Abstract
A method of processing a vehicle wheel/rim preform with a centersection/spider and an annular wall extending around a first rotational axis and having an annular surface defining axially spaced, annular inboard and outboard bead seats. The method includes the steps of: providing a workpiece support having a chuck assembly that is rotatable around a second axis and at least one rim wall support assembly; engaging the chuck assembly with the centersection/spider to maintain the vehicle wheel/rim preform in a processing position; engaging the at least one rim wall support assembly with the annular wall to exert thereon a force with a radial component to thereby stabilize the wheel/rim preform; and processing the vehicle wheel/rim preform at the annular surface fully axially between the inboard and outboard bead seats.
