ABSTRACT:
An apparatus manufactures a die for rolling an hourglass worm in improved processing accuracy. The apparatus includes a swing table swung, a movement table mounted on the swing table, and a workpiece shaft arranged on the movement table. The axis of a disk-shaped workpiece is perpendicular to a swing axis of the swing table. The workpiece includes a peripheral surface with a cross-section extending along the workpiece axis and defining an arc substantially identical to the arc of the root surface of the hourglass worm. The movement table is arranged so that the swing axis of the swing table extends through a center of curvature of the arc defined on the peripheral surface of the workpiece. A synchronization mechanism swings the swing table in synchronism with the rotation of the workpiece shaft.
