KYOCERA develops new industrial cutting tools
Kyocera Corporation has announced that it has developed a new series of hybrid cermet materials offering a 50% improvement in abrasion resistance and fracture resistance over conventional materials used as industrial cutting-tool inserts. The new TN620 and PV720 cermet grades are ideal for a wide variety of metal-cutting applications ranging from high-speed to low-speed machining.
TN620 and PV720 exceed conventional materials in both hardness and strength through proprietary material technologies, such as a special hybrid-structure surface hardening that distributes ultrafine particles within the cermet in a more optimal manner; hybrid bonded phase, including special metal phase with high melting points; and hybrid hard phase with superior compressive stress effects. Furthermore, PV720 builds on the superior properties of TN620 by adding MEGACOAT NANO, a multilayer coating technology never before applied to a cermet.
These new materials expand Kyocera's cutting-tool product line, helping users achieve higher productivity through longer tool life and stable processing of steel components widely used in automobiles and industrial machinery.
