TL;DR: In this article, a gear shaping machine can form a plurality of engagement teeth on the outer peripheral surface of a portion in an axial direction of a workpiece with a shaft shape, and a lubricant feeding device 48 for injecting and feeding oil mist toward a cutting clearance between a flank 36a of the shaper blade 36 at cutting and a surface 22b to be cut from above the cutting clearance 46.
Abstract: PROBLEM TO BE SOLVED: To attain a desired smooth surface to be cut with sufficient accuracy even in a shaper blade repeatedly vertically moved at a relatively slow cutting speed when an outer peripheral surface of a portion in an axial direction of a workpiece with a shaft shape is cut by a gear shaping machine to form an engagement tooth. SOLUTION: The gear shaping machine can form a plurality of engagement teeth 5 on the outer peripheral surface of the portion 22a in the axial direction of the workpiece 22 in its circumferential direction in the state that an axis 4 of the workpiece 22 with the shaft shape is vertically directed. The gear shaping machine 1 is provided with the shaper blade 36 repeatedly vertically moved I, J and cutting the outer peripheral surface of the portion 22a of the workpiece 22 at descending movement to form the engagement tooth 5; and a lubricant feeding device 48 for injecting and feeding oil mist 47 toward a cutting clearance 46 between a flank 36a of the shaper blade 36 at cutting and a surface 22b to be cut from above the cutting clearance 46.
