More DetailCBN "SUMIBORON" / PCD "SUMIDIA"
>"SUMIBORON" is mainly CBN (Cubic Boron Nitride), a primary component to which special ceramics binder is added and is sintered under extreme pressure and temperature. On the other hand, "SUMIDIA" is a high density sintered diamond compact of ultra-fine diamond particles. Both of these materials have higher hardness and strength, along with excellent heat resistance, as compared to conventional tool materials.
