With a total of 5 patents to his name, Geary has developed innovative tools that enhance the efficiency and effectiveness of grinding and cutting processes.

Latest Patents

One of Geary's latest inventions is the Brazed Diamond Dressing Tool. This dressing blade is designed for finishing and reconditioning both new and used abrasive grinding and cutting tools. It features a slab-shaped shank with an extension that protrudes longitudinally. Superabrasive grains are strategically placed on the surface of the extension and secured by a brazed metal composition. This composition is created by brazing a powdered mixture of brazing metal components and active metal components. The tool's specific extension configurations allow for the alignment of superabrasive grains in a single-layer arrangement, facilitating precise dressing and simple fabrication. The novel dressing tool is noted for its excellent wear characteristics.

Another significant patent is the Article of Superabrasive Coated with Metal. This process involves metal coating diamond superabrasive particles by heating them in the presence of coat-forming powder of a metal compound under an inert atmosphere. The metal compound contains a metal that can be thermochemically reduced by the superabrasive substance, which acts as the reducing agent. This process results in a chemical bond at the interface between the outer metal layer and the superabrasive particle substrate. The metal-coated superabrasive particles can be treated in situ with hydrogen and easily separated from excess coat-forming powder through filtration. These product particles are ideal for various applications in metal-bonded cutting, machining, dressing, and other abrasive tools, particularly diamond film inserts and single-layer diamond tools.
