Design
Self-contained design with built-in air cylinder. Air is supplied to the chuck by a multi passage air tube assembly with a rotary coupling. Coolant through the spindle capability is standard.

Application
OD and ID chucking for cylindrical grinding, turning, and hard turning. Ideal for workpieces requiring high concentricity, and/or close round ness. Ideal for fragile parts which are easily distorted, and applications requiring high spindle speeds.
