在单件小批生产或修配中,往往遇到些锥形孔的加工(如定位销锥孔等),而且锥形孔的锥度大小也各不相同。一般工厂不可能具备各种锥形铰刀,在此情况下,可用普通麻花钻头制作锥形钻头,以代替各种锥铰刀,效果较好。其方法是根据工件锥孔的要求,按锥孔大端直径D选好钻头(尽量选用较短的),而后在外圆磨床上磨出锥度。为
In a single small batch production or repair, often encounter some tapered hole processing (such as the positioning pin taper hole, etc.), and taper hole taper size varies. General factory can not have a variety of tapered reamer, in this case, the general twist drill bit can be used to make conical drill instead of various cone reamer, the better. The method is based on the requirements of the workpiece taper hole, according to the cone end diameter D selection of the drill (try to use shorter), and then grinding cylindrical grinding machine taper. for
