CUTTING TOOL Russian patent published in 2010 - IPC B23B27/16 B23C5/20 

FIELD: technological processes.

SUBSTANCE: cutting tool comprises body, cutting and support plates, having axis of symmetry, and facility for fixation of cutting plate on body. At the same time cutting plate has front surface, opposite support surface and side support surfaces, and is installed and fixed on support plate in seat limited by lower support wall arranged in body, and side support walls arranged on support element located over lower support wall and connected to body, and interacting with side surfaces of cutting plate. Support surface has lower support surface, which interacts with lower support wall of seat, upper support surface interacting with lower support surface of cutting plate and side surfaces arranged between them. In order to increase resistance by reduction of vibrations in process of cutting, upper support surface of support plate is arranged as conical with axis arranged perpendicularly to lower support surface of support plate and displaced from its centre of symmetry, when installed in seat, axis of specified conical surface is installed between centre of cutting plate symmetry and top of angle produced by side support walls of support element. Besides support element is arranged with the possibility of elastic swinging in plane, which is perpendicular to bisector of specified angle between side support walls.

EFFECT: improved resistance.
