精(jing)密加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)宗旨是為了實現加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)極限(xian)。 隨(sui)著時間的(de)推移，隨(sui)著科學技術的(de)發(fa)展(zhan)，這一局限(xian)性(xing)也(ye)在改變，需(xu)要長期的(de)摸索和(he)研究(jiu)。 因此，如何堅持(chi)“進(jin)(jin)化(hua)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)原則”，通過使用低于加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)精(jing)度(du)的(de)機(ji)(ji)械設備，利用先進(jin)(jin)的(de)工(gong)(gong)(gong)(gong)(gong)藝技術、計算機(ji)(ji)伺(si)服(fu)、特殊(shu)的(de)測量(liang)工(gong)(gong)(gong)(gong)(gong)具等，直接(jie)間接(jie)滿足生產(chan)需(xu)要，直接(jie)影(ying)響精(jing)密加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)或超(chao)精(jing)密加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)零件的(de)整(zheng)(zheng)體(ti)質量(liang)。 顯然，加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)機(ji)(ji)理是加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)方式的(de)根(gen)本，是超(chao)精(jing)密加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)技術和(he)理論創(chuang)(chuang)新發(fa)展(zhan)的(de)關(guan)鍵，對零件加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)整(zheng)(zheng)體(ti)效果(guo)起著重要作用。隨(sui)著工(gong)(gong)(gong)(gong)(gong)業(ye)產(chan)業(ye)的(de)發(fa)展(zhan)，新技術、新設備不斷創(chuang)(chuang)新，機(ji)(ji)械加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)精(jing)度(du)水平大幅提高(gao)。
