The new new UltraJet™ 3.0 power chuck is an innovative combination of the JetSleeve™ 2.0, which has been established on the market for years, and Dieboldꞌs UltraGrip™ 3.0 power chuck. The new UltraJet™ 3.0 power chucks supply coolant to the nose of the chucks, nozzles create high pressure and the coolant, air or air-oil mist will blow the chips out of the cutter area. It is almost impossible to overrun the chips in heavy-duty machining, resulting in even higher cutting values and significantly longer tool life. That saves money. The Venturi effect keeps the mixture at the cutter at any speeds. This ensures optimal cooling and effectively washes away the chips in milliseconds. Milling of deep pockets and cavities is now facilitated. No tool with internal cooling is needed. Cutters without internal cooling are cheaper and more stable. In summary, this leads to higher process reliability (unmanned work is possible), a longer cutter life, better surface quality, lower tool costs, higher chip removal rates and significantly reduced quantities of coolant and compressed air. The maximum clamping forces of UltraJet™ 3.0 power chucks, the design-related vibration damping properties together with excellent concentricity guarantee maximum chip removal performance in HPC milling with large cutting depths combined with high feed rates and extreme cutting forces.
