With the SPANNTOP combi pull-back chuck with axially mounted base joint base end-stop and the jaw adapter you can now also clamp in front of the chuck. This combination opens totally new possibilities that previously required a jaw chuck.
For example you now can:
- realize considerably larger clamping diameters
- drill or mill in between the jaws.
And don't worry, it won't tip. A clever mechanism will see to that. And speaking of »clever«, you don't even need a changing fixture to insert the jaw adapter. A tapered bolt spreads the segments into the coupling. Removal is in reverse: Unscrew the tapered bolt and you will hold the entire jaw adapter in your hands.
With the aid of the loading plug, the soft jaws can be machined to the required dimension. The jaws have a serration on the back allowing for a 6 mm adjustment of the clamping diameter.
