5 Use and limits of use
5.1 Use
The product is a clamping device that may only be used to
clamp a rotationally symmetrical workpiece to enable it to
be machined.
As well as for its general field of application, this product
was designed and developed for use, when necessary, in a
specific and documented application [see clamping situa-
tion drawing or order confirmation].
Any other fields of application require the explicit approval
of the manufacturer.
The clamping device can be used as an end-stop chuck. For
this, a workpiece end-stop can be mounted.
The clamping device can be used as a through-chuck for
machining bar stock.
5.2 Limits of use
Limits are set on the operation of jaw chucks in the area
where workpieces are machined.
