The Gap Between Homemade CNC Machine Tools And Imported Machine Tools

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. After several generations of hard work in the Chinese machine tool industry, from 1600 production of simple belt machine tools in 1949 to machine tool production reached 617,000 units in 2008, becoming the third largest machine tool producer in the world, more than 60 years of development, China's machine tool industry The earth-shaking changes, but compared with foreign high-end machine tools, there are still some gaps, as long as reflected in the following three aspects; First, the accuracy, stability, reliability and other gaps. For example, five-axis linkage CNC machine tools foreign products continuous 1500H no failure, made about 1000H, a difference of 1/3. Second, the gap between CNC systems. The numerical control 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 systems. The Liebherr CNC system's 16 software packages cost close to the cost 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.
