  SUMIDIA Binderless Nano-Polycrystalline Diamond ■ General Features Nano-polycrystalline diamond is a type of polycrystalline diamond, produced by directly binding nano-level diamond grains without using any binders. This material is unique to our company, and as compared to conventional diamond grades containing binders, it exhibits higher strength, excellent wear resistance and fracture resistance. SUMIDIA Binderless is the series of tools with cutting edges made from this high performance nano-polycrystalline diamond. ■ Micro-Structure Comparison ■ Hardness Nano-polycrystalline diamond Conventional PCD SEM structure SEM structure Nano-polycrystalline No anisotropy and high hardness Binde（r Co） diamond Single crystal diamond Hardness depends on crystal orientation Conventional PCD Load 4.9 N 100nm 5μｍ 0 50 100 150 Knoop hardness Hk (GPa) Diamond particle average grain Diamond particle average grain diameter (30–50 nm) diameter (1–10 µm) SUMIDIA Binderless ■ Application Examples ● Ballnose Endmill / Radius Endmill (Carbide Machining) M43 ● Indexable Inserts (Carbide Machining) M26 M ● Drills (Ceramics Drilling) ● Cutting Tool (Ultra-precision Cutting of Carbide) SUMIDIA SUMIDIA SUMIDIA Binderless SUMICRYSTAL M4
