• Quick change stirrups
• System driven by double cylinder
• High rotation speed

Chuck description

• The system is complete with 2 independent mechanisms.
• First one is moving the central expander having stroke mm7 on diameter, centering the workpiece from the inside.
• Second one is linked to a moving plate driving 3 rotating and stirrupping shafts.
• These are clamping the workpiece granting stiffness during machining.
• Both systems are driven by a double cylinder.
• There is a PEL detection system checking the right positioning of the workpiece by the robot.
• The change of workpiece type is very fast thanks to quick coupling systems of different components.
