加(jia)(jia)工(gong)中(zhong)(zhong)心常按主軸在空間所處的(de)狀(zhuang)態分為(wei)立式加(jia)(jia)工(gong)中(zhong)(zhong)心和(he)臥(wo)(wo)式加(jia)(jia)工(gong)中(zhong)(zhong)心，加(jia)(jia)工(gong)中(zhong)(zhong)心的(de)主軸在空間處于垂(chui)直狀(zhuang)態的(de)稱(cheng)為(wei)立式加(jia)(jia)工(gong)中(zhong)(zhong)心，主軸在空間處于水平(ping)狀(zhuang)態的(de)稱(cheng)為(wei)臥(wo)(wo)式加(jia)(jia)工(gong)中(zhong)(zhong)心。主軸可(ke)作垂(chui)直和(he)水平(ping)轉換的(de)，稱(cheng)為(wei)立臥(wo)(wo)式加(jia)(jia)工(gong)中(zhong)(zhong)心或五面加(jia)(jia)工(gong)中(zhong)(zhong)心，也(ye)稱(cheng)復合加(jia)(jia)工(gong)中(zhong)(zhong)心。

按加(jia)工中心運動坐標數和同(tong)時控制(zhi)的(de)坐標數分：有三軸(zhou)(zhou)(zhou)二聯動、三軸(zhou)(zhou)(zhou)三聯動、四軸(zhou)(zhou)(zhou)三聯動、五軸(zhou)(zhou)(zhou)四聯動、六軸(zhou)(zhou)(zhou)五聯動等。三軸(zhou)(zhou)(zhou)、四軸(zhou)(zhou)(zhou)是指加(jia)工中心具(ju)有的(de)運動坐標數，聯動是指控制(zhi)系統可以同(tong)時控制(zhi)運動的(de)坐標數，從(cong)而實(shi)現刀具(ju)相對工件的(de)位置和速度控制(zhi)。

按工(gong)(gong)(gong)(gong)(gong)作(zuo)臺(tai)的數量和功能(neng)分：有單(dan)工(gong)(gong)(gong)(gong)(gong)作(zuo)臺(tai)加工(gong)(gong)(gong)(gong)(gong)中心、雙工(gong)(gong)(gong)(gong)(gong)作(zuo)臺(tai)加工(gong)(gong)(gong)(gong)(gong)中心，和多工(gong)(gong)(gong)(gong)(gong)作(zuo)臺(tai)加工(gong)(gong)(gong)(gong)(gong)中心。
