Lengthy airfoil machining device, has airfoil support with stationary mandrels mounted on stationary structure by flexible connections, where stationary structure is attached with central column

摘要

The device has a pair of movable mandrels (11) for locking an airfoil and movable along the airfoil, and a displacement mechanism for a tool holder (5) and mandrels. An airfoil support (23) has stationary mandrels (25) mounted on a stationary structure (14) by flexible connections. The stationary structure is attached with a central column. An independent claim is also included for a method of machining of a high length airfoil.
