Milling insert for chip removing machining

A face milling cutter for chip removing machining, the milling cutter comprising a milling cutter body (10;

• 110), the milling cutter body (10;
• 110) comprising a number of insert seats (11;
• 111), the insert seats (11;
• 111) having grooves/notches that extend parallel with the rotational axis (C2-C2) of the milling cutter, the milling cutter comprising a number of milling inserts (1;
• 101) that are mounted in the insert seats (11;
• 111), the milling cutter comprising wedges (12;
• 112) adjacent to the insert seats (11;
• 111) for the adjustment of the milling inserts (1;
• 101) in the axial direction of the milling cutter, each one of the milling inserts (1;
• 101) comprising at least three main cutting edges (H1-H3;
• H101-H104) and three associated minor cutting edges (B1-B3;
• B101-B104), characterized in that each one of the milling inserts (1;
• 101) on the underside (L1;
• L101) thereof is provided with at least two, mutually intersecting, sets of rectilinear grooves/notches, said sets of grooves/notches defining essentially pyramidal projecting parts (P1;
• P101), that said sets of grooves/notches intersect opposite side surfaces (S1-S6;
• S101-S108) of the milling insert (1;
• 101), and that when the milling insert is seen a planar view the rectilinear direction (R1-R3;
• R101-R102) defined by each set of grooves/notches forms a right angle with a tangent of a minor cutting edge (B1-B3;
• B101-B104).
