Center of excellence in turbine blade machining and treatment

Safran Transmission Systems is specialized in the machining of turbine blades for the CFM56-7 and LEAP.

Safran Aero Boosters selects Safran Transmission Systems to make turbine blades.


These precision parts are supplied as cast stainless steel pieces. The first step is to mill the two ends of the blades, the tip and root, and then apply chemical and heat treatments.

Each of the 100,000 blades produced yearly for the CFM56-7 is subjected to visual checks, non-destructive tests and 3D dimensional inspections to ensure full user satisfaction.

Safran Transmission Systems is now setting up a new blade machining and treatment line for the new-generation LEAP turbofan engine.
