Abstract
The present invention relates to a method and apparatus for reprofiling the wheels of a railroad wheelset by circumferentially milling the wheelset while the wheels are driven and partly supported by drive rollers, the wheelset being partly supported at its bearing housing. Before profile milling, a reference surface is created by a turning operation as base for measuring the radial infeed of the profile milling cutter. The turning tool required is disposed on the profile milling cutter which is lockable secure against rotation. By coordinating the position of the milling devices with the position of the respective turning devices a positional relation is automatically established between the milling device and the axis of the wheelset.
