HELICOPTER DRIVE SHAFTS
—

Because they are long and must be rotationally symmetrical, tail rotor drive shafts are predestined for flowforming. Made of titanium, stainless steel or aluminum and up to 4 meters in length, the shafts have wall thicknesses of 1 – 3 mm and must meet stringent specifications with regard to straightness and concentricity.

HYDRAULIC CYCLINDERS
—

Cylinder tubes and pistons with an integrated piston rod for landing gear cylinders and actuators for doors or other applications are made using stainless steel, such as 15 – 5 PH. The cold forming process reduces material loss by more than 60 % compared to conventional mechanical machining.
