坐(zuo)標鏜床的(de)(de)(de)(de)(de)定(ding)(ding)位(wei)精(jing)度需求是比較高的(de)(de)(de)(de)(de)，所以沈陽(yang)車床進(jin)口要檢(jian)(jian)查作業(ye)臺或(huo)主(zhu)軸(zhou)箱在移動坐(zuo)標定(ding)(ding)位(wei)后的(de)(de)(de)(de)(de)定(ding)(ding)位(wei)差(cha)(cha)(cha)錯(cuo)。國產各式(shi)坐(zuo)標鏜床的(de)(de)(de)(de)(de)定(ding)(ding)位(wei)體系(xi)有光(guang)學(xue)體系(xi)（即(ji)絲杠(gang)和(he)校對尺(chi)）。選用的(de)(de)(de)(de)(de)定(ding)(ding)位(wei)體系(xi)雖(sui)不一(yi)(yi)樣，但定(ding)(ding)位(wei)差(cha)(cha)(cha)錯(cuo)的(de)(de)(de)(de)(de)丈量辦法是一(yi)(yi)樣的(de)(de)(de)(de)(de)。在機床臺上，沿縱向(xiang)移動方向(xiang)放置一(yi)(yi)個精(jing)細的(de)(de)(de)(de)(de)刻線(xian)(xian)(xian)(xian)尺(chi)（刻線(xian)(xian)(xian)(xian)尺(chi)的(de)(de)(de)(de)(de)刻線(xian)(xian)(xian)(xian)精(jing)度應(ying)帶差(cha)(cha)(cha)錯(cuo)檢(jian)(jian)定(ding)(ding)表，檢(jian)(jian)定(ding)(ding)精(jing)度在0.0005mm以內），刻線(xian)(xian)(xian)(xian)尺(chi)放在作業(ye)臺的(de)(de)(de)(de)(de)基地，高度應(ying)在作業(ye)臺面(mian)至筆直主(zhu)軸(zhou)端面(mian)較大(da)間隔的(de)(de)(de)(de)(de)l/3~l/2處。將讀數(shu)(shu)顯微鏡(jing)（其(qi)讀數(shu)(shu)精(jing)度為0.001~0.002mm）固定(ding)(ding)在主(zhu)軸(zhou)套(tao)筒上，使顯微鏡(jing)能明晰地觀察(cha)到刻線(xian)(xian)(xian)(xian)尺(chi)上的(de)(de)(de)(de)(de)刻線(xian)(xian)(xian)(xian)，對作業(ye)臺在規(gui)則長度上的(de)(de)(de)(de)(de)移動進(jin)行(xing)檢(jian)(jian)查（通(tong)常規(gui)則每(mei)移動l0mm讀數(shu)(shu)一(yi)(yi)次）。在讀數(shu)(shu)時(shi)，作業(ye)臺應(ying)夾緊(jin)。定(ding)(ding)位(wei)差(cha)(cha)(cha)錯(cuo)是恣意兩次定(ding)(ding)位(wei)時(shi)讀數(shu)(shu)的(de)(de)(de)(de)(de)實踐差(cha)(cha)(cha)值(zhi)的(de)(de)(de)(de)(de)大(da)代數(shu)(shu)差(cha)(cha)(cha)。

這一時期，數控機床銷(xiao)售靠(kao)苦“熬”行不通(tong)了。杰克機床有(you)限公司董事(shi)長陳(chen)華貴說，這次(ci)危機與(yu)2008年不同(tong)，如(ru)果說當(dang)年就如(ru)同(tong)一次(ci)地震，企業(ye)只要(yao)(yao)保存實(shi)力等待救援(yuan)就可以了；而(er)這次(ci)情(qing)況要(yao)(yao)復雜很多，綜合了各方面的因素，本(ben)質上(shang)(shang)是(shi)一種(zhong)產能(neng)的過(guo)剩，是(shi)一次(ci)擠泡沫的過(guo)程，企業(ye)必須搶先自救。他認為，雖(sui)然現(xian)在因為市(shi)場低迷，企業(ye)競爭加(jia)大，但絕沒有(you)到達慘烈的程度，最(zui)多也就是(shi)比較難受。“如(ru)果一場戰役一個團的人(ren)上(shang)(shang)去，能(neng)全身而(er)退的還有(you)上(shang)(shang)百號(hao)人(ren)，那絕說不上(shang)(shang)慘烈。”
