SCHUNK Launches VERO-S NSP 140

SCHUNK Launches VERO-S NSP 140

Powerful pallet change module with comprehensive monitoring options

Following the successes of its high-performance pneumatic SCHUNK VERO-S series quick-change pallet systems, SCHUNK has launched a hydraulic clamping module for machines with pallet changer that combines compact dimensions, high pull-down forces, an integrated lifting function, and a complete monitoring function.

With a diameter of 138 mm and a height of just 37 mm in the change pallet, the fully sealed SCHUNK VERO-S NSP  140 has an extremely compact, so that it can be also used for thin change pallets. It has a huge pull-down force of 45,000 N. Together with its solid screw connections (8 x M12), it offers ample potential for demanding machining operations.

In order to ensure maximum process reliability during the automated pallet change, the module comes standard equipped with a pallet system control, clamping slide monitoring for querying the clamping state, as well as a cleaning function for the contact surfaces.

High lifting forces due to hydraulics

In the NSP-S 140 version, the piston stroke is additionally monitored via sensors. 5.5 mm high lifting of the pallet and optional precentering also ensure process-reliable pallet changes in combination with media transfers. The lifting force is 15,000 N per module, the repeat accuracy is less than 0.005 mm.

Clamping rings in flange design (Ø 148 mm, installation depth 23 mm, height as of pallet 14 mm) shorten the alignment process for the pallets, and reduce pallets costs. The module is actuated at a hydraulic pressure of 25 bar.

SCHUNK Releases Versatile Clamping Module For Automated Machine Loading

SCHUNK Releases Versatile Clamping Module For Automated Machine Loading

SCHUNK’s VERO-S NSE-A3 138 clamping module is specifically designed for automated machine tool loading as well as for applications in handling, assembly and automation technology. The module is part of the extensive SCHUNK VERO-S modular system, which enables more than 1,000 possible combinations for efficient workpiece clamping.

For reliable workpiece and clamping device changes, the automation component is equipped with a powerful blow-off function, which carefully cleans the bearing surface during the changing process. In addition, a spring-actuated cone seal prevents chips or dirt from penetrating into the interface.

VERO-S NSE-A3 138 features a pull-down force of 8,000N or 28,000N with activated turbo function, as well as a high dimensional stability of the module body, providing rigidity in automated quick-change solutions.

Depending on the application, the modules can be combined in any quantity. Centring inserts with flexible elements ensure positional orientation with a high repeat accuracy and maximum process reliability in automated operations. The repeat accuracy is <0.005mm.

The actual clamping is done without any external energy supply via spring force; it is form-fit and self-retaining, ensuring the workpieces remain safely clamped in the case of a sudden drop in pneumatic pressure. A pneumatic system pressure of 6bar is enough to open the module.

If the modules are used individually, a standard integrated anti-twist protection ensures a stable position in the highest configuration. Through its integrated media transfer, fluids with permissible system pressures of up to 300 bar can be transferred, for example, to control clamping devices using Plug & Work or to supply components for automated monitoring.

As part of the VERO-S modular system, the automation module benefits from a variety of combination options—from standard plates to SCHUNK TANDEM clamping force blocks to mechanical vises from the SCHUNK KONTEC series.
