The C-Frame Panel Assembly Cell (CPAC) is a high performance panel riveting system. The system is one of the best-selling fastening machine concepts world-wide. It is ideal to fasten small to very large sized skin and wing panels. The CPAC achieves fastest cycle times, while maintaining superb component quality. The highly adaptable system can be configured with a flexible fixture tooling to allow high workpiece flexibility as well as easy production process integration.
The CPAC´s compact design and adjustable station layout enables efficient use of precious shop floor space while keeping investment in building infrastructure to a minimum. The C-frame positioning system can be moved and thus maintained independently from the workpiece positioning system. The workpiece can be loaded vertically as well as horizontally.
With more than 50 installations world-wide the system is well proven in production.
