Quick change collet vice CB-NRB, axially moved collet

At the vice series CB-NRB the collets are engaged into the piston. At operation of the integrated clamping cylinder the piston moves axially backward. Thereby the clamping head is pulled into the cone of the chuck body and result is a radial clamping movement with simultaneous pull down effect on the workpiece.

For the pneumatic operation there are pressure booster units in the ratio 1:2 or 1:4  available.
