International ClassB24B 001/00Foreign Application Priority Data1994-10-20 DEAbstractIn the proposed process of machining the top surface of a rail by a circumferential grinding by means of at least one abrasive product, which is moved along the rail and urged against the top surface of the rail and rotates about an axis of rotation which includes an acute angle with the longitudinal direction of the rail, desirable grinding conditions are ensured in that a freely rotatable abrasive is caused to roll and slide on the top surface is caused to roll and slide on the top surface of the rail in frictional contact therewith and thus to grind said top surface.Other References
