CUTTING PLATE AND CUTTING TOOL WITH CUTTING PLATE INSTALLED ON IT Russian patent published in 2024 - IPC B23C5/20 B23C5/06 

FIELD: machine building.

SUBSTANCE: group of inventions relates to a cutting plate and a cutting tool equipped with it. Double-sided cutting plate has an upper surface, a lower surface, a side surface, a cutting edge and a mounting hole passing through the upper surface and the lower surface. Upper surface is provided with one protruding part of the upper surface, which surrounds the mounting hole and is flat. Cutting edge comprises a major cutting edge, an angular cutting edge extending from the major cutting edge, an auxiliary cutting edge extending from the angular cutting edge and a side portion extending from the auxiliary cutting edge. First side surface of the main cutting edge, passing from the main cutting edge, forms an acute angle with the line of continuation of the projecting part of the upper surface. Chip breaking surface of auxiliary cutting edge, passing from auxiliary cutting edge, is located at a gradually increasing angle to the extension line of the protruding part of the upper surface as the chip breaker surface of the auxiliary cutting edge moves away from the angular cutting edge, and when viewing the cutting plate from the upper surface, the surface of the side part extending from the side part is concave-recessed.

EFFECT: invention ensures elimination of chip jamming during chip formation.
