精(jing)(jing)密加(jia)(jia)工(gong)(gong)(gong)的(de)(de)(de)宗旨是(shi)為了實現加(jia)(jia)工(gong)(gong)(gong)極限。 隨(sui)著時間的(de)(de)(de)推移，隨(sui)著科(ke)學技術的(de)(de)(de)發展(zhan)(zhan)，這一(yi)局(ju)限性也在改變，需要(yao)長期的(de)(de)(de)摸索和研究。 因此，如何堅持“進化(hua)加(jia)(jia)工(gong)(gong)(gong)原則(ze)”，通過使(shi)用低于加(jia)(jia)工(gong)(gong)(gong)精(jing)(jing)度的(de)(de)(de)機械設備(bei)，利用先進的(de)(de)(de)工(gong)(gong)(gong)藝(yi)技術、計算機伺服、特殊的(de)(de)(de)測量(liang)(liang)工(gong)(gong)(gong)具等，直接(jie)間接(jie)滿足(zu)生產需要(yao)，直接(jie)影響精(jing)(jing)密加(jia)(jia)工(gong)(gong)(gong)或(huo)超精(jing)(jing)密加(jia)(jia)工(gong)(gong)(gong)零件的(de)(de)(de)整體(ti)質量(liang)(liang)。 顯然，加(jia)(jia)工(gong)(gong)(gong)機理(li)是(shi)加(jia)(jia)工(gong)(gong)(gong)方式的(de)(de)(de)根本，是(shi)超精(jing)(jing)密加(jia)(jia)工(gong)(gong)(gong)技術和理(li)論創新發展(zhan)(zhan)的(de)(de)(de)關鍵(jian)，對(dui)零件加(jia)(jia)工(gong)(gong)(gong)整體(ti)效果起著重要(yao)作用。隨(sui)著工(gong)(gong)(gong)業(ye)(ye)產業(ye)(ye)的(de)(de)(de)發展(zhan)(zhan)，新技術、新設備(bei)不(bu)斷(duan)創新，機械加(jia)(jia)工(gong)(gong)(gong)精(jing)(jing)度水平大(da)幅提高。
