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 +/&#x2212;1 to 40% with a period of 1 to 30 seconds.

Grinding wheel for roll grinding and method of roll grinding

Iron and steel rolls are ground to production quality requirements with a grinding wheel that requires minimal wheel wear compensation, profile error compensation or taper error compensation during the grinding process. The grinding wheel consists essentially of a superabrasive material selected from the group of natural diamond, synthetic diamond, cubic boron nitride, and mixtures thereof, in a bond system, for a grinding wheel with extended wheel life, and which removes minimum amount of stock off the roll to achieve desired roll geometry.
