FIELD: metal working.
SUBSTANCE: group of inventions relates to the field of metal working and can be used in restoring the profile of the wheelset of a railway vehicle. The method includes positioning the wheelset on one or more rollers, determining the centre of rotation of the wheel on the wheelset, determining the required constant distance between the cutting tool and the centre of rotation of the wheel, and rotating the wheel. The profile of the wheel is therein milled using the cutting tool, the centre of rotation of the wheel is moved relative to one or more rollers while retaining said one or more rollers in a secured position on the machine, the movement of the centre of rotation of the wheel is tracked, and the cutting tool is moved, ensuring the location thereof at the required constant distance between the cutting tool and the centre of rotation of the wheel. The group of inventions also includes variants of the method and variants of apparatuses implementing said methods.
EFFECT: use of the inventions allows for a simplification in the process of restoring the profile of wheels.
