機(ji)(ji)(ji)械(xie)(xie)加(jia)工(gong)(gong)(gong)(gong)(gong)主要(yao)有(you)精車、精鏜、精銑、精磨和研磨等(deng)工(gong)(gong)(gong)(gong)(gong)藝(yi)。精銑：用于加(jia)工(gong)(gong)(gong)(gong)(gong)形狀復雜的(de)(de)(de)(de)鋁或(huo)鈹合金(jin)結構件。依(yi)靠機(ji)(ji)(ji)床(chuang)的(de)(de)(de)(de)導軌和主軸(zhou)的(de)(de)(de)(de)精度(du)來獲得(de)較高(gao)的(de)(de)(de)(de)相互位置精度(du)。使用經(jing)仔細研磨的(de)(de)(de)(de)金(jin)剛石刀頭進(jin)行(xing)高(gao)速銑切可獲得(de)準確的(de)(de)(de)(de)鏡面。機(ji)(ji)(ji)械(xie)(xie)加(jia)工(gong)(gong)(gong)(gong)(gong)是通過機(ji)(ji)(ji)械(xie)(xie)設(she)備對(dui)工(gong)(gong)(gong)(gong)(gong)件的(de)(de)(de)(de)外形尺寸(cun)或(huo)性能進(jin)行(xing)改變的(de)(de)(de)(de)加(jia)工(gong)(gong)(gong)(gong)(gong)過程，機(ji)(ji)(ji)械(xie)(xie)加(jia)工(gong)(gong)(gong)(gong)(gong)對(dui)現代工(gong)(gong)(gong)(gong)(gong)業生產起到(dao)了非常重(zhong)要(yao)的(de)(de)(de)(de)作用。在進(jin)行(xing)機(ji)(ji)(ji)械(xie)(xie)加(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)(de)時候，學會對(dui)零(ling)部(bu)件的(de)(de)(de)(de)精度(du)進(jin)行(xing)控制(zhi)是很有(you)必要(yao)的(de)(de)(de)(de)一件事情，因為只有(you)精度(du)得(de)到(dao)控制(zhi)以后(hou)，才能夠讓加(jia)工(gong)(gong)(gong)(gong)(gong)出來的(de)(de)(de)(de)零(ling)部(bu)件更能夠滿足精密需求。

機(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)(de)處理(li)(li)辦法有(you)熱處理(li)(li)。熱處理(li)(li)工(gong)(gong)(gong)(gong)序的(de)(de)(de)(de)安(an)排是為(wei)了提(ti)高(gao)金屬(shu)的(de)(de)(de)(de)切削(xue)性能，通常在(zai)機(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)前進(jin)行(xing)。為(wei)了消除內(nei)應力，一(yi)(yi)般在(zai)粗加(jia)(jia)工(gong)(gong)(gong)(gong)之(zhi)(zhi)后(hou)，精(jing)(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)之(zhi)(zhi)前進(jin)行(xing)。為(wei)了提(ti)高(gao)零(ling)件(jian)的(de)(de)(de)(de)機(ji)(ji)械(xie)性能，滲碳、淬火、回(hui)火等，一(yi)(yi)般經過機(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)后(hou)才進(jin)行(xing)。零(ling)部(bu)件(jian)上面(mian)有(you)多個型(xing)腔，加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)(de)時候，不宜采用(yong)一(yi)(yi)個型(xing)腔一(yi)(yi)個型(xing)腔的(de)(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)方(fang)式進(jin)行(xing)加(jia)(jia)工(gong)(gong)(gong)(gong)排列，這(zhe)樣很容易(yi)造成(cheng)零(ling)部(bu)件(jian)受力不均勻而產生(sheng)變形，精(jing)(jing)(jing)密機(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)廠(chang)家，采用(yong)分層(ceng)多次加(jia)(jia)工(gong)(gong)(gong)(gong)，每(mei)一(yi)(yi)層(ceng)盡量同(tong)時加(jia)(jia)工(gong)(gong)(gong)(gong)到所有(you)的(de)(de)(de)(de)型(xing)腔，然后(hou)在(zai)加(jia)(jia)工(gong)(gong)(gong)(gong)上下一(yi)(yi)個層(ceng)次，讓零(ling)件(jian)均勻受力減小發(fa)生(sheng)形變的(de)(de)(de)(de)概率(lv)。精(jing)(jing)(jing)密零(ling)件(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)其實是機(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)(de)一(yi)(yi)種，但是因為(wei)對零(ling)件(jian)的(de)(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)(jing)密度較(jiao)高(gao)，對生(sheng)產機(ji)(ji)械(xie)及流程要求也比較(jiao)高(gao)。隨著工(gong)(gong)(gong)(gong)業化發(fa)展，機(ji)(ji)械(xie)精(jing)(jing)(jing)密加(jia)(jia)工(gong)(gong)(gong)(gong)廠(chang)，精(jing)(jing)(jing)密機(ji)(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)分類越來(lai)越多，方(fang)向越來(lai)越細，越來(lai)越化。

