Abstract
With the fact that the wide impact of rise and abroad machinery finish machining over our country machinery manufacturing industry , tradition type machine tool that machinery parts accuracy demands now already have no way to satisfy modern manufacturing industry's, accuracy demands. Numerical control machine tool creation brings unparalleled innovation to unparalleled innovation world machinery manufacturing industry but beyond doubt with popularizing , whose treating accuracy , efficiency , complicated curved surface treating etc., is that are what the tradition machine tool has no way to comparison. Our country numerical control starting has been later , has been several tens years less compared with the developed countries such as Germany , USA, still not complete independent intellectual property right of in the homeland numerical control now, top grade numerical control system is dependent on entrance basically.
That our country maintains debugging aspect in numerical control is that talented person shortage , experience are deficient more , leads to a lot of top grade of in the homeland numerical control machine tool need to engage abroad expert keeping a debugging in repair. I am lucky to enter the machine tool manufacturer , the job having contacted a lot of home and abroad numerical control machine tool and system for 7 years,if Siemens, sends out that section , central China , Jien emperor etc.The main body of a book set off from concrete practice , contain content such as system , drive , electric motor , circuit completely, experience accumulation , fault analysis may be numerical control operation, be maintained , the reference data debugging in popular and easy-to-understand language in attaching importance to ordinary time more combining with theory knowledge simultaneous.
Keywords: Numerical control system , the servo drive , step-by-step drives , fault analysis removes
