Our expertise can provide optimum solutions in the Aerospace Industry for the following products Drive Shafts for Jet Engines Drive Shafts for Helicopters Aero - Hydraulic Cylinders Accumulators, Pressure Vessels Aviations & Space Drive Shafts for Jet Engines Forming of shafts in the hardened condition to the finished part’s dimensions eliminates the otherwise-present distortion when tempering and drastically reduces the costs for balancing. The high precision of free flow forming technology permits the design of wall thicknesses very close to the theoretic minimum with the result of lowest component weights and imbalances. Tempered steels of all kinds and highly temperature-resilient Drive Shafts for Helicopters Tail rotor drive shafts made of titanium, stainless steel or aluminum are predestined components for flow-forming procedures. The shafts are up to 4 m long, have a wall thickness of 1 – 3 mm and pose high demands to straightness and concentricity. The precise flow-forming procedure permits producing these shafts with a wall thickness tolerance of less than 0.05 mm and a concentricity of inner- to outer diameter of less than 0.03 mm. Different wall thicknesses within a shaft can be implemented easily in material utilization of up to %97.
