DEVICE FOR ELECTROPOLISHING THE INTERNAL SURFACE OF HOLLOW CYLINDRICAL BODIES

摘要

A device for electropolishing the inner surface of a hollow cylindrical body with at least one sponge electrode movable along the inner surface, as well as with devices for guiding the sponge electrode and for supplying the sponge electrode with electrolyte includes a chassis braced against the inner surface of the hollow cylindrical body and being movable along the axis of curvature of the hollow cylindrical body, the sponge electrode being carried by the chassis, being pressable against the inner surface of the hollow cylindrical body and being rotatable about the axis of curvature of the hollow cylindrical body.
