The RS Line of the centering vices of the company DERO
Feinmechanik AG are specially developed for precision
grinding, wire cutting EDM, die sinking EDM and various
measuring operations.
The centring vices have been developed for use on 5- axis
machining centres such as
CNC- milling machines for the individual
part clamping and for the individual part clamping and for
pallet clamping on clamping systems.
The special feature of the centering vice is the central
clamping which is achieved with a spindel with right and left
thread.
User guide
The centering vice can either be clamped to the machine table
on the laterally circumferential groove with clamping claws.
For positioning holes and threads are attached to the bottom.
Customized holes and threads on the underside of the centric
clamp are also available for mounting. For tightening and
loosening the centric clamp it is recommended to use a torque
wrench. A process-safe voltage can only be guaranteed by
tightening with a torque wrench.
