Abstract:
A method of machining a brake disk assembly having a brake disk, a wheel hub, and a wheel bearing the method comprising the steps of:fitting to the wheel hub centered on a hub axis and having a sleeve, a flange protecting radially from the sleeve, and the wheel bearing having an inner bearing race fitted to the sleeve and an outer bearing race formed with an axially directed mounting surface for attachment to a motor vehicle;clamping the mounting surface of the outer bearing race axially to an annular stationary workpiece carrier and thereby mounting the wheel hub on the workpiece carrier;securing to the flange the brake disk having a pair of opposite faces extending substantially perpendicular to the axis by pressing a retaining disk against the brake disk with a force generally equal to the force with which the brake disk is pressed against the hub when the hub is mounted in a motor vehicle and bolting the retaining disk through the brake disk to the hub;rotating the wheel hub and the brake disk about the axis; andengaging the faces of the rotating brake disk with machining tools and thereby surface machining the faces.
