As we all know, product development is the key to upgrading the machine tool industry. At present, the product R&D strength of China's machine tool industry consists of the company's R&D base, research institutes of universities and research institutes set up by seven institutes. These three companies contribute to the technological progress of China's machine tool industry from different angles.

1. There are many cases where the company's R&D base has made achievements in product innovation and performance upgrades. For example, the Qinchuan Machine Tool Group Technology Research Institute developed a highly effective CNC seven-coordinate six linkage worm gear grinding machine in 2002 that has reached the world advanced level. Filling the blanks of international specifications; The high-precision super-heavy roll grinder developed by the National Technology Center of Xianfeng Machine Tool Plant has been equipped with a proprietary copyrighted CNC system to enter the world's advanced ranks.

2. Scientific research teams in universities and colleges are known for their basic common technology, cutting-edge technology, and software technology research. They combine product development with companies to complement each other's advantages and have achieved advancements in virtual-axis machine tools and other cutting-edge technology products. The practice of setting up production and operation companies in universities and colleges, transforming special scientific research achievements into machine tool products may be a special method in the world machine tool industry. The spiral bevel gear grinding machine developed by Central South University has reached the world advanced technology. Huazhong University of Science and Technology and other world-class rapid prototyping products are entering the market with similar production and management methods.

3. The independent research unit in the machine tool industry has always undertaken basic common research and development work, and has the advantage of integrating and developing top-level products based on a number of basic common technologies. After reforming the scientific research system, it has the nature of a science and technology pilot enterprise and its vitality has been enhanced. The nanometer technology machine tool of Beijing Machine Tool Research Institute and the CNC rotary head stamping and laser compound machine tool of the Jinan Foundry Press and Forging Equipment Research Institute are examples of the strength of R&D in China. The research and development capability is also embodied in special types of milling machines for the special needs of China's manned spacecraft combustion chamber, special high-end vertical lathes for nuclear power boiler processing, and the world's largest caliber large-field astronomical telescope parts processing equipment. All of them handed in a satisfactory answer sheet.
