Abstract

The present invention concerns a method and a device 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 (1) that consists of a mainly circular disc with cutting edges (12, 12') mounted at its periphery. The cutting edges may be made of polycrystalline diamond (PCD) or an equivalent material. With the present invention it is possible to create slots in calcinated carbon bodies in an efficient manner with low tool wear.
