-/- FINISH-PRESSED/FINAL-SINTERED BLANKING DIE AND METHOD FOR PRODUCING SAME

摘要

The present invention relates to a ready-to-use ceramic blanking die (1) produced by sintering a blank as an indexable insert, the die comprising an upper surface (2) having a support surface (4) for mounting in a tool holder of the cutting tool, And side surfaces 5 connecting the lower surface 3, the upper surface 2 and the lower surface 3, and cutting edges 6 for machining the workpieces. At least partially avoiding the finished machining step after sintering and to take advantage of the finishing-press / final-sintered contact surfaces between the blanking die and the tool and to prevent vibrations and incidental micro-chipping / The peripheral surface 7 is arranged adjacent to the cutting edges 6 and the peripheral surface 7 abuts the support surface 4 and the side surfaces 5, the cutting edge 6 ) And the peripheral surfaces 7 consist of the sintered skins produced during the sintering and are not damaged by the material-removing machining process and only the support surface 4 undergoes a material- Sintered skins.
