數(shù)控車床可分為臥式和立式兩大類。臥式車床又有水平導(dǎo)軌和傾斜導(dǎo)軌兩種。檔次較高的數(shù)控臥車一般都采用傾斜導(dǎo)軌。按刀架數(shù)量分類，又可分為單刀架數(shù)控車床和雙刀架數(shù)控車，前者是兩坐標(biāo)控制，后者是4坐標(biāo)控制。雙刀架臥車多數(shù)采用傾斜導(dǎo)軌。
數(shù)控車床與普通車床一樣，也是用來(lái)加工零件旋轉(zhuǎn)表面的。一般能夠自動(dòng)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(fù)雜的回轉(zhuǎn)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(shù)控車床多采用液壓、氣動(dòng)和電動(dòng)卡盤。
數(shù)控車床的外形與普通車床相似，即由床身、主軸箱、刀架、進(jìn)給系統(tǒng)壓系統(tǒng)、冷卻和潤(rùn)滑系統(tǒng)等部分組成。數(shù)控車床的進(jìn)給系統(tǒng)與普通車床有質(zhì)的區(qū)別，傳統(tǒng)普通車床有進(jìn)給箱和交換齒輪架，而數(shù)控車床是直接用伺服電機(jī)通過(guò)滾珠絲杠驅(qū)動(dòng)溜板和刀架實(shí)現(xiàn)進(jìn)給運(yùn)動(dòng)，因而進(jìn)給系統(tǒng)的結(jié)構(gòu)大為簡(jiǎn)化。
數(shù)控車床品種繁多，規(guī)格不一，可按如下方法進(jìn)行分類。
按車床主軸位置分類
(1)立式數(shù)控車床 立式數(shù)控車床簡(jiǎn)稱為數(shù)控立車，其車床主軸垂直于水平面，一個(gè)直徑很大的圓形工作臺(tái)，用來(lái)裝夾工件。這類機(jī)床主要用于加工徑向尺寸大、軸向尺寸相對(duì)較小的大型復(fù)雜零件。
(2)臥式數(shù)控車床 臥式數(shù)控車床又分為數(shù)控水平導(dǎo)軌臥式車床和數(shù)控傾斜導(dǎo)軌臥式車床。其傾斜導(dǎo)軌結(jié)構(gòu)可以使車床具有更大的剛性，并易于排除切屑。
