MACHINING TOOL Russian patent published in 2018 - IPC B23C5/10 B23C5/22 B23B27/16 

FIELD: instrument engineering.

SUBSTANCE: invention relates to tools for machining materials. Tool has major part having at least one socket for fastening cutting insert by means of fixing screw. Socket has lower surface on which lower part of cutting insert rests, and side bearing surface. On bottom surface of socket, channel for placing fixing screw is formed, having threaded portion and a threadless portion closer to socket bottom surface. Cutting insert is fixed in socket in such a way that head part of fixing screw is supported in through hole in cutting insert, threaded part of fixing screw is in cooperation with threaded part of channel. In this case, fixing screw is elastically bent so that its rod-shaped threadless part rests on threadless part of channel on the side, which is remote from the side bearing surface, and is located at a distance from threadless part of channel on side facing side bearing surface.

EFFECT: reliable and precise positioning of cutting inserts and efficient chip removal is ensured.
