機(ji)(ji)(ji)(ji)械(xie)(xie)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)是一(yi)種用加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)機(ji)(ji)(ji)(ji)械(xie)(xie)對(dui)工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)的(de)外形尺(chi)寸或(huo)性能(neng)進行改變的(de)過(guo)(guo)程(cheng)。按(an)(an)被(bei)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)的(de)工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)處于的(de)溫度(du)狀(zhuang)態﹐分為(wei)冷加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)和熱加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)。精(jing)密(mi)零部件(jian)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)的(de)定(ding)義是，按(an)(an)步(bu)驟(zou)，機(ji)(ji)(ji)(ji)械(xie)(xie)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)廠，按(an)(an)工(gong)(gong)(gong)(gong)(gong)(gong)序完成各主要(yao)表(biao)面的(de)終(zhong)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)，機(ji)(ji)(ji)(ji)械(xie)(xie)精(jing)密(mi)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)，包括工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)平(ping)行度(du)，表(biao)面光潔度(du)，表(biao)面垂直度(du)，表(biao)面硬度(du)等等，使零件(jian)的(de)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)精(jing)度(du)和加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)表(biao)面質量達到(dao)圖(tu)樣規定(ding)的(de)要(yao)求的(de)過(guo)(guo)程(cheng)。機(ji)(ji)(ji)(ji)械(xie)(xie)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)是通過(guo)(guo)機(ji)(ji)(ji)(ji)械(xie)(xie)設(she)備對(dui)工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)的(de)外形尺(chi)寸或(huo)性能(neng)進行改變的(de)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)過(guo)(guo)程(cheng)，合肥機(ji)(ji)(ji)(ji)械(xie)(xie)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)，機(ji)(ji)(ji)(ji)械(xie)(xie)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)對(dui)現(xian)代工(gong)(gong)(gong)(gong)(gong)(gong)業生(sheng)產起到(dao)了非常重要(yao)的(de)作用。

采(cai)用數控操(cao)作，可(ke)減少生(sheng)(sheng)產工(gong)人，節約生(sheng)(sheng)產成本；采(cai)用自動檢測及監控裝(zhuang)置，精密機(ji)械加(jia)工(gong)廠家，有(you)利于提高(gao)工(gong)件的(de)(de)(de)穩定性(xing)。高(gao)精細機(ji)械制造工(gong)藝離不開(kai)高(gao)精細設備(bei)的(de)(de)(de)使用，其中(zhong)精細設備(bei)的(de)(de)(de)配件產品(pin)需(xu)要(yao)(yao)杰出的(de)(de)(de)物理安穩性(xing)能作為基礎，尤(you)其是耐高(gao)溫，耐腐(fu)蝕的(de)(de)(de)耐久(jiu)壽命作業(ye)，這關于材(cai)料(liao)的(de)(de)(de)挑(tiao)選(xuan)來說硬(ying)(ying)質合金材(cai)料(liao)無疑是首要(yao)(yao)挑(tiao)選(xuan)。對材(cai)料(liao)硬(ying)(ying)度的(de)(de)(de)要(yao)(yao)求，在一(yi)些特(te)殊(shu)情況下，材(cai)料(liao)的(de)(de)(de)硬(ying)(ying)度會越高(gao)越好，于加(jia)工(gong)零件的(de)(de)(de)硬(ying)(ying)度要(yao)(yao)求，加(jia)工(gong)之(zhi)后的(de)(de)(de)材(cai)料(liao)不應該太硬(ying)(ying)，如(ru)果其比機(ji)床(chuang)部件或者機(ji)床(chuang)刀具還硬(ying)(ying)的(de)(de)(de)話是沒法進行加(jia)工(gong)的(de)(de)(de)。

采用(yong)數控(kong)操作(zuo)(zuo)，可減(jian)少生產工人，節(jie)約生產成(cheng)本；采用(yong)自動檢測及監控(kong)裝置，有利于提高工件(jian)的(de)(de)穩定(ding)性。對零件(jian)進行這一工序呢，一般通過精密車削，研磨等(deng)操作(zuo)(zuo)，常常能(neng)讓那些有色金屬材料制(zhi)作(zuo)(zuo)的(de)(de)零件(jian)表(biao)面形成(cheng)一定(ding)的(de)(de)光潔表(biao)面，比如我們(men)常說的(de)(de)鏡(jing)面效果。進行機械加工的(de)(de)時候一定(ding)要先將其毛刺或者是磕(ke)碰傷情(qing)況(kuang)解(jie)決以后再(zai)放入到里面，這樣就(jiu)能(neng)夠減(jian)少齒(chi)輪(lun)傳動噪音的(de)(de)出現。
