Abstract: Apparatus for milling the end edge surfaces of truck rims to remove weld projections including a frame having a clamping means for holding the rim in an operating station, a pair of spaced apart power heads carrying cutting tools and actuator means for moving the power heads and cutting tools at a predetermined spaced apart distance transversely with respect to the axis of the rim to remove the weld projections. The upper power head and cutting tool are mounted for vertical movement and stop means carried by the upper power head directly locates the spaced apart position for the upper cutter to remove the top weld projection on the rim.
