Abstract:

According to the results of multiple process experiments, by optimizing the cutter clamping method and milling cutter model, milling cutters with different diameterwere selected at different processing stages, and finally scientific processing technology is developed. The processing quality of the large stopwater groove of the seat ring on the top of tailwater emergency gate groove in the pumping storage power station is successfully guaranteed.
