摘要： PROBLEM TO BE SOLVED: To provide a roughing helical broach which can reduce a difference in cutting property between an acute angle side and an obtuse angle side. SOLUTION: In the roughing helical broach 1, a cutting edge part 30 includes n spline teeth 31 arranged along an axial direction. The cutting edges 32 of the spline teeth 31 are respectively arranged along desired helix angles and have acute angle parts and obtuse angle parts at both sides in the circumferential direction of the cutting edges 32. The cutting edges 32 (S 1 to S n-1 ) respectively arranged in the circumferential direction of the first to the (n-1)th spline teeth 31 (S 1 to S n-1 ) are formed to have different heights between the acute angle side and the obtuse angle side. Besides, the cutting edges 32 (Sn) of the (n)th spline teeth (Sn) are respectively formed to have a constant height in the circumferential direction. COPYRIGHT: (C)2010,JPO&INPIT

SOLUTION: The broach 19 is provided with a cemented carbide body 1; a front grip part 5 integrally provided at the cemented carbide body 1; a cylindrical part 34 following the front grip part 5 and provided with a plurality of guide parts 33 at the outer periphery; a broach cutting edge part 36 following a cylindrical end part 35 and provided with a large number of cutting edges 2; and a cylindrical extension part 12 following the broach cutting edge part 36 and having a maximum outer peripheral part within the limit of not interfering with the workpiece. The end face of the cylindrical extension part 12 is provided with a load receiving shoulder face 3 orthogonal to a broach axis or inclined to reach a rear grip part 11 including a small diameter part. The load receiving shoulder face 3 has an area large enough to support cutting load. A load receiving face 15 of a broaching machine is allowed to abut on the load receiving shoulder face 3 of the cemented carbide broach 19 to grip the rear grip part 11. COPYRIGHT: (C)2005,JPO&NCIPI

Between the round blades 10 adjacent in the axial line O direction in the round blade group 9, cutting grooves 12 extending along the peripheral direction around the axial line O on an outer periphery of the broach body 2 are formed. The cutting grooves 12 extend in a gradually twisted state toward the axial line O direction as going toward the peripheral direction. The spline blade group 7 and the round blade group 9 are formed integrally with the outer periphery of the broach body 2.
