Abstract (en)
[origin: WO2010023226A1] Device for polishing centrifugal impellers (2) for a turbomachine compressor, comprising a tank (8) intended to be filled with a polishing agent, an impeller support (10) able to turn the impeller (2) about its axis and move it along its axis so that all points of the impeller (2) are moved in a helical path the pitch of which is similar to that of the helix from which the overall shape of the airstreams of the impeller, delimited by the impeller blades, is derived.
