Function 

The VERO-S NST3 clamping station guarantees rapid changing of 
VERO-S tombstones, clamping pallets, devices or workpieces in the 
machine room with a high level of repeat accuracy. In the VERO-S 
quick-change pallet modules, the clamping pallet is positioned and 
locked with a high level of repeat accuracy via the related VERO-S 
clamping pin.  

 

Connections on the clamping station 

The VERO-S clamping station is equipped with an unlocking 
connection and a connection for the turbo function. The air 
connection for each is actuated via a sealing nipple for a quick-
release coupling. The sealing nipple is included in the accessory 
pack for the clamping station. The locking couplings are not 
included in the scope of delivery of the clamping station. The 
required locking coupling required is the industry standard-size 
NW 7.4 (type: VSK Ø10-NW7.4 ID. 1344010 accessory). 

CAUTION

 

The pressure chambers of the quick-change pallet modules must 
be able to vent during actuation.

 

 

•

  When using customer-specific air connection plug-in systems. 

Use sealing nipples without shut-off function (with an open 
through-hole) to vent the clamping module piston chambers. 

 

•

  The corresponding valves, sound absorbers or shut-off valves 

should be fitted with a ventilation function. 

CAUTION

 

When disconnecting hose lines, the relevant air connections 
(sealing nipples) must be closed with cover plates to prevent the 
ingress of dirt or coolant. The attachable cover plates are made of 
plastic and are included in the scope of delivery.
