Turning Grade Resists Wear in Inconel 718
Iscar’s IC806 is a Sumotec PVD-coated turning grade for machining high-temperature alloys, especially Inconel 718.
Iscar’s IC806 is a Sumotec PVD-coated turning grade for machining high-temperature alloys, especially Inconel 718. The grade belongs to a family of nickel-based super alloys used extensively for applications where the ability to withstand high temperatures and high corrosion resistance properties are required. The material is widely used in the aerospace industry for engine components as well as in various oil industry sectors.
The grade uses a titanium-aluminum-nitride coating as well as Iscar’s Sumotec coating in order to provide resistance to wear, chipping, notching and breakage while working in Inconel 718, whose high tensile strength can produce very high temperatures on cutting edges. IC806 has a hard submicron substrate with PVD coating and a special post-coating treatment that is said to provide substantially improved tool life and better reliability.
Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
The right choices in tooling and technique can optimize the thread turning process.
Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.
