ABSTRACT:
An apparatus for grinding molded friction products comprises a rotary indexing table with a substantially horizontal indexing table. The table surface indexes from one indexing position to another. Tool fixtures support friction product parts to be ground on a friction surface thereof. The tool fixtures are disposed on the rotary indexing table at the indexing positions. A grind stone is disposed above the indexing table surface for grinding the friction product part supported in the tool fixture at one of the indexing positions. The grind stone rotates about a grind axis which is substantially parallel to said central axis of said indexing grind table, but can be tilted by a small angle so as to provide a skim cut grind to the product. The method provides for performing operations at all indexing positions simultaneously.
