Abstract
A process for retruing a profile in an abrasive wheel is provided. A lathe table including an edged cutting tool is used for fixturing a grinding wheel having an outside metal edge and an abrasive matrix adjacent thereto for rotation along an axis compatible for lathe removal of material at at least the outside edge of said wheel. A predetermined amount of material along said edge with the edged lathe cutting tool is removed using the lathe cutting tool. A rotating electrical discharge profiling tool which is attached to an electrical discharge machine is used for profiling of the wheel by electrical discharge machining of the abrasive surface with the rotating electrode. The process uses a machine specifically designed for electrical discharge machining of the profile. The machine also has a mechanism cutting a predetermined profile into the electrode without removing it from the machine.
