Description Universal 3-jaw manual chuck with jaw quick-change system for straight serrated jaws Field of application on conventional lathes on cycle-controlled lathes on mill/turn machines on drill / boring machines on welding systems on special machines Advantages – Your benefits Convenient jaw quick-change system Minimizing set-up times and costs Hardened and extremely rigid base body Therefore a longer life span at highest precision. Even with maximum clamping force Large through-hole Machining of all standard pipe diameters High efficiency of the wedge bar system Process-reliable clamping due to high clamping forces High jaw quick-change repeatability No reboring of already machined jaws necessary Visual safety devices Maximum operating safety Excellent clamping force/torque ratio Perfect use of the machine performance Straight serrated base jaws GBK are compatible to system “R“ (Reishauer) Flexible clamping of small and large workpieces Ergonomic, light safety spanner wrench Ensures easy operation Very easy handling Optimal operator convenience All functional parts are ground and hardened High run-out and jaw change repeat accuracy Options and special information The manual chucks with jaw quick-change system ROTA-G ensure optimum results in workpiece clamping, especially on cycle-controlled lathes. The wedge bar actuation system ensures high precision, run-out and repeat accuracy as well as the highest clamping forces. The large chuck bore makes the machining of raw material with very large diameters possible. By using the quick-change system, no rework of jaws is necessary after jaw change.
