機械(xie)數(shu)控(kong)(kong)機床加(jia)(jia)工(gong)(gong)(gong)有下列優點(dian)：1、加(jia)(jia)工(gong)(gong)(gong)精度高(gao)，加(jia)(jia)工(gong)(gong)(gong)質量(liang)穩定，重(zhong)復(fu)精度高(gao)，適應的(de)(de)加(jia)(jia)工(gong)(gong)(gong)要(yao)求。2、可(ke)加(jia)(jia)工(gong)(gong)(gong)常規(gui)方法(fa)(fa)難(nan)于(yu)加(jia)(jia)工(gong)(gong)(gong)的(de)(de)復(fu)雜型面，甚至(zhi)能加(jia)(jia)工(gong)(gong)(gong)一些無法(fa)(fa)觀測(ce)的(de)(de)加(jia)(jia)工(gong)(gong)(gong)部位。數(shu)控(kong)(kong)加(jia)(jia)工(gong)(gong)(gong)的(de)(de)缺點(dian)是車(che)床設備費用昂貴，要(yao)求維修人員具有較高(gao)水平(ping)。3、大量(liang)減少(shao)工(gong)(gong)(gong)裝(zhuang)數(shu)量(liang)，加(jia)(jia)工(gong)(gong)(gong)形狀復(fu)雜的(de)(de)零件不(bu)需要(yao)復(fu)雜的(de)(de)工(gong)(gong)(gong)裝(zhuang)。如要(yao)改變零件的(de)(de)形狀和尺寸，只需要(yao)修改零件加(jia)(jia)工(gong)(gong)(gong)程序(xu)，適用于(yu)新(xin)產(chan)品研制和改型。4、多品種(zhong)、小(xiao)批量(liang)生(sheng)產(chan)情(qing)況(kuang)下生(sheng)產(chan)效(xiao)率較高(gao)，能減少(shao)生(sheng)產(chan)準備、車(che)床調整和工(gong)(gong)(gong)序(xu)檢(jian)驗的(de)(de)時(shi)間，而且由于(yu)使用佳切削量(liang)而減少(shao)了切削時(shi)間。
