The Rota THW Plus quick jaw-change chuck from Schunk is designed so that a complete jaw set can be changed in less than 60 sec. with a repeatability of less than 0.0005", eliminating the need to re-bore jaws. A unique wedge-bar actuation system enables larger through-holes with faster spindle speeds. According to the company, the chuck increases time in the cut, not in the setup, maximizing the throughput and return on investment of virtually any lathe.

A selection of modular sleeves are available for through-spindle coolant, part ejection, closed-center sealing or adjustable part stop, providing flexibility in all process improvements. The chuck is available in sizes 165, 185, 215, 260 and 315.
