The overall level of manufacturing process of heavy machine tools in China is still insufficient in comparison with foreign

China's heavy-duty machine tool industry has been in recent years, technological innovation, production capacity and the level of product technology have made great progress, but compared with foreign products, there is a great lack of. According to the China Machine Tool | standing proudly network learned the biggest difference is the technical level and the operating speed of the core runtime components, products maintain the accuracy of machine reliability, as well as the overall level of machine tool manufacturing process and quality of several.

The reliability of CNC machine tools is a key indicator of the high-grade heavy-duty machine quality. Currently, the average time between failures of domestic CNC heavy machine tools is not higher than 300 hours, while the high-end imported heavy machine tools mean time between failures of more than 2000 hours (the international standard of 800 hours), and accuracy of maintaining high. The time between failures (MTBF) is defined as "products within the specified time under specified conditions and the ability to perform a required function." Emphasis on the actual effect of the product on-site use or running. Therefore, the time between failures of CNC machine tools to ively reflect the real situation between failures of the products in the production process, which is the majority of machine tool users really care about the product quality attributes. Obviously, the level of reliability of domestic CNC heavy machine tools with foreign significantly lower, and seriously affect the competitiveness and market share of the domestic CNC heavy machine tools.

Geometric precision and accuracy made CNC machine tools during the testing, can reach higher than the design standard, but the bulk product has failed to achieve the the station high precision requirements. Foreign enterprises through state-of-the-art manufacturing process control, CNC machine tools, high-precision produced in bulk. Made CNC machine tools to commodities is still some distance from the sample (exhibits).

Heavy machine tool manufacturers in China still lack the ability of independent innovation and fundamental research. Applied to today's latest technology and new technology developed in a modular form of new products, which is the trend of development of China's heavy-duty machine tools.

New product development work should pay particular attention to: The first in-depth study the user industry process characteristics and requirements, combined with the technological characteristics of the development of a high level of processing equipment. Second, focus on the basic theory research, strengthen key components of the experimental research, to strengthen the new product, the first sets the machine running test and after-sale tracking service. Rectify and improve the work of new products, and reduce the exhibits to the goods and the time of the formation of industry.
