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.

We claim: 1. A method of grinding a ferrous roll having a rotating roll surface with a rotating grinding wheel, the ferrous roll having a hardness greater than 65 SHC and a minimum diameter of at least 10 inches and a length of at least 2 feet, the method comprising:a) mounting a grinding wheel on a machine spindle and setting an angle between the grinding wheel rotational axis and roll rotational axis less than about 25 degrees;b) bringing the rotating wheel into contact with the rotating roll surface and traversing the wheel across an axial roll length of the roll, while maintaining a ratio of axial taper tolerance (TT) to radial wheel wear compensation (WWC) of greater than 10; andc) grinding the roll surface to a surface roughness Ra of less than 5 micrometer while leaving the roll surface substantially free of feed marks, chatter marks, and surface irregularities.
