我公司是一家(jia)從事拉(la)床加工、拉(la)刀(dao)(dao)研(yan)磨的(de)企業，拉(la)削范圍(wei)主要(yao)有：真圓、D型(xing)、腰(yao)型(xing)、異型(xing)、齒型(xing)、多邊型(xing)、栓槽、鍵槽等。磨刀(dao)(dao)范圍(wei)主要(yao)有：圓拉(la)刀(dao)(dao)、平(ping)面(mian)拉(la)刀(dao)(dao)

加(jia)工鍵(jian)槽(cao)(cao)(cao)(cao)的方法分為軸(zhou)上(shang)加(jia)工鍵(jian)槽(cao)(cao)(cao)(cao)，lun盤鍵(jian)槽(cao)(cao)(cao)(cao)。軸(zhou)上(shang)加(jia)工鍵(jian)槽(cao)(cao)(cao)(cao)，只(zhi)能采用鍵(jian)槽(cao)(cao)(cao)(cao)銑(xian)刀銑(xian)鍵(jian)槽(cao)(cao)(cao)(cao)，lun盤類的零(ling)件加(jia)工鍵(jian)槽(cao)(cao)(cao)(cao)，可(ke)以采用插床插鍵(jian)槽(cao)(cao)(cao)(cao)、線切割切鍵(jian)槽(cao)(cao)(cao)(cao)、鉗工銼(cuo)修鍵(jian)槽(cao)(cao)(cao)(cao)。加(jia)工鍵(jian)槽(cao)(cao)(cao)(cao)應注意的是(shi)同(tong)軸(zhou)度、對稱度，加(jia)工，鍵(jian)槽(cao)(cao)(cao)(cao)深一些問題不大，E型孔(kong)加(jia)工，但(dan)是(shi)鍵(jian)槽(cao)(cao)(cao)(cao)的寬度尺(chi)寸一定要保證(zheng)，不能寬度尺(chi)寸不能大了。

我公司是一家從事拉(la)床加(jia)工(gong)、拉(la)刀研磨(mo)(mo)的企業，拉(la)削范(fan)(fan)圍主(zhu)要(yao)有：真圓、D型、腰型、異(yi)型、齒型、多邊型、栓槽、鍵槽等。磨(mo)(mo)刀范(fan)(fan)圍主(zhu)要(yao)有：圓拉(la)刀、平面(mian)拉(la)刀

常(chang)用的圓孔拉刀，組成部分有

（1）切削部 ? ?承擔全(quan)部余量的切除工作(zuo)，由粗(cu)切齒、過渡齒和精(jing)切齒組成(cheng)。

（2）校(xiao)準部 ? ?用(yong)以校(xiao)正孔徑，修光孔壁，并(bing)作為精(jing)切齒的后備齒

（3）后導部(bu) ? ?用(yong)以保持(chi)拉(la)刀(dao)后正確(que)位置，防止拉(la)刀(dao)在即將離開工(gong)(gong)件(jian)(jian)時，拉(la)刀(dao)加(jia)工(gong)(gong)，工(gong)(gong)件(jian)(jian)下垂(chui)而損壞已加(jia)工(gong)(gong)表面或刀(dao)齒。

（4）后柄 ? ?用(yong)作直(zhi)徑大(da)于60mm既長又(you)重拉刀(dao)的后支承，栓槽(cao)加工，防止拉刀(dao)下垂。直(zhi)徑較(jiao)小的拉刀(dao)可不設后柄。

我(wo)公司是一(yi)家(jia)從事拉床加(jia)工、拉刀研磨的企業，拉削范圍主要有：真圓、D型(xing)、腰型(xing)、異型(xing)、齒型(xing)、多(duo)邊型(xing)、栓槽、鍵(jian)槽等(deng)。磨刀范圍主要有：圓拉刀、平(ping)面(mian)拉刀

花鍵加工工藝

目(mu)前外花(hua)(hua)(hua)鍵(jian)(jian)(jian)(jian)主要采用(yong)花(hua)(hua)(hua)鍵(jian)(jian)(jian)(jian)銑削加工(gong)(gong)，精度(du)較高或有螺旋角要求的鍵(jian)(jian)(jian)(jian)齒(chi)也(ye)(ye)(ye)采用(yong)滾齒(chi)機(ji)加工(gong)(gong)，如(ru)汽車(che)(che)變速(su)器(qi)輸入軸花(hua)(hua)(hua)鍵(jian)(jian)(jian)(jian)和重型卡車(che)(che)后橋減速(su)器(qi)主動錐齒(chi)輪(lun)花(hua)(hua)(hua)鍵(jian)(jian)(jian)(jian)。外花(hua)(hua)(hua)鍵(jian)(jian)(jian)(jian)也(ye)(ye)(ye)可采用(yong)插削加工(gong)(gong)，如(ru)重型卡車(che)(che)變速(su)器(qi)輸出(chu)軸花(hua)(hua)(hua)鍵(jian)(jian)(jian)(jian)。小模數外花(hua)(hua)(hua)鍵(jian)(jian)(jian)(jian)的無(wu)屑加工(gong)(gong)做為新工(gong)(gong)藝也(ye)(ye)(ye)逐(zhu)步得到(dao)認可。常用(yong)的花(hua)(hua)(hua)鍵(jian)(jian)(jian)(jian)無(wu)屑加工(gong)(gong)有冷(leng)擠壓、冷(leng)軋等，特點是加工(gong)(gong)效率l高，有助于(yu)提高花(hua)(hua)(hua)鍵(jian)(jian)(jian)(jian)的強度(du)，如(ru)汽車(che)(che)半軸花(hua)(hua)(hua)鍵(jian)(jian)(jian)(jian)，凸輪(lun)軸花(hua)(hua)(hua)鍵(jian)(jian)(jian)(jian)等。
