　　鋼軌鉆(zhan)頭

　　鋼軌鉆(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)分(fen)為高速鋼系(xi)列和硬質(zhi)合金(jin)(jin)系(xi)列，是與鋼軌鉆(zhan)(zhan)(zhan)(zhan)(zhan)孔(kong)機配(pei)套使用(yong)(yong)，是鐵(tie)路養護(hu)維(wei)修(xiu)(xiu)的必備鉆(zhan)(zhan)(zhan)(zhan)(zhan)孔(kong)刀(dao)(dao)具，其(qi)特點(dian)采用(yong)(yong)多個切削刃，耐磨(mo)(mo)性能(neng)好、鉆(zhan)(zhan)(zhan)(zhan)(zhan)孔(kong)精度(du)高、鉆(zhan)(zhan)(zhan)(zhan)(zhan)孔(kong)效率比普通麻花鉆(zhan)(zhan)(zhan)(zhan)(zhan)成(cheng)倍提高。一(yi)(yi)支鉆(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)一(yi)(yi)次(ci)可在比較(jiao)硬材質(zhi)的鋼軌上鉆(zhan)(zhan)(zhan)(zhan)(zhan)孔(kong)40-50個孔(kong)，且鉆(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)磨(mo)(mo)損后(hou)可連(lian)續修(xiu)(xiu)磨(mo)(mo)十(shi)多次(ci);另(ling)一(yi)(yi)種硬質(zhi)合金(jin)(jin)鋼軌鉆(zhan)(zhan)(zhan)(zhan)(zhan)，鉆(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)采用(yong)(yong)高強度(du)硬質(zhi)合金(jin)(jin)刀(dao)(dao)片焊接而成(cheng)，鉆(zhan)(zhan)(zhan)(zhan)(zhan)孔(kong)壽(shou)命長(chang)、刀(dao)(dao)片不(bu)宜磨(mo)(mo)損，鉆(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)不(bu)宜斷裂(lie)等優點(dian)，并(bing)且磨(mo)(mo)損后(hou)也(ye)可修(xiu)(xiu)磨(mo)(mo)數次(ci)。
