絎(heng)(heng)磨(mo)管(guan)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝原(yuan)理絎(heng)(heng)磨(mo)管(guan)的(de)(de)(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)是采(cai)用滾壓(ya)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，珩(heng)磨(mo)管(guan)鋼管(guan)表(biao)(biao)面(mian)(mian)留有的(de)(de)(de)(de)應壓(ya)力(li)，對于表(biao)(biao)面(mian)(mian)微小裂紋有很好的(de)(de)(de)(de)封閉作(zuo)用，能(neng)防止表(biao)(biao)面(mian)(mian)受到(dao)侵蝕。從而(er)提高了表(biao)(biao)面(mian)(mian)的(de)(de)(de)(de)抗腐蝕能(neng)力(li)，并能(neng)減少(shao)(shao)裂紋的(de)(de)(de)(de)產(chan)生和擴大(da)，這樣加(jia)(jia)(jia)強(qiang)了絎(heng)(heng)磨(mo)管(guan)的(de)(de)(de)(de)抗壓(ya)強(qiang)度。通(tong)過滾壓(ya)成(cheng)型的(de)(de)(de)(de)絎(heng)(heng)磨(mo)管(guan)，能(neng)在(zai)表(biao)(biao)面(mian)(mian)形(xing)成(cheng)一層(ceng)冷作(zuo)硬化層(ceng)，減少(shao)(shao)磨(mo)削(xue)(xue)副接(jie)觸表(biao)(biao)面(mian)(mian)的(de)(de)(de)(de)彈性(xing)和塑性(xing)變形(xing)，從而(er)提高了耐磨(mo)性(xing)，避免(mian)因磨(mo)削(xue)(xue)產(chan)生的(de)(de)(de)(de)燒傷。滾壓(ya)后的(de)(de)(de)(de)表(biao)(biao)面(mian)(mian)粗糙度大(da)大(da)減小，提高了絎(heng)(heng)磨(mo)管(guan)的(de)(de)(de)(de)配(pei)合性(xing)。所謂(wei)滾壓(ya)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)是一種無切屑加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，在(zai)常溫(wen)下利(li)用金屬的(de)(de)(de)(de)塑性(xing)變形(xing)，使表(biao)(biao)面(mian)(mian)的(de)(de)(de)(de)不平(ping)整度碾(nian)平(ping)，從而(er)達到(dao)改變表(biao)(biao)面(mian)(mian)結(jie)構、機械特(te)性(xing)、性(xing)質(zhi)和尺寸(cun)的(de)(de)(de)(de)終目的(de)(de)(de)(de)。這種滾壓(ya)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)技術是磨(mo)削(xue)(xue)無法做到(dao)了，同時(shi)滿足(zu)光整加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)和強(qiang)化的(de)(de)(de)(de)要求。

珩磨(mo)(mo)管珩磨(mo)(mo)加工(gong)后(hou)表面質量好(hao)，有利于潤滑油(you)的(de)存儲及油(you)膜(mo)的(de)保持，有較(jiao)高(gao)的(de)表面支承率(lv)，因而能(neng)承受(shou)較(jiao)大載荷，耐磨(mo)(mo)損，從而提高(gao)了產品的(de)使用(yong)壽命；加工(gong)范圍廣，主要加工(gong)各種圓柱形孔，用(yong)專用(yong)珩磨(mo)(mo)頭還可(ke)加工(gong)圓錐(zhui)孔、橢圓孔等(deng)。加工(gong)精度(du)(du)高(gao)，特別(bie)是一(yi)些中(zhong)小型(xing)的(de)光(guang)通孔，其圓柱度(du)(du)可(ke)達 0.001mm以內。一(yi)些壁(bi)厚不均(jun)勻的(de)零件，其圓度(du)(du)能(neng)達 0.002mm。對于大孔，圓度(du)(du)也可(ke)達 0.005mm，珩磨(mo)(mo)比磨(mo)(mo)削加工(gong)精度(du)(du)高(gao)。
