Patent ID: 8491358

Claim:
A method for orienting superabrasive particles in a tool, comprising: providing a plurality of superabrasive particles having a preselected average size; preselecting a thickness for an amorphous braze layer to be applied to a substrate, wherein the thickness is based on the average size of the plurality of superabrasive particles; applying an amorphous braze layer to the substrate at the preselected thickness; dispersing the plurality of superabrasive particles onto the amorphous braze layer; melting the amorphous braze layer to cause the plurality of superabrasive particles to rotate and sink into the amorphous braze layer, wherein the thickness of the amorphous braze layer is such that the rotation and sinking of the plurality of superabrasive particles is halted by the substrate in an attitude whereby substantially all working ends of the plurality of superabrasive particles are sharp portions; and cooling the amorphous braze layer.
