QUANTITY

Jaw Quick Change in less than 60 seconds

Universal 3-jaw manual chuck with jaw quick-change system for straight serrated jaws.

Share

Definition clamping force
The clamping force is the arithmetic sum of the individual forces occuring at the chuck jaws, distance “H“ at maximum pressure and maximum torque. The specifications exclusively refer to the grease used by SCHUNK.

  • 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

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.
