacturing science.

The development of modern science and technology is based on experiments, and almost none of the required testing instruments and equipment does not require the support of ultra-precision processing technology. One of the future development trends of manufacturing industry from macroscopic manufacturing to microscopic manufacturing, the current ultra-precision machining has entered the nano-scale, and nano-manufacturing is the frontier topic of ultra-precision machining. Developed countries in the world attach great importance to it.
