<p>In an underfloor wheel set lathe for reprofiling the wheel tyre contours (16, 17) of railway wheel sets (5), having four driven friction rollers (18, 19, 20, 21) two rotational supports (30, 31) and a machine control (52) it being possible to press the friction rollers in pairs against one wheel tyre contour (16, 17) each of a wheel set (5), a slipping of the friction rollers on the wheel tyre contours is avoided in that a device (54, 55, 56, 57) for determining the slip occuring between a friction roller and a wheel tyre contour is provided which controls the advancing speed of the rotational supports (30, 31) as a function of the determined slip. <IMAGE></p> |
