Average grinding performance depends on the type and size of rail defects to be eliminated, the quality of grinding wheels and on the hardness of the rails. As a reference value for clean running surface grinding, in case of max. 0.2 mm corrugation wear depth and normal R220 (MSZ EN 13674) quality rails it is possible to achieve 0.2 mm grinding depth in one run and appr. 250 track meter/hour.
