Brings scalable automation to turning operations

By making cutting forces, vibration, chatter and incut status visible as they occur, the solution helps teams stabilise performance, enhance part quality and consistency and reduce waste.

CoroTurn Plus combines sensorised tooling with two levels of digital capability. Used with CoroPlus® Viewer, it provides real time, passive insight to support operator decisions. Used with CoroPlus Connected, the same signals enable active, machine integrated protective actions within defined limits – helping users clearly distinguish between visualisation and automated response.

CoroTurn Plus streams live data from the cut to CoroPlus Viewer on a PC or tablet, enabling faster, data‑driven decisions and traceable continuous improvement. Live visualisation and reference processes support precise intervention when trends move outside defined limits. Operators receive over‑limit audible alerts, can hover to inspect values, and can review and flag deviations to accelerate root‑cause analysis. As tool‑condition signals accumulate, teams identify when an insert is approaching end‑of‑life and replace it at the right moment, extending tool life and avoiding unplanned downtime.

For machine‑integrated control, CoroTurn Plus connects to CoroPlus Connected, fully integrated with the machine’s NC. Users set limits on chatter, load and vibration in software or via NC code; if an unexpected event occurs, the control automatically initiates protective interrupt actions to safeguard components, tools and equipment. These actions are configurable by the end user. 

Feed‑rate and cutting‑speed override configurators enable in-process optimisation, while data tracked to component position strengthens diagnostics and continuous improvement. This autonomy lets the machine handle more routine decisions within configured boundaries, increasing effective operating hours, especially during unmanned evening or night shifts and reducing downtime across the day.

Industrialised features include automatic connect and disconnect from the bar, ready‑to‑machine system checks, start and stop of data recording and system‑unavailable messaging. By storing and documenting cutting data for each run, teams compare batch performance, red‑flag material deviations early and maintain end‑customer documentation and certificates for full traceability. Together, sensorised tooling, visual analytics and NC‑level integration turn raw signals into enforced limits and actions, making production steadier, safer and more consistent with fewer interventions.

“With CoroTurn Plus we visualise hidden behavior in the cut into clear signals, so teams can recognise material variation, tool wear and process instability as they happen,” said Åke Åxner, global project manager – machine integration at Sandvik Coromant. “In combination with CoroPlus Connected, the control makes protective decisions, stopping, retracting and resuming within defined limits, which reduces unplanned downtime and increases overall machine utilisation.”

“Sensorised tooling is the most practical bridge into more advanced automation because it turns raw signals into safe, machine‑enforced actions,” added Leland Bailey, Project Manager at Sandvik Coromant. “By capturing high‑resolution cut data and connecting it directly to the control, teams enable unmanned windows, reduce downtime, pinpoint insert end‑of‑life and institutionalise best practice, while clear, actionable visuals help operators at every experience level make safe, confident decisions.”

For the manufacture of high value components such as discs, casings, shafts, pumps and valves, CoroTurn® Plus provides unparalleled real-time insight into what’s happening right inside the cut.
