DESIGNER JAWS INCREASE EFFICIENCY IN FINISH MACHINING The intelligent jaw design of the Schunk UVB-HS soft chuck jaws defines a new class of efficiency in lathe chuck technology. With a combination of overheight and angle cutting, it achieves a whole bundle of efficiency effects during finish machining of workpieces. The unusual jaw height allows for a larger clamping surface on the workpiece, which reduces deformations. Alternatively, the distance between the workpiece to the chuck face can be increased and thus accessibility can be optimized. In comparison to conventional monoblock jaws, Schunk UVB-HS reduces the jaw weight by up at least 20% depending on the size. This increases energy efficiency and shortens the processing time, since the lathe chuck can be accelerated and braked faster. At the same time, the reduced jaw centrifugal force allows for higher holding forces on the workpiece, which means increased process reliability.
