Diamond-Like Carbon coating from Sumitomo Electric Carbide aids in the dry machining of aluminum alloys and nonferrous applications. The coating enables cutting tools to maintain their properties, including high hardness, good lubrication, low friction coefficient, smooth surface, corrosion resistance, and longer tool life, even in conditions of harsh-environment cutting. It promotes good chip control and has a low friction coefficient of µ = 0.05 to 0.2, even without lubricants. Aluminum alloy adhesion on the edge is suppressed, thus decreasing cutting resistance. In addition, generation of built-up edge is eliminated, maintaining the sharpness of the edge and improving the quality of the cutting material. Chips are removed effectively, preventing the material from being scratched and preventing deterioration of the machined surface caused by re-adhesion to the cutting material.
