Machine tool bodies, supporting components, control systems, tools, etc. are equally important. No part of the technology can be fully utilized. The history of the world's machine tools has fully proved that the reason why the machine tools of the United States, Germany and Japan are advanced is that the machine tool industry is huge because of its talented personnel and scientific research. The various departments of the society work closely with each other and scientific management. Therefore, the machine components are equipped with advanced components, control systems, tools, etc., so the machine tool industry is developing faster. The number of machine tools in the world is 1,400, of which 1 million are 7%. The world's machine tool production is about 1.5 million, of which 200,000 are machine tools, accounting for 13%. Currently, the number of robots in the world (1999) is about 707,000. It is installed and used about 70,000 units per year. In contrast, one of the major reasons for the slow development of machine tools in China in the past five years is that the design and manufacturing capabilities of machine tools are poor. Many important indispensable components, control systems, and tools are not only long-term at low levels, but many Imported, cooperative production, but lack of in-depth, systematic, thorough scientific research, digestion and innovation, so the surface progress is relatively fast, the basic basis is poor and the developed countries are very different. The main components and systems of the machine tools are currently growing with the development of technology and the improvement of machine tool technology. The market requirements for machine components, tools and systems are increasing. The most basic requirements are: (1) good performance; (2) stable quality. Reliable: (3) complete supply on demand; (4) easy to use and maintain; (5) cheap and good. (Finish)
