Patent ID: 7121768

Claim:
A cutting head for being secured to an adapter, in a machine tool for chip removing machining, wherein the cutting head comprises a flange with a first side creating a coupling surface adapted for being secured to the adapter, and an on the opposite side of the flange situated, other side creating at least one surface with an outwardly extending protrusion, with securing means adapted for the securing of a cutting insert with at least one cutting edge, wherein the at least one surface defines a plane creating an inclined angle in relation to a plane parallel to the coupling surface, whereby the cross-sectional thickness of the flange increases from a first lateral side to an oppositely situated other lateral side; wherein a concave surface with a radius between the at least one surface of the flange and the protrusion creates a smooth transition between the flange and the protrusion and the protrusion extends from that part of the flange having the increased thickness; and wherein the protrusion and the flange with the at least one surface with an inclined angle in relation to the plane parallel with the coupling surface, is one integrated piece whereby the weight of the cutting head is reduced as compared to the strength of the cutting head, and the natural frequency of the cutting head is increased when this is secured to the adapter.
