Cutting tool and tooling system specialist Sandvik Coromant is upgrading its long-established CoroCut 1-2 parting and grooving concept. Improved stability, even greater flexibility and significant productivity gains are some of the benefits the new CoroCut 2 system will bring.

CoroCut® 1-2 has long been one of the cornerstones in parting and grooving and the concept’s renowned versatility and reliability has made it a true companion in many a workshop. The concept will now go through a major upgrade and become CoroCut 2.

What can we expect from new CoroCut 2? “For a start, all the features and benefits that you have come to expect from the existing concept — versatility, cost-efficiency and secure machining — are still there”, says Jenny Claus, Product Manager Parting and Grooving at Sandvik Coromant. “We work in close cooperation with our customers sharing our knowledge while trying to listen in and be attentive to their needs and their constructive viewpoints. The result has been overwhelmingly positive.”

Stability is key when working with all parting and grooving operations. The main challenge is to keep the insert in place to minimize all forms of insert movement. The well-established rail interface, previously available on medium and large inserts, provides a more precise insert position and makes the insert resilient against side forces put upon it. This rail interface will now be available also on smaller insert sizes, ensuring stability in all operations.

The CoroCut 2 parting blades are upgraded with internal coolant and an improved clamping finger design, which provides higher clamping force and better side stability, a welcomed advantage when making chamfers before parting off. Tool holders with precision coolant are updated with a screw clamp solution, which — combined with the rigid rail insert seat design — keeps insert movement to a minimum without any clamping force lost.
Other important features included in the upgrade are new and updated grades and geometries, including new first choice grade GC1225, a wiper design for all parting geometries and greatly enhanced edge line quality on all inserts.

“What makes this solution unique is the in-house developed and patented production technology”, says Fredrik Selin, Product Application Specialist at Sandvik Coromant. “With better blank quality from our new production technology, we achieve less spread of the edge line. This means we can have lower tolerance and make a smaller edge rounding than before, with a longer, more predicable insert tool life as a consequence.”

CoroCut 2 can be used in all types of parting and grooving applications with cutting depths suitable for two-edged inserts. Related concepts CoroCut QD and CoroCut® QF are recommended for larger depths of cut, while CoroCut QI is first choice for internal grooving and face grooving on small diameters.
