The machine tool is a modern important mechanical processing equipment. With the high degree of automation of the machine tool, the importance of the data system becomes more and more obvious. At present, China's machine tool industry has not been involved in the field of high-end machine tools. On the one hand, the hardware technology such as tools and multi-axis is not relevant; on the other hand, the CNC system has a low degree of domestic production and cannot complete the automation manufacturing task well. With the rapid development of computer technology, the traditional manufacturing industry has undergone fundamental changes. Various industrialized countries have invested heavily in research and development of modern manufacturing technologies and proposed a new manufacturing model. In modern manufacturing systems, numerical control technology is a key technology. It integrates high-tech, computer, information processing, automatic detection, automatic control and other high-tech. It has the characteristics of high precision, high efficiency, flexible automation, etc. Automation, integration, and intelligence play an important role.
The core technology of the machine tool is the CNC system. At present, do not say the system, even the domestically produced CNC machine tools with a slightly better quality, the high-precision ball screw used, the bearings are mainly imported from Japan. However, China's own production of ball screws, bearings have problems in terms of accuracy and life. The major machine tool factories in China, the CNC system is 100% outsourcing.
After years of continuous efforts, China's CNC system has achieved great development, but more than 90% of the CNC systems supported by China's high-end CNC machine tools are foreign products, especially for high-end CNC machine tools urgently needed by the defense industry. The key factors of the performance, function, reliability and cost of machine tool equipment, and foreign countries still block the restrictions of China, which has become the bottleneck restricting the development of high-end CNC machine tools in China.
In order to accelerate the development of the numerical control technology industry, the state has issued a series of policies, including the State Council approved the implementation of the "equipment manufacturing adjustment and revitalization plan" and "high-end CNC machine tools and basic manufacturing equipment" national science and technology major special program, creating for China's CNC technology industry A good external environment, "equipment manufacturing adjustment and revitalization plan" clearly stated: "Adhere to the combination of equipment autonomy and key construction projects, adhere to the combination of independent development and introduction of digestion and absorption, adhere to the development of the whole machine and improve the level of basic support The basic principle of combining "improving the market share of basic components such as numerical control systems is an important part of implementing equipment autonomy. The national science and technology major project "High-end CNC machine tools and basic manufacturing equipment" also proposed that by 2020, the market share of domestic high-end CNC machine tools should be greatly improved.
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 domestic CNC system used in domestic and high-end CNC machine tools will have a market share of more than 60%; the domestic high-end CNC system market will have 120,000. The alternative space of Taiwan is huge in the future industry.
In summary, in the future, by determining the overall development strategy in line with the status quo of international CNC technology, establishing a development path that is in line with international standards is crucial to the development of CNC technology and industry in the 21st century. On this basis, China's machine tool industry can develop new types of development. The specific technical way of numerical control system, numerical control functional components, CNC machine tools and so on.
