The company’s high-precision power chucks (PPC) feature a dual actuator design to provide increased clamping force and higher rpm capability. The design is said to achieve greater rigidity, resulting in improved accuracy at high draw tube forces. Increased chuck life is also said to be attained because the internal clamping load is distributed over twice the surface area compared to the original PPC design. The company’s QC precision jaw locating system is standard on all PPC-D models. This system maintains 0.0002" (0.005-mm) maximum workpiece runout after jaw change without remachining top jaws. The collet chucks feature a vulcanized design for reduced chuck length to provide greater rigidity and higher clamping force with standard accuracy within 0.0004" (0.010 mm) TIR. Also on display are dead length, pullback, low-profile subspindle and self-contained, front-actuated models.
