China's high-end CNC machine tool technology development in recent years, great progress has been made, many breakthroughs in core technologies is the enhancement ofChina's machine tool industry in the international market competitiveness. But undeniable, the domestic machine tool industry with international advanced level photograph is compared, still put in bigger difference.

Some key technologies, such as: high speed and high precision motion control technology, dynamic compensation technology, multi axis linkage and composite processing technology, intelligent technology, high precision direct drive technology, reliability technology needs further breakthrough, some major technology from industrialization to still a paragraph of road engineering. Be badly in need of solving technical problems mainly have the following several aspects:

( 1) improve product reliability. Reliability is to improve product quality and production efficiency of the guarantee. The current domestic research and development of NC machine tools, mainly for high-grade, the pursuit of high speed, precision and multi axis linkage composite processing. Although many products in the functional, specifications have reached or even exceeded the international first-class enterprise in the same industry products, but the stability and reliability of products is still relatively poor. With the increase of composite function and intensive technology is introduced, the unreliable factor and hidden fault increase, the market has rate on the low side, weak competitiveness. Reliability of NC machine tool relates to the production of plant design, manufacture, assembly, test, and after sale service supply all internal departments, relates to fittings, parts suppliers, also relates to a machine tool user, this is a need for more joint efforts of Department of systems engineering.Enterpriseand even entire industry must promote the reliability of the product, to solve the product " the shape of God not as " problem, enhance product market competition ability.

( 2) heavy NC machine tool product quality, on level, should focus on resolving several key technologies: optimization design technology of typical kinematic pair; reliability design; reliability growth and reliability growth test technology; high speed spindle dynamic stiffness and bearing heat balance system and dynamic balancing of high speed feed; dynamic characteristics test, controlled, prospective acceleration stability control technology; automatic on-line measurement, error compensation technology of long-distance gapless transmission technology; technical problems.

( 3 ) to enhance the core parts of the transmission speed, accuracy, and the whole machine tool manufacturing technology level and quality. Through increased R & D efforts, process optimization methods, strengthening scientific research and experiment, improve the means of information, accelerate the upgrade of ways to enhance the level and quality of NC machine tool manufacturing.

( 4) the establishment of the enterprise as the main body, it is with the market oriented, produce learn to grind with the combination of R & D system, improve the industry's independent innovation ability. We should promote the industrialization base project; and university cooperation, with advanced technology to promote the production, in the production practice to consolidate academic, academic theory to promote technical innovation, foster a strong technical talent team; to market trends as the orientation, improve market suitable stress and share.
