ABSTRACT:
A method of grinding a ferrous roll may include: rotating a grinding wheel on a machine spindle to form a rotating grinding wheel; rotating a ferrous roll to form a rotating roll surface; bringing the rotating grinding wheel into contact with the rotating roll surface; traversing the rotating grinding wheel across an axial roll length of the rotating roll surface; and grinding the roll surface while varying at least one or both of a grinding wheel rotational speed and a said mill roll rotational speed at an amplitude of +/−1 to 40% with a period of 1 to 30 seconds.
