Introduction: Numerical control punching machine is the abbreviation of digital control punching machine, it is a kind of automation machine tool of programme controll system. This control system can be located in manage to have the program that control codes or other sign instruction sets logically, and its coding, make punching machine movement machines a spare parts thereby. The punching machine in be being operated actually wears away easily also, below is brief introduce to wear away reason and examination of fixed position precision. In production of industry of 　 of 　 of reason of tatty of punching machine mould, in use of mould of numerical control punching machine is incidental to core the wear extent of buy of each side position differs, some parts have bigger nick, wear away faster, this kind of circumstance is in fine on narrow long square mould particularly apparent. So cause grind a tatty what is main reason? 1) the machine tool turns to the tower is designed or machine precision inadequacy, the mould that basically is fluctuation dial is installed bad to neuter. 2) the design of punching machine mould or treatment precision cannot satisfy a requirement. 3) the guide-post bushing precision of mould punch is insufficient. Punch wears away too fast main reason: 1) mould clearance slants small, total space of general proposal mould is the 20% ～ with material thick board 　 of 　 of 25% 　 　 2) punch temperature is exorbitant, because same pattern is successive,basically be long punch causes drift overheat. 3) what punch-die provides is bad to neuter, include a model with the mould oriented component is reached turn the tower sets the reason such as a precision inadequacy to create a pattern bad to neuter. 4) mould blade grinds a method undeserved, cause mould anneal, wear away aggravate. The fixed position precision that numerical control punching machine locates precision checks punching machine of 　 　 numerical control has its special sense. It is to show measures numerical control develops each motion component to control the precision that next motion can achieve in numerical control device. Accordingly, according to the numerical value of the fixed position precision of actual measurement, can judge the best work that in giving this numerical control to develop automatic treatment, can obtain to machine precision, does fixed position precision basically detect does content have: ? . ? ) precision of sharp movement fixed position; (2) sharp movement repeats fixed position precision; (3) of origin of machinery of sharp movement rod return precision; (4) of momentum of sharp movement arrow determine; (5) the fixed position precision that circumgyrate moves; (6) answer what have a change of luck moves to repeat fixed position precision; (7) of rotor origin return precision; (8) of the arrowy momentum that circumgyrate moves determine.
