數控車床機械加工是(shi)機加(jia)(jia)工(gong)(gong)(gong)中的(de)一部分。其(qi)加(jia)(jia)工(gong)(gong)(gong)方式有(you)兩種：第1種是(shi)把車刀固定(ding)，加(jia)(jia)工(gong)(gong)(gong)旋轉(zhuan)中未成(cheng)形的(de)工(gong)(gong)(gong)件(jian)(jian)，第二種是(shi)把工(gong)(gong)(gong)件(jian)(jian)固定(ding)，通過工(gong)(gong)(gong)件(jian)(jian)的(de)高速(su)旋轉(zhuan)，車刀的(de)橫向和縱向移動進行精(jing)度加(jia)(jia)工(gong)(gong)(gong)。在(zai)車床上(shang)還可用鉆頭、擴孔(kong)鉆、鉸刀、絲錐、板牙和滾花工(gong)(gong)(gong)具等進行相應(ying)的(de)加(jia)(jia)工(gong)(gong)(gong)。車床主(zhu)要用于(yu)加(jia)(jia)工(gong)(gong)(gong)軸、盤、套和其(qi)他具有(you)回轉(zhuan)表面的(de)工(gong)(gong)(gong)件(jian)(jian)。

數控車床機械加工的特點：

1.數控車床加(jia)工精度高(gao)，具有穩(wen)定的加(jia)工質(zhi)量;

2.數控車(che)床加工(gong)可進行多坐標的(de)聯動，能加工(gong)形狀復雜的(de)零件;

3.數控車床加工零件改變時，一般(ban)只需(xu)要更(geng)改數控程序，可節省生產(chan)準備(bei)時間(jian);

4.數控(kong)車床(chuang)加工本(ben)身的(de)(de)精度高、剛性大,可選擇有利的(de)(de)加工用量，生產率(lv)高(一般為普通機床(chuang)的(de)(de)3~5 倍) .
