FRAC

The Frame Clip Assembly Cell (FRAC) is a highly flexible and versatile system for automated drilling and fastening of different aircraft components and substructures (e.g. frame, clips, brackets) with most challenging requirements. Broetje-Automation provides a series of different end-effectors that are tailored to different conditions and requirements to enable highest throughput rates and maximum workpiece flexibility.

FRAC systems are capable to be mounted on stationary or mobile robots as well as other positioning systems. They often combine several different end-effectors (e.g. drill-only end-effectors with automatic tool change combined with drillingand riveting multifunctional end-effectors). The systems therefore reach highest automation levels of more than 90% for all kinds of aircraft types.
