The Schunk Vero-S quick-change pallet system features a patented dual clamping stroke and an integrated turbo function that provide pull-in force of as much as 9,000 lbs. This high retention force increases the clamping system’s rigidity, enabling considerably higher cutting forces; even extremely high shear forces can be absorbed reliably, the company says. The Vero-S is designed for increased precision, efficiency and process reliability with reduced setup in metal cutting and CMM inspection.

The Vero-S uses one or more clamping pins to clamp workpieces, pallets, clamping stations, existing fixtures and tombstones. Its radial-aligned clamping slide pulls in the clamping pin and locks it. Exact positioning is accomplished via a short taper. Radial location is done via a diamond pin, ensuring a repeat accuracy of at least 5 microns (0.0002"). Holding forces of as much as 16,800 lbs can be achieved. A pneumatic pressure of 6 bars (85 psi) is sufficient for opening the module.

The system is completely compatible and interchangeable with Schunk’s previous pallet systems, and the clamping pins work universally across the line. Workpieces can be transferred from machine to machine or to a CMM accurately and seamlessly, the company says. All functional components of the module are made of hardened stainless steel, including the base body, clamping pin and clamping slide for increased module life and reliability, and reduced maintenance.

The module is completely sealed and protected against the penetration of chips, dust and coolant. An air purge connection is integrated into the standard module and can also be used for part recognition. The position of the clamping slide can also be monitored via an air purge monitoring system. The module also is equipped with bottom and lateral air connections for mounting flexibility.
