在(zai)控制齿(chi)轮(lun)(lun)加(jia)(jia)(jia)工(gong)(gong)成本(ben)的(de)同(tong)时，如何实(shi)(shi)现高(gao)效(xiao)、高(gao)精度及高(gao)稳(wen)定性加(jia)(jia)(jia)工(gong)(gong)，我国(guo)汽(qi)车(che)(che)制造厂家竞(jing)(jing)相(xiang)竞(jing)(jing)争(zheng)的(de)动力及目(mu)标.汽(qi)车(che)(che)变速(su)箱(xiang)齿(chi)轮(lun)(lun)的(de)加(jia)(jia)(jia)工(gong)(gong)工(gong)(gong)艺主要(yao)分软齿(chi)面(mian)加(jia)(jia)(jia)工(gong)(gong)和硬(ying)(ying)齿(chi)面(mian)加(jia)(jia)(jia)工(gong)(gong)。软齿(chi)面(mian)加(jia)(jia)(jia)工(gong)(gong)一般采用滚齿(chi)→剃齿(chi)→热(re)处理(li)工(gong)(gong)艺，硬(ying)(ying)齿(chi)面(mian)加(jia)(jia)(jia)工(gong)(gong)采用滚齿(chi)→热(re)处理(li)(渗碳)→磨(mo)齿(chi)工(gong)(gong)艺。目(mu)前(qian)，针对汽(qi)车(che)(che)变速(su)箱(xiang)齿(chi)轮(lun)(lun)高(gao)效(xiao)、高(gao)精度及高(gao)稳(wen)定性加(jia)(jia)(jia)工(gong)(gong)要(yao)求，CBN刀片成功运用于(yu)大(da)齿(chi)轮(lun)(lun)硬(ying)(ying)齿(chi)面(mian)(HRC62)的(de)断续加(jia)(jia)(jia)工(gong)(gong)上，实(shi)(shi)现了以车(che)(che)削代替磨(mo)削工(gong)(gong)艺，大(da)大(da)提高(gao)了加(jia)(jia)(jia)工(gong)(gong)效(xiao)率，另外，东泰刀具(ju)在(zai)汽(qi)车(che)(che)齿(chi)轮(lun)(lun)渗碳淬火后端(duan)面(mian)、内孔、同(tong)步啮合(he)齿(chi)轮(lun)(lun)的(de)锥面(mian)精加(jia)(jia)(jia)工(gong)(gong)、齿(chi)轮(lun)(lun)轴(zhou)硬(ying)(ying)车(che)(che)切槽方面(mian)有新(xin)的(de)突破(po)，研发的(de)CBN整(zheng)体刀片在(zai)该领域成功运用，是目(mu)前(qian)技(ji)术水平(ping)较高(gao)的(de)齿(chi)轮(lun)(lun)加(jia)(jia)(jia)工(gong)(gong)刀具(ju)。

立方氮化硼刀片(pian)广泛应用(yong)于(yu)HRC50-HRC79之间齿轮(lun)渗碳(tan)(tan)淬(cui)火(huo)、铸(zhu)铁(tie)制动盘、空调(diao)制冷预缩机等(deng)工业，解决了(le)陶(tao)瓷刀片(pian)精(jing)车齿轮(lun)渗碳(tan)(tan)淬(cui)火(huo)件效(xiao)率低，成本高的(de)问(wen)题，片(pian)精(jing)车精(jing)度(du)(du)(du)差形位公差难以(yi)保证问(wen)题，而且CBN刀片(pian)耐用(yong)度(du)(du)(du)高，使用(yong)过程中大多(duo)属于(yu)正常磨损，出现崩刃、崩块的(de)现象较少，并在车削，铣削，镗(tang)削，切(qie)槽精(jing)车HRC45-HRC68之间高硬(ying)度(du)(du)(du)淬(cui)火(huo)件大有所为。

东泰刀(dao)(dao)具(ju)提供齿轮(lun)内孔和端面，齿轮(lun)轴、同轴器拨叉槽等部位的切(qie)削CBN刀(dao)(dao)具(ju)，也在不断创(chuang)新，改(gai)善CBN刀(dao)(dao)片的性能，使能满足更多(duo)用(yong)户的加(jia)工需求，向更大加(jia)工范围发展。
