ABSTRACT:
The invention pertains to a nozzle for applying a liquid coolant to the grinding surfaces of a rotating grinding wheel wherein the nozzle removes the moving air film and loose particles immediately adjacent the grinding wheel surface before cooling the surface with the liquid coolant. The moving air film and loose particles adjacent the wheel grinding surfaces are removed by a flow of coolant liquid directed in a direction at least partially counter to the direction of grinding wheel surface movement, and to minimize the reoccurrence of the surface air film after removal thereof the grinding wheel surfaces are partially shielded and baffled immediately prior to application of the coolant liquid thereto for cooling purposes. Further, the application of coolant liquid for cooling purposes occurs immediately prior to engagement of the grinding surfaces with the workpiece, before a significant surface air film can occur.
