Existing old machine tools and robots need to be modified. The machine tools and robots need components and CN systems. Each year, different systems need more than 270,000 sets.
In 20 years, the output of gold cutting machine tools is 177,000. Among them, the machine tool output is 14053 sets of various advanced machines, electric, liquid, gas and optical components. The demand for tools and supporting systems is very large. Only a variety of low, medium and high-grade systems are needed. 14,000 sets. In 1999, the system import value was 122 million US dollars, and the import value of 1/8 tool for the import of 690 million US dollars of gold cutting machine tools was 8.1 million US dollars. The import value of machine tool parts and accessories was 130 million US dollars. The import value of machine tool fixtures was 95 million US dollars. The meter imports are $6.5 million. In 1999, the import value of system tool machine parts and accessories, fixtures and measuring instruments was 435 million US dollars, which is equivalent to 1/2 of the import value of 980 million US dollars.
In recent years, China has made great progress in the development of systems, tools and supporting components. However, it is far from meeting the needs of social development and machine tool production. The medium and high-end machines, electricity, liquid and gas are required for machine tools. Due to the poor quality, stability and reliability of domestically produced products, users are skeptical and prefer to use imported products at high prices, especially high-speed machine tool spindle bearings, ball screws, linear rolling guides, servo motors, high-speed spindle motors, etc. import. On the system side. At present, the market demand supply situation is about 95% of the low-end economy type simple numerical control. The domestically produced system meets the requirements of the mid-range popular type machine tool. About 7% of the imported high-end systems are imported almost all except a few. (Finish)
