Advanced cutting material PCBN
Introduction
Polycrystalline Cubic Boron Nitride (PCBN) is a material which is sintered at extremely high pressure and high temperature into a wear-resistant material with properties close to those of diamond. Due to the hot hardness, oxidation resistance and fracture toughness of the material, inserts made of PCBN have excellent edge strength and long tool life when machining hard ferrous materials and pearlitic grey cast iron. Secomax™ PCBN inserts are suitable for machining: • Hardened steel (including hard-facing alloys) • Pearlitic grey cast iron • Chilled and white cast iron • Manganese steel • Cemented carbide • Powder Metallurgy (PM) alloys For more information including a comprehensive guide to understanding and applying PCBN successfully, please ask your sales representative for the Secomax™ PCBN, Techni- cal Guide (available in English).
Selection of insert type
