The 12 jaw chuck KSA was developed to clamp thin-walled workpieces safely and deformation-free. The well-known FNC quick-change jaw system minimizes set-up time and ensures that this clamping device is also interesting for medium to small batch sizes.
The adjacent jaws are connected to each other so that they clamp in a compensating manner. This allows thin rings to be clamped with a distortion arm.
