Domestic CNC Machines Follow the World Level

In the high-end manufacturing industry, engine manufacturing has been hailed as the "crown" in the industry, and aerospace engines have become the "pearl" of the "crown." However, high-end five-axis CNC linkage machine tools that are indispensable for machining aerospace engine parts have long been monopolized by foreign manufacturers. A reporter from the Science and Technology Daily learned from the Beijing Institute of Power Machinery on the 28th that the monopoly will be broken.

The high-end five-axis CNC linkage machine has features such as high machining accuracy, accurate positioning, high cutting efficiency, and ability to process complex curved surfaces. However, the foreign CNC machine tool software control companies imposed technical restrictions on China, which affected the development of related technologies in China. For a long time, China's high-end CNC machine tools industry has been developing slowly. Including aerospace manufacturing, it has gradually formed a heavy reliance on imported equipment.

In May 2013, under the traction of major national science and technology projects, Beijing Power Machinery Research Institute, a key scientific research and production unit of the national defense industry that integrates design, testing and production, and Dalian Guangyang Technology Engineering Co. To achieve a leap-forward development of the domestic high-end machine tool industry. In the past year, the two sides have carried out in-depth cooperation by combining their advanced manufacturing technology and the advantages of machine tool equipment R&D, combined with spacecraft complex and core component manufacturing requirements. Has overcome the domestic machine tool geometric accuracy, position accuracy measurement and adjustment compensation, CNC servo parameters and process parameters match, parts of the adaptive programming and processing and other problems, greatly improving the performance of domestic CNC machine tools, so that The domestic five-axis CNC linkage machine tool tends to satisfy the aerospace product process manufacturing, as well as the needs of many military enterprises and other manufacturing industries.

Yang Jiping, deputy director of the Beijing Institute of Power Machinery, said that the first parts and components that were trial-produced by the two companies have reached the processing level of foreign five-axis CNC linkage machine tools. Next, the two sides will continue to deepen cooperation, form a space numerical control production line, and build high-end CNC machine tools that meet the needs of the space industry and have national independent property rights.
