“Eighteen Arhats” is the image metaphor of the people in the domestic machine tool industry in the 1950s and 1960s. It was once brilliant, and it always reminded people and companies that made outstanding contributions to the machine tool industry in that era. beautiful memories. More than half a century has passed. Today, like other fields, China's machine tool industry has undergone changes in land cover and has achieved remarkable achievements. Especially in the reform and opening up and the past decade or so, the machine tool industry as the “parent machine industry” of the manufacturing industry, a large number of enterprises have grown at high speed, and the leaders of Shenji Group, Dalian Machine Tool, Qiji Machine Tool, and Shangji Company have achieved great success. It has won a wide range of markets and reputations, especially in heavy-duty, large-scale CNC machine tools. There are countless examples in this area.

The R&D market for emerging industries is in desperate need of high-end machine tools to win the 2010 “China Machinery Industry Science and Technology Award”. For example, in the past few years, China's machine tool industry has been working hard for auto, aerospace and new energy. Major equipment such as those urgently needed by the industry has been actively tackled and achieved major results.

For example, the “Key Technology and Equipment Development of High-end CNC Grinding Machines for Steel Industry” project of Shanghai Machine Tool Works Co., Ltd. is a development plan for the development of the iron and steel industry, and the development of heavy-duty CNC roll grinders suitable for the manufacture of large-size steel plates. series. Among them, the largest super-heavy CNC roll grinder capable of top-loading 250 tons of workpieces has been listed in the national “high-end CNC machine tools and basic manufacturing equipment” major scientific and technological special project, which has recently passed the acceptance of the expert group.

During the project's R&D process, seven innovative achievements have been achieved. They are: super-heavy roll top grinding process, high-performance head and tailstock structure design, on-line precision measurement of large rolls, large-scale refinement of heavy-load bearings, The design of the grinding wheel structure of heavy-duty roll grinders, the research and development of the micro-feed system for CNC roll grinders, the development of roll grinding control software and the realization of the NC process. The project has applied for and received 8 national invention patents and 6 utility model patents.

The project has also become a “parent machine that will lay eggs under the golden egg.” During the R&D process, the machine company has mastered the core technology for the research and development of heavy-duty roll grinders, built a research and development platform for heavy-duty roll grinders, and formed a research and development and production base for heavy-duty rollers. This laid the foundation for the improvement of the technical level of the domestic grinder industry.

With the first prize, Jiji Machine Tool Co., Ltd. “The key technology and equipment of the 5-axis linkage NC machine tool for double-gantry high-torque machine spindle”, with the advanced five-axis linkage heavy cutting characteristics, can complete the precise cutting processing of complex three-dimensional surfaces and improve the workpiece The precision and finish of the processing surface meet China's major project construction requirements in the Three Gorges Project and large-scale power generation projects, ships, military and other industries. The project is the first major project in China.

For a long time, the turbine blade processing equipment required for large hydropower projects in China has been dependent on imports. The successful development of this project has broken the monopoly of foreign technology. In the past, the core technology of this mechanical transmission five-axis linkage was controlled by only a few developed countries, and the high-precision, heavy-cut machining of complex facets such as large-scale water power generation equipment, water conservancy equipment, ship propellers, automobile molds, etc., and national key investment projects in the South-to-North Water Transfer Project. The processing of key parts and components required for major equipment such as the Three Gorges Water Conservancy Project and the West-East Gas Pipeline Project urgently requires such processing machines.

Look at the key technology of high-speed precision grinding of special-shaped parts and the high-speed follow-up CNC grinding machine independently developed by Jiangxi Jack Machine Co., Ltd. This project invented a new type of highly efficient precision follow-up grinding method for special-shaped shaft parts and the grinding profile of multiple grinding heads. In the method of composite surface, ultra-high-speed grinding technology and automatic programming software for NC machining were developed. The cylindrical hydrostatic guide rail and linear motor feed system for high-speed/ultra-high-speed grinding were developed, and the hydrostatic pressure bearing was composed of high speeds. The electric spindle has developed a large-scale precision composite shaped face follow-up CNC grinding machine and an ultra-high-speed CBN follow-up CNC grinding machine, and realized industrialization. An appraisal committee composed of academicians and experts from China Machinery Industry Federation Zhou Qinzhi and other experts all agreed that the two types of equipment developed by the project have a high starting point and strong innovation, and their overall technology is at the international advanced level.

The machine tool provides high-efficiency, precision and flexible processing technology and equipment for the manufacture of large-scale, special-shaped and complex shaft parts necessary for tanks, armored vehicles, submarines, automobiles, airplanes and ships in the field of national defense industry. The project develops common technology and functional components such as hydrostatic guide rail linear motor feed system technology, multi-grinding head group machining technology, follow-up grinding technology, and high-speed/ultra-high speed grinding technology, which can be widely used in high-speed cylindrical, flat, and unintentional Various kinds of general-purpose grinding machines and grinding machines for precision parts such as crankshafts, pistons, and piston rings provide highly efficient, precise and flexible theories, methods, and techniques for grinding. It can realize the substitution of imports and greatly increase the ability of China's high-end CNC grinding equipment to participate in the international market competition.
