Short description: Wedge bar chuck with quick-change jaw system. The accuracy of the jaws is maintained as long as they are used only on the same chuck and the base and top jaws are stored screwed together for recurring tasks.

Technical features: With jaw locking, chuck body completely surface-hardened, visual marking for quick jaw adjustment, outer shape including splash guard edge, lubrication options for heavily stressed sliding surfaces, including safety key, high corrosion protection.

Applications: Optimized for turning applications that require extremely high clamping forces, maximum roundness accuracy, and reliable long-term repeat accuracy. In conjunction with a base plate for stationary use on milling machines, dividing heads, and machining centers.

Advantages: Maximum clamping force due to the wedge bar system, roundness and flatness tolerance twice as accurate as required in DIN accuracy class 1, very high jaw change repeat accuracy, balanced and jaws ground for roundness in the chuck.

Further information: Wedge bar chuck DURO-T, size 315, 3-jaw, cylindrical centering mount, with base jaws.
