| 摘要 |
The invention relates to a ready-to-use ceramic blanking die (1), which is produced by sintering a blank, as an indexable insert, comprising an upper face and a lower face (2, 3) which each have a support surface (4) for installation in a tool holder of a cutting tool, lateral surfaces (5) that connect the upper and lower faces (2, 3), and cutting edges (6) for machining workpieces. In order to least partly avoid a finishing machining step after sintering at, utilize the advantages of the finish-pressed/final-sintered contact surfaces between the blanking die and the tool and assure optimal contact of the blanking die to prevent vibrations and the attendant micro-chipping/wear, a peripheral face (7) is arranged adjacent to the cutting edges (6) and the face (7) circumscribes the support surface (4), wherein the lateral surfaces (5), the cutting edges (6) and the faces (7) consist of the sinter skin created during sintering and have not been damaged by a material-removing machining process, and only the support surface (4) underwent a material-removing machine process and does not consist of the sinter skin created during sintering. |
