Abstract:
1. A method for grinding the running surface ( 4 ) of a railway rail ( 1 ), by producing a relative motion between a grinding wheel ( 12 ) and the rail in the longitudinal direction thereof, the grinding wheel having a profile that mates with the profile of the running surface, and being driven by means of a motor ( 9 ), with the axis of the grinding wheel and a plane perpendicular to the longitudinal direction of the rail including an angle α deviating from 0°, the grinding wheel ( 12 ) being moved against the rail ( 1 ) up to the point of engagement, characterized in that, upon peripheral milling of the running surface, said movement of the grinding wheel ( 12 ) against the rail ( 1 ) is restricted by means of a guide ( 17 ) which can be pressed against the milled running surface ( 4 ) of the rail ( 1 ), independently of a system for regulating the depth of grinding, whereby, depending on the wear of the grinding wheel, the grinding ( 12 ) is automatically readjusted in the direction toward the rail ( 1 ) by regulating the depth of grinding.
