Problems solved by technology

At present, when using the traditional ball head tool to process the pole head modulation line, due to the defects of the tool itself and the particularity of the pole head modulation line, the corresponding processing accuracy cannot be met, especially the roughness cannot meet the requirements, and the symmetry is out of tolerance. There are many reasons such as the poor consistency of the processing size of the head modulation line, which can easily cause the overall scrapping of the single wing
