PCD & CBN inserts are widely used in the CNC cutting industry and are a tool material with good development prospects.
PCD (polycrystalline diamond) insert is a combination of diamond material and tungsten carbide, made by high-temperature and high-pressure grinding, polishing and various complicated processes to suitable for various machining. It is suitable for the machining material of non-ferrous metals and composite materials, plastics and the alloy hard to be processed.
CBN (cubic boron nitride) insert is made of boron nitride and tungsten carbide. The hardness is second to PCD (polycrystalline diamond) with excellent chemical stability and don’t have the metal compatibility with iron, cobalt or nickel hence it is suitable for machining hardened steel with hardness above HRC45, and suitable for turning and milling of hard material ferrous metal processing.
