Sandvik Coromant, a global leader in metal cutting tools and solutions, is expanding its versatile parting and grooving concept, CoroCut® 2. The expansion includes the introduction of the new parting and grooving geometry -GL and the updated parting-off geometry -CR, offering benefits such as increased chip control in long-chip material and a strong edge for high-feed parting-off.
Sandvik Coromant continues to develop its long-established parting and grooving concept CoroCut® 1-2, known for its high performance and security across versatile applications. By increasing productivity and overall efficiency, CoroCut® 2 maximizes output while minimizing energy consumption and waste. While modest in scale, this update will make a significant difference to workshops machining in hard-to-chip steels and parting-off operations where a strong edge is needed.
Featuring the most aggressive chip breaker in the CoroCut® 2 concept, the new -GL geometry is a welcome addition for workshops requiring better chip control in demanding ISO P components, specifically in low-carbon steel, clean steels and cold-forged automotive components. “It’s no secret that good chip control will help you boost efficiency and avoid costly machine stops, but not just any insert will master this kind of material,” says Jenny Claus, Product Manager Parting and Grooving at Sandvik Coromant. “This geometry has been developed to solve that problem.”
The -GL geometry provides security that paves the way for increased automation. Jenny Claus continues, “Shorter chips lead to less tangling and fewer stops, minimizing the need for manual handling and enabling more automated processes.”
The -CR geometry is the first choice for parting-off operations at higher feeds or during intermittent cutting, suitable for a wide range of materials. With its strong edge and wiper design, it increases productivity and ensures excellent component quality. “All our parting geometries feature this wiper design. It allows you to machine components at high feed rates without sacrificing surface finish and chip-breaking capabilities,” says Fredrik Selin, Product Application Specialist at Sandvik Coromant. “A general guideline is: Two times the feed rate, same surface finish. Same feed rate, twice as good surface finish.”
When it comes to parting and grooving operations, stability is key. The main challenge is to secure the insert to minimize any movement. Both the -GL and -CR geometries feature the well-established rail interface, ensuring a more precise insert position and reducing movement for enhanced stability, especially when side forces are applied. Additionally, both geometries are produced with our patented FlashLight technology, generating higher quality and a more consistent edge line, resulting in superior and predictable tool life.
