Technical features
Independent units consisting of a 2/3 jaw chuck with a built in pneumatic cylinder Reduced dimensions on the machine, high gripping force and very high precision Case hardened body to assure highest precision and long chuck life Important! Due to the friction between fixed manifold and rotating central body, the indexing table must provide a higher rotation torque than the one shown in the schedule below
