Built-in check valve in the chuck body will prevent loosening of the workpiece due to sudden electric power failure. Pneumatic cylinder is built in the chuck body – it is not necessary to attach a cylinder at the end-position of the spindle. Therefore, draw-tube and draw-bar are not necessary and a workpiece can be chucked of the same diameter as the bore of the spindle. High speed is possible when a special air supply mechanism is used.
