Assembly Assembly General Installation Notes Pre-assembly measures Lift the quick-change pallet system carefully out of the packaging (e.g. using suitable lifting equipment). Eye bolts are supplied for transporting the clamping station. The eye bolts are to be mounted into the transport threads on the base plate and then removed after assembly. -
Page 20: Alignment Using Alignment Elements
Assembly Alignment using T-nuts 4.2.2 Alignment using alignment elements The clamping station can be mounted on the machine table via a centering pin for the center bore. The clamping station is aligned at an angle in a suitable alignment hole or alignment groove of the machine table via an adjustment pin, an adjustment pin with alignment width or a T-slot, and all six degrees of freedom are completely fixed. -
Page 21: Mounting And Connecting The Clamping Station
Assembly Mounting and connecting the clamping station To prevent chip accumulation, a sufficient number of protective covers for covering the mounting screws is provided in the accessory pack. WARNING Risk of injury due to brass bore hole cover plate ejecting during a turning application of the clamping station. - Page 22 Assembly ensure secure mounting, the clamping station must be fastened on the machine table at all possible mounting points. With the NST3 500-300, the clamping modules mounted must be removed prior to assembly in order to make the outer mounting locations accessible.

Assembly Number of clamping modules Min. nominal hose width (hose installed internal diameter) 6 mm 8 mm When decoupling hose lines, the pneumatic plug-in connection or the sealing nipple must be protected against the ingress of dirt or cooling lubricant. The sealing nipple comes with a plastic cover plug. -
Page 24: Nst3 500-300
Assembly NST3 400-250 4.3.2 NST3 500-300 The clamping station is mounted on the machine table with screws size M16 according to DIN EN ISO 4762 10.9. The mounting locations can also be screwed using M12 screws and suitable washers. There are two alignment grooves on the bottom of the clamping station for mounting loose T-nuts to be used for aligning the clamping stations. - Page 25 Assembly Note: The access to the outer mounting locations requires all four quick- change pallet modules to be disassembled. After the assembly of the clamping station, the modules have to be installed again with the required tightening torque. The scope of delivery includes new cover flaps for closing the fastening screws of the clamping modules.

Page 28: Information To Clamping Pin Spg 40
Assembly Clamping pallet with 4 clamping areas 4.4.1 Information to clamping pin SPG 40 Instead of the SPA 40, the SPG 40 can be used with a clamping area. The repeat accuracy increases to < 0.002 mm when using the SPG When connecting the screws from above, according to order preference 2, an M12 screw 10 mm longer of strength class 12.9 must be used. -
Page 29: Vero-S Tombstones (Optional)
Assembly VERO-S tombstones (optional) Suitable VERO-S tombstones are available as accessories for clamping stations. There are different sized tombstones that correspond to the clamping stations. These are available in the pallet sizes 400 x 400 mm and 500 x 500 mm. The tombstones can be equipped with VERO-S zero point clamping pins, thus achieving a highly precise change-repeat accuracy together with the clamping station. -
Page 30: Screw Tightening Torques
Assembly Screw tightening torques Tightening torques for mounting clamping pins to the workpiece or to the clamping pallet. (Screw quality 12.9) Screw size M10 M12 M14 M16 Tightening torques (Nm) Tightening torque for mounting the clamping station and for reinstalling clamping modules with fixing screws DIN EN ISO 4762. -
Page 31: Function
Function 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. -
Page 32: Unlocking Connection
Function Unlocking connection If the unlocking connection on the clamping station is pressurized with compressed air, all modules are unlocked simultaneously. Tombstones, clamping pallets, devices and workpieces can be exchanged or removed from the clamping station. Since VERO-S NSE3 clamping modules are spring-operated clamping systems, the connection must remain pressurized with compressed air (at least 5 bar) during the set-up / changing process. -
Page 33: Turbo Connection
Function TURBO connection The clamping stations are equipped with an additional turbo connection. When compressed air is applied at the connection for the turbo function, this function actively provides air pressure to support the spring-actuated locking procedure of the quick-change pallet module. -
Page 34: Vero-S Connecting Strip Asl2-G1/8" (Optional)
Function VERO-S connecting strip ASL2-G1/8” (optional) Upon customer request, a VERO-S connecting strip type ASL2 G1/8" can be mounted to the clamping station in order to facilitate access to the air supply points. The connecting strip is equipped with an elevated connection point with two size NW 7.4 sealing nipples. -
Page 35: Operation
In this case, the system must be inspected and damaged parts must be replaced immediately. Only original SCHUNK spare parts may be used! WARNING Risk of injury due to losing pallets or workpieces in the case of incorrect actuation caused by incorrect operation. -
Page 36: Maintenance And Care
Risk of injury and risk of damage to the clamping module when opening the housing cover. If the clamping module has to be disassembled, send the module to SCHUNK for repair. The covers of the clamping modules are spring preloaded and may only be removed by trained specialist personnel. The... -
Page 37: Leak Test
Maintenance and care • During maintenance work on the quick-change pallet modules or the bottom air supply of the clamping station, new seals must be fitted and lubricated with Renolit HLT 2 or a similar grease before assembly. • Check the supply hose line to the pressure supply of the clamping station for damage at regular intervals. -
