| A plurality of cutting edges that are arranged on an outer circumference of a shaft-shaped broach body are provided with a spline teeth group, which contains a plurality of spline teeth 8 that groove a prepared hole of a work material, and a round teeth group, which is disposed in a different position from the spline teeth group along an axis direction and contains a plurality of round teeth that machine an inner circumference of the prepared hole. At least one gullet is formed to extend along the outer circumference of the broach body in a circumferential direction around the axis between the round teeth that are adjacent to one another in the axis direction in the round teeth group. The gullet extends toward the axis direction, gradually twisting toward the circumferential direction. The spline teeth group and the round teeth group are formed integrally on the outer circumference of the broach body. | ||||||

| A broaching machine having relatively reciprocable work and broach-supporting members comprising a pair of racks and pinions for effecting reciprocation of one member, a drive motor connected to a spline shaft, a pair of rigidly interconnected helical gears on said spline shaft, and gearing connecting each of said gears to one of said pinions so as to effect equal division of the load on each of said pinions.

| PROBLEM TO BE SOLVED: To provide a broach capable of enhancing process tolerance of cutting sufficiently.SOLUTION: Plural cutting blades 3 arranged in an outer periphery of an axial broach body 2 comprises: a spline blade group 7 including plural spline blades 8 for performing groove processing to a lower hole of a cut material; and a round blade group 9 arranged at a position different from that of the spline blade group 7 in an axial line O direction and including plural round blades 10 for performing inner peripheral processing to the lower hole. 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. | ||||||

| PURPOSE:To eliminate roughness due to the rest uncut and realize maintaining smoothness of the outer peripheral face of a rotor by forming one or more than two kerfs parallel with a rotary axis in the outer layer part. expected to be cut by a finishing edge, by means of a spare cutter edge positioned in front of the finishing edge. CONSTITUTION:When a set of broach 56, in a condition of fixing a cocoon-shaped rotor 40, is driven in the direction of an arrow, a kerf 66 is first formed on the outer peripheral face of the rotor 40 by means of a spare cutter edge 60 and, in continuation to this, the outer peripheral face, on which the kerf 66 is formed, is cut by means of a finishing edge 62. Then a finished face 70, with the same sectional form as that of a cutter edge 64, is formed on the outer peripheral face of the rotor 40, and a broad part is processed for finishing with high precision at once. Here, at the time of cutting by the finishing edge 62, the kerf 66 is already formed, and, since chips are divided, starting from the kerf 66, into small pieces with the same breadth as that of the interval between the kerfs 66 and roll individually, resistance to cutting by the finishing edge 62 is reduced to cause a slide 58 to move smoothly. This eliminates generation of exfoliation of the outer layer on the outer peripheral face of the rotor 40, and the surface can be finished smoothly. | ||||||
