Abstract: Embodiments of the invention can provide cryogenic treatment processes for diamond abrasive tools. One process in accordance with an embodiment of this invention can include introducing an abrasive tool into a cycling chamber, wherein the tool has a temperature of about ambient temperature; and introducing at least one cryogenic material into the chamber, wherein the internal temperature of the chamber or tool can be controlled by adjusting the flow rate of the at least one cryogenic material. The process can result in a strengthened and toughened abrasive tool. The process can be repeated multiple times.

Abstract: Embodiments of the invention can provide systems and methods for treating grinding wheels and bonded abrasive tools. A process in accordance with an embodiment of this invention is a cryogenic thermal cycling process for grinding wheels and bonded abrasive tools. Grinding wheels and bonded abrasive tools treated by cryogenic thermal cycling processes in accordance with embodiments of this invention can exhibit improved performance and service life during comparison testing against untreated tools.
