The HFECM is mainly applied in the machining of various parts for aerospace field, such as the related structural parts of airframe, turbine engine parts, aerospace fasteners structural plate and pipe. The HFECM can overcome the challenges of difficult-to-machine materials for aerospace industry, tremendously reduce machining cost and increase machining efficiency. Except aerospace industry, the HFECM can also be applied in the bicycle pedal, micro slim tube for precision machinery, medical device with special profile or voice coil motor spring.
