Adaptability is made simple with pneumatic compliance for robotic surface finishing

Compliance devices ensure smooth, uninterrupted production by compensating for fixture misalignments, positioning errors, shifting parts and part tolerance variations.

Using passive, air-pressure-based compliance, these tools maintain consistent surface contact even on curved or irregular geometries. This significantly reduces programming effort and tight tolerance requirements.

The built-in compliance mechanism adapts to variations in part geometry and robot path, improving surface finish quality, extending abrasive life and minimizing setup time.
