Machining the wing rib

Material removal rates and tool life stats reach new heights

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 reduce the weight and ensure durability, wrought aluminium alloys have become the go-to material for wing ribs.

Tool solutions from CERATIZIT with a high degree of process reliability make high-speed machining with outstanding parameters possible.
