Abstract
A roll grinding system includes a roll with a pair of longitudinally opposite ends, a longitudinal axis extending between the ends, and an outer surface. A material removal tool is movable in a travel path along a length of the roll. The material removal tool has a generally flat working surface oriented generally parallel to the travel path. A longitudinal displacement drive is connected with the material removal tool for moving the material removal tool along the travel path. A pair of supports are respectively positioned at and rotatably carry a corresponding end of the roll. At least one transverse displacement drive is provided, with each transverse displacement drive being connected with a corresponding support and configured to move the corresponding support in directions generally toward and away from the longitudinal axis. A controller is coupled with and controls operation of each transverse displacement drive, dependent upon a position of the material removal tool along the travel path whereby the outer surface of the roll is positioned substantially tangent to the working surface of the material removal tool.
