Product research and development is the key to the upgrading of the machine tool industry. At present, the product research and development strength of China's machine tool industry consists of the research and development base of the enterprise, the research department of colleges and universities, and the institute of seven specialized institutes. The three are from different angles for the technology of China's machine tool industry. Progress contributes. 1. There are many examples of the company's R&D bases making achievements for product innovation and performance upgrades. For example, the high-efficiency CNC seven-coordinate six-coupling worm-type grinding wheel grinding machine developed by Qinchuan Machine Tool Group Technology Research Institute in 2002 has reached the world advanced level. Filling the gaps in international specifications; the high-precision super heavy-duty roll grinders developed by the National Technology Center of the Xianfeng Machine Tool Plant have been placed in the world's first. 2. The scientific research team of colleges and universities is known for its basic common technology, cutting-edge technology and software technology research. The company has developed products with complementary advantages and achieved the achievements of cutting-edge technology products such as virtual axis machine tools. The establishment of production and operation companies in colleges and universities, and the transformation of special excellent scientific research results into machine tool products may be a special way in the world's machine tool industry. The spiral bevel gear grinding machine developed by Central South University to achieve the world's advanced technology. Huazhong University of Science and Technology and other world-class rapid prototyping products have entered the market in a similar way. 3. The independent research unit in the machine tool industry has been undertaking basic common research and development work, and has the advantage of integrating and developing top-level products with a number of basic common technologies. After the reform of the scientific research system, it has the nature of science and technology-oriented enterprises, and its vitality is enhanced. The nanotechnology machine tool of Beijing Machine Tool Research Institute and the CNC rotary head stamping and laser compound machine tool of Jinan Foundry and Forging Equipment Research Institute are examples of China's R&D strength. The R&D capability is also embodied in the special milling machine for the special needs of the Shenzhou manned spacecraft combustion chamber, the ultra-high-travel vertical car for nuclear power boiler processing, and the special equipment for processing the world's largest caliber large-field astronomical telescope parts. All of them paid a satisfactory answer.
