精密加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)(de)宗旨是為了(le)實現加(jia)(jia)工(gong)(gong)(gong)(gong)極限。 隨(sui)著(zhu)時間的(de)(de)(de)(de)推移(yi)，隨(sui)著(zhu)科學技(ji)(ji)術(shu)的(de)(de)(de)(de)發展(zhan)，這一局限性也在改(gai)變，需(xu)(xu)要長期的(de)(de)(de)(de)摸索和(he)研究。 因此，如何堅持(chi)“進化加(jia)(jia)工(gong)(gong)(gong)(gong)原則”，通(tong)過(guo)使用(yong)低于(yu)加(jia)(jia)工(gong)(gong)(gong)(gong)精度的(de)(de)(de)(de)機械(xie)設(she)備，利用(yong)先(xian)進的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)藝技(ji)(ji)術(shu)、計算機伺服、特殊的(de)(de)(de)(de)測量工(gong)(gong)(gong)(gong)具(ju)等，直接間接滿足(zu)生產需(xu)(xu)要，直接影響精密加(jia)(jia)工(gong)(gong)(gong)(gong)或超(chao)精密加(jia)(jia)工(gong)(gong)(gong)(gong)零(ling)件(jian)的(de)(de)(de)(de)整(zheng)體(ti)質量。 顯然(ran)，加(jia)(jia)工(gong)(gong)(gong)(gong)機理(li)是加(jia)(jia)工(gong)(gong)(gong)(gong)方(fang)式的(de)(de)(de)(de)根本，是超(chao)精密加(jia)(jia)工(gong)(gong)(gong)(gong)技(ji)(ji)術(shu)和(he)理(li)論創新(xin)發展(zhan)的(de)(de)(de)(de)關(guan)鍵，對零(ling)件(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)整(zheng)體(ti)效果起著(zhu)重要作用(yong)。隨(sui)著(zhu)工(gong)(gong)(gong)(gong)業產業的(de)(de)(de)(de)發展(zhan)，新(xin)技(ji)(ji)術(shu)、新(xin)設(she)備不斷創新(xin)，機械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)精度水平大幅提高。
