在具體的(de)(de)(de)精(jing)密(mi)機(ji)械(xie)零(ling)(ling)件(jian)加工中,零(ling)(ling)件(jian)的(de)(de)(de)規格(ge)與零(ling)(ling)件(jian)的(de)(de)(de)設計緊(jin)密(mi)相合,在實際的(de)(de)(de)操(cao)作中-一些零(ling)(ling)件(jian)的(de)(de)(de)加工需要對精(jing)密(mi)機(ji)械(xie)零(ling)(ling)件(jian)進(jin)行反復的(de)(de)(de)切(qie)割操(cao)作,在操(cao)作過(guo)程中由于刀具的(de)(de)(de)長時(shi)間反復切(qie)割使(shi)用會有一定(ding)的(de)(de)(de)熱(re)(re)量(liang) ,這(zhe)種熱(re)(re)量(liang)會使(shi)零(ling)(ling)件(jian)產生熱(re)(re)變形,導致零(ling)(ling)件(jian)的(de)(de)(de)精(jing)準度下降(jiang)。

機(ji)(ji)(ji)械(xie)(xie)加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝對零(ling)件(jian)加(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)(de)(de)內在(zai)(zai)因素影響。在(zai)(zai)實(shi)際的(de)(de)(de)(de)(de)機(ji)(ji)(ji)械(xie)(xie)加(jia)工(gong)(gong)(gong)(gong)中(zhong)影響零(ling)件(jian)加(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)(de)(de)內部因素也(ye)需要被重視起來。首先，精(jing)密機(ji)(ji)(ji)械(xie)(xie)加(jia)工(gong)(gong)(gong)(gong)系(xi)統在(zai)(zai)長期的(de)(de)(de)(de)(de)使(shi)用中(zhong)會(hui)產生一一些(xie)問題(ti) ,機(ji)(ji)(ji)械(xie)(xie)系(xi)統在(zai)(zai)長期的(de)(de)(de)(de)(de)高強度作(zuo)(zuo)業(ye)下(xia)產生磨(mo)損,導致機(ji)(ji)(ji)床整體出(chu)現誤差。機(ji)(ji)(ji)床上的(de)(de)(de)(de)(de)重點使(shi)用工(gong)(gong)(gong)(gong)具(ju)(ju)出(chu)現磨(mo)損如(ru)刀具(ju)(ju)、夾具(ju)(ju)。這些(xie)工(gong)(gong)(gong)(gong)具(ju)(ju)的(de)(de)(de)(de)(de)磨(mo)損會(hui)導致機(ji)(ji)(ji)械(xie)(xie)加(jia)工(gong)(gong)(gong)(gong)中(zhong)誤差的(de)(de)(de)(de)(de)長生。機(ji)(ji)(ji)械(xie)(xie)安裝使(shi)用中(zhong)因為安裝者在(zai)(zai)具(ju)(ju)體操作(zuo)(zuo)中(zhong)的(de)(de)(de)(de)(de)失(shi)誤也(ye)會(hui)使(shi)機(ji)(ji)(ji)械(xie)(xie)系(xi)統的(de)(de)(de)(de)(de)具(ju)(ju)體加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)作(zuo)(zuo)產生失(shi)誤，導致零(ling)件(jian)精(jing)度 下(xia)降。

在實(shi)際的(de)精密機(ji)械(xie)加工(gong)中,將影響(xiang)零件(jian)加工(gong)因素重視起來,首先,重視機(ji)械(xie)加工(gong)系統在長期的(de)使用中產生的(de)問題,對機(ji)械(xie)系統進(jin)行(xing)(xing)定期的(de)、正規的(de)保養,對易(yi)磨(mo)損(sun)的(de)零部件(jian)刀片人、夾具(ju)等進(jin)行(xing)(xing)定期的(de)檢測(ce),如果磨(mo)損(sun)嚴(yan)重就對該部件(jian)進(jin)行(xing)(xing)及時更換(huan),保證機(ji)械(xie)零件(jian)加工(gong)的(de)精度。
