The Evolution and Application of Rail Profile Grinding

Rail profile grinding is the term that refers to the method of controlling and maintaining the shape of the railhead, it's "profile", through grinding of the head of the rail. This represents an evolutionary step beyond the traditional defect elimination grinding where the shape of the rail, either before or after grinding, was not a factor in ...
