Sandvik Coromant's updated CoroCut 1-2 system rises stability

Sandvik Coromant has updated its CoroCut 1-2 system for rigid and rapid parting and grooving to feature spring clamp technology. This not only provides increased stability but eliminates the operator judgement required when using a torque wrench on conventional screw clamps.

As well as high security, the new CoroCut 1-2 design focuses on easy handling. The new patented clamping solution has a railed insert seat and a quick-release key that eradicates the need for a torque wrench. According to the company, this not only guarantees good stability and correct clamping force time after time, but also a smooth insert change. As a result, CoroCut 1-2 now ensures truly secure and efficient parting and grooving for all applications less than or equal to 38mm diameter.

Strong tool material (fatigue resistant alloy), high rigidity and effective chip control also offer the potential to increase feed rates when using CoroCut 1-2. In fact, longitudinal turning operation tests confirm that the new spring clamp allows for a feed rate increase of up to 27 per cent with maintained deflection. This, the company says, is because deflection is 2.7 times less with a spring clamp in comparison with a screw clamp.

In support of its new design features, CoroCut 1-2 offers over- and under-coolant on all tools. The under-coolant controls temperature at the cutting edge, resulting in less tool wear and more stable performance, while the over-coolant is deployed to evacuate chips. What’s more, these beneficial effects are witnessed at both high and low pressures.

An additional advantage is that connecting the coolant is facilitated by easy-to-use plug-and-play adapters. Traditionally, connecting coolant to a tool has been time consuming due to poor access and hoses getting in the way of the tool and the component. Adapters with plug-and-play functionality eliminate the need for a hose, providing a trouble-free coolant connection and tool change. Suitable for all material types, the CoroCut 1-2 system includes more than 700 standard inserts.
