CoroCut 2 parting and grooving

Share This Post

Sandvik Coromant is upgrading its established CoroCut 1-2 parting and grooving concept.

The company says the new CoroCut system offers improved stability, greater flexibility and significant productivity gains.

“For a start, all the features and benefits 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 striving to listen 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 keeping the insert in place to minimize all forms of insert movement. The well-established rail interface, previously available on medium and large inserts, offers more precise insert positioning and makes the insert resilient to any lateral forces exerted on it. This rail interface will now also be available on smaller insert sizes, guaranteeing stability in all operations.

CoroCut 2 parting blades are upgraded with internal coolant and an improved clamping finger design, which offers a higher clamping force and better side stability — an 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 loss of clamping force.

Other important features included in the upgrade are new and updated grades and geometries, including the 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 spreading of the edge line. This means we can have a lower tolerance and perform 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 double-edged inserts. The related CoroCut QD and CoroCut QF concepts are recommended for larger depths of cut, while CoroCut QI is the choice for internal grooving and face grooving on small diameters.
