Concentric and eccentric complete machining Concentric and eccentric complete machining in a single clamping set-up? That?s right! With our compact chuck you can turn an eccentric position on the workpiece - in a single set-up without having to re-chuck it! Thus you save time and money. Automatic change-over Change-over from concentric to eccentric takes just a few seconds - it is automatic and convenient due to the setting tool in the turret and the c-axis of the machine spindle. Minimum set-up times and no machine changes whatsoever. And first and foremost: You can use your normal clamping cylinder.
