Surface Finishing of Rotor Blades for Wind Turbine

A method for surface treatment of a rotor blade for a wind turbine, the rotor blade comprising a leading edge and a trailing edge separating substantially opposing first and second surfaces of said rotor blade, the method comprising the steps of:

• providing a rotor blade and supporting said rotor blade at least at a root end and at a distal position along a longitudinal axis of the rotor blade, wherein a supporting member at the root end is arranged to prevent rotation of the rotor blade about the longitudinal axis of the rotor blade,
• providing a moveably arranged first surface treatment device adapted to provide surface treatment of the first surface of the rotor blade, and
• providing a moveably arranged second surface treatment device adapted to provide surface treatment of the second surface of the object,
• wherein the first and second surface treatment devices are moved in opposite directions and towards the leading and trailing edges, respectively, during surface treatment of the first and second surfaces of the rotor blade.
