Standardized pendulum jaws from SCHUNK enable cost-efficient and safe clamping of thin-walled workpieces that are prone to deformation. The pendulum jaw consists of a supporting jaw with bearing bolts, a pendulum body and clamping inserts. To clamp another workpiece diameter, the pendulum bodies are simply exchanged. The delivery unit comprises 1 piece.
Full grip jaws made of aluminum are used for machining sensitive workpieces. The large bearing surface ensures that clamping forces are evenly distributed over the workpiece area, thereby reducing deformation of the workpiece. The delivery unit comprises 1 set = 3 pieces.
QUENTES fiberglass jaws provide a powerful hold with maximum surface protection. The clamping inserts are made of glass fiber-reinforced plastic, enabling a high coefficient of friction of approx. 0.3 to 0.4, and therefore prevent the formation of clamping marks on the workpiece surface. Set-up is done without a trace. The delivery unit comprises 1 set = 3 pieces.
The jaw quick-change system RAPIDO enables jaw changes in a matter of seconds without any use of tools whatsoever. It reduces the set-up time of a complete set of jaws to less than 60 seconds. Different clamping diameters, unmachined and finished parts can be clamped in the shortest of times in a reliable process. User-friendly handling even with overhead hanging lathe chucks as well as easy set-up without having to readjust the jaw. Due to the ground interfaces, the system attains a change repeat accuracy of max. 0.02 mm. The double locking ensures maximum security even in unclamped state. RAPIDO can be used both on a SCHUNK chuck with a corresponding interface, as well as retrofitted on an existing lathe chuck using an intermediate jaw.
