ABSTRACT:
An internal gear shaving machine1which brings a shaving cutter3and an internal gear held by a workpiece chuck2into engagement with a crossed axes angle, and subjects the tooth flanks of the internal gear to final machining while it rotationally drives at least one of the shaving cutter3and the workpiece chuck2. The workpiece chuck2and shaving cutter3are supported movably toward and away from each other in a vertical direction with the workpiece chuck2higher and supported movably in the horizontal direction relative to each other. The workpiece chuck3is constituted to hold the outer circumferential surface of the internal gear with the axis of rotation of the internal gear oriented in a up-down direction so that shavings produced during processing by the shaving cutter can fall downwardly from the internal gear.
