Recently, the Ministry of Science and Technology has determined that the four provinces and cities of Chongqing, Hubei, Liaoning, and Dongguan are the first demonstration cities and provinces for the “National Numerical Control Generation Machinery Product Innovation Application Demonstration Projectâ€. As an important equipment manufacturing base in the country, Chongqing has a good technical accumulation and industrial base in the field of CNC machinery production. It will carry out technical research and industrialization demonstration from five fields in the demonstration project: First, combine the gear manufacturing industry chain. The key and basic technology in the key, the increasingly prominent contradiction between the complex diversity of gear products and production efficiency, integrated CNC technology and modern green design, reconfigurable modular design, advanced processing technology, development of key CNC gear processing equipment and high 3-5 kinds of special mechanical equipment for efficiency, promote the upgrading of products in the machine tool equipment industry in Chongqing, and form 2 technical standards and specifications. Secondly, the high-efficiency tools for the tooth-making industry are mostly imported from abroad, which leads to the increase of the cost of gear-making. The series of high-efficiency hobs, pinion knives, shaving knives and broaches are developed to improve the tooling capacity of Chongqing tooth-making machine tools. Thirdly, in combination with the promotion and application of numerical control equipment in the gear manufacturing industry, the company developed three types of integrated intelligent control tooth production lines, improved the ability of complete sets of numerical control equipment for the machine tool equipment industry, and promoted the integrated intelligent control of the production line of the gear manufacturing industry in Chongqing to form a pilot demonstration. . The fourth is in the gear industry turning, drilling, hobbing, shaving, squeezing, gear shaping, grinding, milling and other processes, through the numerical control transformation, the use of CNC special machines for gear processing and the application of automatic loading and unloading devices , fully promote the numerical control of the tooth making process. The demonstration project will be used for typical demonstration applications in 20 manufacturing enterprises. In 4 years, 4,500 CNC machining equipments will be promoted and applied, of which 3000 CNC machine tools will be promoted to the gear processing industry in Chongqing (domestic CNC systems account for 2/3).
