Sandvik Coromant, a leader in cutting tools and tooling systems, recently launched CoroCut 2 with -RF geometry, designed for secure and high-precision profiling. Additionally, the company introduced grade GC1205 for parting and grooving operations in aged nickel-based HRSA components, offering enhanced process security and consistent tool life.
Sandvik Coromant continues to upgrade its long-established CoroCut 1-2 parting and grooving concept with improved stability, greater flexibility and significant productivity gains.
CoroCut 2 with -RF geometry eliminates the trade-off between chip control and achieving a superior surface finish. This tool provides flawless edge line quality and superb chip-breaking capabilities, ensuring secure machining with high surface integrity results.
“The -RF geometry combines a sharp edge with a high-precision chip breaker, 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 the highest demands from the aerospace industry.”
To achieve superior chip control for small depths of cuts, the chip-breaker geometry must be positioned close to the cutting edge. This is now possible thanks to a unique, patented technology developed in-house. With this innovation, the chip breaker can be placed precisely where it needs to be to get the job done — while maintaining a sharp insert edge.
“With the -RF geometry, you can expect top process security, even in the most challenging materials,” says Selin. “The -RF geometry also offers superior tool life due to the new technology, which results in higher quality and more consistent performance.”
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 PVD coating technology and optimized edge-line integrity, providing increased flank wear and notch wear resistance, superior edge-line security and reduced flaking.
“For our customers, this translates into possibilities to run the inserts at higher cutting speeds, and additionally it ensures consistent and predictable tool life while reaching the required surface integrity demands for critical aerospace components,” says Martin Saunders, global product application specialist for turning at Sandvik Coromant.
Another important factor for all parting and grooving applications is stability. The main challenge is to keep the insert in place to minimize all forms of insert movement. The solution is Sandvik Coromant’s well-established rail interface, which provides a more precise insert position and makes the insert resilient against side forces put upon it, ensuring stability in all operations.
