珩磨機:

       利用珩磨頭珩磨工件精加工表面的磨床。主要用在汽車、拖拉機、液壓件、軸承、航空等制造業中珩磨工件的孔。珩磨機有立式和臥式兩種。氣動活塞桿

不(bu)同類別及特點:

       立式(shi)珩(heng)(heng)(heng)(heng)磨(mo)(mo)機(ji)的(de)(de)(de)(de)主(zhu)軸工(gong)(gong)(gong)作(zuo)行程較(jiao)短，適用于(yu)珩(heng)(heng)(heng)(heng)磨(mo)(mo)缸體和(he)箱體孔等。鑲嵌有(you)(you)油(you)石的(de)(de)(de)(de)珩(heng)(heng)(heng)(heng)磨(mo)(mo)頭(tou)由(you)豎(shu)直安置(zhi)的(de)(de)(de)(de)主(zhu)軸帶(dai)動(dong)(dong)旋轉，同時在液壓裝(zhuang)置(zhi)的(de)(de)(de)(de)驅動(dong)(dong)下作(zuo)垂直往復進給運動(dong)(dong)(見機(ji)床)。臥式(shi)珩(heng)(heng)(heng)(heng)磨(mo)(mo)機(ji)的(de)(de)(de)(de)工(gong)(gong)(gong)作(zuo)行程較(jiao)長，適用于(yu)珩(heng)(heng)(heng)(heng)磨(mo)(mo)深(shen)(shen)孔，深(shen)(shen)度可達(da)3000毫(hao)米。水平(ping)安置(zhi)的(de)(de)(de)(de)珩(heng)(heng)(heng)(heng)磨(mo)(mo)頭(tou)不旋轉，只作(zuo)軸向(xiang)往復運動(dong)(dong)，工(gong)(gong)(gong)件(jian)由(you)主(zhu)軸帶(dai)動(dong)(dong)旋轉，床身中部(bu)設有(you)(you)支承(cheng)工(gong)(gong)(gong)件(jian)的(de)(de)(de)(de)中心架和(he)支承(cheng)珩(heng)(heng)(heng)(heng)磨(mo)(mo)桿的(de)(de)(de)(de)導向(xiang)架。在加工(gong)(gong)(gong)過程中，珩(heng)(heng)(heng)(heng)磨(mo)(mo)頭(tou)的(de)(de)(de)(de)油(you)石在脹縮機(ji)構作(zuo)用下作(zuo)徑向(xiang)進給，把工(gong)(gong)(gong)件(jian)逐步加工(gong)(gong)(gong)到所需(xu)尺寸。新型(xing)的(de)(de)(de)(de)珩(heng)(heng)(heng)(heng)磨(mo)(mo)機(ji)多采用液壓脹縮的(de)(de)(de)(de)珩(heng)(heng)(heng)(heng)磨(mo)(mo)頭(tou)。珩(heng)(heng)(heng)(heng)磨(mo)(mo)機(ji)大多是(shi)半自(zi)動(dong)(dong)的(de)(de)(de)(de)，常(chang)帶(dai)有(you)(you)自(zi)動(dong)(dong)測(ce)量裝(zhuang)置(zhi),還可納(na)入(ru)自(zi)動(dong)(dong)生(sheng)產線工(gong)(gong)(gong)作(zuo)。除(chu)加工(gong)(gong)(gong)孔的(de)(de)(de)(de)珩(heng)(heng)(heng)(heng)磨(mo)(mo)機(ji)外,還有(you)(you)加工(gong)(gong)(gong)其他(ta)表面的(de)(de)(de)(de)外圓珩(heng)(heng)(heng)(heng)磨(mo)(mo)機(ji)、軸承(cheng)滾道珩(heng)(heng)(heng)(heng)磨(mo)(mo)機(ji)、平(ping)面珩(heng)(heng)(heng)(heng)磨(mo)(mo)機(ji)和(he)曲(qu)面珩(heng)(heng)(heng)(heng)磨(mo)(mo)機(ji)等。
