SUMIDIASUMIDIABinderlessFlank Wear Width VB (mm) 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 Grade Features Application Average size ofDiamond grainsHardness Hv(µm)TRS(GPa) High density sintered material made of • High Silicon Aluminum Alloy CuttingDA1000 ultra-fine optimum diamond particles that demonstrates wear resistance, andexcellent edge• Rough, Interrupted and Finishing of Al-alloy• Wood or Wooden Board Cutting110~ 0,5~≈2,60 sharpness. • Non-Ferrous Metal finishing (Aluminium, Copper Alloy) 120 Micro-grained sintered diamond grade with • Non-Ferrous Metal finishing (Aluminium, Copper Alloy)DA150strong diamond-to-diamond bonding.
