Abstract:
1. A method of making a superabrasive tool, comprising the steps of: a) providing a substrate; b) providing a template having a plurality of apertures corresponding to a predetermined pattern; c) placing the template on a transfer sheet; d) filling the apertures with a plurality of superabrasive particles; e) removing the template, such that the superabrasive particles remain in place on the transfer sheet in accordance with the predetermined pattern of the template; f) affixing the plurality of superabrasive particles in the predetermined pattern on an exposed surface of the substrate by transferring the superabrasive particles to the exposed surface of the substrate using the transfer sheet, such that the superabrasive particles become affixed to the exposed surface of the substrate in accordance with the predetermined pattern; and g) brazing the plurality of superabrasive particles directly to the exposed surface of the substrate in accordance with the predetermined pattern using a brazing alloy by applying the brazing alloy to the substrate and the superabrasive particles, the brazing alloy being provided as a sheet of amorphous braze, wherein the brazing alloy includes a material selected from the group consisting of titanium, vanadium, chromium, zirconium, molybdenum, tungsten, manganese, iron, silicon, aluminum and mixtures or alloys thereof.
