Description

Technical Field

[0001] The present application relates to the technical field of wheel hub cleaning, and in particular to a device for online cleaning of impurities such as residual aluminum chips and emulsion on the surface of a wheel hub, and specifically to an online wheel hub cleaning system. Background Art

[0002] After the wheel hub is machined, aluminum chips and emulsion will remain on the surface of the wheel hub.
