A machine for reprofiling wheels of rail vehicles includes, for each wheel of a wheel set, a pair of support rolls arranged spaced from each other in a plane normal to the axis of the wheel set. The peripheral surface of each support roll has an axially extending carrying zone and an axially extending transfer zone following the carrying zone in a direction toward the center plane of the wheel set and being inclined with respect to a horizontal line through an angle greater than the angle included between the desired profile to be machined into a portion of the wheel opposite the transfer zone and a horizontal line. |
