edited by Bernard Martin It’s been estimated that a tool with a run-out of 50% of the tool’s chip load will reduce its tool-life by 40%. That means that a 1/8” tool with a 0.00019” chip load per tooth will lose 40% of its tool-life with a run-out of less than 0.0001”.

HORN’s new high performance coatings IG6 and SG3 are a testaments to engineering expertise in tool manufacturing.  Horn USA Carbide Grade IG6: More performance in the machining of steel and stainless steels. The new coatings are less than 0.005 mm (.0002”) thick and an essential part of modern tool technology. Testing has shown that the new tool coatings extend the service life of carbide tools by over one-thousand percent. 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 allows for faster material removal rates and significantly extended wear resistance in machining materials P and M. Standard inserts are available from stock.  Horn USA Carbide Grade SG3. The choice for machining hardened steel and difficult-to-machine materials. SG3 is designed for use in titanium and super-alloys as well as turning and grooving applications in hardened materials, up to 58 HRC. The coating can be function in temperatures up to 1,100 degrees Celsus (2,012 degrees Fahrenheit). HORN designed this coating to deliver outstanding performance with materials that are difficult to machine. The advantage of the tool coating have been proven on selected tool systems from HORN. The Supermini® system 105 with SG3 coating is available from stock. In both cases, the IG6 and SG3 coatings are applied in-house, allowing for reduced delivery time. HORN has developed a high level of expertise in coating precision tools since it began in-house coating processes. From five employees in the beginning to more than fifty employees, the aim has always been to create and invest in modern coating technologies for precision cutting tools.
The HORN team was the first in the world to take delivery of HiPIMS systems from CemeCon. The opportunities to develop hard and tough coating with a homogeneous structure has provided this team the flexibility to create advancements that benefit customers who demand precision tools in demanding applications. |
