9 ß Clamping tools. Power Chucks DURO-NCES for straight-toothed jaws Quick-action jaw change system with single unlocking system Securing of the position of the base jaws The special design (key bars are positioned tangentially) has a positive effect on the manner in which the chuck reacts to centrifugal forces. This means: higher rotational speed and gripping power losses are reduced (with large through-hole). The single unlocking system simplifies the handling of large special top jaws, which have to used in dependence of the work piece. Further power chucks for higher rotational speed KFD-HS Power chucks with two, three and four jaws, with large through-hole, high remaining clamping force without centrifugal force balancers. DURO-NC Power chuck with quick-action jaw change system, central jaw unlocking, large throughhole, universal draw-bar connection. KFD-HE Power chuck with large through-hole, high radial and axial true-running capacity. KFD-N Holding down power chuck for outside clamping, high clamping accuracy.
