對零(ling)件(jian)進(jin)行這一工(gong)(gong)序呢，一般通過精(jing)密(mi)車削，研磨等操(cao)作(zuo)(zuo)，常常能(neng)讓那些有(you)色金屬材料制(zhi)作(zuo)(zuo)的(de)零(ling)件(jian)表(biao)(biao)面形成一定的(de)光潔表(biao)(biao)面，比如(ru)我們常說的(de)鏡面效果。機(ji)械(xie)(xie)加(jia)工(gong)(gong)的(de)優勢：機(ji)械(xie)(xie)加(jia)工(gong)(gong)不(bu)需(xu)要開模，且自由度高(gao)(gao)(gao)；機(ji)械(xie)(xie)加(jia)工(gong)(gong)的(de)精(jing)度非(fei)常高(gao)(gao)(gao)，有(you)利(li)于(yu)提(ti)高(gao)(gao)(gao)工(gong)(gong)件(jian)質(zhi)量；機(ji)械(xie)(xie)加(jia)工(gong)(gong)的(de)，精(jing)密(mi)機(ji)械(xie)(xie)加(jia)工(gong)(gong)，有(you)利(li)于(yu)提(ti)高(gao)(gao)(gao)產量。機(ji)械(xie)(xie)加(jia)工(gong)(gong)性能(neng)不(bu)僅(jin)和(he)企業的(de)利(li)益(yi)(yi)相(xiang)關，機(ji)械(xie)(xie)加(jia)工(gong)(gong)價(jia)格(ge)表(biao)(biao)，還(huan)和(he)安全(quan)性相(xiang)關，在給企業帶來經(jing)濟效益(yi)(yi)的(de)同時，還(huan)可以有(you)效降低安全(quan)事故(gu)發生(sheng)的(de)概率。

在進(jin)(jin)行機械加(jia)(jia)(jia)工(gong)的(de)時候，學會(hui)對零(ling)部件(jian)(jian)(jian)的(de)精(jing)度進(jin)(jin)行控制(zhi)是很有(you)(you)必要的(de)一(yi)件(jian)(jian)(jian)事(shi)情，因(yin)為(wei)只有(you)(you)精(jing)度得到控制(zhi)以后，才(cai)能夠讓加(jia)(jia)(jia)工(gong)出(chu)來的(de)零(ling)部件(jian)(jian)(jian)更(geng)能夠滿足精(jing)密需求。高精(jing)細(xi)(xi)機械制(zhi)造(zao)工(gong)藝離(li)不開高精(jing)細(xi)(xi)設備的(de)使用，其中(zhong)精(jing)細(xi)(xi)設備的(de)配(pei)件(jian)(jian)(jian)產(chan)品需要杰出(chu)的(de)物(wu)理安穩性能作為(wei)基礎，尤其是耐高溫，耐腐蝕的(de)耐久壽(shou)命作業(ye)，這關(guan)于材料的(de)挑(tiao)選來說硬質(zhi)合金材料無(wu)疑是首要挑(tiao)選。零(ling)部件(jian)(jian)(jian)上(shang)(shang)面(mian)有(you)(you)多(duo)個(ge)型腔，加(jia)(jia)(jia)工(gong)的(de)時候，不宜采(cai)用一(yi)個(ge)型腔一(yi)個(ge)型腔的(de)加(jia)(jia)(jia)工(gong)方式(shi)進(jin)(jin)行加(jia)(jia)(jia)工(gong)排列(lie)，這樣很容易造(zao)成零(ling)部件(jian)(jian)(jian)受(shou)力(li)不均勻(yun)而(er)產(chan)生變(bian)形，采(cai)用分層(ceng)多(duo)次(ci)(ci)加(jia)(jia)(jia)工(gong)，每一(yi)層(ceng)盡量同時加(jia)(jia)(jia)工(gong)到所有(you)(you)的(de)型腔，合肥機械加(jia)(jia)(jia)工(gong)，然后在加(jia)(jia)(jia)工(gong)上(shang)(shang)下一(yi)個(ge)層(ceng)次(ci)(ci)，讓零(ling)件(jian)(jian)(jian)均勻(yun)受(shou)力(li)減小發生形變(bian)的(de)概(gai)率。

機(ji)(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)處(chu)(chu)理(li)辦法有(you)熱處(chu)(chu)理(li)。熱處(chu)(chu)理(li)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)序的(de)(de)(de)安排是為(wei)了(le)(le)提高(gao)金(jin)屬的(de)(de)(de)切削性能，通(tong)常在機(ji)(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)前(qian)進(jin)行(xing)(xing)。為(wei)了(le)(le)消除內應力，一(yi)般(ban)在粗加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)之后，精(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)之前(qian)進(jin)行(xing)(xing)。為(wei)了(le)(le)提高(gao)零(ling)件的(de)(de)(de)機(ji)(ji)(ji)械(xie)性能，滲碳、淬火、回(hui)火等，一(yi)般(ban)經過機(ji)(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)后才進(jin)行(xing)(xing)。零(ling)部(bu)件上(shang)面(mian)有(you)多個(ge)型腔，加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)時候，不宜采用一(yi)個(ge)型腔一(yi)個(ge)型腔的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)方式進(jin)行(xing)(xing)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)排列，這樣很容易造(zao)成(cheng)零(ling)部(bu)件受力不均勻而(er)產(chan)生(sheng)變形(xing)，采用分層(ceng)多次(ci)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)，每(mei)一(yi)層(ceng)盡量(liang)同時加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)到所有(you)的(de)(de)(de)型腔，然后在加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)上(shang)下一(yi)個(ge)層(ceng)次(ci)，大型機(ji)(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)，讓零(ling)件均勻受力減小發生(sheng)形(xing)變的(de)(de)(de)概(gai)率。通(tong)過刀具的(de)(de)(de)轉動和工(gong)(gong)(gong)(gong)(gong)(gong)(gong)件的(de)(de)(de)軸向運動，銑床(chuang)完成(cheng)了(le)(le)金(jin)屬材料的(de)(de)(de)成(cheng)形(xing)。顯然，銑床(chuang)在機(ji)(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)中的(de)(de)(de)定位非(fei)常重要。
