Kyocera Unveils Cutting Tools for General Steel Machining

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

The 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 the 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. They 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.

The 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.
