Sandvik Coromant Parting, Grooving Concept Improves Stability, Chip Control

Sandvik Coromant’s CoroCut 2 with -RF geometry is designed for secure and high-precision profiling. Additionally, the company recently introduced its GC1205 grade for parting and grooving operations in aged nickel-based heat-resistant superalloy (HRSA) components, offering enhanced process security and consistent tool life.

Sandvik Coromant says its CoroCut 1-2 parting and grooving concept features improved stability, greater flexibility and significant productivity gains. CoroCut 2 with -RF geometry eliminates the trade-off between chip control and optimized surface finish. This tool can provide enhanced edge line quality and chipbreaking capabilities, enabling secure machining with high surface integrity results.

“The -RF geometry combines a sharp edge with a high-precision chipbreaker, making it ideal for finishing operations in ISO S materials, where chip control can be an issue,” says Fredrik Selin, product application specialist at Sandvik Coromant. “With this tool, we can meet high demands from the aerospace industry.”

To enhance chip control for small depths of cuts, the chipbreaker geometry must be positioned close to the cutting edge. It is said to maintain a sharp insert edge with extended tool life in challenging materials.

Insert grade GC1205 is the most recently developed grade for machining aged nickel-based HRSA materials. It features a hard, fine-grained substrate, the latest physical vapor deposition (PVD) coating technology and optimized edge-line integrity, providing increased flank wear and notch wear resistance, edge-line security and reduced flaking.

Additionally, Sandvik Coromant’s rail interface can provide precise insert positioning and make the insert resilient against side forces put upon it, enabling stability in all operations.
