精(jing)密(mi)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)宗旨是為了實現(xian)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)極限。 隨著時間(jian)的(de)(de)(de)推移，隨著科學技(ji)術(shu)的(de)(de)(de)發展，這一局限性也在(zai)改變，需要長期的(de)(de)(de)摸索(suo)和(he)(he)研究。 因此，如(ru)何堅持(chi)“進化加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)原(yuan)則”，通過使(shi)用低于加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)精(jing)度的(de)(de)(de)機(ji)(ji)(ji)械(xie)(xie)設備，利用先(xian)進的(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)藝技(ji)術(shu)、計算機(ji)(ji)(ji)伺(si)服、特殊的(de)(de)(de)測量(liang)工(gong)(gong)(gong)(gong)(gong)具等，直接(jie)間(jian)接(jie)滿(man)足生產需要，直接(jie)影響精(jing)密(mi)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)或超(chao)精(jing)密(mi)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)零件(jian)的(de)(de)(de)整(zheng)體質量(liang)。 顯然，加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)機(ji)(ji)(ji)理(li)是加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)方式的(de)(de)(de)根本，是超(chao)精(jing)密(mi)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)技(ji)術(shu)和(he)(he)理(li)論創(chuang)新(xin)發展的(de)(de)(de)關鍵，對零件(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)整(zheng)體效果起著重要作用。隨著工(gong)(gong)(gong)(gong)(gong)業產業的(de)(de)(de)發展，新(xin)技(ji)術(shu)、新(xin)設備不(bu)斷創(chuang)新(xin)，機(ji)(ji)(ji)械(xie)(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)精(jing)度水平大(da)幅提高(gao)。
