Ability
Technical characteristics
- check_boxA higher damping results in a longer tool life and a higher capacity.
- check_boxAn ”averaging” of the roughness by lubricant film provides a higher accuracy.
- check_boxExtremely low speed-proportional friction results in no guide faults and no stick-slip effect.
- check_boxMaximum positioning accuracy even for very heavy loads and very short travels.
- check_boxWear-free as no contact when in use results in an eternal lifetime.
