SUMIDIA Series - General Features SUMIDIA is a polycristalline diamond material developed by using our proprietary technologies. SUMIDIA is available in two grades: DA1000 and DA150, each having different characteristics depending on the size of the diamond grains and the combination of binder materials. In addition, a new grade NPD10 made by nano-level diamond grains without binder material with direct conversion sintering has been newly added to our product line. SUMIDIA can be used for all types of applications, from machining aluminium alloys to brittle materials such as carbide. - Series • Features • Application Average size of TRS Grade Features Application Diamond grains Hardness Hv (GPa) (µm) High density sintered material made of • High Silicon Aluminum Alloy Cutting 110 ultra-fine diamond particles that demonstrates • Rough, Interrupted and Finishing of Al-alloy DA1000 optimum wear resistance, andexcellent edge • Wood or Wooden Board Cutting ~ 0,5 ~ ≈ 2,60 120 SUMIDIA sharpness. • Non-Ferrous Metal finishing (Aluminium, Copper Alloy) Micro-grained sintered diamond grade with • Non-Ferrous Metal finishing (Aluminium, Copper Alloy) 100 strong diamond-to-diamond bonding.
