Although China has been ranked as the world's largest consumer of metal processing machine tools and the largest importer in the world for nine consecutive years, the overall situation of large but not strong, numerically controlled system and the development of key functional components has significantly restricted the sustainable development of the industry. .
In terms of product types, compared with the advanced level of foreign countries, the overall level of the host has a large gap. There are few companies that can provide users with complete sets and line-up services. They lack the ability to provide complete solutions or undertake more complex engineering general contracting projects. The medium and high-end Cnc Machine tools that are urgently needed in the market mainly rely on imports. The main imported products are: machining centers, CNC lathes, precision grinding machines and special processing machines. The lagging development of CNC systems and functional components has become a bottleneck restricting the development of the industry. The domestic market share of domestic mid-range CNC systems is only 35%, while more than 95% of high-end CNC systems rely on imports. The overall market share of the functional components is about 30%, and the market share of high-end functional components is lower. Brand features in Taiwan account for about 50% of the domestic market, and the remaining 20% ​​are brand products such as the EU and Japan.
However, the key technologies of high-end CNC machine tools characterized by high speed, high precision, compound and intelligence have made significant progress, and a number of common, basic technologies and new product developments have made new progress, but compared with the international advanced level, There is a big gap. Some key technologies, such as high-speed and high-precision motion control technology, dynamic integrated compensation technology, multi-axis linkage and composite processing technology, intelligent technology, high-precision direct drive technology, and reliability technology, need further breakthroughs. Some major technologies are separated from the industry. There is still a long way to go. The research and development system that takes enterprises as the main body, market-oriented, and combines production, education and research has not been established. The independent innovation and development of the industry lacks high-tech support.
With the theme of scientific development as the main line, we will accelerate the transformation of development mode, take the strategic adjustment of the structure as the main direction, and take the road of "two integrations and integrations". Seize the important strategic opportunities for the development of the industry, with the development of CNC machine tools as the leading, the mainframe as the leader, and the perfect supporting basis, focusing on breaking through the weak links of CNC systems and functional components, and accelerating the industrialization of high-end CNC machine tools. Relying on major science and technology projects, we must adhere to scientific and technological progress and independent innovation. Strengthen the construction of innovative talents, enhance the core competitiveness of enterprises, and promote the transformation of China from a large machine tool to a powerful country.
