JPS6451224A - Shaving cutter for removing burr at end surface - Google Patents

Abstract

PURPOSE:To make it possible to cut only burrs at a tooth end surface without cutting the tooth body by gearing and pressing a group train of cutting edges to a gear tooth, rotating a cutter by the rotation of a work, and sliding and moving relatively the cutting edge surface and gearing tooth. CONSTITUTION:On condition that a cutting edge group train 12 are engaged with a gearing tooth 4, a cutter main body 8 is arranged pressing to the inner surface of a work 2, and a shaving cutter 1 is made to move following the torque of the work 2. And by rotating the work 2 clockwise around the axis 11 of a rotary shaft, the cutter 1 receives the torque of the work 2 by the gearing of the edge group train 12 and the tooth 4 and rotates passively while changing the relative position with the work 2 clockwise. And, since the edge face 19 of the cutting edge is inclined at the angle theta to the tooth 4 of the work 2, when the cutter 1 rotates passively, each edge face 19 moves rubbing relatively with the tooth 4 at the crossing angle theta along the rotation axis 11 of the work 2. In this case, the burrs 6 generated at the end surface 20 of the tooth 4 can be cut and removed by the cutting edge 9.
