The roller grinder is composed of bed, head frame, tail frame, bracket, Longitudinal and transverse dragging board,grinding head, measuring frame and electrical numerical control system. The workpiece is supported by the head frame, tail frame and bracket, and is driven to rotate by the head frame.
        According to the mathematical model of roll surface Generatrix, the CNC system controls the multi-axis compoundmovement of the machine tool, and the grinding wheel grinds the roll surface metal during the movement.
The on-line measuring system feeds the measuring data back to the control system of the grinding machine in real

time, and the control system controls the machine in a closed loop so as to finish the precision machining of the workpiece. Roll production, roll shaft, roll manufacturers
