my country's CNC machine tool parts processing has made breakthroughs in key core technologies

In the field of automobile manufacturing, large-scale, fast and efficient CNC fully automatic stamping production lines have won batch orders for production lines in American automobile factories in international bidding with world-class companies, and have been recognized and respected by international peers. At present, the domestic market share of automobile cover stamping lines exceeds 70%, and the global market share has exceeded 30%, which has effectively promoted the independence of domestic automobile equipment.

In the field of power generation equipment, the 36,000-ton black vertical metal extruder has realized the independent production of domestic high-end heat-resistant steel large-diameter thick-walled seamless steel pipes used in 1000MW ultra-supercritical thermal power units; large-scale opening and closing heat treatment equipment has produced Asia's largest nuclear power forged rotor forgings, forming the mass production capacity of large rotors; ultra-heavy CNC vertical turning and milling compound processing machine tools, CNC heavy-duty bridge-type gantry five-axis linkage turning and milling compound machine tools, ultra-heavy CNC floor-standing milling and boring machines, ultra-heavy CNC horizontal boring and lathes, and special CNC axial wheel groove milling machines developed for the third-generation nuclear power nuclear island and conventional island equipment have solved the processing problems of nuclear power pressure vessels and hanging baskets, heat exchangers, turbine cylinders, generator rotors, etc., and have been installed and applied on many nuclear power equipment.

First, the level of medium and high-end equipment has been rapidly improved. At present, more than 10 types of equipment such as large-scale automobile cover automatic stamping lines have reached the international leading level and can completely replace imports. More than 20 categories of products, such as high-speed gantry five-axis machining centers, have basically reached the international advanced level and are capable of replacing imported products. Precision horizontal machining centers have formed core technologies of flexible manufacturing systems with independent intellectual property rights. High-speed, composite and other high-end CNC machining centers have completed phased research and development, but there is still a certain gap with the international advanced level in terms of functional performance and reliability.

Secondly, the CNC system has moved forward step by step. my country has made great progress in the research and development of medium and high-end CNC systems. Since 2010, more than 35,000 domestic medium and high-end CNC systems have been applied in key areas such as aerospace, energy, shipbuilding, and automobiles, achieving import substitution. High-performance CNC system series products such as multi-channel and multi-axis linkage have broken the foreign technology monopoly. The main technical indicators have basically reached the level of international mainstream high-end CNC systems, and have been matched with a variety of high-speed and precision CNC machine tools. High-end CNC systems have been applied in small batches in key military enterprises. The standard CNC system developed has been mass-produced, and the domestic market share has increased from 10% to 25%. Several industrialized production bases have been formed, among which Guangzhou Cnc Equipment Co., Ltd. has an annual production capacity of 100,000 CNC systems of various types, ranking second in the world.

my country's CNC systems have initially acquired the competitiveness of similar foreign products, and have achieved batch exports of CNC systems. From 2010 to 2014, a total of more than 9,600 sets of various CNC systems were exported, including nearly 700 sets of five-axis linkage CNC systems. Finally, the quality level of functional component products has steadily improved, and the variety series has been continuously improved. Domestic functional components have achieved batch matching with machine tool hosts; tool products have basically acquired the ability to provide modern cutting tools for the automotive industry. The application demonstration and batch matching of CNC systems, functional components and tools with CNC machine tool hosts will help form a complete industrial chain and promote the structural adjustment of the machine tool industry.
