Kyocera Releases PV7025 PVD-Coated Cutting Tools

Kyocera Industrial Ceramics’ Cutting Tool Division has unveiled its PV7025 PVD-coated cermet grade of indexable cutting instrument inserts for general steel machining.

PV7025 is the latest member of the MEGACOAT cermet portfolio of Kyocera. It features the company’s new in-house MEGACOAT PVD coating technology. The Physical Vapor Deposition (PVD) coating method uses heat and electrical energy to produce chemical reactions such as ionization and fusion for creating a physical coating on the base material’s surface. It delivers remarkable heat resistance and wear resistance, thus offering high durability in super-speed machining. A better cutting tool material for machining steel can be produced by coupling PV7025 with a super micro-grain cermet substrate.

Earlier, Kyocera introduced grade PV7005 for machining cast iron and grade PV7010 for high-speed steel finishing. The company now offers all three grades via a special sales promotion. Kyocera’s MEGACOAT cermet offers various benefits over carbide materials.

MEGACOAT cermets are chemically less reactive when compared to carbide, thus decreasing the propensity for built-up-edge, which in turn offers enhanced surface finishes. They can be operated either dry or wet, facilitating metal chip recycling and decreasing coolant expenditures. Cermet’s stable price is a significant advantage over the increasing price of tungsten carbide.

PV7025 delivers a flexural strength comparable to that of P15 Carbide, allowing it to offer a broad array of federates and cutting depths, from continuous finishing to roughing applications.
