Ceramic, PcBN, and PCD Inserts Advanced Material Inserts Hard part turning, along with the machining of cast irons, high-temp alloys, and non-ferrous materials, can be accomplished through the use of inserts made from advanced materials. These advanced materials include ceramics, PcBN (polycrystalline cubic boron nitride), and PCD (polycrystalline diamond). WIDIA™ offers: • Improved performance. • Greater wear resistance. • Longer tool life. Ceramic Inserts • Silicon-nitride based ceramic for cast iron machining. • Mixed ceramic for hard machining and finishing of cast iron. • Whisker ceramic for high-temp alloy and hard machining.
