精(jing)(jing)密(mi)加(jia)(jia)(jia)工(gong)(gong)(gong)的(de)宗旨是為了實現加(jia)(jia)(jia)工(gong)(gong)(gong)極限。 隨著時間(jian)的(de)推移，隨著科學(xue)技術的(de)發(fa)展，這(zhe)一局限性也在改變，需要長期的(de)摸(mo)索和研究。 因此(ci)，如(ru)何堅(jian)持“進化加(jia)(jia)(jia)工(gong)(gong)(gong)原則”，通過使用低(di)于加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)(jing)度的(de)機(ji)(ji)械(xie)設備，利用先進的(de)工(gong)(gong)(gong)藝技術、計(ji)算機(ji)(ji)伺(si)服、特殊的(de)測量工(gong)(gong)(gong)具等，直(zhi)接間(jian)接滿足生產(chan)需要，直(zhi)接影響(xiang)精(jing)(jing)密(mi)加(jia)(jia)(jia)工(gong)(gong)(gong)或(huo)超(chao)精(jing)(jing)密(mi)加(jia)(jia)(jia)工(gong)(gong)(gong)零件(jian)的(de)整體質量。 顯然，加(jia)(jia)(jia)工(gong)(gong)(gong)機(ji)(ji)理是加(jia)(jia)(jia)工(gong)(gong)(gong)方式(shi)的(de)根本，是超(chao)精(jing)(jing)密(mi)加(jia)(jia)(jia)工(gong)(gong)(gong)技術和理論創(chuang)新發(fa)展的(de)關鍵(jian)，對零件(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)整體效果起著重要作用。隨著工(gong)(gong)(gong)業(ye)產(chan)業(ye)的(de)發(fa)展，新技術、新設備不斷創(chuang)新，機(ji)(ji)械(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)(jing)度水平大(da)幅提高。
