Domestic high-speed punches continue to break through the monopoly situation

    At present, my country has become the world's largest consumer of machine tools and a large importer of high-speed punches. The CNC system is an important part of high-speed punches, and its cost accounts for 30% to 50% of the total cost of machine tools.

    Statistics show that about 70% of domestic high-end CNC systems are occupied by overseas CNC companies, and some high-end high-speed punches are still regarded as strategic materials and are subject to embargo restrictions in the international market. The five-axis linkage high-speed punching machine is one of the high points of high-speed punching technology. It is a five-axis linkage milling machine used for processing large-scale propeller space surfaces.

    According to industry insiders, three major technological breakthroughs have been achieved in this major technical equipment with completely independent intellectual property rights: First, the equipment’s ultra-heavy, high-precision spindle box has a large weight, high strength and rigidity requirements, and has reached the current level. The limit of the world's headstock manufacturing; second, the manufacturing process research and accuracy of the ultra-long bed has reached the domestic leading level. The machine bed is 45 meters long, the error of the guide rail reaches any length of 1 meter does not exceed 0.015 mm, the error does not exceed 0.16 mm within any length of 20 meters, and the error does not exceed 0.27 mm within a length of 45 meters; the third is the first domestic double working group Three-channel numerical control technology and three-axis synchronization technology.

    "Compared with developed countries, we are speeding up to catch up. The successful development of some products even made foreign counterparts panic, not only breaking their long-term monopoly in the domestic market, but also forcing them to lower the price of their products." Said Yu Chengting, executive vice chairman of the Tool Industry Association.

    "Chinese CNC companies are confident and capable of breaking the monopolies and technical barriers of foreign companies, using the Chinese "brains" we have developed to equip our country's leading equipment and breaking through foreign blockades," said the person in charge of Wuhan Huazhong CNC Co., Ltd. Huazhong CNC takes the technical route of using general industrial microcomputer as the hardware platform, and has achieved a breakthrough in CNC system technology through the innovation of software technology. Using general industrial computers and electronic devices, we independently developed a 4-channel, 9-axis linkage "Huazhong 1" high-performance CNC system that broke the foreign blockade, reaching the international advanced level.

    Tentacles continue to extend

    Not only that, my country's high-speed press products have been extended to complete sets.

    CNC super-heavy-duty machine tools are key equipment for major equipment manufacturing and heavy weapons manufacturing such as water, fire, nuclear power plant equipment manufacturing, shipbuilding, metallurgy and mining, and my country has become one of the few super-heavy-duty machine tool suppliers. The DL250 5m CNC super heavy horizontal boring lathe is a new product independently developed and manufactured by Wuzhong Group. It is the largest super heavy CNC horizontal lathe in the world so far. The total weight of the machine is 1450 tons, of which the weight of the spindle box can reach 177 tons, the spindle end face runout and radial runout are both within 0.008 mm.