在(zai)機(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)領域中(zhong)，在(zai)進行零件(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)之前(qian)需要了解材(cai)料的(de)(de)(de)(de)(de)(de)(de)(de)密度(du)，如果(guo)密度(du)太大，那么(me)其對應(ying)的(de)(de)(de)(de)(de)(de)(de)(de)硬(ying)(ying)度(du)也就越(yue)大，如果(guo)硬(ying)(ying)度(du)超過(guo)了機(ji)床的(de)(de)(de)(de)(de)(de)(de)(de)硬(ying)(ying)度(du)，就沒法實施加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，如果(guo)遇到(dao)這樣的(de)(de)(de)(de)(de)(de)(de)(de)情況還是進行加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)(de)(de)(de)(de)(de)話，不(bu)僅會(hui)損壞零件(jian)，還會(hui)造成其他的(de)(de)(de)(de)(de)(de)(de)(de)危險，附近機(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，比方說崩刀、損壞機(ji)床等(deng)，因(yin)此，機(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)領域中(zhong)，加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)材(cai)質應(ying)該要低于刀具(ju)的(de)(de)(de)(de)(de)(de)(de)(de)硬(ying)(ying)度(du)，這樣的(de)(de)(de)(de)(de)(de)(de)(de)材(cai)料才適合(he)做精密機(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)。零部(bu)件(jian)上(shang)面有(you)(you)多個(ge)型(xing)腔(qiang)，加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)(de)(de)(de)(de)(de)時候，不(bu)宜采(cai)用一(yi)(yi)個(ge)型(xing)腔(qiang)一(yi)(yi)個(ge)型(xing)腔(qiang)的(de)(de)(de)(de)(de)(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)方式(shi)進行加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)排列(lie)，這樣很(hen)容(rong)易造成零部(bu)件(jian)受(shou)力不(bu)均勻(yun)而產生(sheng)變(bian)形，采(cai)用分層(ceng)(ceng)多次(ci)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，每一(yi)(yi)層(ceng)(ceng)盡量同時加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)到(dao)所有(you)(you)的(de)(de)(de)(de)(de)(de)(de)(de)型(xing)腔(qiang)，然后在(zai)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)上(shang)下一(yi)(yi)個(ge)層(ceng)(ceng)次(ci)，讓零件(jian)均勻(yun)受(shou)力減小發生(sheng)形變(bian)的(de)(de)(de)(de)(de)(de)(de)(de)概率(lv)。機(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)以后的(de)(de)(de)(de)(de)(de)(de)(de)零部(bu)件(jian)放在(zai)含有(you)(you)磨(mo)塊或者(zhe)是磨(mo)劑的(de)(de)(de)(de)(de)(de)(de)(de)滾筒當中(zhong)，在(zai)里(li)面會(hui)進行復雜(za)的(de)(de)(de)(de)(de)(de)(de)(de)運動，而運動的(de)(de)(de)(de)(de)(de)(de)(de)過(guo)程當中(zhong)會(hui)產生(sheng)壓力，亳州機(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，產生(sheng)壓力會(hui)出現碰撞(zhuang)和滾壓，這樣就會(hui)讓零部(bu)件(jian)的(de)(de)(de)(de)(de)(de)(de)(de)表面起到(dao)輕(qing)微磨(mo)削的(de)(de)(de)(de)(de)(de)(de)(de)效果(guo)，自然也就能夠實現讓它的(de)(de)(de)(de)(de)(de)(de)(de)表面慢慢被細(xi)化，表面也會(hui)因(yin)此變(bian)得光整(zheng)很(hen)多。
