Sandvik Coromant has launched CoroTurn Plus, a sensor-equipped turning adaptor designed to provide real-time process visibility, improve machining stability and support higher levels of automation in turning applications.

The new system enables manufacturers to monitor cutting forces, vibration, chatter and in-cut status in real time, helping operators identify process instability, material variation and tool wear before they impact productivity or component quality. By making machining conditions visible during the cut, CoroTurn Plus is intended to improve process security, reduce waste and support more consistent production.

CoroTurn Plus combines sensor-integrated tooling with two levels of digital capability. When used with CoroPlus Viewer, the system provides live visualisation of machining data via a PC or tablet, allowing operators to track performance trends, receive audible alerts when limits are exceeded and review deviations for faster root-cause analysis. The platform also enables teams to identify insert wear trends more accurately, helping optimise tool life while avoiding unplanned downtime.

For higher levels of automation, CoroTurn Plus integrates with CoroPlus Connected and the machine’s NC control system. Users can define vibration, chatter and load limits directly in the software or NC code. If those limits are exceeded, the machine can automatically trigger protective actions such as stopping, retracting or resuming the process to protect tooling, components and equipment.

According to Åke Åxner, global project manager for machine integration, the technology transforms hidden cutting behaviour into clear process signals, enabling manufacturers to detect instability and react immediately. Product manager Leland Bailey adds that sensor-based tooling provides a practical route towards more advanced automation by converting machining data into safe, machine-controlled actions.

By combining live process monitoring with machine-level integration, CoroTurn Plus aims to support unmanned machining, improve machine utilisation and deliver greater consistency across turning operations.

As pressure on global raw material supply chains continues to intensify, manufacturers are increasingly reassessing how cutting tool materials are used throughout the machining process. According to Tungaloy Corporation, carbide remains essential for heavy roughing applications, but its use is not always technically necessary in finishing operations where cutting loads are significantly lower.

In many finishing applications, the focus shifts away from maximum toughness towards process stability, surface quality and efficient material usage. Under these conditions, cermet provides a practical and engineered alternative capable of reducing carbide consumption without compromising machining performance.

Finishing operations typically involve shallow depths of cut, high cutting speeds and continuous or lightly interrupted machining conditions. These are precisely the environments where cermet performs most effectively. Developed from ceramic and metallic components, cermet grades are specifically engineered to deliver high wear resistance, predictable tool life and excellent surface finish in stable machining conditions.

Tungaloy’s cermet range is designed for finishing and light semi-finishing applications in steels and alloy steels. The NS9530 grade provides a balanced combination of wear resistance and toughness for stable finishing operations, while GT9530 is optimised for precision finishing applications where surface quality is critical. The AT9530 grade has been developed specifically for alloy steels, delivering consistent machining performance in continuous cutting conditions.

Rather than attempting to replace carbide universally, Tungaloy emphasises that cermet should be viewed as part of a smarter material allocation strategy. When matched correctly to the application, cermet can help manufacturers reduce dependence on carbide resources, maintain stable productivity and improve overall process efficiency.

High-feed milling places enormous demands on cutting tools. Feed rates, chip evacuation, surface finish and tool life all directly influence machining productivity, making insert design critical to overall performance. With the launch of its new CHASEFEED SRMT insert line, TaeguTec has introduced a solution engineered to overcome the common limitations associated with conventional high-feed milling inserts.

A key advantage of the new SRMT design is its ability to utilise all four cutting edges fully and equally. In many competing insert designs, adjacent cutting edges become exposed to the cutting zone during machining, leading to premature wear and inconsistent performance. TaeguTec’s optimised insert geometry eliminates this issue by keeping neighbouring edges clear of the cut, allowing each corner to deliver reliable tool life and stable machining performance in succession.

Chip control is another major challenge in high-feed milling operations. Poor chip evacuation can result in chips re-entering the cutting zone, damaging workpiece surfaces, causing insert chipping and even jamming the cutter. The SRMT insert addresses this issue with a geometry designed to direct chips efficiently into the gullet and away from the workpiece. This capability improves surface finish and enables the insert to perform effectively across roughing, semi-finishing and finishing applications.

Sharp cutting edges further enhance performance by reducing cutting forces and improving machining efficiency in difficult materials. Higher feed rates can therefore be maintained without compromising tool life or component quality, reports TaeguTec.

The SRMT range is available in 07, 10 and 14 insert sizes, supported by four dedicated chip former geometries covering steel, stainless steel, cast iron, titanium, superalloys and hard materials.
