機(ji)械數控(kong)機(ji)床加(jia)(jia)工(gong)(gong)(gong)有(you)下列(lie)優點：1、加(jia)(jia)工(gong)(gong)(gong)精(jing)(jing)度高(gao)，加(jia)(jia)工(gong)(gong)(gong)質量穩定，重復(fu)精(jing)(jing)度高(gao)，適應的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)要求。2、可加(jia)(jia)工(gong)(gong)(gong)常規方法難(nan)于(yu)加(jia)(jia)工(gong)(gong)(gong)的(de)(de)(de)復(fu)雜型面，甚至能加(jia)(jia)工(gong)(gong)(gong)一些無法觀測的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)部位。數控(kong)加(jia)(jia)工(gong)(gong)(gong)的(de)(de)(de)缺點是車床設備費(fei)用昂貴，要求維修人員具有(you)較(jiao)高(gao)水平。3、大量減(jian)少工(gong)(gong)(gong)裝數量，加(jia)(jia)工(gong)(gong)(gong)形(xing)狀(zhuang)復(fu)雜的(de)(de)(de)零(ling)件(jian)不(bu)需要復(fu)雜的(de)(de)(de)工(gong)(gong)(gong)裝。如要改變零(ling)件(jian)的(de)(de)(de)形(xing)狀(zhuang)和尺寸，只需要修改零(ling)件(jian)加(jia)(jia)工(gong)(gong)(gong)程序(xu)，適用于(yu)新產(chan)(chan)品(pin)研制和改型。4、多(duo)品(pin)種、小批(pi)量生(sheng)產(chan)(chan)情況下生(sheng)產(chan)(chan)效率較(jiao)高(gao)，能減(jian)少生(sheng)產(chan)(chan)準(zhun)備、車床調整和工(gong)(gong)(gong)序(xu)檢驗(yan)的(de)(de)(de)時(shi)間，而且由(you)于(yu)使用佳(jia)切削量而減(jian)少了切削時(shi)間。

機械數(shu)控機床其實在(zai)車(che)(che)工(gong)老(lao)(lao)師(shi)傅手里，都是(shi)很有(you)靈性的(de)，用機械數(shu)控機床加工(gong)精(jing)(jing)密軸承孔的(de)時候，孔公(gong)差可以控制到(dao)(dao)0.005mm以內(nei)，有(you)些老(lao)(lao)師(shi)傅在(zai)精(jing)(jing)度(du)能保證的(de)情況下，可以控制到(dao)(dao)0.0001mm，那么(me)(me)分(fen)(fen)析操作方法：1.首先把孔粗加工(gong)留余(yu)量(liang)(liang)(liang)0.15mm左(zuo)右(you)，清理干凈車(che)(che)床導(dao)軌并(bing)加好(hao)導(dao)軌潤滑(hua)油。松開(kai)小拖(tuo)(tuo)板(ban)鎖緊(jin)螺絲(si)轉(zhuan)動(dong)(dong)(dong)1°的(de)角度(du)后再把螺絲(si)鎖緊(jin)，小拖(tuo)(tuo)板(ban)多(duo)(duo)退(tui)幾圈再往前歸零(ling)（目的(de)是(shi)排除(chu)絲(si)桿間隙）。2.換精(jing)(jing)車(che)(che)內(nei)孔刀(dao)（注意保證精(jing)(jing)車(che)(che)刀(dao)足夠鋒利，不然會產生讓刀(dao)彈(dan)刀(dao)的(de)現象影響加工(gong)精(jing)(jing)度(du)），先用大拖(tuo)(tuo)板(ban)和(he)中拖(tuo)(tuo)板(ban)試切一(yi)刀(dao)，中拖(tuo)(tuo)板(ban)不動(dong)(dong)(dong)和(he)刀(dao)具不動(dong)(dong)(dong)原刀(dao)退(tui)回到(dao)(dao)孔口(kou)。試切后測量(liang)(liang)(liang)還剩多(duo)(duo)少(shao)余(yu)量(liang)(liang)(liang)，管你用什(shen)么(me)(me)量(liang)(liang)(liang)具，卡(ka)尺、千分(fen)(fen)尺、內(nei)徑(jing)百分(fen)(fen)表任你選.。3.機械數(shu)控機床的(de)小拖(tuo)(tuo)板(ban)轉(zhuan)動(dong)(dong)(dong)角度(du)1°中拖(tuo)(tuo)板(ban)不動(dong)(dong)(dong)的(de)情況下大托板(ban)往前移(yi)動(dong)(dong)(dong)50mm就(jiu)是(shi)0.8276mm！
