| 摘要 |
The present invention relates to a milling cutter for chip removing machining, said milling cutter comprising a milling cutter body (1) with a number of cutting insert seats in connection to a chip removing end of the milling cutter body (1), said milling cutter body (1) being formed to cooperate with a tool attachment at its opposite end in the axial direction (C-C), wherein indexable cutting inserts (3) are secured in the cutting insert seats, each said indexable cutting insert (3) having a top surface (7) and a bottom surface (9) substantially parallel with the top surface (7), wherein side surfaces (10A, 10B, 10C, 10D) extend between the top surface (7) and the bottom surface (9), said indexable cutting insert (3) having the basic shape of a truncated pyramid. The invention also relates to a milling cutter body (1) and an indexable cutting insert (3), per se. Distinguishing for the milling cutter according to the present invention is that each indexable cutting insert (3) has its top surface (7) facing against the chip removing end of the milling cutter, and that main cutting edges (11 A, 11 B, 11 C, 11 D) of the indexable cutting insert (3) extend from the top surface (7) of the indexable cutting insert (3) in direction towards the bottom surface (9) of the indexable cutting insert. |
