精(jing)密(mi)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)的(de)(de)宗旨是為了(le)實現(xian)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)極限。 隨著(zhu)時間的(de)(de)推(tui)移(yi)，隨著(zhu)科(ke)學技(ji)(ji)(ji)術(shu)的(de)(de)發展，這一(yi)局限性也在改變，需要長(chang)期的(de)(de)摸索和研究。 因此，如何堅持“進(jin)化加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)原則”，通過使用低于加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)度的(de)(de)機(ji)(ji)(ji)械(xie)設(she)備，利用先(xian)進(jin)的(de)(de)工(gong)(gong)(gong)(gong)藝(yi)技(ji)(ji)(ji)術(shu)、計(ji)算機(ji)(ji)(ji)伺(si)服(fu)、特殊的(de)(de)測量(liang)(liang)工(gong)(gong)(gong)(gong)具等，直(zhi)接(jie)間接(jie)滿足生(sheng)產需要，直(zhi)接(jie)影響精(jing)密(mi)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)或(huo)超精(jing)密(mi)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)零(ling)件(jian)的(de)(de)整體質(zhi)量(liang)(liang)。 顯然，加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)機(ji)(ji)(ji)理是加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)方(fang)式的(de)(de)根本，是超精(jing)密(mi)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)技(ji)(ji)(ji)術(shu)和理論(lun)創新發展的(de)(de)關鍵(jian)，對零(ling)件(jian)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)整體效果起著(zhu)重要作用。隨著(zhu)工(gong)(gong)(gong)(gong)業產業的(de)(de)發展，新技(ji)(ji)(ji)術(shu)、新設(she)備不斷創新，機(ji)(ji)(ji)械(xie)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)度水平大幅提(ti)高。
