An on-car brake lathe is provided with a runout compensation system configured to monitor the rotational position of a pair of slant discs within an aligning joint of the on-car brake lathe. The system monitors the amount of runout present between the rotating components of the on-car brake lathe and the wheel hub to which the on-car brake lathe is secured. The system calculates the appropriate rotational position for each slant disc within the aligning joint required to impart a necessary adjustment in the wheel coupling rotational axis in order to align the on-car brake lathe with the rotational axis of the wheel hub. Finally, an adjustment mechanism is activated to rotationally drive each slant disc directly to the calculated rotational position with a minimum amount of rotational movement based on the current rotational position of each slant disc and the required calculated rotational positions.

The system monitors the amount of runout present between the rotating components of the on-car brake lathe and the wheel hub to which the on-car brake lathe is secured, and calculates a relative rotational position for each slant disc within the aligning joint required to impart a necessary adjustment in the wheel coupling rotational axis to align the on-car brake lathe with the rotational axis of the wheel hub. An adjustment mechanism within the aligning joint is configured to rotationally drive each slant disc to the calculated relative rotational positions with a minimum amount of rotational movement based on the current relative rotational position of each slant disc and the required calculated relative rotational positions.

A method for machining a wheel hub assembly for a vehicle includes providing a radially outer ring having a first radial flange, a radially inner hub having a second radial flange facing the first flange, and a plurality of rolling elements disposed between and rotatably coupling the outer ring and the hub. The hub is rotated simultaneously and asynchronously about the outer ring while machining a front surface of the second flange, which faces away from the first flange, and while rotating the outer ring about an axis of rotation of the wheel hub assembly, so as to form a machined surface of the second flange. The machined surface of the second flange is perpendicular to the axis of rotation and parallel to a front face of the first flange opposite to the front face of the second flange.
