At present, there are 14 million machine tools in the world, 1 million NC machine tools, accounting for 7%. The world's machine tool output is 1.5 million units, and NC machine tools are 200,000 units, accounting for 13%. In the industrialized countries, the number of machine tools is high, medium, and The ratio of low-end machine tools is about 20B70B10; the ratio of high, medium and low-grade machine tools is about 5B65B30 in annual output; the ratio of low, medium and high-grade machine tools in developing countries is about 80B17B3; in production, low The ratio of medium and high-end machine tools is about 70B25B5. Japan stipulates that the average service life of machine tools is 11 years. The world needs to add new machine tools to upgrade old machine tools and develop production. In the 21st century, the ratio of high-efficiency automated machine tool demand to NC machine tools is about 85B15 per year. Industrialized countries require more NC machine tools, and relatively few developing countries. In the first half of the 21st century, accuracy, efficiency, and automation will continue to be improved by single machine and link. In the second half of the 21st century, if machine tool technology develops rapidly and the economy improves, the proportion of research and development of FMS and CIMS will continue to increase. The automobile industry will be the focus of development in the 21st century, and other industries such as aerospace, military, transportation, and energy will continue to develop. In NC machine tools, NC machine tools, machining centers, special processing machines, NC grinders, NC milling machines, etc. are in demand, especially in machining centers. Due to the concentration of processes, the productivity and productivity of the process can be greatly improved. Processing centers will continue to increase. In the 21st century, NC machine tools will continue to develop intelligently, unmanned, and integrated. Improving environmental protection has gradually come to the forefront, and the number of dry cutting and semi-dry cutting machines will continue to increase in the future. The basic concept of intelligent machine tools is shown in Figure 7. Entering the 21st century knowledge economy era, people's theory and experience will play a greater role in the innovation of machine tools and links, while the accuracy, efficiency, automation level, diversity, and complete set of machine tools The overall level of sexuality, comprehensiveness, intelligence, unmannedness and integration will continue to increase. New methods of machine design and scientific testing will also become more important.
