Sumitomo Advanced DLC Coating
Engineers from Sumitomo Electric Industries, Ltd. have developed an advanced Diamond-Like Carbon Coating (DLC) for the dry machining of aluminum alloys and non-ferrous applications.
Previously, in the first stages of harsh-environment cutting, coatings would peel and lose their beneficial properties. Now, with advanced DLC, cutting tools effectively maintain their properties, including high hardness, excellent lubrication, very low friction coefficient, very smooth surface, corrosive resistance and longer tool life.
The DLC coating promotes good chip control and has a low friction coefficient of µ=0.05 - 0.2 - even without lubricants. Aluminum alloy adhesion on the edge is suppressed even in dry machining, thereby decreasing cutting resistance. Furthermore, generation of built-up edge is suppressed, thereby maintaining the sharpness of the edge and improving the quality of the cutting material. Chips are removed effectively, preventing the cutting material from being scratched by chips and preventing deterioration of the machined surface caused by re-adhesion to the cutting material. The advanced DLC coating can be found on Sumitomo carbide grades, drills, and endmills.
