CUTTING TOOL Russian patent published in 2010 - IPC B23B29/00 B23D51/00 

FIELD: mechanical engineering.

SUBSTANCE: cutting tool contains a casing with at least one mortise wherein a cutting plate is installed and fixed and a damping element of a basically cylindrical shape installed at a gap in the casing central hole limited by a bottom on the cutting plate part and connected to the hole for delivery of a cooling-and-lubricant liquid to the cutting plate. For improved efficiency of vibration damping the tool is equipped with a bushing with an inner annular gear installed in the said casing central hole. On the butt end of the damping element turned towards the cutting plate a projection is arranged whose apex interacts with the conic indentation in the bottom of the casing central hole. The indentation cone angle exceeds that of the projection cone. In proximity to the damping element butt end turned towards the cutting plate an annular gear is arranged interacting with the bushing inner annular gear above-mentioned.

EFFECT: increased efficiency.
