Development trend of CNC machine tools

The domestic production of metal processing machine tools decreased by 2% year-on-year, among which the production of metal cutting machine tools decreased by 1.7% year-on-year, and the production of metal forming machine tools decreased by 3.3% year-on-year. في نفس الوقت, the demand for imported machine tools in the domestic market has increased instead of decreased. في 20124, the total import value of machine tools was 17.78 billion US dollars, an increase of 10.8% year-on-year. Among them, the import value of metal processing machine tools was 10.83 billion US dollars, an increase of 7.6% year-on-year. This indicates that the domestic machine tool industry is difficult to meet the high-end needs of enterprises, and is under the dual pressure of cyclical and structural pressures, urgently seeking new development breakthroughs.
From the perspective of the pattern of China’s CNC machine tool industry, the regional characteristics of the development of CNC machine tools in China are very obvious, and the obvious regional characteristics reflect the uneven development of CNC machine tools in China. For example, in Zhejiang, Shandong, Beijing, Hebei, and Sichuan regions, CNC machine tools have formed a relatively complete industrial system. On the one hand, these places have a relatively fast economic development speed and a high level of openness to the outside world, which is conducive to introducing advanced foreign technologies. On the other hand, it is because these regions have a wide market radiation, such as Sichuan, whose economic level is obviously not as good as the eastern coastal areas. However, in the southwest region, the market for Sichuan CNC machine tools is vast, and with the support of the country, its development is also relatively fast. However, in some old industrial production bases, the development of CNC machine tools is relatively slow.
In addition to uneven distribution, China’s CNC machine tools mainly consist of mid to low end products, while high-end CNC machine tools mainly rely on imports. According to Liu Baicheng, an academician of the CAE Member, “large but not strong” is the reality of China’s manufacturing industry. Taking CNC machine tools as an example, China has a large production of mid to low end CNC machine tools, but 80% of high-end CNC machine tools are imported. The proportion of imported equipment in the automotive industry exceeds 40%.
In recent years, the research on the foundation and common technologies of machine tool manufacturing has been continuously strengthened, and product development and technology research have been promoted synchronously. The maturity of key technologies such as reliability design and performance testing technology for machine tool products, and multi axis linkage machining technology has been greatly improved. The research results of digital design technology have been practically applied in the design of high-precision CNC coordinate boring machines, vertical machining centers, and other products; The software and hardware systems of real-time dynamic comprehensive compensation for multiple errors and error compensation for embedded CNC systems have been demonstrated and applied in multiple enterprises and products, resulting in a significant improvement in the accuracy of CNC machine tools.
