Abstract:
A method of surface grinding a planar flange surface of a flange of a wheel hub, said method comprising the steps of:(a) fitting a wheel hub having a flange with a surface to be ground and a sleeve portion with a wheel bearing having inner race fitted onto the sleeve portion and an outer bearing race formed with a mounting surface for attachment to a motor vehicle;(b) clamping said mounting surface of said outer bearing race to an annular stationary workpiece carrier which surrounds a driven spindle of a machine tool by a plurality of clamps, thereby mounting said wheel hub on said workpiece carrier;(c) flexibly connecting said spindle to said hub; and(d) rotating said wheel hub and said flange about a hub axis with said spindle and contacting said surface of said flange with a rotating grinding disk, thereby surface grinding said flange.
