This chuck has several features:

- Three clamping jaws

- Orientation pins

- Three stoppers for air pressure monitoring

- A pneumatic ejector

It is a fully automated robot load and unload operation. A robot conveys the workpiece between the chuck jaws and stops at the designated stoppers and orientation

pin. Only when the workpiece is located at the right spot the air stops flowing, then the chuck clamps it. At the end of the operation the chuck's jaws open. The

pneumatic ejector pushes the work piece into the robot gripper.
