Wind turbines generally consist of a tower, wind turbine blades on the tower, a hub, a nacelle, a drive train within the nacelle, a control system, a generator, etc. The wind driven generator blade and the hub are generally connected into a whole through threads, so that an embedded part, namely a bolt, is arranged at the root end of the blade in the blade manufacturing process. Before the blade is connected with the hub, the root end of the blade, namely the end face of the root of the blade, needs to ensure certain precision, namely the whole end face and the embedded part need to achieve uniform precision, and the flatness of the embedded part generally meets the specified requirement through a milling processing mode.

However, because the diameter of the root end of the blade is larger, especially for a high-power wind driven generator, the diameter of the joint surface of the root of the blade and the hub which are in threaded connection reaches more than two meters (even the height of two floors), which increases the difficulty of positioning and processing the end surface of the root end of the blade. Due to the limitation of the blade shape, the conventional end milling machine cannot be used for finishing.
