Two quick-change pallet modules have been introduced by Newport Pagnell-based Schunk Intec Ltd (www.gb.schunk.com).

Among new design features of the Vero-S NSE3 138 quick-change pallet module (pictured) and the Vero-S NSE-T3 138 tombstone module are an optional spring-actuated cone seal that automatically locks the module’s changing interface as soon as the clamping pin is lifted, preventing chips or dirt from lodging there.

The Vero-S NSE3 138 offers a pull-down force of 8 or 28kN for maximum rigidity of the clamping arrangement.

Schunk says that, as a result, high tilting moments and transverse forces can be reliably absorbed when parts are clamped at their base — ready for machining on the top face, for example.

Module clamping and positioning are achieved via a short taper with a repeat accuracy of less than 0.005mm.

Actual clamping is performed via spring force without the need for an external power supply, so workpieces remain safely clamped in the event of a sudden pressure drop in the air system.

A pneumatic-system pressure of 6 bar is sufficient to open the clamping modules.

For process reliability, both the ‘open’ and ‘closed’ clamping-slide positions can be monitored.

All components are made of hardened stainless steel, and the new modules are fully compatible with the existing Vero-S modular system.
