CUTTING PLATE Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: cutting edges of the plate have two smoothly conjugated segments. The segment are inclined toward each other. Being mounted on a cutting tool, the axial front angle of the segment of the cutting edge abutting against the operating top is in the range of 4°-30° and greater than the axial front angle abutting against the nonoperating top of the segment of the cutting edge that is in the range of ± 15^°. The projection of the segment of the cutting edge abutting against the operating top on the axis of the cutting tool is 0.6-0.9 of the projection of all cutting edge on the axis. The segments of the cutting edge are arranged on the rotation surface, the axis of which is coincident with the axis of the cutting tool and which forms a straight line at intersection with the axial plane of the cutting tool. EFFECT: enhanced reliability. 10 cl, 8 dwg
