Method for producing a machining segment for the dry machining of concrete materials

A method for producing a machining segment for a machining tool, wherein the machining segment is connectable to a basic body of the machining tool by an underside of the machining segment, comprising the steps of:

• producing a green body by placing first hard material particles in a matrix material in a defined particle pattern, wherein the first hard material particles are placed in the matrix material with a respective projection with respect to the matrix material;
• compacting the green body 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, wherein the upper side is opposite from the underside, wherein the second press punch has depressions in a pressing surface, wherein an arrangement of the depressions corresponds to the defined particle pattern of the first hard material particles, and wherein a respective projection of the first hard material particles is received within a respective depression in the pressing surface of the second press punch during the compacting;
• and
• processing the compact body by temperature or by infiltration to produce the machining segment;
• and further comprising the step of encasing the first hard material particles with a casing material that comprises the matrix material such that there is no direct contact between the first hard material particles and the second press punch.
