Abstract
Method for producing a machining segment (51) for a machining tool from a powdered or granular first matrix material (56), first hard material particles (57), which are arranged according to a defined first particle pattern, and second hard material particles (58), which are arranged according to a defined second particle pattern, the machining segment being connected by an underside (61) to a basic body of the machining tool. The machining segment (51) has on the side surfaces a projection of the second hard material particles (58) with respect to the first matrix material (56).

A method for producing a machining segment for a machining tool from a powdered or granular first matrix material, first hard material particles arranged according to a defined first particle pattern, and second hard material particles arranged according to a defined second particle pattern, the machining segment being connected by an underside to a basic body of the machining tool, the method comprising the following steps:
- building up a green body from the first matrix material, the first hard material particles and the second hard material particles, wherein the first hard material particles are arranged in the first matrix material according to the defined first particle pattern and the second hard material particles are arranged in the first matrix material according to the defined second particle pattern;
- compacting the green body under the action of pressure between a first press punch forming a first side surface of the green body, and a second press punch forming a second side surface of the green body, to form a compact body;
- and
- further processing the compact body under the action of temperature to form the machining segment;
- wherein, when compacting the green body, a first film of a film material is arranged between the first press punch and the green body and a second film of the film material is arranged between the second press punch and the green body, wherein the film material has a hardness less than the hardness of the first matrix material.
