At the chuck series CB-NS the collets are engaged in a coupling in the chuck body. Through the forward movement of the drawtube a connected sliding sleeve with cone is moving forward. Thereby the collet makes a radial clamping movement without pull down effect of the workpiece.
The CB-NS series is designed similarly to the CB-ND series. The difference is the smaller construction whereby the chuck is suitable to a 2nd spindle perfectly.
