INTERNAL-GEAR MACHINING DEVICE AND INTERNAL-GEAR MACHINING METHOD

摘要

Provided is an internal gear processing machine and an internal gear processing method capable of performing high precision machining by removing an inclination angle generated in a cutter rotation axis by using an existing configuration. Therefore, in the internal gear machining machine in which the work W is gear-cut by the pinion cutter 17 by giving the cutting and the conveyance to the pinion cutter 17 while synchronously rotating the pinion cutter 17 and the work W The pinion cutter 17 is arranged so that the cutter rotary shaft B moves in parallel in the XY plane in accordance with the tilt angle phi of the cutter rotary shaft B prior to gear cutting, W is shifted in the main direction of the cutter.
