數控車床可分為臥式和立式兩大類。臥式車床又有水平導軌和傾斜導軌兩種。檔次較高的數控臥車一般都采用傾斜導軌。按刀架數量分類,又可分為單刀架數控車床和雙刀架數控車,前者是兩坐標控制,后者是4坐標控制。雙刀架臥車多數采用傾斜導軌。
數控車床與普通車床一樣,也是用來加工零件旋轉表面的。一般能夠自動完成外圓柱面、圓錐面、球面以及螺紋的加工,還能加工一些復雜的回轉面,如雙曲面等。車床和普通車床的工件安裝方式基本相同,為了提高加工效率,數控車床多采用液壓、氣動和電動卡盤。
數控車床的外形與普通車床相似,即由床身、主軸箱、刀架、進給系統壓系統、冷卻和潤滑系統等部分組成。數控車床的進給系統與普通車床有質的區別,傳統普通車床有進給箱和交換齒輪架,而數控車床是直接用伺服電機通過滾珠絲杠驅動溜板和刀架實現進給運動,因而進給系統的結構大為簡化。
數控車床品種繁多,規格不一,可按如下方法進行分類。
按車床主軸位置分類
(1)立式數控車床 立式數控車床簡稱為數控立車,其車床主軸垂直于水平面,一個直徑很大的圓形工作臺,用來裝夾工件。這類機床主要用于加工徑向尺寸大、軸向尺寸相對較小的大型復雜零件。
(2)臥式數控車床 臥式數控車床又分為數控水平導軌臥式車床和數控傾斜導軌臥式車床。其傾斜導軌結構可以使車床具有更大的剛性,并易于排除切屑。
