Turbo connection
When using the turbo connection (if supply is connected), the
spring actuated locking procedure is actively supported with air
pressure, thereby enhancing the achievable pull down force. One
pressure pulse is sufficient to increase the force. The pressure line
can be decoupled afterwards without the pull-in force being
impaired. If the turbo connection is not used, it must be possible
to ventilate the relevant side of the piston.
Media transfer
The NSE3-A3138-V4-P versions are equipped with four media
transfer units on the bearing surface that can be connected when
depressurized. They can supply the clamping devices with
compressed air, hydraulic oil or vacuum pressure, for example. The
matching NW3 coupling nipples must be installed in the opposite
side to be connected. The transfer interfaces are actuated on the
bottom of the module. O-rings are used to seal the channel bores
against the bearing surface. The NW3 coupling nipples to be used
for the side of the clamping pallet as well as the relevant
installation drawing can be requested from SCHUNK.
NOTE
If the media transfer function is used, ensure that the coupling
elements are depressurized and ventilated when loading and
unloading the clamping pallet. The NSE-A3 138-V4-P1 model has
open media transfer sleeves made of rubber. The interface
drawing for the clamping pallet side can be requested from
SCHUNK.
Before starting the machining process, ensure that the change unit
is resting flat on the bearing surface of the quick-change pallet
system and is locked.
Connecting hose lines
If several quick-change pallet systems are activated via one jointly
connected hose line, feed lines with the following minimum cross-
sections must be used.
