假如數(shu)(shu)控車(che)(che)床(chuang)(chuang)(chuang)車(che)(che)床(chuang)(chuang)(chuang)溜板(ban)的(de)(de)(de)(de)行程小(xiao)于(yu)3000mm，車(che)(che)床(chuang)(chuang)(chuang)溜板(ban)移動(dong)在(zai)水平面內直(zhi)線(xian)度(du)差錯的(de)(de)(de)(de)檢查(cha)(cha)(cha)可用長(chang)圓柱查(cha)(cha)(cha)驗(yan)(yan)棒檢查(cha)(cha)(cha)。在(zai)前后尖間，頂緊一根長(chang)圓柱查(cha)(cha)(cha)驗(yan)(yan)棒，將千分(fen)表(biao)(biao)固定在(zai)溜板(ban)上(shang)，使(shi)千分(fen)表(biao)(biao)測頭(tou)頂在(zai)查(cha)(cha)(cha)驗(yan)(yan)棒的(de)(de)(de)(de)側母線(xian)上(shang)。調整(zheng)尾座(zuo)，使(shi)千分(fen)表(biao)(biao)在(zai)查(cha)(cha)(cha)驗(yan)(yan)棒兩頭(tou)的(de)(de)(de)(de)讀(du)數(shu)(shu)持平。移動(dong)溜板(ban)，在(zai)溜板(ban)的(de)(de)(de)(de)悉數(shu)(shu)行程上(shang)檢查(cha)(cha)(cha)。千分(fen)表(biao)(biao)在(zai)1000mm行程上(shang)的(de)(de)(de)(de)讀(du)數(shu)(shu)較大差值，即是代理直(zhi)線(xian)度(du)差錯。

有(you)條件時亦可使用光學(xue)平(ping)直(zhi)儀(yi)檢查，將縱(zong)切(qie)車床(chuang)(chuang)光學(xue)平(ping)直(zhi)儀(yi)置于機(ji)床(chuang)(chuang)一端，反(fan)射鏡(jing)置于溜板或(huo)作(zuo)(zuo)業臺(tai)面(mian)上(shang)，在行(xing)程(cheng)的兩個極限方位(wei)，調整平(ping)直(zhi)儀(yi)及反(fan)射鏡(jing)，使平(ping)行(xing)光管的亮十字像同可動(dong)分(fen)劃板的準線(xian)重合。作(zuo)(zuo)業臺(tai)每移動(dong)500mm，廠(chang)家讀(du)數(shu)一次(ci)并作(zuo)(zuo)好記載，將讀(du)數(shu)順(shun)次(ci)擺放(fang)畫出作(zuo)(zuo)業臺(tai)的運動(dong)曲線(xian)，再(zai)核算1000mm長度上(shang)和行(xing)程(cheng)全(quan)長上(shang)的差錯(cuo)值。

檢查外圓磨床(chuang)機(ji)床(chuang)作(zuo)業臺(tai)(tai)移動(dong)在筆直平面(mian)內的(de)(de)直線(xian)度差(cha)錯。在作(zuo)業臺(tai)(tai)基(ji)(ji)地放一(yi)(yi)個隨(sui)機(ji)床(chuang)附(fu)帶的(de)(de)橋板(ban)，或克己(ji)的(de)(de)專用(yong)橋板(ban)（只用(yong)于斜臺(tai)(tai)面(mian)，平臺(tai)(tai)面(mian)不(bu)需用(yong)橋板(ban)）。在橋板(ban)基(ji)(ji)地與作(zuo)業臺(tai)(tai)移動(dong)的(de)(de)方向平行放置一(yi)(yi)個水平儀。移動(dong)作(zuo)業臺(tai)(tai)，每隔250mm記載(zai)一(yi)(yi)次(ci)讀數（短床(chuang)身在較大磨削長度的(de)(de)兩頭和基(ji)(ji)地三(san)個方位檢查），將水平儀讀數順次(ci)擺放，畫出(chu)作(zuo)業臺(tai)(tai)的(de)(de)運動(dong)曲線(xian)。天津市(shi)在1000mm長度上(shang)的(de)(de)運動(dong)曲線(xian)至(zhi)兩頭點連線(xian)間的(de)(de)較大坐標值(zhi)，即是1000mm長度上(shang)的(de)(de)直線(xian)度差(cha)錯。
