通常(chang)河北反(fan)轉作業(ye)臺是銑床的(de)(de)附件，自動(dong)(dong)化車床分(fen)(fen)度精度較(jiao)低，故可選用八方檢(jian)(jian)(jian)(jian)具(ju)進(jin)(jin)行檢(jian)(jian)(jian)(jian)查。八方檢(jian)(jian)(jian)(jian)具(ju)的(de)(de)外(wai)接圓直徑250mm。在(zai)(zai)(zai)作業(ye)臺錐孔中嚴(yan)密刺進(jin)(jin)八方檢(jian)(jian)(jian)(jian)具(ju)的(de)(de)定(ding)位心軸，以確保作業(ye)臺反(fan)轉基(ji)地(di)與八方檢(jian)(jian)(jian)(jian)具(ju)外(wai)接圓基(ji)地(di)重合(he)。 將(jiang)(jiang)被檢(jian)(jian)(jian)(jian)作業(ye)臺固定(ding)于查驗平(ping)板上(shang)(shang)，將(jiang)(jiang)千(qian)(qian)分(fen)(fen)表(biao)底座上(shang)(shang)的(de)(de)凸緣靠(kao)(kao)緊在(zai)(zai)(zai)查驗平(ping)板上(shang)(shang)導(dao)(dao)向(xiang)槽的(de)(de)旁邊面沒有(you)導(dao)(dao)向(xiang)槽的(de)(de)可用平(ping)尺替代)，使(shi)千(qian)(qian)分(fen)(fen)表(biao)測頭頂在(zai)(zai)(zai)八方檢(jian)(jian)(jian)(jian)具(ju)的(de)(de)一邊上(shang)(shang)，沿導(dao)(dao)向(xiang)槽移動(dong)(dong)千(qian)(qian)分(fen)(fen)表(biao)座，使(shi)千(qian)(qian)分(fen)(fen)表(biao)在(zai)(zai)(zai)兩(liang)處的(de)(de)讀數一樣（靠(kao)(kao)滾動(dong)(dong)蝸桿(gan)手柄來調(diao)整(zheng)）。然后將(jiang)(jiang)作業(ye)臺轉過45°（即360°/8），千(qian)(qian)分(fen)(fen)表(biao)在(zai)(zai)(zai)另一邊的(de)(de)悉數長度上(shang)(shang)檢(jian)(jian)(jian)(jian)查，順次檢(jian)(jian)(jian)(jian)查各邊。千(qian)(qian)分(fen)(fen)表(biao)在(zai)(zai)(zai)恣意(yi)一邊兩(liang)頭讀數的(de)(de)較(jiao)大差值(zhi)即是分(fen)(fen)度差錯。

數控機床(chuang)檢(jian)查(cha)作業(ye)臺(tai)(tai)移動(dong)對水平銑頭(tou)主(zhu)軸軸線(xian)的(de)(de)筆直度(du)差(cha)(cha)錯的(de)(de)辦法(fa)。銷售檢(jian)查(cha)時，將(jiang)進口(kou)水平銑頭(tou)固定在(zai)接近作業(ye)臺(tai)(tai)面(mian)的(de)(de)方位(wei)，夾緊(jin)主(zhu)軸套筒(tong)，可(ke)旋轉視(shi)點(dian)的(de)(de)銑頭(tou)應調(diao)整到零(ling)位(wei)。作業(ye)臺(tai)(tai)移至導軌基地，即離(li)主(zhu)軸軸線(xian)L/2的(de)(de)當地，并在(zai)作業(ye)臺(tai)(tai)T形槽中(zhong)放一(yi)專用(yong)滑(hua)塊，使滑(hua)塊凸緣緊(jin)靠在(zai)基地T形槽的(de)(de)旁(pang)邊(bian)面(mian)上(shang)。在(zai)主(zhu)軸上(shang)固定一(yi)個角(jiao)形表桿，使千(qian)分表測頭(tou)頂在(zai)滑(hua)塊的(de)(de)旁(pang)邊(bian)面(mian)上(shang)，記下表的(de)(de)讀(du)數。滑(hua)塊不動(dong)，移動(dong)作業(ye)臺(tai)(tai)L長度(du)后（L的(de)(de)長度(du)按(an)機床(chuang)不一(yi)樣規(gui)格(ge)，由沈(shen)陽機床(chuang)精度(du)查(cha)驗規(gui)范(fan)斷定），放置主(zhu)軸180°使千(qian)分表觸(chu)頭(tou)再次觸(chu)及滑(hua)塊的(de)(de)旁(pang)邊(bian)面(mian)上(shang)查(cha)驗。千(qian)分表兩次讀(du)數的(de)(de)較(jiao)大(da)差(cha)(cha)值即是筆直度(du)差(cha)(cha)錯。

依據運用(yong)和規劃的(de)(de)(de)(de)需求，數(shu)控(kong)機(ji)床(chuang)的(de)(de)(de)(de)主(zhu)(zhu)軸(zhou)有各(ge)種不一(yi)樣(yang)的(de)(de)(de)(de)定心辦法(fa)，銷(xiao)售以確保工件或刀具在(zai)(zai)反(fan)轉時(shi)處于平穩狀(zhuang)況(kuang)，因(yin)而進口需求定心軸(zhou)頸的(de)(de)(de)(de)外表與主(zhu)(zhu)軸(zhou)反(fan)轉軸(zhou)線同軸(zhou)。檢查同軸(zhou)度(du)差錯的(de)(de)(de)(de)辦法(fa)也即是(shi)丈(zhang)量(liang)其徑(jing)向(xiang)(xiang)(xiang)(xiang)(xiang)和斜向(xiang)(xiang)(xiang)(xiang)(xiang)圓跳動差錯。將千(qian)分(fen)表（丈(zhang)量(liang)精度(du)需求高時(shi)選用(yong)測微儀）固定在(zai)(zai)機(ji)床(chuang)上，使千(qian)分(fen)表測頭頂在(zai)(zai)主(zhu)(zhu)軸(zhou)定心軸(zhou)頸外表上（若為錐(zhui)面，則測頭筆直于錐(zhui)面），旋(xuan)轉主(zhu)(zhu)軸(zhou)檢查。千(qian)分(fen)表讀數(shu)的(de)(de)(de)(de)較大差值，即是(shi)定心軸(zhou)頸徑(jing)向(xiang)(xiang)(xiang)(xiang)(xiang)和斜向(xiang)(xiang)(xiang)(xiang)(xiang)圓跳動差錯的(de)(de)(de)(de)數(shu)值。其丈(zhang)量(liang)方(fang)向(xiang)(xiang)(xiang)(xiang)(xiang)是(shi)被測面的(de)(de)(de)(de)方(fang)向(xiang)(xiang)(xiang)(xiang)(xiang)。
