CNC machine tool industry is ready to break

In recent years, with the rapid growth in the demand for major equipment manufacturing industries such as national defense, aviation, high-speed rail, automobiles, and molds, China's CNC machine tools have also achieved rapid development. However, in the case of high-end products, they are still facing a situation where competitiveness is not strong. CNC machine tools need to make rapid breakthroughs.

The level, variety, and production capacity of CNC machine tools directly reflect the country's overall strength. According to statistics from the Industrial Development Research Center of the Foresighted Industry Research Institute, the average annual compound growth rate of China's CNC machine tool production in the past five years was 37.39%. He Danyang, a researcher of the CNC machine tool industry at the Industry Research Institute pointed out that under the drive of related industries, the average annual growth rate of CNC machine tools in China will exceed 10% in the future, and by 2015, the demand for CNC systems in China will reach 400,000 units. Will reach 850 billion yuan.

Li Peijuan, an analyst of the CNC tool industry at the Industrial Research Institute, said in an interview with a reporter from the China Science Journal that during the transition from digitization to intelligence, the manufacturing industry has higher requirements on the performance of equipment components, including precision. , surface quality, etc. Especially in some high-tech industries, such as aerospace and communications. “The change of technology demand in the downstream market poses new challenges to the development of the CNC machine tool industry. If the technological development of CNC machine tools can adapt to the needs of the transformation and upgrading of the manufacturing industry, it can play a promoting role, and vice versa will constrain its development.” Li Peijuan said.

After years of development, China's CNC machine tool technology has made significant progress and a series of breakthroughs in terms of speed, compoundness, precision, and multi-axis. For example, at the 12th China International Machine Tool Exhibition held in Beijing in April 2011, the qmk009 CNC arc bevel gear grinding machine exhibited by Taichuan Machine Tools Group abandoned the conventional cylindrical grinding wheel for grinding. The method uses a finger-shaped grinding wheel or a small-diameter disk-shaped grinding wheel to grind a large-sized curved bevel gear along a tooth profile through multi-axis linkage. Zhang Hao said: "This new product subverts the principle of traditional curve bevel gear machining and the concept of machine tool design. Winning with softness and making breakthroughs is an example of original innovation. It not only becomes one of the company's core competitiveness, but also makes our country Entered the world of large-scale hard-toothed bevel gears.

For the situation where China's high-end CNC machine tools are not competitive, Zhang Jian believes that only basic research is not enough. "Many companies are only concerned with manufacturing machine tools but they do not have R&D capabilities." More attention should be paid to talent issues. “Now the non-engineering of engineering education in China has led to less talented people, less practical engineering knowledge, and weaker innovation capabilities.” This has led to a large number of high-end CNC machine tools being imported and technically controlled. For example, some of the key software of high-end five-axis linkage machines in foreign countries restricts the export to China. There are even restrictions on the use of departments and installation sites.

“Most domestic machine tool companies are concerned about how to make it bigger. There are thousands of people and tens of thousands of people at a time. Foreign companies are more eager to lead the technology, that is, to make their products indispensable in the production of other products. "Zhang Hao said. In his opinion, the current competition mechanism of China's machine tool companies mainly depends on price and quantity, and lacks core technologies. With the increase in labor, raw materials and other costs, corporate profits will become increasingly thin. Therefore, the competition mechanism needs to be changed. In addition, the national policy also has an important influence on the technological development of the CNC machine tool industry. Li Peijuan told reporters that although the state has issued special plans for the development of the CNC machine tool industry in 2005 and 2011 respectively, the support is still insufficient. Therefore, the support of the national policy needs to be further strengthened.
