Upper and lower working rolls 2a, 2b are ground while moving respective grindstone devices 3a, 3b in reverse directions, whereby the region of grinding for the upper working roll 2a and that for the lower working roll 2b are maintained in symmetry with respect to the center of rolls, one on the operating side and the other on the driving side.
The grinding face—the part of the wheel that addresses the work—is on the periphery of a straight wheel. A common variation of the straight wheel design is the recessed wheel, so called because the center of the wheel is recessed to allow it to fit on a machine spindle flange assembly. On some wheels, the cutting face is on the side of the ...
