Problems solved by technology

[0002] The large-scale rotor support of wind turbines has a complex structure and a huge volume. The bottom of the rotor support is a slope closing structure, and the processing space is small. More than 2,000 threaded blind holes are radially distributed on the inner wall of the arc along the center of the turntable. The number of processes is large and the precision requirements are high. Currently There is no similar accessory head on the market that can meet the demand. The current method of processing is time-consuming and labor-intensive, and the processing efficiency is extremely low.
