Many key industrial areas of product development , depends on the level of development of high-end CNC machine tools . " Professor , Tongji University , honorary director of the Institute of Modern Manufacturing Technology Zhang Shu told ," said Science China Daily " reporters, in recent years , with the defense, aerospace, high-speed rail , automotive and mold and other important equipment manufacturing industry demand sharply growth , China's CNC machine tools has made rapid development, but in terms of high-end products still faces under less competitive situation, CNC machine tools require rapid breakthrough.
Horizontal CNC machine tools , variety and production capacity, directly reflects the comprehensive national strength. According to Institute of forward-looking industry data monitoring center statistics , over the past five years , the average annual compound growth rate of China's CNC machine tool production was 37.39% . Machine Tool Industry Outlook Industry Research Institute researcher He Danyang noted in related industries , driven by China's CNC machine tools in the future will be more than the average annual growth rate of 10% in 2015 , the National CNC system needs to reach 40 million sets , with annual sales will reach 850 billion yuan .
Institute of Machine Tool Industry Outlook Industry analysts李佩娟in the " Science in China Daily" reporters , said that the manufacturing industry in the transition to digital and intelligent process, the performance of the component parts of the device have higher requirements , including precision , surface quality . Especially in some high-tech industries , such as aerospace, communications. " Technology changes the downstream market demand , the development of CNC machine tool industry presents new challenges if the technical development of CNC machine tools can be adapted to the needs of industry transformation and upgrading , you can play a role in the promotion , otherwise it will restrict its development ." Li Peijuan said.
After years of development , China's CNC machine tool technology in high-speed , complex , precision, multi-axis and so has made significant progress and a series of breakthroughs. For example , the April 2011 held in Beijing in the 12th China International Machine Tool Show , Taechon machine tool numerical control group exhibited qmk009 arc bevel gear grinding machine , abandoned the traditional exhibition into a cylindrical grinding wheel method, using fingers or a small -diameter disc wheel wheel to grind large curve bevel gear tooth profile through multi-axis direction . Zhang Shu said: " This new product subvert the traditional concept of the principle of the curve bevel gear machining and machine tool design , soft winning, breakthrough innovation is an example of the original , not only become one of the core competitiveness of enterprises , but also so that our Hardened curve into the large bevel gear machining advanced in the world . "
For our high-end CNC machine tools less competitive situation, Zhang Shu think only of basic research is not enough. "Many companies are only interested in manufacturing machine tools , but no R & D capabilities ." Should pay attention to personnel issues. " China is now the non- engineering engineering education , making our trained personnel, engineering practice less knowledge, innovation capability is weak ." This makes our high-end CNC machine tools rely heavily on imports , and technically controlled by others. For example, some foreign high-end five-axis machine tools critical software on limiting exports to China , and even the installation site using department also has limitations .
" Most of the domestic machine tool companies care how big . Easily be thousands of people , tens of thousands of scale , while foreign companies are more pursuit of the leading technologies that make their products indispensable in the manufacture of other products . " Zhang Shu said. In his view , the current mechanism of Chinese machine tool companies compete primarily on price and quantity to win, lack of core technology. With the increase of labor and raw materials costs , corporate profits will become increasingly thin. Therefore, the mechanism of competition urgent change. In addition , the national policy for the technical development of CNC machine tool industry also has an important impact .李佩娟told reporters that although the state respectively in 2005 and 2011 on the development of CNC machine tool industry introduced a special plan , but support is still clearly insufficient , and therefore , efforts to support national policy to be further strengthened.
