| 摘要 |
The invention relates to a machining tool having a determined or non-determined cut and to a method for the production thereof. The tool is provided with a hard metal substrate (10). A diamond or DLC layer (12) is applied to the substrate (10). Several edges (16) are formed by abrupt alteration of layer thickness in the surface of the diamond or DLC layer (12). The diamond or DLC layer is applied using a CVD method. The diamond layer is applied using a CVD method and the DLC layer is applied using a PVD or CVD method. A mask (14) is applied to the layer. The edges (16) are produced by etching points on the surface that are not covered by the mask. As a result, it is possible to significantly increase the functionality of the tool. The edges (16) can be used as additional cutting edges or free areas can be transformed for discharging coolants or lubricants and removed material. |
