Overview
The Multi Panel Assembly Cell (MPAC) by Broetje-Automation GmbH is an advanced automated fastening machine designed for assembling large aircraft components such as wing covers and fuselage panels. It offers maximum flexibility and high throughput, making it ideal for large-scale manufacturing processes.
Key Features- Sensoric system for detecting fastener position, distance, normality, workpiece zero point, tack-rivet detection, countersink, head height, and sealant application.
- Siemens NC Controls with 10 axes for precise positioning.
- Optional features include slug fasteners, drill and trim, collar installation, and a lower tool changer.
- Minimal Quantity Lubrication System (MQL) and BA Lube for efficient operation.
- All components are accessible from floor level, eliminating the need for platforms.
- 180-degree fastening capability with an all-electric fastening system (AEFS).
- High-speed tool changer for drill bits and upper anvils.
- Automated fastener feeding system (AFFS) for increased efficiency.
