Double Sided Full CBN PCBN Tools Wear Resistant CNC Lathe Inserts for Hard Turning

Description Package Information Inquiry

CBN cutting tools are widely used in modern CNC hard turning industry. Made of high hardness polycrystalline cubic boron nitride material, our CBN turning inserts feature ultra-high temperature resistance, strong anti-wear performance and stable cutting capacity.Suitable for continuous and light intermittent dry cutting, perfectly processing HRC55-68 hardened steel, alloy steel, ductile iron and chilled cast iron. It can replace traditional grinding process, greatly improve production efficiency and reduce processing cost. Various models such as DNGA, TNGA, VNGA, WNGA CBN inserts are available.
