珩磨(mo)機:

       利用(yong)珩(heng)磨(mo)(mo)頭珩(heng)磨(mo)(mo)工件精加工表面(mian)的磨(mo)(mo)床。主要用(yong)在汽車、拖(tuo)拉(la)機(ji)(ji)、液壓件、軸承(cheng)、航空等制(zhi)造業中珩(heng)磨(mo)(mo)工件的孔。珩(heng)磨(mo)(mo)機(ji)(ji)有立式和(he)臥式兩種(zhong)。

不(bu)同類別及特點(dian):

       立式(shi)珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)機的主軸工(gong)(gong)作(zuo)行程較短，適(shi)用于珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)缸體(ti)和箱(xiang)體(ti)孔等。鑲嵌有油石(shi)的珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)頭(tou)由豎(shu)直安(an)置(zhi)(zhi)(zhi)的主軸帶(dai)動(dong)旋轉(zhuan)(zhuan)(zhuan)，同時(shi)在(zai)液壓裝置(zhi)(zhi)(zhi)的驅動(dong)下作(zuo)垂直往(wang)復(fu)(fu)進(jin)給運動(dong)(見機床)。臥式(shi)珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)機的工(gong)(gong)作(zuo)行程較長(chang)，適(shi)用于珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)深孔，深度可(ke)達3000毫米。水(shui)平安(an)置(zhi)(zhi)(zhi)的珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)頭(tou)不旋轉(zhuan)(zhuan)(zhuan)，只(zhi)作(zuo)軸向(xiang)往(wang)復(fu)(fu)運動(dong)，工(gong)(gong)件(jian)(jian)由主軸帶(dai)動(dong)旋轉(zhuan)(zhuan)(zhuan)，床身中部設(she)有支(zhi)承工(gong)(gong)件(jian)(jian)的中心架(jia)和支(zhi)承珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)桿的導向(xiang)架(jia)。在(zai)加(jia)工(gong)(gong)過程中，珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)頭(tou)的油石(shi)在(zai)脹縮機構作(zuo)用下作(zuo)徑向(xiang)進(jin)給，把(ba)工(gong)(gong)件(jian)(jian)逐步加(jia)工(gong)(gong)到所(suo)需尺寸。新型的珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)機多采用液壓脹縮的珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)頭(tou)。珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)機大多是半(ban)自動(dong)的，常帶(dai)有自動(dong)測量裝置(zhi)(zhi)(zhi),還可(ke)納入自動(dong)生(sheng)產線(xian)工(gong)(gong)作(zuo)。除加(jia)工(gong)(gong)孔的珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)機外,還有加(jia)工(gong)(gong)其他表面的外圓珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)機、軸承滾道(dao)珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)機、平面珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)機和曲(qu)面珩(heng)(heng)(heng)(heng)(heng)(heng)磨(mo)(mo)機等。
