China cnc CNC machine tool parts processing has mastered key core technologies
China's cnc machining cnc machine tools have broken through key core technologies and formed a number of iconic products. In the field of automobile manufacturing, the large-scale fast and efficient CNC automatic stamping production line has won the bulk orders of the production lines of the American automobile local factories in the international bidding with world-class enterprises, and has been recognized and respected by international counterparts. At present, the domestic market share of automotive panel stamping lines exceeds 70%, and the global market share has exceeded 30%, which has effectively promoted the autonomy of domestic automobile equipment. In the field of power generation equipment, 36,000 tons of black vertical metal extrusion machine realizes the independent production of domestic high-end heat-resistant steel large-diameter thick-walled seamless steel tubes used in 1000MW ultra-supercritical thermal power units; large-scale opening and closing heat treatment equipment produces the largest in Asia. Nuclear power forging rotor forgings, forming a large-scale production capacity of large rotors; super-heavy-duty CNC vertical turning and milling combined machining machine developed for three-generation nuclear power nuclear islands and conventional island equipment, CNC heavy-duty bridge gantry five-axis linkage turning and milling machine tool , super-heavy-duty CNC floor milling and boring machine, super heavy-duty CNC horizontal boring lathe, special CNC axial groove milling machine, etc., solved the processing problems of nuclear voltage force vessels and baskets, heat exchangers, steam turbine blocks, generator rotors, etc. Installed on multiple nuclear power equipment.
First of all, the level of medium and high-end equipment has increased rapidly. At present, more than 10 types of equipment such as automatic stamping lines for large-scale automobile covers have reached the international leading level, and import substitution can be fully realized. More than 20 kinds of products such as high-speed gantry five-axis machining center have basically reached the international advanced level and have the level of replacing imported products. Precision horizontal machining centers form core technologies with independent intellectual property rights and flexible manufacturing systems. High-speed, composite and other high-end CNC machining centers have completed phased research and development, but there is still a certain gap between the functional performance and reliability and the international advanced level.
Secondly, the numerical control system moves forward. China has made great progress in the research and development of high-end CNC systems. Since 2010, it has realized more than 35,000 domestic high-end CNC system supporting applications in key fields such as aerospace, energy, shipbuilding and automobiles, and realized imports. Alternative. The multi-channel, multi-axis linkage and other high-performance CNC system series products have broken the monopoly of foreign technology. The main technical indicators have basically reached the level of the international mainstream high-end CNC system, and realized a variety of high-speed, precision CNC machining CNC machine tools. The high-end CNC system realizes small-volume applications in key military enterprises. The standard CNC system developed has achieved mass production, and the domestic market share has increased from 10% to 25%. A number of industrial production bases have been formed, among which Guangzhou CNC Equipment Co., Ltd. has formed an annual production capacity of 100,000 sets of various CNC systems, and its output ranks second in the world.
China's CNC system has initially competed with similar foreign products, and has realized the mass export of CNC systems. From 2010 to 2014, it has exported more than 9,600 sets of various CNC systems, including nearly 700 sets of five-axis CNC system. Finally, the quality of the functional parts has been steadily improved, and the variety series has been continuously improved. The domestic functional components have been matched with the machine tool host; the tool products have basically the ability to provide modern cutting tools for the automotive industry. The application demonstration and batch matching of CNC system, functional components and tools and CNC machining CNC machine tools help to form a complete industrial chain and promote the structural adjustment of the machine tool industry.
