Research on the development of machine tools and future prospects
Characteristics of exhibitors from foreign manufacturers When commenting on the characteristics of machine exhibits from foreign manufacturers, it is necessary to understand that the current four international machine tool exhibitions in the world are affected by regional, economic, technological and application conditions. The exhibits are different in purpose, purpose and display. For example, EMO in Europe holds the earliest, largest and strongest in the world. Exhibitors compete to display the world's latest technologies and innovative products, fully reflecting the world today. The highest level of machine tool technology. The MTS exhibition in the United States is located in the Americas, but the United States is the country with the longest economic, manufacturing, and machine tool level. NC machine tools, FMS, and CMS are all American leaders. The exhibition is smaller than EMO, but the United States. There are often innovative technologies on display to guide the development of world machine tool technology. Japan's industrial exhibition, due to Japan's later, is the country with the strongest NC machine tool and NC system technology and the largest output. It has many exports and few imports. The domestic market has small capacity, few overseas exhibitors, and few exhibits. The latest technology, innovative products, and international display are poor. China C industry MT exhibition, China is a developing country, held in 1989, started late, machine tool design, manufacturing, application technology is poor, but the 1.2 billion population is large, the market capacity is huge, the world countries (regions) exhibiting, Competing to expand sales and occupy the market, so the exhibits are mainly based on practicality and advanced nature. At the CIMT99 exhibition, the mid-range machine tool exhibits are the mainstream, and the high-end, innovation and development technologies are relatively few. It is very obvious that today's advanced, innovative and open-circuit linear motors, six-legged machine tools, super-fine and super-high-speed exhibits are far more than EM is less in IMTS and JIMTOF. Cutting-edge products are less in number. Low, medium and high-end folk exhibits are available, while medium and high-end exhibits are still able to fully display their machine tool technology, the internationality of advanced products and the development trend and market demand of machine tool technology in the world today. For example, the development trend of machine tool technology displayed by the four international machine tool exhibitions in the world is consistent with the trend shown by the exhibits of C-Mechans MT99. The main ones are: (1) adapting to high precision and miniaturization of products, and the machine tools are constantly Improve the accuracy, and is the basis for the development of high efficiency and automation. For example, the positioning accuracy of the machining center has been reduced from 0.01mm (2). On the basis of ensuring the accuracy, every effort has been made to improve the machining efficiency, and the highest speed of the machine tool is continuously achieved for the German RoderS. The company's RFM76O high-speed milling machine, (3) the fast moving of the linear motor with new components can reach 120m/min, even 16Om/min. CIMT99 exhibits the model of linear motor exhibited by Siemens, which can be as fast as 20Om/min, Japan Sodiek The company's two EDM forming machines use linear motors, fast moving 36m/milno (4) to develop new structural machine tools such as 6-legged machine tools, C-Working MT'99 on display in foreign countries without this exhibit, China Tianjin First Machine Tool Plant and Tianjin University cooperated to display three-legged machine tools, Harbin Institute of Technology exhibited 6-legged machine tools, positioning accuracy of 0.05mm; (5) development of dry cutting, semi-dry cutting machine tools, reducing the ring Contamination, there are SL-25OA turning center of Mori Seiki of Japan, HG630 horizontal machining center of Hitachi Seiki, and three sets of C28 spiral bevel gear machine of Ruoshi 0er11kon, performing dry cutting; (6) Networking of machine tools (7) Develop advanced components to improve machine tool performance; (8) Adapt to difficult material processing, develop various high-rigidity, high-precision tool holders and tools, such as exhibited at Japan Nikko Work Center The patented three-sided contact hollow shank can be used for machining center spindle 30,000 r/min. For example, S. Hunk of Germany exhibited various tool holders, among which HSK-E triangular inner hole chuck was developed, which is a special structure. At cIMT99, the United States exhibited 68 sets of various machine tools, including 12 NC lathes, 12 machining centers (2 horizontal and horizontal, 10 vertical), 7 grinding machines, 2 gear machines, etc. The characteristics of the American exhibits are high precision, high efficiency and low cost.
