機械加工的工藝內容有哪些呢？

機械加工(gong)包(bao)括：

車(che)削（立車(che)、臥車(che)）：車(che)削是從工(gong)件(jian)上切(qie)除金屬(shu)的加(jia)工(gong)。在工(gong)件(jian)旋轉的同時，刀具切(qie)入(ru)工(gong)件(jian)或(huo)沿(yan)著工(gong)件(jian)車(che)削；

銑(xian)(xian)削(xue)（立銑(xian)(xian)、臥銑(xian)(xian)）：銑(xian)(xian)削(xue)是使(shi)用旋(xuan)轉(zhuan)刀具切除(chu)金屬的加(jia)工(gong)，主要用于加(jia)工(gong)槽(cao)和外形直(zhi)線面(mian)，也可以兩軸或者三(san)軸聯動(dong)加(jia)工(gong)弧(hu)面(mian)；

鏜孔(kong)(kong)：鏜孔(kong)(kong)是把(ba)工(gong)(gong)(gong)件(jian)上已鉆出(chu)或鑄出(chu)的孔(kong)(kong)加(jia)(jia)以擴大(da)或作(zuo)進一(yi)步加(jia)(jia)工(gong)(gong)(gong)的加(jia)(jia)工(gong)(gong)(gong)方法。主要用于加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)件(jian)外形較(jiao)(jiao)大(da)、直徑(jing)較(jiao)(jiao)大(da)、精度(du)較(jiao)(jiao)高的孔(kong)(kong)加(jia)(jia)工(gong)(gong)(gong)。

刨(bao)削：刨(bao)削主要(yao)特性是加工外形(xing)直線(xian)面，一般(ban)情況下表(biao)面粗糙度沒(mei)有銑床高；

插削(xue)：插削(xue)實際上是立式刨(bao)床，它的刀(dao)具是上下(xia)運動(dong)的，非(fei)常適合(he)非(fei)完(wan)整圓(yuan)弧加工，主要用于切削(xue)某些類型(xing)的齒輪(lun)；

磨(mo)(mo)削(xue)（平面磨(mo)(mo)、外圓磨(mo)(mo)、內(nei)孔(kong)磨(mo)(mo)、工(gong)具磨(mo)(mo)等）：磨(mo)(mo)削(xue)是使用磨(mo)(mo)削(xue)輪來切除金屬的加工(gong)方法，加工(gong)后(hou)的工(gong)件(jian)尺寸準確(que)、表面光潔。主要用于對(dui)經過(guo)熱處(chu)理的工(gong)件(jian)進行(xing)精加工(gong)，使其達(da)到準確(que)的尺寸。

鉆(zhan)(zhan)(zhan)削(xue)：鉆(zhan)(zhan)(zhan)削(xue)是使(shi)用旋轉鉆(zhan)(zhan)(zhan)頭(tou)在實心金屬工(gong)件(jian)上(shang)進行鉆(zhan)(zhan)(zhan)孔(kong)加工(gong)；鉆(zhan)(zhan)(zhan)孔(kong)時，工(gong)件(jian)定位夾(jia)緊、固(gu)定不動(dong)；鉆(zhan)(zhan)(zhan)頭(tou)除旋轉外還(huan)要沿(yan)自身軸線作進給運動(dong)。

機(ji)(ji)械加(jia)工(gong)(gong)包含的加(jia)工(gong)(gong)類型比(bi)較(jiao)多，以上介紹的幾種(zhong)是(shi)目前比(bi)較(jiao)常見的機(ji)(ji)械加(jia)工(gong)(gong)類型，這些機(ji)(ji)械加(jia)工(gong)(gong)類型可(ke)以滿足目前所有工(gong)(gong)件(jian)所需的機(ji)(ji)械加(jia)工(gong)(gong)工(gong)(gong)藝(yi)。
