Abstract
An electrically operated grinding wheel is described wherein the grinding wheel is adapted with a slidable tool rest member which will automatically position itself at a preselected distance from the grinding wheel. As the grinding wheel becomes worn and its wheel diameter decreased, the slidable tool rest member will be automatically moved towards the grinding wheel and a safe operational spacing between the grinding wheel and the tool rest member maintained. This is achieved through a motorized gear train which is actuated by a photoelectric cell carried within the housing of the tool rest member. Another feature is that as the wheel is worn and approaches a preselected minimum diameter, a switch is automatically actuated which will turn off the power to the grinding wheel preventing its operation until such time that the worn grinding wheel is replaced.
