Abstract

A below-floor lathe for reprofiling the rims of railroad-vehicle wheel sets, with four driven friction rollers, two rotating supports, and controls. The friction rollers can be forced in pairs against the outer surface of each rim in a wheel set. A detector determines the level of slippage that occurs between a friction roller and a rim surface and varies the rate at which the rotating supports advance in accordance with the level of slippage detected.
