Abstract

PURPOSE: To make it possible to readily obtain a highly smooth surface by monolithically providing a burnishing member in the rear of a plurality of cutting edges so that burnishing can be performed simultaneously with broaching.
CONSTITUTION: The broach 3 is provided with a shaft part 4 and a plurality of cutting edges 5 arranged in series and monolithically with said shaft part 4. Each cutting edge 5 is formed into a cylindrical shape and provided with a rake angle γ and a relief angle α each having a necessary angle, on its peripheral part. In the rear of the plurality of cutting edges 5, a disc-shaped burnishing member 6 is provided for crushing or burnishing the unevenness of a bearing surface 2. Therefore, the periphery of the burnishing member 6 is formed into an angular shape, the front inclination angle θ1, with respect to the axial direction of the broach, being set to be 1W5°, and the rear inclination angle θ2 to be 1W15°. Said constitution permits the degree of roughness of the cut surface to be made smaller with exceeding ease and at low cost.
