Copier Drum Grinding

In an electrophotographic copier, it is necessary that the metal drum, which is to carry the photoconductor, be manufactured with minimum eccentricity.

In practice, drum 10 is mounted to rotate on axis 11, and its outer surface is ground by grinding belt 12, as this belt passes over fixed-position roller 13. Roller 13 tends to wear with use, necessitating redressing this roll in order to maintain accurate grinding of drum 10.

To redress roll 13, a plurality of grinding wheels (not shown) are mounted on an arbor, with their outer surfaces forming a circular cylinder having no eccentricity. This arbor is then mounted to rotate on axis 11 and, with belt 12 removed, the grinding wheels are used to dress the outer surface of roll 13, restoring its concentricity.
