Machining the wing rib

Drilling, finishing and roughing aluminium alloys with a high chip removal rate and a long service life

Together with the stringers, the wing ribs form the framework of the aircraft wings and are permanently exposed to enormous stresses while in the air. To save weight and counter the constant stress, aluminium wrought alloy has become the go-to material for wing ribs.

Our process-secure tooling solutions are designed to cope with high-speed machining operations and deliver outstanding parameters in machining processes.

1. MaxiMill HPC/HSC indexable insert milling cutter

High-speed milling

90° shoulder milling system for roughing and finishing light alloys
