CUTTING ELEMENT FOR MACHINING SHAPED SURFACES BY ROTATIONAL TURNING

摘要

The utility model relates to the field of machining materials by cutting and can be used for machining helical surfaces by rotational turning; the utility model solves the problem of broadening the technological capabilities of a cutting tool during rotational turning. A seating surface is pressed against a mating surface of the shaft of a rotating cutting tool via a central stepped cylindrical bore; during cutting, a cutting edge removes the machined material while constantly rotating under the effect of the cutting force owing to the presence of an angle of inclination of the cutting edge; the curved shape of a side surface makes it possible to achieve smaller sizes of the shaped surface profile and widens the range of product dimension types; due to the presence of a groove, a top surface provides for better chip removal, thus improving the cutting process when machining hard-to-cut materials.
