Abstract: The present invention concerns a method and an arrangement for processing calcinated carbon bodies such as anodes or cathodes for use in connection with electrolytic production of aluminium. The carbon bodies are processed using a rotating processing tool (101) that consists of a mainly circular disc with cutting edges (114) mounted at its periphery. The cutting edges may be made of polycrystalline diamond (PCD) or an equivalent material. The rotating processing tool mounted on a rotating, driven spindle and is guided by guiding elements (110) that can be jets or perforated discs that blows pressurized air at the tool, or rollers (120). With the present invention it is possible to create narrow and deep slots in calcinated carbon bodies in an efficient manner with low tool wear.
