As an important component of the nuclear power equipment,the main pump nozzle connects the reactor coolant pump and the pressure vessel.Due to structural characteristics,boring machine is commonly used to process inner hole and outer circle of the main pump nozzle,and has low processing efficiency.This study designs a special clamping counterweight and optimizes the processing flow,realizes inner hole processing of the long-straight section by using deep-hole drilling machine and outer circle processing of the long end by using lathe,thus greatly improves processing efficiency of the main pump nozzles.
