Abstract
The present invention relates to a method for reprofiling wheel disks (7) or brake disks of a railway wheel or wheelset (6), rotatably mounted in bearing housings (9), by machining using a machine tool (12), which is designed to be portable, a wheel disk (7) of the railway wheel or the wheelset (6) being pressed against backup rolls (16) on its circumference by a clamping element (14, 15), which engages on at least one bearing housing (9), at least one of the backup rolls setting the railway wheel or the wheelset (6) into rotation, while simultaneously a tool (20) machines one of the wheel (7) or brake disks. The invention also relates to a machine tool (12) for carrying out the method. This machine tool (12) has a portable support frame (11) having a clamping element (14, 15) for engaging on a closed inner and/or outer bearing housing (9) of the railway wheel or wheelset (6), and at least one backup roll (16), which may be pressed against the outer circumference of the wheel disk (7), on whose bearing housing(s) (9) the clamping element (14, 15) engages, at a mutual distance to one another opposite to the clamping element (14, 15), a drive for at least one of the backup rolls (16), and a tool (20) for machining wheel (7) or brake disks (23) of the railway wheel or wheelset (6).
