Collet Clamping System SZIf the workpiece to be clamped has only a short clamping base or if the diameter to be clamped has a very large tolerance, system SZ is used.
By applying an axial force a slitted collet is radially expanded by a cone. Simultaneously an axial movement occurs. The workpiece is being clamped.
The illustration on the left shows a cut of the clamping system in the unclamped and clamped mode.
