Patent ID: 7402005

Claim:
A cutting tip for a cutting mill for automatic milling work with the basic form of a parallelogram along whose longitudinal sides straight cutting edges ( 1 ) are formed with at least one pair of cutting tips ( 2 , 3 ) which are arranged on at least one of the parallelogram transverse sides with a convex curve attached to them wherein at least one the convex curve's radius is much greater than the radius of curvature of the radius' cutting edges ( 2 ), characterized in that between the radius cutting edge ( 2 ) and the convex curved cutting edge ( 3 ) is an edge area ( 4 ) having a concave curvature such that based upon the angle of the cutting tip, either the radius cutting edge ( 2 ) or the convex curved cutting edge ( 3 ) comes in contact with a work piece to be milled and further wherein when the convex curved cutting edge is in a cutting position, a first distance between a center (M) of the parallelogram and a first tangent line (T 1 ) tangent to the convex curved cutting edge is greater than a second distance between the center (M) and a second tangent line (T 2 ) tangent to the radius cutting tip and parallel to the first tangent line (T 1 ).
