を特徴とするものである。Moreover, the gear cutting method of the present invention using this gear cutting cutter is as follows:
The tooth width direction of the gear cutter having a uniform tooth profile along the face width direction and the face width direction of the workpiece are tilted, and the gear cutter is made to perform cutting movement in the face width direction of the workpiece. It is something to do.
〈作 用〉
歯切りカッタの歯幅方向とワークの歯幅方向とを傾けた
状態で歯切りカッタをワークの歯幅方向に切削運動させ
ると、歯切りカッタの切刃の部分のみがワークに当接し
、歯切りカッタの歯形をその歯幅方向に沿って均一化し
たことによる切れ味の低下が防止される。<Operation> When the tooth width direction of the gear cutter and the workpiece face width direction are tilted and the gear cutter is moved in the face width direction of the workpiece, only the cutting edge portion of the gear cutter touches the workpiece. This prevents deterioration in sharpness due to the tooth profile of the gear cutter being made uniform along the tooth width direction.
又、歯切りカッタを歯車やラックと同一歯形に設定でき
る。Additionally, the gear cutter can be set to have the same tooth profile as the gear or rack.

A pinion cutter 12 is attached to the tip of a spindle 18 that rotates synchronously with the work table 15. As a result, work 16
Tilt the tooth width direction of the pinion cutter 12 and the tooth width direction of the pinion cutter 12,
When reciprocating the spindle 18 in a direction parallel to its axis, the spindle head 19 is shifted in a direction perpendicular to this or in a direction perpendicular to the axis of the workpiece 16, and the pinion cutter 12 moves the axis of the workpiece 16. Give the spindle 18 a composite motion that causes it to reciprocate in a direction parallel to .
