The major machining difficulties for a super-large-sized thin-wall hydraulic spindle part were analyzed, focusing on its clamping mode, clamping deformation model analysis and processing flow. Then the processing scheme was proposed. In this scheme, central blocks on both ends and one clamping chuck and two core clampers method were used to process the spindle; after the processing was completed, the spindle was repaired by using one clamping chuck and two support clamping method. By using the scheme, the processing of the spindle is successfully completed and the accuracy requirements are guaranteed. It provides reference for processing similar large-sized thinwall spindle parts.
