At the chuck series CB-NB the collets are engaged directly in the drawtube connector. Through the operation of the clamping cylinder the drawtube moves axially backward. Thereby the collet is pulled into the cone of the chuck body and result is a radial clamping movement with simultaneous pull down effect on the workpiece.
