機械(xie)加工(gong)主(zhu)要(yao)有精(jing)(jing)車、精(jing)(jing)鏜、精(jing)(jing)銑、精(jing)(jing)磨(mo)和(he)研磨(mo)等(deng)工(gong)藝。精(jing)(jing)銑：用于加工(gong)形狀(zhuang)復(fu)雜的鋁或鈹合金結(jie)構(gou)件。依靠機床(chuang)的導軌和(he)主(zhu)軸的精(jing)(jing)度來獲(huo)得(de)較(jiao)高(gao)的相互位置精(jing)(jing)度。使用經仔(zi)細研磨(mo)的金剛石刀頭進(jin)行高(gao)速銑切可獲(huo)得(de)準(zhun)確的鏡面。機械(xie)加工(gong)是(shi)通過機械(xie)設備對工(gong)件的外(wai)形尺寸或性能(neng)進(jin)行改變的加工(gong)過程，機械(xie)加工(gong)對現代工(gong)業(ye)生(sheng)產(chan)起到了非常重要(yao)的作用。在進(jin)行機械(xie)加工(gong)的時候，學會對零部(bu)件的精(jing)(jing)度進(jin)行控(kong)(kong)制(zhi)(zhi)是(shi)很(hen)有必要(yao)的一件事情，因(yin)為只有精(jing)(jing)度得(de)到控(kong)(kong)制(zhi)(zhi)以后，才(cai)能(neng)夠讓加工(gong)出來的零部(bu)件更能(neng)夠滿足(zu)精(jing)(jing)密需求。

機械(xie)(xie)加工(gong)(gong)性能(neng)(neng)不(bu)僅(jin)和(he)企(qi)業的(de)(de)(de)利益相(xiang)(xiang)關，大型機械(xie)(xie)加工(gong)(gong)廠家，還和(he)安全性相(xiang)(xiang)關，在給企(qi)業帶來(lai)經濟效(xiao)益的(de)(de)(de)同時(shi)，還可以有效(xiao)降低安全事故(gu)發生的(de)(de)(de)概率(lv)。機械(xie)(xie)加工(gong)(gong)主要有精(jing)(jing)車、精(jing)(jing)鏜、精(jing)(jing)銑(xian)、精(jing)(jing)磨(mo)和(he)研(yan)磨(mo)等(deng)工(gong)(gong)藝。精(jing)(jing)銑(xian)：用于(yu)加工(gong)(gong)形(xing)狀(zhuang)復(fu)雜(za)的(de)(de)(de)鋁或鈹合金結構(gou)件。依靠機床的(de)(de)(de)導軌和(he)主軸(zhou)的(de)(de)(de)精(jing)(jing)度(du)來(lai)獲得(de)較高的(de)(de)(de)相(xiang)(xiang)互位(wei)置精(jing)(jing)度(du)。使用經仔細研(yan)磨(mo)的(de)(de)(de)金剛石(shi)刀頭進(jin)(jin)行高速銑(xian)切(qie)可獲得(de)準確的(de)(de)(de)鏡(jing)面(mian)(mian)。對零件進(jin)(jin)行這一工(gong)(gong)序呢，一般通(tong)過精(jing)(jing)密車削，研(yan)磨(mo)等(deng)操作，常(chang)常(chang)能(neng)(neng)讓那(nei)些(xie)有色(se)金屬材料(liao)制作的(de)(de)(de)零件表面(mian)(mian)形(xing)成(cheng)一定的(de)(de)(de)光潔(jie)表面(mian)(mian)，比(bi)如我們常(chang)說的(de)(de)(de)鏡(jing)面(mian)(mian)效(xiao)果。
