The digital repair line for the nozzle boost regulator of Chengdu Hangli is mainly used in the dynamic control department to meet the needs of information control for materials, processes and quality, inspection and repair, and digital control of key assembly parameters in the repair and assembly process of aircraft engine power components. I hope to further refine production management based on the previous process flow, improve the mode of one person completing the overall repair of the machine, and enhance the quality of manual operations.
