【正文】 policy and the national attention, as well as the research and development of environment and international environment, our country numerical control technology research, development and the localization of products have made considerable progress.The third stage is in the national eight five and Nine Five of the late period, namely the implementation industrialization research, into the market petition stage.At this stage, China39。s domestic CNC equipment industry has made substantial progress. In the Nine Five stage, domestic CNC machine tool 39。s 50% share of the domestic market, with domestic NC system ( Universal ) also reached 10%.Looking at China39。s CNC technology development course of nearly 50 years, especially after the 4 5 years plan research, overall obtained the following results.（1）Lay the CNC technology development foundation, basic knowledge of modern NC technique. China has now mastered from the NC system, servo drive, NC machine, special machines and accessories based techniques, most of which technology has mercial development foundation, part of technology mercialization, industrialization.( 2) the initial formation of the industrial base of c. The research achievements and some technical modity on the basis of the establishment, such as CNC, aerospace has a production capacity of the NC system production plant.Lanzhou motor factory, and a number of servo system of CNC and servo motor production plant, Beijing first machine tool plant, Ji39。nan first machine tool plant of machine manufacturing plant. These factories basically formed our country numerical control industry base.( 3) the establishment of a CNC research, development, management personnel of the basic team. Although in the CNC technology research development and industrialization has made considerable progress, but we also should realise soberly, our highend CNC technology research and development, especially in the industrialization level of technical current situation and the reality of China39。s demand still have bigger difference.Although from a longitudinal look at our country develops very fast, but transverse than ( contrast with abroad ) not only technical level to have difference, in some aspects of development speed also has difference, . the number of sophisticated CNC equipment technical level difference has distensible tendency.From the international perspective, to our country numerical control technology and industrialization level is estimated as follows.(1) the level of technology, with foreign advanced level lags behind about 10 ~ 15 years, in the sophisticated technology is larger.( 2) industrialization level, the market is had rate is low, breed coverage, has formed the scale of production。 functional ponents of professional production level and plete sets of capacity is low。 the appearance quality is relatively poor。 the reliability is not high, lack of mercialization。 domestic CNC system has not been established their own brand, customer confidence.( 3) the ability of sustainable development, the petition before NC technology research and development, engineering ability is weaker。 CNC technical application field strength is not strong。 related standards, research, develop lag.Analysis of the existence of the gap between the main reason has the following several aspects.(1): understanding of CNC industrial process difficulty, plexity and longterm sex characteristic understanding insufficiency。 the market is not standardized, overseas blockade with strangulation, system difficult underestimate。 to our country numerical control technology application level and ability analysis is not enough.( 2) system : from a technical perspective on CNC industrialization problem when much, from the system, the point of view of industry chain integrated into the CNC industrialization problem when little。 not the establishment of a plete quality system, perfect training, service network support system.( 3) mechanisms: adverse mechanisms causing the loss of talented people, and restricted technology and technical route of innovation, product innovation, and restricts the effective implementation of the project, often the planning ideal, implementation difficulties.( 4) the technical aspects: enterprise technology independent innovation capability is not strong, the core technology of engineering ability is not strong. Machine tool standard is backward, level is low, the new standard is not enough research of CNC system.
