Kyocera has introduced its MECHT range of indexable milling cutters. Due to its tool geometry, MECHT is suited to applications in shoulder face milling, plunge cutting and slot milling, as well as ramping. Like the entire MEC series from Kyocera, MECHT offers a positive and very light-cutting action, which achieves 90° shoulders and smooth surfaces.
Compared with conventional milling cutters in this category, the Kyocera product is characterised by a new combination of insert sizes. The larger bottom inserts are positioned at the first stage of the tool holder to handle higher cutting forces. This configuration stabilises titanium alloy machining and improves fracture resistance. At the same time, the design ensures higher reliability, as the bottom inserts are held in place by double-faced contacts. Another advantage is that the new flute design prevents chips from clogging.
The chip breakers require a significantly lower cutting force than other cutters, says the company. Due to this extremely sharp cutting performance, heat development at the cutting edge is kept to a minimum, which again ensures long tool life. Furthermore, MECHT was developed with heat-resistant MegaCoat Nano coating technology. The tough PVD-coating (PR1535) increases the breaking strength of the product, as well as the stable and long-lasting application possibilities.

As a part of the national effort to provide much needed PPE in the fight against COVID-19, Ricardo has turned to the production of face shields that will be used by frontline NHS healthcare staff, as well as key workers in the care sector.
To ensure that these essential PPE items can get to NHS employees who need them as quickly as possible, facilities at Ricardo’s Technical Centres in Shoreham and Leamington Spa are being repurposed as assembly lines and logistics centres for face shields. Ricardo used its manufacturing supply chain expertise to engage with an injection moulding partner, to create a tool capable of high-volume manufacture.

A high-precision, quick-change tooling system has been launched by Dormer Pramet for a variety of internal and external turning applications. Suitable for use on multi-tasking machines, the polygon shank coupling (PSC) is a spindle interface which promotes higher productivity through reduced set-up time and faster, more precise machining, reports the company.
Dormer Pramet’s PSC achieves this performance by deploying a tapered polygon cone shank and flange surface, which supports a high degree of rigidity. With accuracy in X, Y and Z of ±2 µm, PSC holders provide a high level of repeatability. In addition, a reduced overhang length minimises vibration and runout inaccuracy for a high-quality surface finish, making it suitable for both aerospace and general machining applications.
Connected by a triangular conical structure and cross section, which uses 1/20 taper, the PSC features internal coolant channels and a steel tool holder. More than 130 items are available, including a variety of tool-holder styles, internal tools, interface types and shank sizes.

Rockwood Composites and Leonardo have marked the 10th anniversary of their partnership with delivery of the 10,000th blade for the towed decoy on the Eurofighter Typhoon.
All parts are fully CNC machined and supplied paint-ready on a just-in-time basis. Rockwood has also supplied Leonardo with connector plates for the wing. Holly Jones, senior subcontract buyer at Leonardo in the UK, says: “Our 10-year partnership with Rockwood is testament to their ability to deliver quality composite components, consistently, when we need them.”

The 108 and 114 Mini tooling systems from Horn have been extended through the addition of new inserts with GM threading geometry that is suitable for turning ISO metric internal threads. Availability in the UK and Ireland is through the German manufacturer’s UK subsidiary, Horn Cutting Tools.
Horn’s chip-breaking geometry generates short lengths of swarf, even when processing what are normally long-chipping materials and those that are difficult to machine. The swarf is easier to handle, the risk of chip build-up is reduced and ‘bird nesting’ around the tool and component is avoided, reducing lathe stoppage time and increasing productivity.
Using the 108 system, users can produce metric internal threads from M10 with pitches of 0.5 to 1.25 mm, while the 114 system is suitable for pitches up to 2.5 mm. The inserts are available in partial and full profile design. Standard, low-vibration, carbide turning tool holders from the Mini system may be used, enabling the production of high surface finishes, even on deep threads, and ensuring high process reliability.
Mini-type inserts screwed on to the face of the holder are among Horn’s core products for turning and milling applications. The tools are especially suited to internal profiling and internal grooving. Furthermore, the Mini system range offers inserts with different geometries, substrates and CBN or diamond coatings in a variety of sizes for various internal diameters.
