精密機械加工的優勢 現市(shi)場(chang)上無削的工藝(yi)同精(jing)密機(ji)械加工的(de)(de)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)相比較，精密機(ji)械(xie)加工(gong)(gong)(gong)(gong)(gong)(gong)有很(hen)大(da)的(de)(de)優(you)點，不但材(cai)(cai)料切除(chu)率很(hen)高，經濟性也很(hen)好。市場上并不常見的(de)(de)激光等(deng)離子的(de)(de)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)，與精密機(ji)械(xie)加工(gong)(gong)(gong)(gong)(gong)(gong)相比，等(deng)離子加工(gong)(gong)(gong)(gong)(gong)(gong)大(da)能量情(qing)況下能達到高材(cai)(cai)料的(de)(de)切除(chu)，并且加工(gong)(gong)(gong)(gong)(gong)(gong)出來的(de)(de)工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)精度與尺寸是否合(he)適(shi)也存(cun)在問題(ti)，而剛開始提出的(de)(de)那種無 削加工(gong)(gong)(gong)(gong)(gong)(gong)，比較是很(hen)很(hen)大(da)批量工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)的(de)(de)生(sheng)產，要(yao)(yao)想獲得工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)的(de)(de)合(he)格，后續(xu)還要(yao)(yao)進行加工(gong)(gong)(gong)(gong)(gong)(gong)切削。如(ru)此看來要(yao)(yao)想工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)得到較高的(de)(de)精度只有精密機(ji)械(xie)加工(gong)(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)比較合(he)適(shi)。現在精密(mi)機械(xie)加(jia)工廣泛(fan)應(ying)用，小批量生產的趨(qu)勢(shi)化更(geng)加促(cu)進了精密機(ji)械加工的發展，i對工件的(de)(de)(de)尺寸，精(jing)度要求(qiu)不(bu)斷提高(gao)的(de)(de)(de)情況下，也為精(jing)密(mi)機械加(jia)工拓展了更廣的(de)(de)(de)天地。車削加(jia)工時(shi)使用車床必然工序，除此(ci)以外，鉆(zhan)削，磨等更精(jing)細的(de)(de)(de)加(jia)工都能在同一(yi)個(ge)機床上實(shi)現(xian)。精(jing)密(mi)機械加(jia)工并不(bu)是一(yi)件容易的(de)(de)(de)加(jia)工技術，受很多因素(su)影響(xiang)，也有(you)(you)很大的(de)(de)(de)涉(she)及面，有(you)(you)很大強度的(de)(de)(de)投資，產品有(you)(you)極(ji)強的(de)(de)(de)個(ge)性，這些足以成(cheng)為影響(xiang)精(jing)密(mi)機械加(jia)工的(de)(de)(de)因素(su)。
