BUILT-UP CUTTING TOOL (VERSIONS) Russian patent published in 2009 - IPC B23B27/16 

FIELD: instrument engineering.

SUBSTANCE: tool comprises a body in a pocket of which there is a cutter plate mounted and fixed, herewith provided with a polygonal or circular front face and intersected by flanks thereby forming cutting edges. The cutter plate has a lower and lateral bearing faces and the symmetry axis that intersects said faces. The lower bearing face is opposed to the front face. The lateral bearing faces lie on ledges equispaced around the symmetry axis under the cutter plate vertexes and turned therein. The tool is equipped with a body-mounted vibrator that interacts with a part of the lower bearing face of the cutter plate. Said part is placed on the ledge of the cutter plate under its noncutting vertex. In case the cutter plate has circular front face, the vibrator contacts the part of the lower bearing face of the cutter plate provided on the ledge of the cutter plate under the noncutting part of its cutting edge.

EFFECT: higher wear resistance of the cutter plate that is ensured by vibration amplitude control during cutting cycle.
