Abstract
A method and a machine for performing final finishing operations upon a wheel to minimize both axial and radial run-out. The assembled wheel, including the rim and attached wheel center is placed in the machine and the rim and particularly the bead seat portion is deformed both radially and axially into a true condition. While held in this condition, the center hole, the bolt hole chamfers, and the axial locating surfaces are finish machined.
