Although China's CNC system has made significant progress through continuous efforts, over 90% of the CNC systems used for high-end CNC machine tools in our country are foreign products, especially for high-end CNC machine tools urgently needed by the national defense industry. High end CNC systems are the key factors determining the performance, function, reliability, and cost of machine tool equipment, and foreign countries still impose lockdowns and restrictions on China to this day, Becoming a bottleneck that restricts the development of high-end CNC machine tools in China. In order to accelerate the development of the CNC technology industry, the country has introduced a series of policies, including the State Council's approval of the "Equipment Manufacturing Industry Adjustment and Revitalization Plan" and the "High end CNC Machine Tool and Basic Manufacturing Equipment" National Science and Technology Major Special Plan, which have created a good external environment for China's CNC technology industry. The "Plan for Adjustment and Revitalization of Equipment Manufacturing Industry" clearly states that adhering to the combination of equipment localization and key construction projects, adhering to the basic principle of combining independent development with introduction, digestion and absorption, adhering to the combination of developing complete machines and improving the level of basic supporting facilities, and enhancing the market share of basic components such as CNC systems are important contents of implementing equipment localization. The National Science and Technology Major Project "High end CNC Machine Tools and Basic Manufacturing Equipment" also proposes that by 2020, the market share of domestically produced high-end CNC machine tools should be significantly increased. According to the requirements of one of the major national science and technology projects, "High end CNC Machine Tools and Basic Manufacturing Equipment," by 2020, the market share of domestically produced CNC systems for medium and high-end CNC machine tools will reach over 60%; There is a replacement space of 120000 units in the domestic high-end CNC system market, and there is huge industry space in the future.
