The Spanntop System

 The system consists of a flexible

clamping part - the clamping head

and a rigid tube adapter, the

basic body. Both parts are assembled and connected via a coupling, to build one clamping unit. The outer contour of this unit is similar to the conventional spring collet.

The SPANNTOP clamping system

is easy to install into the machine

spindle. The pins of the changing

fixture are inserted into the corresponding holes in the clamping head.

The clamping segments are compressed to engage and disengage the coupling.

To assemble or disassemble the basic body, a installation plug is available . The installation plug provides a solid connection between the spindle and the basic body keyway index.

It is not recommended to assemble the clamping head and basic body directly, without the use of the installation plug as  this may overstress the clamping head.

Changing the Clamping Head (Collet)

 The clamping head is removed or inserted into the spindle, within the

restricted space of the working area, using the compact changing fixture, conveniently operated by hydraulics. The required hydraulic pressure is provided by the pneumatic/hydraulic pressure converter, or where compressed air is not available, an hydraulic foot pump can be supplied.
