ABSTRACT:
A brake lining grinder has feed wheels and an abrasion wheel defining a finishing throat through which one of a plurality of brake lining blanks are feed for simultaneously finishing the arcuate inner surface of the lining to precisely conform to the shape of the arcuate outer surface of a brake drum. The grinder includes an inlet guide surface for stacking a plurality of lining blanks for continuous automatic sequential feed through the finishing throat and the grinder further includes an outlet guide surface for receiving finished blanks for automatic gravity release from the grinder. A method is disclosed for automatically and sequentially finishing a plurality of brake lining blanks having unfinished side surfaces and an unfinished arcuate inner surface by stacking a plurality of the lining blanks on an inlet guide surface for passage across a grinding wheel and simultaneously finishing of the side and inner arcuate surfaces of the blank by the grinding wheel to a finished form conforming to the shape of the exterior outer surface of a brake drum.
