BC Model – The chuck's piston has an inner movement back and forth together with the air feed tube (AFT). This is a safety feature that is required by CE, the European standard. It allows a slight delay after opening and closing of the jaws, before the machine starts its cycle. When the AFT moves forward, the jaws close/clamp the workpiece. Only then, the machine will receive a green light from the proximity sensor to start the cycle.

NBC Model – The Piston movement is internal only. In this model, coolant is available through the chuck body. The chuck is more stable hence rotate on higher rpm.
