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.







Mini Precision Air Chuck

This is a mini high precision rotating air chuck with three (3) top jaws suitable for turning applications clamping very small workpiece. The mini air chuck may be mounted on small lathe machine.​
