The Light Profile Grinder is a precision grinder used to complete the final stages of profile grinding on the rail head after aluminothermic or flash-butt welding. It has been specifically designed to allow very accurate adjustments, so that the whole rail head top can be perfectly restored in a single operation. Two vertical rollers, seated on the rails can be used to ensure a perfect rail profile copy in every position.

When it is not in use, a quick collapsible supported seated on one sleeper maintains the grinder steadily on the rail.
