tionability the numerical control serial production factory. Lanzhouelectrical machinery plant, Central China numerical control and so onone batch of servosystems and servo electrical machinery productionfactory as well as Beijing first machine tool factory, Jinan firstmachine tool factory and so on certain numerical control main engineproduction factories. These produced the plant site book to form ourcountry numerical control industry base. C. Has established a numerical control research, the development,managerial talent39。 s basic troop. Although has made the considerable progress in the numerical controltechnology research development as well as the industry aspect, but wealso must soberly realize, our country high end numerical controltechnology research development, in particular also has a biggerdisparity in the industry aspect technical level present situation andthe our country realistic demand. Although from longitudinal lookedour country the development speed is very quick, but crosswisepared to (with overseas contrast) not only the technical level hasthe disparity, also has the disparity in certain aspect developmentspeeds, namely some precise and advanced numerical control equipmentstechnical level disparities have the expanded tendency. Frominternational looked that, is approximately as follows to our countrynumerical control technical level and the industry level estimate. A. In the technical level, probably falls behind with the overseasadvanced level for 10 ~ 15 years, in precise and advanced technicalaspect then is bigger. B. In industry level, market share low, variety Cover is small,but also has not formed the scale production。 The function partspecialization production level and the plete set ability arelower。 Outward appearance quality Relative。 The reliability is nothigh, the mercialized degree is insufficient。 The domesticallyproduced numerical control system not yet establishes own brandeffect, the user confidence is insufficient. C. In the sustainable development ability, to the petition beforethe numerical control technology research development, the projectability is weaker。 Numerical control technology application domaindevelopment dynamics is not strong。 Correlation standard standardresearch, formulation lag. The analysis existence above disparity main reason has followingseveral aspects. A. Knows the aspect. To domestically produced numerical controlindustry advancement arduous, plexity and long term characteristicunderstanding insufficiency。 To the market not standard, overseasblocks Canada to strangle, the system and so on the difficultunderestimate。 Is insufficient to our country numerical controltechnology application level and the ability analysis. B. System aspect. From technical angle attention numerical controlindustry question time many, from system, industrial chain anglesynthesis consideration numerical control industry question time arefew。 Has not established the integrity high grade necessary strutsystem and so on system, consummation training, service work. C. Machinemade aspect. Not the good mechanism creates brain drain,also has restricted technical and the technical route innovation, theproduct innovation, also has restricted the plan effectiveimplementation, often plans the ideal, the implementation difficulty. D. Technical aspect. The enterprise independently innovates in thetechnical aspect the ability not to be strong, the core technologyproject ability is not strong. Engine bed standard backward, levellower, the numerical control system new standard research isinsufficient. Third, to our country numerical control technology and industrydevelopment strategic ponder strategic considerations Our country makes the great nation front end, must accept inthe world industry shift but is not the rear end shi。
