Zusammenfassung:	A gear machining machine has a cutter head with improved rigidity. The machine is equipped with a movement base that is movably supported and rotatably supports a rotation table on which an external gear or an internal gear is mounted; a bridge section of a gate-shaped column provided at a location above the movement base; a saddle which is supported by the bridge section in a vertically movable manner; and a cutter head on the front surface of the saddle, the lower end of which rotatably supports a tool. A protrusion which projects forward is provided on the front surface of the cutter head. The tool is disposed so that the front thereof protrudes further forward of an end surface which is the most forward projecting portion of the protrusion.
