A method for machining the wheel running surfaces of wheels for rail vehicles using a wheel machining machine is described herein. The method includes performing a rolling process on the wheels with a rolling tool that applies a rolling force to the wheels, and adjusting the rolling force by controlling the torques of drive motors of feed axles of the rolling tool.

The present invention provides a surface following nozzle, an observation device for a moving object surface, and an observation method for the moving object surface that can remove water in the vicinity of the nozzle while following changes in the shape and changes in the distance of a moving object. A surface following nozzle includes a nozzle that injects gas from a tip end thereof, a separating part that closes a base end of the nozzle, and an extending and contracting part that is provided at a rear side of the nozzle via the separating part, and extends and contracts along an axial direction of the nozzle. The extending and contracting part includes an elastic body that applies a forward force with respect to the nozzle.

The present invention relates to an electrode rolling roll cleaning apparatus for removing pollutants on an electrode rolling roll, the apparatus comprising: a cleaning part for cleaning a rolling roll by bringing the rolling roll into contact with a cleaning member; an air spraying part for spraying air onto the rolling roll; a heating part for applying heat to the rolling roll so as to dry the rolling roll; and a scraper part for mechanically removing a cleaning liquid and foreign substances attached to the rolling roll.
