摘要
An abrasive material grinding wheel for grinding the plate front face of an as-cast railroad wheel to remove sprues and riser pads has a projecting and leading edge to extend the ground surface into close proximity to a hub and fillet section of the railroad wheel, which grinding wheel has a reduced wall thickness, a recess for receiving a retaining flange to reduce the elements extending from the outer face of the grinding wheel, and a sloped outer grinding surface projecting the leading edge and providing a grinding-wheel surface adequate to grind the entire riser pad from the plate front surface between the wheel rim and the front hub fillet, and to generally retain the grinding wheel outer surface contour during multiple grinding operations.
