The development of China's machine tool industry is obviously problematic

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.

Northeast China is the most concentrated and strongest region in China's machine tool companies. The reporter learned from the three major enterprises of the Shenyang Machine Tool Group Corporation, Dalian Machine Tool Group Company, and Qizhong CNC Equipment Co., Ltd., which are representative of Northeastern Machine Tool Co., Ltd., that the major 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 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. 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., need to improve the overall level of national industry. In addition, the process, testing and other aspects are currently not up to the world advanced level.
