TYPE CCL-ST
AUTOMATIC DEVICE ALLOWING THE CENTERING OF WORKPIECE ON HOLE, BY MEANS OF LONG STROKE EXPANDER (7MM ON DIAMETER) AND MOVING STIRRUPS

MAIN FEATURES
• Centering clamping on hole and stirrup
• PEL workpiece detection system
• Long stroke expander (7 mm on diameter)
• Repeatability accuracy lower than 0,005 mm
• Quick change centering
• Quick change stirrups
• Quick change rest
• 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 mm 7 on diameter, centering the workpiece from the inside.
Second one is linked to a moving plate driving 3 rotating and stirruping 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.
