近來(lai)，在(zai)第(di)十四(si)屆(jie)我國國際(ji)機(ji)床(chuang)(chuang)(chuang)展新聞發布會上，我國機(ji)床(chuang)(chuang)(chuang)東西協會負責(ze)人(ren)直言(yan)，2014年機(ji)床(chuang)(chuang)(chuang)東西職(zhi)(zhi)業承壓運轉，下行(xing)壓力進一(yi)(yi)步加大，上一(yi)(yi)年是(shi)(shi)十幾(ji)年來(lai)職(zhi)(zhi)業最難熬的低(di)谷。數據(ju)顯(xian)現，僅(jin)2014年12月(yue)，全職(zhi)(zhi)業虧損公(gong)司占(zhan)比31.9%，其(qi)間，金切機(ji)床(chuang)(chuang)(chuang)更是(shi)(shi)高(gao)(gao)達(da)42.7%。機(ji)床(chuang)(chuang)(chuang)職(zhi)(zhi)業結構水平低(di)，“高(gao)(gao)端失守，低(di)端混戰”，機(ji)床(chuang)(chuang)(chuang)銷售是(shi)(shi)形成公(gong)司虧損的首要(yao)原因。

東北橫(heng)梁(liang)(liang)移(yi)(yi)動時傾(qing)斜(xie)度差(cha)錯的檢查(cha)辦法，在橫(heng)梁(liang)(liang)導軌的基(ji)地方位，平行于橫(heng)梁(liang)(liang)放置一(yi)個(ge)(ge)水平儀。移(yi)(yi)動橫(heng)梁(liang)(liang)，每隔500mm（或小于500mm）記(ji)載(zai)一(yi)次讀數，在橫(heng)梁(liang)(liang)悉數行程(cheng)上至少記(ji)載(zai)3個(ge)(ge)讀數。在橫(heng)梁(liang)(liang)悉數行程(cheng)上檢查(cha)時，兩(liang)筆直(zhi)刀架(jia)（或銑頭）應移(yi)(yi)到橫(heng)梁(liang)(liang)上相對稱的方位。而橫(heng)梁(liang)(liang)的移(yi)(yi)動方向，只(zhi)能(neng)由下(xia)往上，不能(neng)往復(fu)。這種辦法多用于龍門刨(bao)床(chuang)、數控(kong)銑床(chuang)、立式車床(chuang)等橫(heng)梁(liang)(liang)移(yi)(yi)動時的傾(qing)斜(xie)度差(cha)錯的檢查(cha)。
