CUTTING TOOL Russian patent published in 2017 - IPC B23C5/20 B23B27/16 

FIELD: machine engineering.

SUBSTANCE: cutting tool contains a fastening unit for the cutting insert with a G-shaped stitch with a cylindrical guide part perpendicular to the axis of which the conical surface is made with a cylindrical recess at its base. Fastening-unfastening of the plate is carried out with a screw with an eccentric axial conical surface with a cylindrical groove at the base. When fixing the plate, the conical surfaces of the guide and the screw interact, while the reinforcement - the cylindrical groove of the guide and the cylindrical groove of the screw. The screw provides an axial movement of the sticking in two directions for a half-turn.

EFFECT: auxiliary time for resetting the cutting inserts is shortened.
