Abstract:
A method for producing a machining segment for a machining tool, where the machining segment is connectable to a basic body of the machining tool by an underside of the machining segment, includes producing a green body by placing first hard material particles in a first matrix material in a defined particle pattern. The green body is compacted by pressure between a first press punch, which forms the underside, and a second press punch, which forms an upper side of the machining segment, to form a compact body. The compact body is processed by temperature or by infiltration to produce the machining segment. The second press punch has depressions in a pressing surface where an arrangement of the depressions corresponds to the defined particle pattern of the first hard material particles.
