Automatic clamping takes place over disc springs, which are adjustable in the pre-loading and are solved pneumatically to the workpiece change. Manual clamping is made by a knurled knob on the opposite side of the collet. Due to the integration into the existing through-hole of the rotary table, the rotary table with the clamping system remains very compactly.
