The quality of domestic machine tools is lower than the basic import of more than 5 axes.

Domestic machine tool service aviation industry situation is not optimistic

After the rapid development during the "10th Five-Year Plan" and "Eleventh Five-Year Plan" period, the technical capability and manufacturing level of China's machine tool industry have been greatly improved. In particular, the "State Council's Opinions on Accelerating the Revitalization of Equipment Manufacturing Industry" will be high-end CNC machine tools. It is listed as one of the 16 key development projects. Through the combination of “production, learning, research and use”, it has provided a number of applicable products for China's aerospace industry. According to relevant information, in the numerical control equipment purchased by the aviation industry in recent years, the proportion of domestic production has reached more than 85%. With the continuous improvement of the adoption rate of domestically produced equipment, it has promoted the technological progress of the machine tool industry, expanded the market share of domestically produced equipment, and also enhanced the competitiveness of the domestic machine tool industry.

But we must not see, although the domestic machine tool industry has made significant progress, but the grade is still low, compared with the advanced level of foreign countries is still a big gap. Just as Hao Ming said: “The current three-axis machine tools can basically reach all domestically produced, four-axis machine tools can meet 70%~80%, and the five-axis and above mainly rely on imports.” In addition, the product reliability is not high, and the service life is short. The control system is unstable and the quality of service needs to be further improved. The rapid development of China's economy has generated a large number of demands, which has played a very important role in promoting the machine tool industry. However, the industry still has problems such as large but not strong, and serious development of numerical control systems and functional components. Regarding this status quo, Hao Ming pointed out: "The world is optimistic about the Chinese market, coupled with the high-end products of local enterprises, which will lead to sustained high-speed growth of imports for many years. Take the large-scale aerospace industry using machine tools and cutting tools as an example. The level of machine tools and tools cannot meet the requirements of the rapid development of the aviation industry. Imported machine tools and tools occupy a large proportion. On the other hand, developed countries in the West restrict the export of key parts manufacturing equipment in the aviation field. Therefore, this is the Chinese machine tool industry. If you make a difference, you should also strive to break through the key user areas."

The state has proposed the goal of 80% localization of machine tools in the aerospace industry by 2020, which requires concerted efforts from the entire industry including CNC systems, functional components and mainframe enterprises. Hao Ming said: "The machine tool is the working machine. The state should support the machine tools needed by the aerospace industry. In addition, the company should also focus on the products, focus on developing its own strong products in the user field, and increase the investment in developing special products. Occupy the middle and high-end market in many places, otherwise the price war will be seriously dragged down in the low-end market." Even for domestic high-end machine tools, most of the key components are imported. Objectively, the imported parts are stable and reliable. Functionally, there are many products that go abroad. "But we will break through this bottleneck, otherwise we can only follow other countries." For example, Beijing University of Aeronautics and Astronautics pioneered 3D printing manufacturing aircraft large titanium parts, making China the only internationally A country that realizes the practical application of laser-formed titanium alloy large-scale main bearing components on aircraft. We believe that in the near future, China's manufacturing and China's creation will gradually replace imports, and make the contribution that Chinese aircraft operators should make.
