Schunk presents the wedge hook power chuck Rota NCE, featuring high rigidity, maximum payload capacity and a lightweight design. Compared to traditional power chucks, the Rota NCE reduces by up to 30% the mass moment of inertia, therefore ideal for high process dynamics and productivity with minimal energy consumption. The reduced weight allows indeed significantly faster acceleration and deceleration of the chuck, achieving superior energy efficiency and significant saving by minimizing cycle times especially in large-scale production.

Developed by the technicians of the Schunk competence center for lathe chuck technology and stationary clamping systems in Mengen, the power chuck has a lightweight and optimized design, enabled by a crown structure beneath the jaw guide, circular recesses between the guideways and a conical contour, not effecting the rigidity. The forces are diverted directly into the spindle holder. The device has been especially designed for CNC lathes with short-stroke cylinders, and is fully compatible with conventional lathes of Asian manufacturers, and will be available starting spring 2017 in four sizes, with diameters of 170 mm, 210 mm, 254 mm and 310 mm, as well as clamping forces of 65 kN, 100 kN, 125 kN and 150 kN. The chuck received the iF Design Award 2016 for its functionality, efficiency and design.
