High Speed Grinding is based on the concept of circumferential grinding. All grinding stones are passively propelled and hydraulically pressed onto the rail. The patented technology allows working speeds of up to 100 km/h. The material removal of 0.1 mm is normally achieved by three grinding passes (two rough passes and one smoothing pass).

HIGH SPEED GRINDING PREVENTATIVE RAIL CARE

 · Fichier PDF

High Speed Grinding features a series of free rotating, non-powered grinding stones, which are offset by a certain angle relative to the rail. When dragged along the rail this offset angle produces an autorotation and a relative motion which grinds the rail. The rail is not reprofiled but is artificially worn. Because of the respective contours of rail and grinding stone, the contact line ...
