珩磨機:

 利用珩(heng)(heng)(heng)磨(mo)(mo)頭珩(heng)(heng)(heng)磨(mo)(mo)工件精加工表面的(de)(de)磨(mo)(mo)床。主要用在(zai)汽(qi)車、拖拉機(ji)、液壓件、軸承、航空等制造業中珩(heng)(heng)(heng)磨(mo)(mo)工件的(de)(de)孔。珩(heng)(heng)(heng)磨(mo)(mo)機(ji)有立式(shi)和(he)臥式(shi)兩種(zhong)。

不同類別及特點:

 立式珩(heng)(heng)(heng)磨(mo)(mo)機(ji)(ji)(ji)(ji)的(de)(de)主(zhu)軸工(gong)(gong)作(zuo)行程(cheng)較(jiao)(jiao)短，適用(yong)于珩(heng)(heng)(heng)磨(mo)(mo)缸體(ti)(ti)和箱體(ti)(ti)孔(kong)(kong)等(deng)。鑲嵌有油(you)石的(de)(de)珩(heng)(heng)(heng)磨(mo)(mo)頭(tou)(tou)由(you)豎直(zhi)(zhi)安置的(de)(de)主(zhu)軸帶(dai)(dai)動旋轉，同時(shi)在液壓(ya)裝置的(de)(de)驅動下作(zuo)垂直(zhi)(zhi)往(wang)復(fu)進給運動(見機(ji)(ji)(ji)(ji)床)。臥式珩(heng)(heng)(heng)磨(mo)(mo)機(ji)(ji)(ji)(ji)的(de)(de)工(gong)(gong)作(zuo)行程(cheng)較(jiao)(jiao)長，適用(yong)于珩(heng)(heng)(heng)磨(mo)(mo)深孔(kong)(kong)，深度可(ke)達3000毫(hao)米(mi)。水平(ping)安置的(de)(de)珩(heng)(heng)(heng)磨(mo)(mo)頭(tou)(tou)不旋轉，只作(zuo)軸向往(wang)復(fu)運動，工(gong)(gong)件(jian)由(you)主(zhu)軸帶(dai)(dai)動旋轉，床身中部設有支承(cheng)工(gong)(gong)件(jian)的(de)(de)中心架和支承(cheng)珩(heng)(heng)(heng)磨(mo)(mo)桿的(de)(de)導向架。在加(jia)工(gong)(gong)過程(cheng)中，珩(heng)(heng)(heng)磨(mo)(mo)頭(tou)(tou)的(de)(de)油(you)石在脹縮機(ji)(ji)(ji)(ji)構作(zuo)用(yong)下作(zuo)徑向進給，把工(gong)(gong)件(jian)逐(zhu)步(bu)加(jia)工(gong)(gong)到所(suo)需尺(chi)寸。新(xin)型的(de)(de)珩(heng)(heng)(heng)磨(mo)(mo)機(ji)(ji)(ji)(ji)多采用(yong)液壓(ya)脹縮的(de)(de)珩(heng)(heng)(heng)磨(mo)(mo)頭(tou)(tou)。珩(heng)(heng)(heng)磨(mo)(mo)機(ji)(ji)(ji)(ji)大多是半自動的(de)(de)，常帶(dai)(dai)有自動測量裝置,還可(ke)納入自動生(sheng)產線(xian)工(gong)(gong)作(zuo)。除(chu)加(jia)工(gong)(gong)孔(kong)(kong)的(de)(de)珩(heng)(heng)(heng)磨(mo)(mo)機(ji)(ji)(ji)(ji)外,還有加(jia)工(gong)(gong)其(qi)他表面的(de)(de)外圓珩(heng)(heng)(heng)磨(mo)(mo)機(ji)(ji)(ji)(ji)、軸承(cheng)滾道珩(heng)(heng)(heng)磨(mo)(mo)機(ji)(ji)(ji)(ji)、平(ping)面珩(heng)(heng)(heng)磨(mo)(mo)機(ji)(ji)(ji)(ji)和曲面珩(heng)(heng)(heng)磨(mo)(mo)機(ji)(ji)(ji)(ji)等(deng)。
