The Synergy line of indexable carbide turning inserts from American National Carbide is designed to machine challenging, high-temperature alloys such as Inconel. Three chip-control geometries are available for roughing, general-purpose and finishing applications. The AN6105 grade features nano-PVD technology, which can be used at elevated temperatures common to machining superalloys. A proprietary post-coating treatment and edge preparation optimizes chip control while reducing cutting forces, the company says. In field tests, Synergy performed at 175 sfpm and 0.085" DOC with an extended tool life of 20 min.
