珩磨機(ji):

       利用珩磨頭珩磨工(gong)(gong)件(jian)精(jing)加工(gong)(gong)表(biao)面的磨床。主要用在汽(qi)車、拖拉機、液壓件(jian)、軸承、航空等制造(zao)業中珩磨工(gong)(gong)件(jian)的孔。珩磨機有立式和(he)臥式兩種。

不同類(lei)別(bie)及特(te)點:

       立式(shi)(shi)珩(heng)(heng)磨(mo)(mo)(mo)(mo)機的(de)主(zhu)(zhu)軸(zhou)工(gong)作(zuo)行程(cheng)較短，適用于珩(heng)(heng)磨(mo)(mo)(mo)(mo)缸體和箱體孔等(deng)。鑲嵌有(you)油石的(de)珩(heng)(heng)磨(mo)(mo)(mo)(mo)頭(tou)由豎直安置(zhi)的(de)主(zhu)(zhu)軸(zhou)帶(dai)動旋(xuan)轉(zhuan)，同時在液壓(ya)裝(zhuang)置(zhi)的(de)驅(qu)動下(xia)作(zuo)垂直往復進給運(yun)動(見(jian)機床)。臥式(shi)(shi)珩(heng)(heng)磨(mo)(mo)(mo)(mo)機的(de)工(gong)作(zuo)行程(cheng)較長(chang)，適用于珩(heng)(heng)磨(mo)(mo)(mo)(mo)深孔，深度可達3000毫米。水平(ping)安置(zhi)的(de)珩(heng)(heng)磨(mo)(mo)(mo)(mo)頭(tou)不旋(xuan)轉(zhuan)，只作(zuo)軸(zhou)向(xiang)往復運(yun)動，工(gong)件由主(zhu)(zhu)軸(zhou)帶(dai)動旋(xuan)轉(zhuan)，床身中部設有(you)支承(cheng)(cheng)工(gong)件的(de)中心架和支承(cheng)(cheng)珩(heng)(heng)磨(mo)(mo)(mo)(mo)桿的(de)導向(xiang)架。在加工(gong)過(guo)程(cheng)中，珩(heng)(heng)磨(mo)(mo)(mo)(mo)頭(tou)的(de)油石在脹縮機構作(zuo)用下(xia)作(zuo)徑向(xiang)進給，把工(gong)件逐(zhu)步加工(gong)到所需尺寸。新型(xing)的(de)珩(heng)(heng)磨(mo)(mo)(mo)(mo)機多采用液壓(ya)脹縮的(de)珩(heng)(heng)磨(mo)(mo)(mo)(mo)頭(tou)。珩(heng)(heng)磨(mo)(mo)(mo)(mo)機大(da)多是半自(zi)動的(de)，常(chang)帶(dai)有(you)自(zi)動測(ce)量裝(zhuang)置(zhi),還(huan)可納入(ru)自(zi)動生產線(xian)工(gong)作(zuo)。除加工(gong)孔的(de)珩(heng)(heng)磨(mo)(mo)(mo)(mo)機外,還(huan)有(you)加工(gong)其他(ta)表面(mian)(mian)的(de)外圓珩(heng)(heng)磨(mo)(mo)(mo)(mo)機、軸(zhou)承(cheng)(cheng)滾道珩(heng)(heng)磨(mo)(mo)(mo)(mo)機、平(ping)面(mian)(mian)珩(heng)(heng)磨(mo)(mo)(mo)(mo)機和曲面(mian)(mian)珩(heng)(heng)磨(mo)(mo)(mo)(mo)機等(deng)。
