1. A process for retruing a profile in an electrically conductive abrasive wheel comprising:

  • providing a lathe table including at least one edged cutting tool;

    fixturing the wheel having at least one outside metal edge and an abrasive grit matrix adjacent thereto for rotation along an axis compatible for lathe removal of metal material at at least the outside edge of the wheel;

    removing a predetermined amount of material along the outside edge with the edged cutting tool;

    providing a rotating electrical discharge profiling tool attached to an electrical discharge machine, for rotating the electrical discharge profiling tool along an axis in a direction to provide electrical discharge profiling of an abrasive surface of the abrasive grit matrix of the wheel; and

    ,profiling of the wheel by electrical discharge machining of the abrasive surface with the rotating electrical discharge profiling tool.
