The Forkardt Shaft Chuck (ALZD) allows one continuous turning operation. Its jaws are designed to extend and retract during the turning operation. Chuck jaws are extended to clamp the shaft. As the turning tool approaches the end of the workpiece, the chuck jaws retract, driving the shaft with (3) replaceable carbide drive pins or drive blades. The result is one non-interrupted, continuous turning operation.
This unique design feature is a major advantage over conventional chucks which require two operations and / or two machines to maintain shaft turning production, and can cut your turning operation cost in half.
