PROBLEM TO BE SOLVED: To provide a gear machining apparatus by which a machining tool and a workpiece are synchronously rotated at a high speed to be capable of performing gear machining by cutting with high machining accuracy.SOLUTION: Number of tool blades of a machining tool 42 is equivalent to integral divisions of tooth number of a gear to be processed or integral multiples thereof so that one tooth of the gear to be processed is cut by an identical tool blade or a plurality of identical tool blades. Only shape error of the identical tool blade or the plurality of identical tool blades is transferred to one tooth, thereby a tooth trace error of the tooth is improved. |
