數控(kong)(kong)機(ji)床(chuang)(chuang)其實在車工(gong)(gong)(gong)老(lao)師傅手里，都是很(hen)有靈性的(de)，用(yong)數控(kong)(kong)機(ji)床(chuang)(chuang)加工(gong)(gong)(gong)精密軸承孔(kong)(kong)的(de)時(shi)候(hou)，孔(kong)(kong)公差可以(yi)(yi)控(kong)(kong)制(zhi)到0.005mm以(yi)(yi)內(nei)，有些老(lao)師傅在精度(du)能保證(zheng)的(de)情(qing)況(kuang)下，可以(yi)(yi)控(kong)(kong)制(zhi)到0.0001mm，那么(me)分(fen)(fen)析操作(zuo)方法(fa)：1.首先(xian)把(ba)孔(kong)(kong)粗加工(gong)(gong)(gong)留余量(liang)(liang)0.15mm左右(you)，清理干凈車床(chuang)(chuang)導軌并(bing)加好導軌潤(run)滑(hua)油(you)。松開(kai)小拖(tuo)(tuo)板(ban)(ban)鎖緊螺絲轉(zhuan)動(dong)(dong)1°的(de)角度(du)后(hou)再把(ba)螺絲鎖緊，小拖(tuo)(tuo)板(ban)(ban)多退幾圈再往前歸零（目(mu)的(de)是排除絲桿間隙）。2.換精車內(nei)孔(kong)(kong)刀(dao)(dao)（注意保證(zheng)精車刀(dao)(dao)足夠鋒利(li)，不然會產生讓刀(dao)(dao)彈(dan)刀(dao)(dao)的(de)現象影響加工(gong)(gong)(gong)精度(du)），先(xian)用(yong)大拖(tuo)(tuo)板(ban)(ban)和中(zhong)(zhong)拖(tuo)(tuo)板(ban)(ban)試(shi)切一刀(dao)(dao)，中(zhong)(zhong)拖(tuo)(tuo)板(ban)(ban)不動(dong)(dong)和刀(dao)(dao)具不動(dong)(dong)原刀(dao)(dao)退回到孔(kong)(kong)口。試(shi)切后(hou)測量(liang)(liang)還(huan)剩多少余量(liang)(liang)，管(guan)你(ni)用(yong)什么(me)量(liang)(liang)具，卡尺、千分(fen)(fen)尺、內(nei)徑百(bai)分(fen)(fen)表任你(ni)選.。3.數控(kong)(kong)機(ji)床(chuang)(chuang)的(de)小拖(tuo)(tuo)板(ban)(ban)轉(zhuan)動(dong)(dong)角度(du)1°中(zhong)(zhong)拖(tuo)(tuo)板(ban)(ban)不動(dong)(dong)的(de)情(qing)況(kuang)下大托(tuo)板(ban)(ban)往前移(yi)動(dong)(dong)50mm就是0.8276mm！
