Post-grinding rail roughness level has a big impact on the performance of the rails. For cases where roughness values were particularly low, flange-climbing derailments occurred [9][10], when a wheel of a rail vehicle climbs up a rail. The names used for relevant parts of wheels and rails and a typical sequence of events leading to a flange

Above: Grinding wheels with different grain sizes. The grain size in your grinding wheel is classified as coarse 8-30, medium 30-60, fine 70-180 and very fine 200-600.The material removal rate will be more for your grinding wheel with coarse abrasives and less for a wheel with fine abrasives; also grinding wheels with fine or very fine abrasives gives a better finish …
