KYOCERA Releases New MEGACOAT Cermets,
Superfine Cermet Cutting Inserts

Improved wear-resistance, ideal for finishing

October 29, 2008
(This document was translated from the Japanese press release.)

Kyocera Corporation (President: Makoto Kawamura) announced that its Cutting Tool Division will introduce two new cermet inserts that feature greater wear-resistance enabled by Kyocera's proprietary PVD coating system MEGACOAT: the PV7010 MEGACOAT Cermet for machining steel and the PV7005 MEGACOAT Cermet for machining cast iron; as well as the TN6010 Superfine Cermet, which is ideal for semi-finishing of steels.

Cermet is a composite of ceramic and metal, used in cutting tools, which combines the superior heat-resistance of ceramic with the toughness of metal. Cermet has long been used for the finishing of steels, cast iron and other hard materials because of its superior wear- and heat-resistance, and its low affinity with work materials - attributes that ensure high-precision surface machining. Specializing in ceramic materials, Kyocera has continually held the leading market position in the cermet industry.

Kyocera's new cermet inserts feature a unique coating, and the enhanced composition of the cermet surface ensures improved wear-resistance, greater stability in machining, and superior durability. With these features, the new products offer greater productivity in the finishing of hard metals.

MEGACOAT and the Functionally-Graded Cermet

The PV7010 and PV7005 feature the application of the MEGACOAT PVD coating - Kyocera's proprietary technology - that ensures superior wear-resistance and crater wear-resistance. The MEGACOAT also features a higher oxidization temperature - by approximately 200 degrees Celsius compared to conventional products - ensuring superior heat-resistance and stable processing even at high temperatures. The use of MEGACOAT on cermet inserts guarantees stable and high-precision finishing. image:Cutting edge/MEGACOAT/ Base Material

Functionally-graded cermet (PV7010 / TN6010)
The functionally-graded cermet insert features separate material component ratios for the surface and internal structures. The internal is composed of tough cermet that provides superior crack-resistance, while the ultra-hard cermet at the surface offers superb wear-resistance. The PV7010 and TN6010, which both use this functionally-graded cermet, feature exceptional durability for stable processing. Image:left:Innner side of Cermet, Right:Surface of Cermet
   
Features
1. MEGACOAT Cermet PV7010 - ideal for steel finishing
The base material of the PV7010 utilizes a functionally-graded cermet, and incorporates Kyocera's proprietary MEGACOAT on the surface. This ensures superior wear- and heat-resistance. The PV7010 features exceptional hardness while retaining superior wear-resistance, ensuring uniform, high-precision finishing.
 
2. MEGACOAT Cermet PV7005 - ideal for cast iron finishing
The base material of the PV7005 is a special TiC-TiN (titanium carbide / titanium nitride) cermet used for processing cast iron, and also incorporates Kyocera's proprietary MEGACOAT on the surface. This ensures that the wear-resistance is approximately 50 percent greater compared to the company's conventional models. There is also the added benefit of stable processing by suppressing the spread of crater wear - when resistance to the insert causes "chipping."
 
3. Superfine Cermet TN6010 - ideal for semi-finishing of steels
As with the PV7010, the TN6010 uses a functionally-graded cermet as the base material. This provides the new inserts with superior hardness while retaining fracture-resistance, and also permits superior wear-resistance. To correspond to customer's various needs the TN6010 is also available without the surface coating.
