Abstract
A dual roll grinder employs a first and second work station including a dual drive headstock disposed therebetween. A grinding assembly and the dual drive headstock translatably move along a bed to engage rolls in either of the two stations. This permits unloading and loading of a new roll in the station not currently active.
