【正文】 orld , estimate roughly as follows about the numerical control engineering level of our country and industrialization level. the engineering level, in probably backward 10 1 years with the advanced level in foreign countries, it is bigger in highquality precision and sophisticated technology. the industrialization level, the market share is low, the variety coverage rate is low, have not formed the largescale production yet。 Appearance quality is relatively poor。 Not setting up one39。s own brand effect yet in domestic numerical control system, users have insufficient confidence. the ability of sustainable development, to petition numerical control research and development of technology, engineered ability weaker。 The research , formulation that relevant standards are normal lags behind. It is analyzed that the main reason for having disparity described above has the following several respect. the respect. Know to domestic numerical control industry process arduousness , plexity and longterm characteristic insufficiently。 It is not enough to analyze to technological application level and ability of numerical control of our country. . Pay close attention to numerical control industrialization many in the issue , consider numerical control industrialization little in the issue synthetically in terms of the systematic one , industry chain in terms of technology。39。39。 Secondly seen from security of national defence, the western developed country has classified all the highgrade , precision and advanced numerical control products as the strategic materials of the country, realize embargo and restriction to our country, Toshiba incident and Cox Report is the best illustration. Development tactics Proceed from the angles of the fundamental realities of the country of our country, regard the strategic demand of the country and market demand of the national economy as the direction, regard improving our country and making the prehensive petitive power of equipping industry and industrialization level as the goal, use the systematic method , be able to choose the support technology that the initial our country makes the key technology upgraded in development of equipping industry and supports the development of industrialization in 21st century of leading factor, the ability to supply the necessary technology realizes making the jump type development of the equipping industry as the content of research and development. Emphasize market demand is a direction, take terminal products of numerical control as the core , with the plete machine (Such as the numerical control lathe having a large capacity and a wide range, milling machine , high speed high precise highperformance numerical control lathe , model digitized machinery , key industry key equipment ,etc. ) drive numerical control development of industry. Solve the numerical control system and relevant functions part especially The dependability in (digitized servo system and electrical machinery , electric main shaft system of high speed and new attachment that equip ,etc. ) and production scale question. There are no products without high dependability of scale 。 Certainly, it is difficult finally to have the day to hold up head that there is no Chinese numerical control equipment of scale . In equipping researching and developing highgrade , precision and advancedly , should emphasize the production, learning and research and close bination of end user, regard obtaining, using, selling as the goal, tackle key problems according to the national will, in order to solve the needing badly of the country. The technology of numerical control, emphasized innovation, put emphasis on researching and developing technology and products with independent intellectual property right before the petition, establish the foundation for the numerical control industry of our country , sustainable development of the equipment manufacture and even the whole manufacturing industry.
