Flaps provide the necessary lift to the aerofoils during aircraft landing and are located on the rear edge of the aerofoils.

Various materials are used in the manufacture of flaps. The flap track may consist of 15-5 PH stainless steel, Carpenter C465 or titanium 6Al-4V. In newer aircraft, titanium/aluminium or CFRP/titanium combinations are also used.

The machining (pocket and contour milling) is generally carried out on CNC mill centres or multi-spindle portal milling machines. Our Tiger•tec® Silver PVD tools are the right tools for long tool life and optimal dimensional stability.​
