| 摘要 |
The invention relates to a cutting insert, intended for chip removing machining, which includes a cutting geometry surface (7) which in a direction from a cutting edge (11) towards the middle of the insert, includes a primary chamfer (24,27,28) that transforms into a chip removing surface (25), which is inclined in the direction inwards/downwards in order to permit sinking of a chip being under formation, and which transforms into a deflection surface (26) arranged to be met by the chip and at least initiate deflection or guiding away of the same from the cutting insert. The angle of inclination ( delta ) of the chip removing surface (25) does not exceed 18 DEG , in addition to which, the level difference N1 between the primary chamfer and the chip deflection surface (26) amounts to a maximum of 0,20 mm. <IMAGE> |
