Abstract
A method of grind hardening a workpiece is provided. The method may include securing the workpiece in a workpiece retainer and a grind tool in a tool retainer, rotating the grind tool in a first angular direction at a first angular speed, controlling the workpiece and tool retainers such that the grind tool engages the workpiece, and controlling the workpiece and tool retainers such that the grind tool is guided along a grinding track of the workpiece. The grind tool may engage and/or disengage the workpiece at portions of sacrificial material disposed thereon. Coolant and cleaning nozzles may be provided and controlled such that at least a portion of the coolant from the coolant nozzle is diverted to the cleaning nozzle in a manner which reduces heat dissipation, improves thermal efficiency of the grind hardening and reduces loading of the grind tool.
