Abstract
A grinding machine has a wheelhead movable tinder computer control perpendicular to the axis of a composite workpiece, mounted between a headstock and a tailstock, and workrests slidable along front and rear rails. Between the workrests are sandwiched rigid cover-spacers to protect the rails and prevent lateral movement of the workrests. A spring-operated thrust bar may be supported against a fixed dressing wheelhead to clamp the stack of cover-spacers and workrests together, in order to accurately locate and space apart the workrests.
