Precision clamping chucks

Stainless hand-operated chuck

All chucks of this type are made of stainless steel. The chucks are built to be flat and light. A large adjustment range, good concentricity (<0.02mm) and high repetitive clamping accuracy (<0,005mm) guarantee excellent quality in production. Opening and cleaning of EDM residue and other dirt is extremely done quick and simple. The hardened standard clamping jaws are reversible. The adjustment of the chuck is done by turning the clamping ring. Thus a fast clamping can be done by hand - without the need for any additional tools.
