ASSEMBLED CUTTER Russian patent published in 2021 - IPC B23B27/16 

FIELD: cutting.

SUBSTANCE: assembled cutter comprises a holder, installed in the socket whereof is a cutting plate fixed by a mounting screw installed in the holder. The cutting plate therein has a main and auxiliary cutting edges connected by a radius section at the top, and is defined by an upper surface whereon the front surface is located and a lower support surface parallel to the upper surface, wherein a side surface with rear surfaces adjacent to said main and auxiliary cutting edges and radius section is located between said surfaces. The socket of the holder is defined by the lower support wall for interaction with the lower support surface of the cutting plate and two side support walls. A mounting part is made on the cutting plate, including an upper side support surface adjacent to the upper surface, located at an acute angle to the lower support surface, at an acute angle to the main cutting edge in the top view of the cutting plate, and configured to interact with one of the side support walls of the socket of the holder, a lower side support surface adjacent to the lower support surface, located at an obtuse angle to the main cutting edge in the top view of the cutting plate and configured to interact with the other side support wall of the socket of the holder, and an intermediate section located between said upper side support surface and lower side support surface and provided with a through hole the axis whereof is perpendicular to the lower support surface, wherein a conical section is made in said hole for interaction with the conical section made on the mounting screw.

EFFECT: increase in the accuracy of processing is achieved.
