DLC SDC

  • DLC Coat
  • SUMIDIA Coat

Super smooth AURORA Coat reduces adhesion and provides good surface finish. Our original polycrystalline diamond coating technology achieves

  • Low milling resistance enables high feed machining and over 10 times higher wear resistance than uncoated carbide. milling of low rigidity works. Realising fine diamond coating that provides both high strength and Perfect for machining non-ferrous metal/copper electrodes high wear resistance with smooth surface required for CFRP milling.
