Abstract (en)
[origin: CA2771550A1] The invention relates to a ready-for-use ceramic cutting insert for machining work pieces, produced by sintering a blank and comprising an upper and a lower face, both of which have a support surface for mounting in a clamp mounting of a cutting tool, lateral faces connecting the upper and lower faces, and cutting edges which have chamfers. In order to at least partly avoid re-machining after sintering, the support surfaces of the upper and lower faces and/or the chamfers have at least subareas which consist of the sinter skin produced as a result of the sintering and which have not been damaged by any material-removing treatment.
