Schunk’s Rota THWplus quick-jaw-change chuck is designed for flexibility and efficiency in setups. According to the company, a complete jaw set can be changed in fewer than 60 sec. with repeatability less than 0.0005", eliminating the need to re-bore jaws. A wedge-bar actuation system enables the chuck to provide larger through-holes with faster spindle speeds. The chuck is available in 165, 185, 215, 260 and 315 sizes. Modular sleeves are available for through-spindle coolant, part ejection, closed-center sealing or adjustable part stop for flexibility.
