This object is solved by the features of claim 1.

In the dependent claims advantageous and expedient embodiments of the invention are mentioned.

The invention is based on a processing member for use on a separating blade for the material-removing processing, in particular of a mineral-containing material, wherein the processing member comprises cutting members, wherein the cutting members are bound with a binder in a solid state.

The separator sheet is advantageously present as a saw blade, for example as a diamond saw blade, in particular for use on a joint cutter.

In the following, the terms thickness, width and length are used for dimensions of the machining element. Advantageously, the dimensions extend so that they are formed perpendicular to each other. By a thickness of the processing member is meant a dimension of the processing member in a radial direction on the separating sheet in the arranged state, with a width of the processing member one dimension in the axial direction on the separating sheet and with a length of the processing member one dimension in the circumferential direction of the separating sheet.

The essential aspect of the invention is now to be seen in that the processing member comprises at least two sections of material, wherein at least a first portion of material is formed as a cutting section, wherein in the first section of material cutting organs bound with a binder in a first material composition as a solid, wherein a second material section a second material composition different from the first material portion.

As a result, wear of the processing member is controlled. In particular, this defines a defined wear behavior and / or cutting behavior of the machining element. Also, this makes the processing device comparatively inexpensive to produce.

The processor is particularly useful as a tool, e.g. as a diamond tool, for example as a diamond cutting body, in particular in the form of a saw blade machining member. Advantageously, the processing member is, for example, as a processing body, e.g. as a log, available. Advantageously, the processing member is designed for mounting or for mounting on a separator sheet or saw blade. For example, the machining element is present as a crevice saw blade machining element.

As cutting members are in particular abrasive, e.g. comparatively hard materials, such as diamond, corundum, silicon carbide and / or cubic boron nitride understood. The cutting members lie, in particular in comparison to the processing member, as comparatively small bodies, e.g. as particles, before.

Binders are understood to be synthetic resin, ceramic binders, metallically sintered binders and / or galvanic binders.

The cutting members are present together with the binder in particular as a solid-like bond. The processing member is preferably present as a solid.

The second material section can also be present as a cutting section. Advantageously, the second material section comprises a binder different from the first material section and / or a different concentration of cutting members. If both the first and the second material section comprise cutting elements, then the cutting elements can differ in their size, shape, density or concentration and / or in the material between the material sections.

A section of material may contain fillers and additives. For example, a material section may comprise supporting grains. The support grains serve, for example, to increase the strength of the material section. In particular, the backing grains have no abrasive or abrasive, e.g. cutting properties, they thus do not contribute to the material-removing properties of the processing organ.

It proves to be advantageous that the processing member has three, in particular five material sections. As a result, different cutting properties of the material sections can be realized.

Moreover, it is advantageous that the second material section does not comprise cutting elements.

Moreover, it is advantageous that the different material sections are formed adjacent to one another, in particular along a width of the processing member, on the processing member.

Advantageously, the material sections are next to each other, successively present on the processing element. It is conceivable, for example, that the material sections in the arranged state of the processing member on the separating blade in the axial direction of the separating blade seen in succession, in particular alternately, are present. It is also conceivable that the various sections of material along a particular circumferential length of the processing member adjacent to each other, e.g. next to each other and / or consecutively, on the processing member, in particular in a circumferential direction, e.g. circular, consecutive on the separator sheet, are present.

It is further proposed that the processing member has in particular exactly two mutually different material sections, wherein the material sections are formed adjacent to each other on the processing member. As a result, the processing element is present as a comparatively stable solid. Preferably, the different material sections are alternately adjacent to each other.

In an advantageous embodiment of the processing element, a material section extends over a complete length and / or a complete thickness of the processing member.

In particular, a material section extends in the arranged state of the processing member on the separating sheet along a full circumference, for example, a full circumferential length. It is also conceivable that the material section extends in the radial direction over a complete thickness of the processing member.

It is also advantageous that the material composition of the first and of the second material section is designed such that during machining the second material section wears out more strongly than the first material section.

By way of example, the first material section is designed to lift a material to be processed in the arranged state on the separating blade during processing, the second material section being designed in the assembled state on the separating blade during processing by the material to be processed, in particular in comparison to the first material section to be worn and / or worn.

Advantageously, the round and / or curved surface forms an outer side of the cuboid in the arranged state on the separating sheet, for example a circumferential outer side, in particular the outer side is present as a material-removing surface. For example, a surface of the processing member has a rounding, e.g. a radius which corresponds to an outer radius, e.g. corresponds to a cutting or machining radius of the release sheet, in particular the master sheet, with processing organ.

The processor has e.g. a spherical surface. For example, the processing member comprises a radius on or on a surface along its length and / or along its width. In particular, the processing member has a radius in the arranged state on the release blade in the axial and / or in the circumferential direction on or on a surface.

It proves to be advantageous that the processing member is fully present on the release sheet. It is conceivable that the processing element is annular or hoop-like. It is conceivable that the processing member completely encloses the circumference of the release sheet.

It is also advantageous that the processing member is arranged on the circumference of the release sheet, in particular on the circumference of a master sheet of the release sheet, and the first material portion of the processing member at least one axial width of the release sheet, in particular an axial width of the stem sheet, covered.
