Guhring SC-TM-Z SP Completes Thread In Just Two Turns

Guhring has expanded its thread-milling range with the introduction of the SC-TM-Z SP high-performance full-profile thread milling cutter. Designed to create a complete thread in just two revolutions, the new tool reduces cycle times while adding to one of the industry’s most comprehensive thread-milling portfolios.

According to Guhring UK national sales manager Chris Bush, the company now offers solutions ranging from micro and single-pitch thread mills to combination drill, chamfer and thread mills, providing manufacturers with options for virtually every threading application.

The SC-TM-Z SP is available in metric and metric fine sizes from M3 to M20. Its staggered-tooth, staggered-pitch design, combined with a patent-pending flute geometry, minimises radial forces and vibration, eliminating the need for a spring pass. The result is higher cutting speeds, improved dimensional accuracy and a more reliable machining process.

In performance trials, the cutter machined an M10 thread to 2.5xD in ST52 carbon steel 55% faster than a competing tool, while extending tool life by 17%, from 700 to 820 components. Guhring attributes this performance to the combination of its premium carbide substrate, Sirius coating and advanced cutting geometry.

Suitable for steels, stainless steels, cast irons, non-ferrous materials and heat-resistant alloys, the SC-TM-Z SP maintains true-to-gauge performance to thread depths of up to 2.5xD, delaying tool radius correction and extending process stability.

To support users, Guhring provides free access to its CNC Guhro ThreadMill programming generator, which produces programs for Siemens, Heidenhain, FANUC, Mazatrol and Hurco controls. The company also offers on-site technical support through a team of 20 field engineers across the UK and Ireland. More information www.guhring.co.uk

Ceratizit heralds MACH 2026 as its best of all time

Ceratizit UK & Ireland has reported its most successful MACH exhibition to date. The company’s stand attracted strong interest throughout the week, with manufacturers visiting to explore the company’s latest cutting tool, tooling management and work-holding technologies.

The exhibition showcased Ceratizit’s machining portfolio across milling, turning, drilling, threading, grooving and parting applications, supported by demonstrations from the company’s UK Technical Centre. Among the standout attractions was the CTC5240 titanium indexable milling system display, developed in collaboration with the University of Sheffield AMRC, Heller Machine Tools and Siemens NX.

Designed specifically for difficult-to-machine materials including titanium, Inconel, Hastelloy and Waspaloy, the CTC5240 grade generated significant attention from engineers attending the exhibition. Ceratizit demonstrated how its proprietary coating technology improves heat resistance, chip formation and tool life in demanding titanium machining operations.

A key highlight was a live machining demonstration using the new RADX porcupine cutter paired with SXHU 120408ER-F41 CTC5240 inserts during a full-slot milling operation in TiAl6V4 titanium alloy. The application achieved a material removal rate of 318.78 cm³/min while benefiting from eight usable cutting edges per insert, creating a highly competitive solution for heavy-duty titanium roughing applications.

The Ceratizit UK & Ireland engineering team is currently working with manufacturers to implement productivity and cost-saving improvements identified during MACH.

The company also continued its long-running MACH charity initiative, with visitors entered into a prize draw to win a Hope HB160 mountain bike in exchange for donations to the British Heart Foundation and Cancer Research UK. Over the past 16 years, the initiative has raised more than £100,000 for the two charities.

Live turning insight for safer, smarter automation

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.
