The drawing of the inner wall of the impeller metal shaft generally requires a continuous and cyclical process to ensure uniform groove depth and consistent surface. Most of the conventional grooving machines move in a unidirectional or simple reciprocating manner, are not optimized for annular continuous machining of the inner wall of the impeller shaft hole, and have the problems of low machining efficiency, poor groove body consistency, uneven cutter wear and the like. In addition, because the space of the inner cavity of the impeller is limited, the existing equipment cannot realize stable guiding of the cutter, and the processing quality is further affected.
