There is a gap between China's CNC system and the international market

Industry statistics from the China Machine Tool Association in 2011 showed that China's imports of machine tool products grew rapidly, with imports of US$20.3 billion, a year-on-year increase of 29%. Imports are all high-grade machine tools.

“Because of the changes in international machine tool marketing strategies, the use of high technology as a precursor, and the use of high-tech armed low-priced mid-range machine tool products to quickly occupy the Chinese machine tool market, poses a serious challenge to China's domestic machine tool companies.” Guan Xiyou, chairman of Shenyang Machine Tool Group, said.

In the machine tool industry, numerical control machine tools generally use the number of axes as the standard, the three-axis or lower axis is the low-grade, the three- to five-axis are medium-to-high grade, and the five-axis or higher axis is the high grade. For industry, the distinction between traditional and modern production equipment is the traditional machine tools and CNC machine tools, which has become the industry consensus. Machine bed machine intelligent and automation that CNC machine tools is the direction of the machine tool industry, its high precision, high fineness, high speed, flexibility, intelligence, is a sign of modern industry. The modern equipment industry is developing in the direction of extreme manufacturing. One is more and more tall, the second is more and more small, the third is more and more complex, and the production process is highly integrated.

Looking at the level of equipment manufacturing industry in the northeast, the level of machine tools also looks at the northeast, and the northeast is the most concentrated and most powerful area of ​​China's machine tool companies. The reporter learned from interviews with three major companies, namely Shenyang Machine Tool Group Co., Ltd., Dalian Machine Tool Group Co., and Qizhong CNC Equipment Co., Ltd., that the main deficiencies in the machine tool industry are:

First, the accuracy, stability, reliability, and other gaps. For example, five-axis linkage CNC machine tools foreign products continuous 1500 hours without failure, made about 1000 hours, a difference of 1/3.

Second, the compounding performance of machine tools is quite different. At present, the five-axis linkage machining center is mostly used in aerospace and nuclear power, and the price of a single unit reaches four to five million yuan. Five-axis linkage CNC is a European control technology and a core technology in core technology. Europe is strictly prohibited from leaking. The five axes must be guaranteed not to be used for military purposes. Shenyang Machine Tool, Dalian Machine Tool, Qizhong CNC can do three axes, five axes can also be done, but there is a certain gap between performance and imported products. The high-end machine tools used by domestic companies, aerospace, and other key research institutes are all basically imported.

Third, the gap between CNC systems. CNC system is the core of CNC machine tools. Germany's Siemens, Liebherr and Japan's Mazak and Farak have mastered the highest level of CNC system. The Liebherr CNC system has 16 software packages whose prices are close to the price of the mother machine. The software and the parent machine together Selling, not selling separately, the software profit is very high. At present, the CNC systems used by domestic machine tool companies in the high-end machine tools are basically imported.

Third, the gap between other key components. Jiang Huaisheng, Vice President of Dalian Machine Tool Co., Ltd. stated that Dalian's machine tools can reach 95% of the international advanced level, but the remaining 5% is not a company or even an industry can do, including steel raw materials, standard parts, screws, nuts, etc. Improve the overall level of the country’s industry. In addition, the process, testing and other aspects are currently not up to the world advanced level.
