Abstract
A method and apparatus for electropolishing a workpiece without immersing the workpiece in a bath of electrolytic solution. The workpiece is held in an atmospheric environment, while electrolytic solution is discharged from a reservoir in the form of a plurality of jet streams onto the surface of the workpiece. A voltage difference is applied across the workpiece and the jet streams, thereby inducing a current to flow, between the workpiece acting as anode and the jet streams acting as cathode. The workpiece may be rotated about an axis and moved linearly along the same axis while the jet streams of electrolytic solution are discharged onto the workpiece. Anodic dissolution causes polishing of the workpiece surface. The electrolytic solution may be collected after discharge and recycled back into the reservoir, after being filtered and cooled.
