摘要： Provided is a gear processing machine which has a simple configuration, and is capable of processing a gear with high accuracy. For this purpose, a gear grinding machine wherein a tooth alignment operation is performed prior to grinding, is equipped with a workpiece processing rotation shaft (22) which rotates a workpiece (W1) located at a workpiece processing position (P2) ; a workpiece swing device (30) whereby a tailstock (50) that holds the workpiece (W1) is swung between a workpiece replacement position (P1) and a workpiece processing position (P2) ; a workpiece alignment rotation shaft (52) which rotates the workpiece (W1) held by the tailstock (50); and a tooth alignment sensor (43) that detects the rotation phase of the workpiece (W1), which was rotated by the workpiece alignment rotation shaft (52). Before the workpiece (W1) held by the tailstock (50) is placed at the workpiece processing position (P2), the rotation of the workpiece alignment rotation shaft (52) is controlled on the basis of the rotation phase detected, so that the workpiece (W1) will engage with a threaded grinding stone (16).

摘要： PROBLEM TO BE SOLVED: To provide a compact gear grinder including an easy-to-replace grinding wheel. SOLUTION: The gear grinder grinds a workpiece W by mutually rotating the workpiece W and the grinding wheel 17 meshed with each other. The gear grinder includes a rotary table 22 rotating around a workpiece rotating axis C while holding the workpiece W, and a turntable 31 supported turnably around the workpiece rotating axis C. A grinding wheel receiving base 50 where the grindstone 17 is placed is arranged on the turntable 31. The grinding wheel receiving base 50 is moved between a grindstone replacing position G1 and a grindstone carry-in/out position G2 by turning the turntable 31. COPYRIGHT: (C)2012,JPO&INPIT
