Abstract: The principal axis is the most important rotating and transmission part in hydro-generator unit. Combining with the principal axis structure of suspension type hydro-generator, this paper analyzed this type of processing difficulties and improved processing technical from the respects such as processing equipment selection, technological process arrangement, processing cutting tool and auxiliary frock tool. Compared with the old technology, it shows that the new one solves the difficulty of principal axis processing of more suspension type hydro-generator unit, which ensures the workpiece processing quality and reduces the workpiece deformation maximumly.
Key words: suspension type hydro-generator; principal axis; deflection; processing measure
