零件(jian)(jian)(jian)加(jia)(jia)工(gong)(gong)表(biao)面(mian)(mian)上，不應有劃痕、擦傷等損傷零件(jian)(jian)(jian)表(biao)面(mian)(mian)的缺陷(xian)，加(jia)(jia)工(gong)(gong)的螺紋表(biao)面(mian)(mian)不允許有黑(hei)皮、磕碰、亂扣和(he)毛刺等缺陷(xian)。所有需(xu)要進(jin)(jin)行(xing)(xing)涂裝的鋼鐵(tie)制件(jian)(jian)(jian)表(biao)面(mian)(mian)在涂漆(qi)前，機(ji)械加(jia)(jia)工(gong)(gong)價格表(biao)，必須將鐵(tie)銹(xiu)、氧化皮、油脂、灰塵、泥土、鹽(yan)和(he)污物等除去。在進(jin)(jin)行(xing)(xing)機(ji)械加(jia)(jia)工(gong)(gong)的時候，學會對零部件(jian)(jian)(jian)的精度進(jin)(jin)行(xing)(xing)控(kong)(kong)制是很(hen)有必要的一件(jian)(jian)(jian)事情，因為只有精度得到(dao)控(kong)(kong)制以后，才能夠讓加(jia)(jia)工(gong)(gong)出來的零部件(jian)(jian)(jian)更能夠滿足精密需(xu)求(qiu)。機(ji)械加(jia)(jia)工(gong)(gong)是通過機(ji)械設備對工(gong)(gong)件(jian)(jian)(jian)的外形尺寸(cun)或性能進(jin)(jin)行(xing)(xing)改變的加(jia)(jia)工(gong)(gong)過程(cheng)，機(ji)械加(jia)(jia)工(gong)(gong)對現(xian)代工(gong)(gong)業生產起(qi)到(dao)了(le)非常重要的作用。

對零件進行這一工(gong)(gong)序呢，一般通(tong)過精密車削，研磨等操(cao)作，常(chang)常(chang)能(neng)讓(rang)那些有色金屬材料(liao)制(zhi)作的(de)(de)(de)零件表(biao)面形成一定的(de)(de)(de)光(guang)潔表(biao)面，比如我們常(chang)說的(de)(de)(de)鏡面效果。機(ji)(ji)械(xie)加(jia)工(gong)(gong)的(de)(de)(de)優勢：機(ji)(ji)械(xie)加(jia)工(gong)(gong)不需要開模，且(qie)自由度高；機(ji)(ji)械(xie)加(jia)工(gong)(gong)的(de)(de)(de)精度非常(chang)高，有利于(yu)提(ti)高工(gong)(gong)件質(zhi)量；機(ji)(ji)械(xie)加(jia)工(gong)(gong)的(de)(de)(de)，有利于(yu)提(ti)高產(chan)量。機(ji)(ji)械(xie)加(jia)工(gong)(gong)性能(neng)不僅(jin)和企業(ye)的(de)(de)(de)利益相(xiang)關，還(huan)和安(an)全性相(xiang)關，在給(gei)企業(ye)帶來經濟(ji)效益的(de)(de)(de)同時(shi)，還(huan)可以有效降低安(an)全事故發(fa)生的(de)(de)(de)概率。

對零件(jian)進(jin)行這(zhe)一工(gong)(gong)序呢，安徽機(ji)(ji)(ji)械(xie)加工(gong)(gong)，一般通過(guo)精(jing)密車削，研磨等操作(zuo)，常常能讓那些(xie)有色金屬材料制作(zuo)的(de)零件(jian)表面形成一定(ding)(ding)(ding)的(de)光潔表面，精(jing)密機(ji)(ji)(ji)械(xie)加工(gong)(gong)，比(bi)如我們常說(shuo)的(de)鏡(jing)面效(xiao)果。機(ji)(ji)(ji)械(xie)零件(jian)加工(gong)(gong)上的(de)點、線(xian)、面的(de)實際位(wei)置與理想(xiang)位(wei)置的(de)符(fu)合程(cheng)度(du)(du)(du)。評定(ding)(ding)(ding)位(wei)置精(jing)度(du)(du)(du)的(de)項(xiang)目按GB/T1182—1996規定(ding)(ding)(ding)，有平行度(du)(du)(du)、垂直度(du)(du)(du)、傾斜度(du)(du)(du)、同軸度(du)(du)(du)、對稱度(du)(du)(du)、位(wei)置度(du)(du)(du)、圓跳動(dong)和全跳動(dong)等8項(xiang)。位(wei)置精(jing)度(du)(du)(du)是(shi)用(yong)位(wei)置誤差(cha)來(lai)控(kong)制的(de)，各(ge)項(xiang)目的(de)位(wei)置公差(cha)分為(wei)12個精(jing)度(du)(du)(du)等級。機(ji)(ji)(ji)械(xie)零件(jian)加工(gong)(gong)變(bian)(bian)形的(de)改進(jin)措(cuo)施：在(zai)實際的(de)機(ji)(ji)(ji)械(xie)零件(jian)加工(gong)(gong)中，附近機(ji)(ji)(ji)械(xie)加工(gong)(gong)廠，導致零件(jian)變(bian)(bian)形的(de)因素很(hen)多。為(wei)了從根本上解決這(zhe)些(xie)變(bian)(bian)形問題，操作(zuo)人(ren)員(yuan)需要在(zai)實際工(gong)(gong)作(zuo)中認真探索這(zhe)些(xie)因素，并結合工(gong)(gong)作(zuo)精(jing)要，制定(ding)(ding)(ding)改進(jin)措(cuo)施。
