Sandvik Coromant (Mebane, NC) has introduced two new PVD insert grades, GC1205 and GC1210. Both grades enable secure, high-precision turning of aged nickel-based HRSA.
When turning aero-engine components, the surface requirements are high but no longer difficult to achieve, thanks to the new insertgrades GC1205 and GC1210. Together, they cover a large application area within last-stage machining (LSM) and intermediate-stage machining (ISM).
There are several key features that help in working with the high-level performance of heat-resistant superalloy (HRSA) materials. A hard, fine-grained new substrate, the latest physical vapor deposition (PVD) coating technology and optimized edge-line integrity provide increased flank wear and secondary notch wear resistance, superior edge-line security and reduced flaking.
The grades complement each other thanks to an overlap in the assortment. GC1205 is a finishing grade for machined surfaces in LSM and ISM applications. GC1210 complements GC1205 when more toughness is required and is mainly used in ISM applications for nonmachined surfaces.
