Claims

[Claims for Utility Model Registration] A work head for holding a bevel gear, and a cutter for rotating and cutting the held bevel gear by a spindle shaft are provided, and the spindle shaft is moved up and down by rotation of a cam. In a gear cutting machine that is configured so that the cutter is moved up and down and the work head rotates one tooth at a time while the cutter is going up, the shape of the cam can be adjusted from the center of rotation to the outer circumference of the cam. By taking the maximum distance at two points near the rotation angle of 180° and around the rotation angle of 360°, the spindle shaft is formed to move up and down twice with one rotation of the cam, and is used for the first rough cutting. A gear cutting device for a bevel gear, characterized in that a chamfering tool moves forward after up-and-down to perform chamfering, and then performs a second up-and-down for finishing cutting.
