Method of making a tool component
First Claim
1. A method of producing a tool component comprising a working portion of bonded abrasive particles, which includes a non-homogeneous region, the method including the steps of providing at least two sources of a material comprising abrasive particles in a suitable binder, the materials of the sources differing from each other, delivering a quantity of the materials to a zone where mixing occurs and applying the mixed materials to a surface to produce a layer of the mixed materials on the surface.

Abstract
A method of producing a tool component comprising a working portion of bonded abrasive particles including a non-homogeneous region. The method includes the step of providing at least two sources of a material comprising abrasive particles in a suitable binder, the materials of the sources differing from each other. The material of one source may comprise diamond or cubic boron nitride particles, whilst the material of the other source may comprise carbide particles. Alternatively, the materials of the two sources may contain the same abrasive particle, such as diamond or cubic boron nitride particles, but in different particle sizes. The materials are delivered to a zone where mixing occurs, and the mixture is applied to a surface to produce a layer of the mixed materials on the surface, typically by spraying. By controlling the quantity of material from each source which is delivered to the mixing zone, different mixtures of the two abrasives can be created. In this way, layers, e.g. one on top of the other, can be produced which differ from their neighbours in abrasive particle composition. These layers, on sintering, form non-homogeneous regions in the working portion of a tool component.
