Polycrystalline Diamond
Excellent wear resistance, longer tool life and high-speed, high-efficiency, high-precision cutting of non-ferrous metals and non-metals. SUMIDIA ® is a polycrystalline diamond material made from sintered diamond powder that was first created using our proprietary technology in 1978. SUMIDIA ® ’s superior wear resistance achieves longer tool life in high speed, high-efficiency and high-precision machining of non-metal and non-ferrous metal applications including aluminum, copper, magnesium and zinc alloys. SUMIDIA ® Binderless uses nano-polycrystalline diamond for the cutting edge, demonstrating excellent wear resistance and fracture resistance. In particular, it achieves extended tool life and machining accuracy superior to conventional polycrystalline diamond when machining hard brittle materials such as cemented carbide.
