WS 3.3800 Double Workholding System DUO clamping against the central fixed jaw, mechanically operated jaw width 80 mm Advantages ● Compact design ● Highest position and repetitive accuracy ● with 3rd-hand function ● Extensive range of jaws ● Easy to maintain Technical data Clamping principle: Operation: clamping against the central fixed jaw mechanically with a torque wrench DUO 80 / 200 Length of the base: Jaw width: Clamping force*: Max. jaw opening: DUO 80 / 240 Length of the base: Jaw width: Clamping force*: Max. jaw opening: Application Double workholding systems DUO are particularly suitable for double clamping - both in horizontal and vertical plane. Accessories • Clamping jaws and jaw inserts, accessories for mounting, positioning and operation see data sheet WS 3.380Z Application example Description Double clamping systems DUO convince by their short overall length, durability and precision. The guidance and sealing principle works without any delicate sheet metal covers or plastic wipers. The centrally arranged fixed jaw as a central jaw is without load and thus absolutely zero point stable. The workpieces are positioned close to each other, and thus reducing the travel paths of the machining centre to a minimum. The purely mechanical operation enables clamping also with low and always reproducible clamping forces. These characteristics turn the double workholding systems DUO into a flexible standard fixture for a wide variety of applications in modern production. For double workholding systems DUO, a wide range of clamping jaws is available (see data sheet WS 3.380Z). Mechanical double workholding system with spindle drive Versions Mechanically operated The two movable jaws are guided to the central fixed jaw via a right-left threaded spindle. An integrated pre-clamping system (3rd hand function) holds the workpiece inserted first in its position, while the second workpiece is positioned. With this function, the clamping –1 stroke varies between 12      4 mm (DUO 80 / 200) and 48  –  50 mm (DUO 80 / 240). The joint and uniform clamping force build-up can then take place. Customised versions Double workholding systems DUO can also be delivered as customised versions. For example *Important note with individual fixing holes or special jaws.
