Horn has developed hard and tough coatings with homogeneous structures designed to offer improved cartridge tooling system performance. The company says its IG6 and SG3 high-performance coatings can extend the service life of carbide tools by over 1,000%. These coatings are less than 0.005-mm (0.0002") thick.

IG6 is a copper colored aluminum-titanium-silica nitride (AlSiTiN) coating designed for use in machining materials P and M with grooving inserts type S224 and S229. In conjunction with the carbide substrate, the coating enables faster material removal rates and significantly extended wear resistance in machining materials P and M. Standard inserts are available from stock.

SG3 is designed for use in titanium and super alloys as well as turning and grooving applications in hardened materials, up to 58 HRC. It is said the coating can function in temperatures up to 1,100°C (2,012°F). This coating was designed to deliver outstanding performance with materials that are difficult to machine, the company says. The Supermini system 105 with SG3 coating is available from stock. In both cases, the IG6 and SG3 coatings are applied in-house, which reduces delivery time.
