Faster imports of machine tool products

Imports of 20.3 billion U.S. dollars, an increase of 29% over the same period last year. As a result of changes in the international machine tool marketing strategy, high-tech as the guide, high-tech armed low-priced mid-range machine tool products quickly occupy the Chinese machine tool market, posing serious challenges to China's domestic machine tool companies. Shen Xiyou, chairman of Shenyang Machine Tool Group, said.

In the machine tool industry, CNC machines generally use the number of axes as the standard, three-axis or lower-level low-grade, three-to-five-axis high-grade, and five-axis or higher-grade. For industry, the distinction between radical and modern production equipment is marked by radical machine tools and CNC machine tools, which has become the industry consensus. Machine bed sheet machine intelligent and automated that CNC machine tools is the direction of the machine tool industry, its high precision, high-detailed, high-speed, flexible, intelligent, modern industrial signs. 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 ​​the country's machine tool companies. The reporter interviewed three companies, namely Shenyang Machine Tool Group Co., Ltd., Dalian Machine Tool Group Co., Ltd., and Qizhong CNC Equipment Co., Ltd., in Northeast China Machine Tool Co., Ltd. They learned that there is a major lack of machine tool industry, including accuracy, stability, and reliability. For example, five-axis linkage CNC machine tools foreign products continuous 1500 hours without failure, made about 1000 hours, a difference of 1/3 of the two, the machine tool's composite performance varies greatly. 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 the European control technology, the core technology in the core technology, and it is strictly prohibited in Europe. The five-axis 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 differences in the numerical control system. 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. Fourth, the gap between other key components.

Jiang Huaisheng, vice president of Dalian Machine Tool Co., Ltd., said that Dalian machine tools can reach 95% of the international advanced level, but the remaining 5% is not a company or even an industry can include steel raw materials, regulatory parts, screws, nuts, etc., and need to upgrade the national industry. The overall level. In addition, the process, testing and other aspects are currently not up to the world advanced level.
