機(ji)械(xie)(xie)(xie)加(jia)(jia)工(gong)(gong)是(shi)一(yi)種用(yong)加(jia)(jia)工(gong)(gong)機(ji)械(xie)(xie)(xie)對工(gong)(gong)件(jian)的(de)(de)外形尺寸或(huo)性(xing)能(neng)(neng)進(jin)行(xing)改變的(de)(de)過程。按被(bei)加(jia)(jia)工(gong)(gong)的(de)(de)工(gong)(gong)件(jian)處于(yu)的(de)(de)溫(wen)度(du)狀態﹐分為(wei)(wei)冷(leng)加(jia)(jia)工(gong)(gong)和(he)熱加(jia)(jia)工(gong)(gong)。采用(yong)數控(kong)操作，可減少生產工(gong)(gong)人，機(ji)械(xie)(xie)(xie)加(jia)(jia)工(gong)(gong)中心，節約(yue)生產成本(ben)；采用(yong)自動檢測及監(jian)控(kong)裝置(zhi)，安徽機(ji)械(xie)(xie)(xie)加(jia)(jia)工(gong)(gong)，有利于(yu)提高(gao)工(gong)(gong)件(jian)的(de)(de)穩定(ding)性(xing)。機(ji)械(xie)(xie)(xie)加(jia)(jia)工(gong)(gong)的(de)(de)處理(li)辦(ban)法有熱處理(li)。熱處理(li)工(gong)(gong)序的(de)(de)安排(pai)是(shi)為(wei)(wei)了提高(gao)金屬(shu)的(de)(de)切(qie)削性(xing)能(neng)(neng)，通常在機(ji)械(xie)(xie)(xie)加(jia)(jia)工(gong)(gong)前進(jin)行(xing)。為(wei)(wei)了消除內應力，一(yi)般在粗加(jia)(jia)工(gong)(gong)之(zhi)后(hou)，精(jing)加(jia)(jia)工(gong)(gong)之(zhi)前進(jin)行(xing)。為(wei)(wei)了提高(gao)零件(jian)的(de)(de)機(ji)械(xie)(xie)(xie)性(xing)能(neng)(neng)，滲碳、淬火(huo)、回火(huo)等，一(yi)般經過機(ji)械(xie)(xie)(xie)加(jia)(jia)工(gong)(gong)后(hou)才進(jin)行(xing)。

零(ling)(ling)部件(jian)上(shang)面有多個(ge)型(xing)腔，加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)時(shi)(shi)候(hou)，數控機(ji)(ji)(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中心(xin)，不宜采用(yong)(yong)一個(ge)型(xing)腔一個(ge)型(xing)腔的(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)方式進行加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)排列，這樣很容易造成(cheng)零(ling)(ling)部件(jian)受(shou)力不均(jun)勻(yun)而產生變(bian)(bian)形(xing)，采用(yong)(yong)分(fen)層多次加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，每一層盡量同時(shi)(shi)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)到(dao)所有的(de)(de)型(xing)腔，然后在加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)上(shang)下(xia)一個(ge)層次，讓(rang)零(ling)(ling)件(jian)均(jun)勻(yun)受(shou)力減小(xiao)發生形(xing)變(bian)(bian)的(de)(de)概率。精密(mi)機(ji)(ji)(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)形(xing)式根據不同的(de)(de)材質工(gong)(gong)(gong)(gong)(gong)件(jian)和(he)產品(pin)的(de)(de)要求(qiu)而有所差別。傳統的(de)(de)精密(mi)機(ji)(ji)(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)方法就是我們經常聽到(dao)的(de)(de)車、鉗、洗、刨、磨(mo)這些。而隨著機(ji)(ji)(ji)(ji)械(xie)科技的(de)(de)發展，在精密(mi)機(ji)(ji)(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)方面，還(huan)出現了電鍍、線切割、鑄造、鍛(duan)造和(he)粉(fen)末加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)等(deng)等(deng)。機(ji)(ji)(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)是一種用(yong)(yong)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)機(ji)(ji)(ji)(ji)械(xie)對工(gong)(gong)(gong)(gong)(gong)件(jian)的(de)(de)外形(xing)尺寸(cun)或性能進行改變(bian)(bian)的(de)(de)過程。按被加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)工(gong)(gong)(gong)(gong)(gong)件(jian)處于的(de)(de)溫度(du)狀態﹐分(fen)為冷加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)和(he)熱(re)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)。

機械(xie)加工(gong)(gong)(gong)(gong)主要有(you)(you)精(jing)車、精(jing)鏜、精(jing)銑(xian)、精(jing)磨和(he)研磨等工(gong)(gong)(gong)(gong)藝。精(jing)銑(xian)：用于加工(gong)(gong)(gong)(gong)形狀復(fu)雜的(de)(de)(de)(de)鋁或(huo)鈹合(he)金結構件(jian)。依(yi)靠機床的(de)(de)(de)(de)導軌和(he)主軸的(de)(de)(de)(de)精(jing)度(du)來獲得(de)較(jiao)高(gao)的(de)(de)(de)(de)相互位置精(jing)度(du)。使(shi)用經(jing)仔細(xi)研磨的(de)(de)(de)(de)金剛石刀頭進(jin)行高(gao)速銑(xian)切可獲得(de)準確的(de)(de)(de)(de)鏡面(mian)(mian)。機械(xie)加工(gong)(gong)(gong)(gong)以(yi)后的(de)(de)(de)(de)零(ling)部件(jian)放在(zai)含有(you)(you)磨塊(kuai)或(huo)者是磨劑(ji)的(de)(de)(de)(de)滾(gun)筒(tong)當(dang)中，在(zai)里面(mian)(mian)會(hui)進(jin)行復(fu)雜的(de)(de)(de)(de)運動，而運動的(de)(de)(de)(de)過程當(dang)中會(hui)產(chan)生壓(ya)力(li)(li)，產(chan)生壓(ya)力(li)(li)會(hui)出現(xian)碰撞(zhuang)和(he)滾(gun)壓(ya)，這樣就會(hui)讓(rang)(rang)零(ling)部件(jian)的(de)(de)(de)(de)表面(mian)(mian)起(qi)到輕微磨削的(de)(de)(de)(de)效(xiao)果，機械(xie)加工(gong)(gong)(gong)(gong)公司，自(zi)然也就能(neng)夠實現(xian)讓(rang)(rang)它的(de)(de)(de)(de)表面(mian)(mian)慢(man)慢(man)被細(xi)化，表面(mian)(mian)也會(hui)因(yin)此變得(de)光(guang)整很(hen)多。機械(xie)加工(gong)(gong)(gong)(gong)性能(neng)不僅和(he)企業(ye)的(de)(de)(de)(de)利益相關，還和(he)安全性相關，在(zai)給企業(ye)帶來經(jing)濟效(xiao)益的(de)(de)(de)(de)同時(shi)，還可以(yi)有(you)(you)效(xiao)降低(di)安全事故發(fa)生的(de)(de)(de)(de)概率。
