In the "2016-2020 China CNC Machine Tool Market Investment Analysis and Forecast Report", it is pointed out that in the development of CNC machine tools, China has broken through key core technologies and formed a number of iconic products.
In the aviation field, we have independently developed 800MN large die forging presses, 120MN aluminum alloy plate tension stretching machines and other heavy forging equipment, which fills the gap in the overall forming technology of large-scale key parts in the domestic aviation field, and provides for the development of military aircraft and the development of large aircraft. Strong guarantee. Among them, 800MN large die forging press has realized more than 30 kinds of titanium alloy key parts in aviation. The high quality aluminum alloy thick plate produced by 120MN aluminum alloy wide plate tension stretching machine has been applied to aircraft machine. Wings and other main bearing structural components, get rid of the dilemma of China's large aircraft aluminum alloy thick plate completely dependent on imports.
In the field of automobile manufacturing, large-scale fast and efficient CNC automatic stamping production line has won large-scale orders for the production line of American auto local factories in the international bidding with world-class enterprises, and has been recognized and respected by international counterparts. Currently, the automobile cover press line is domestic. The market share is over 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 machine tools for three-generation nuclear power nuclear islands and conventional island equipment, CNC heavy-duty bridge gantry five-axis linkage turning and milling machine tools , Super heavy-duty CNC floor-mounted milling and boring machine, ultra-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.
CNC machine tool product structure optimization and adjustment, the technical level has also steadily improved. First, the level of medium and high-end equipment has rapidly increased. At present, more than 10 types of equipment such as large-scale automobile cover automatic stamping line have reached the international leading level, and can completely achieve import substitution. More than 20 kinds of products such as Longmen 5-axis machining center have reached the international advanced level and have the level of replacing imported products. The precision horizontal machining center forms the core technology with independent intellectual property rights and flexible manufacturing system. High-speed, compound and other high-end CNC machining centers have Completed phased research and development, but there is still a gap between the functional performance and reliability and the international advanced level.
Secondly, the numerical control system advances step by step. China has made great progress in the research and development of medium and high-grade CNC systems. Since 2010, it has accumulated more than 35,000 domestically produced medium and high-end industries in key fields such as aerospace, energy, shipbuilding and automobiles. The supporting application of numerical control system has realized import substitution. 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 international mainstream high-grade CNC system, achieving a variety of high-speed, precision CNC machine tools. High-end CNC system realizes small-volume application in key military enterprises. The standard CNC system developed has realized mass production, and the domestic market share has increased from 10% to 25%. Several industrial production bases have been formed, including 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, functional components The product quality has been improved steadily, 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. CNC systems, functional components and tools and CNC machine tools Application demonstration and batch matching will help to form a complete industrial chain and promote the structural adjustment of the machine tool industry.
According to the report, the current demand structure of downstream users in the machine tool industry has developed in a high-end manner. Many industries will carry out large-scale, deep-level structural adjustments and upgrades. The demand for high-quality, high-tech machine tool products is urgent. The demand for medium and high-end CNC machine tools is rising rapidly. Users need more high-speed, high-precision, composite, flexible, multi-axis linkage, intelligent, high-rigidity, high-power CNC machine tools, and have broad development prospects.
For example, the automotive industry has shown a trend of producing large quantities, multiple varieties, and rapid vehicle models, and the development of new energy vehicles is accelerating, which requires processing equipment to develop in a precise, efficient, and intelligent direction. In the aerospace industry, with The surge in demand for civil aircraft and the intergenerational development of military aircraft, the new generation of aircraft is moving towards light weight, high reliability, long life, high stealth, multi-configuration, fast response and low-cost manufacturing. The first generation of technology urgently needs more advanced processing equipment to carry, and aviation manufacturing equipment is developing towards automation, flexibility, digitization and intelligence. For example, in the manufacture of aircraft engines for the 'two-machine special' breakthrough, engine blades, Typical parts such as machine casings and leaf discs are gradually becoming larger in size, complicated in profile, lightweight in construction and precision in manufacturing, especially in the application of new lightweight materials such as high-strength high-temperature heat-resistant alloys. The geometrical configuration of the structural members is complex and difficult to machine, and new requirements are imposed on high-torque, high-precision CNC machine tools. Large structural parts for gas turbines And the portability of the large-scale equipment for remote maintenance or the movable multi-axis linkage numerical control equipment. This kind of machining design of a large-sized workpiece with a small machine tool without a fixed base and reconfigurable assembly is designed for the structure of the new numerical control equipment. Process specifications and energy efficient processing techniques present greater challenges.
