CUTTER WITH VARIABLE FRONT ANGLE Russian patent published in 2021 - IPC B23B27/16 

FIELD: technological processes.

SUBSTANCE: cutter comprises a holder, a rotary cutting head with a cutting plate fixed on it, made with possibility of contacting with the holder along a cylindrical surface, the axis of which passes along the main cutting edge of the cutting plate, and fastening elements. Cutter is equipped with linear electric microdrive, carriage of which is connected to rotary cutting head through rotary lever, wherein the base of the linear electric micro drive is fixed on the holder by means of a tuning screw, and said fasteners are made in form of circular rolling guides with axis of rotation, which coincides with rotary cutting head axis, and installed on its end surfaces.

EFFECT: increased resistance of cutter and quality of machined surface due to operative change of its front kinematic angle in compliance with change of cutting conditions and acting on it moment of cutting forces.
