A rotor for polishing hollow tubes, in which an outer tube is slidable over an inner tube and is provided with at least one window in the wall. At the window on the inner tube, a plate vane is fixed at the base end to an auxiliary shaft arranged perpendicular to the main shaft so as to be able to rotationally move. A link bar is arranged in the main shaft direction to extend between the outer tube and the plate vane. The rotor is able to transition between an initial state (plate vane closed) and an operational state (plate vane open) by the inner tube moving relative to the outer tube. An electrode for electropolishing or a buff for mechanical polishing is fixed to the tip end of the plate vane. This allows for adjustment of the position of the plate vane and control of the polished state.

A method of making a light weight component is provided. The method including the steps of: forming a metallic foam core into a desired configuration; inserting a pre-machined component into an opening in the metallic foam core; applying an external metallic shell to an exterior surface of the metallic foam core after it has been formed into the desired configuration and after the pre-machined component has been inserted into the metallic foam core; introducing an acid into an internal cavity defined by the external metallic shell; dissolving the metallic foam core; and removing the dissolved metallic foam core from the internal cavity, wherein the component and the external metallic shell are resistant to the acid.

A method of metal plating components includes placing a component and a spacer on a brochette, placing the brochette with the component and the spacer on a structure, and placing the structure with the brochette into a metal plating tank having a metal plating solution such that the component is submersed in the metal plating solution. The spacer is configured to mask a portion of the least one component and the component and the spacer are arranged on the brochette such that the spacer prevents the portion of the component from being contacted by the metal plating solution. The method also includes metal plating a surface of the component submersed in the metal plating solution, removing the structure with the brochette from the metal plating solution, drying the component on the brochette, and removing the dried component and the spacer from the brochette. Metal plating systems are also provided.
