Document Type and Number:
WIPO Patent Application WO/2019/066584
Kind Code:
A1
Abstract:
One embodiment relates to an electrode frame for electropolishing and an electropolishing apparatus comprising same. The electrode frame for electropolishing, according to the embodiment, is an electrode frame used for an electrolytic cell having provided therein a receiving space for receiving an object being electropolished and an electrolyte, wherein the electrode frame may comprise: an electrode holder member coupling to at least one protrusion part of the object being electropolished; and a first cathode frame having a grid structure and having at least one side thereof coupling to the electrode holder member so as to be spaced apart at a predetermined distance from an electropolishing surface of the object being electropolished. The electrode holder member may comprise: a first surface coupling to the protrusion part of the object being electropolished; and a second surface coupling to the first cathode frame. The electrode holder member may be coupled to the protrusion part of the object being electropolished without having to use a tap hole.
