$20m three-year defence contract

Meggitt PLC has received a three-year continuation contract with Northrop Grumman Corp for the supply of fuel bladders on the F/A-18 Super Hornet.

The contract is valued at around $20m and deliveries are scheduled to commence this month. Using innovative polyurethane technology, Meggitt’s fuel bladders offer a long-life, lightweight solution that is highly flexible, durable and maintenance-free.
Chris Allen, president of Meggitt’s airframe division, says: “The F/A-18 Super Hornet is the tactical aircraft of choice for the US Navy. We’re very proud that our innovative fuel cell technology has been selected to support this next-generation fighter, protecting both pilots and aircraft in mission-critical situations around the world.”

AM expert

The GTMA has appointed an academic advisor to support activities in additive manufacturing.

Dr Jennifer Johns will bring a range of expertise to the association, including research on technological change and innovation in global supply chain networks. A reader in international business at The University of Bristol, Johns recently published an extensive report examining the impact of additive manufacturing on supply chains in the UK, Germany and US.

Digital-ready fine-boring system

Kennametal has introduced a new line of digital-ready fine boring tools that is said to make precision adjustment easy, enabling more productive, predictable and accurate boring.

The eBore fine-boring system consists of cutting units to cover a diameter range from 6 to 1020 mm, and an optional digital display that makes precision adjustments as simple as turning a screw.
“For many workpieces, the boring operation is often the final step, and a simple mistake can lead to scrapped parts,” says global product manager Marcus Paul. “The eBore does away with the traditional ´count the graduations´ approach to boring and reduces costly mistakes. We’ve found there is tremendous operator acceptance due to its simplicity and ease-of-use. And because the same eBore digital device can be used across multiple types of tools and on various machines, it’s easy on the budget.”
Offering no-mistake adjustments and accuracy to within 2 µm, Kennametal´s eBore digital device is an optional – though extremely useful – part of the Kennametal digital boring system. The chip and coolant-resistant device contains a glass scale that keeps track of boring-bar movement. Simply snap it in place, turn the boring head’s adjustment screw by the desired amount, and the tool is ready for the next boring operation.
Ultimately, with eBore, there is no need to remove the boring head from the spindle for adjustment, nor to count graduations or take notes. Concerns over backlash and movement due to overtightening of the boring head’s locking screw are a thing of the past, as are endless test cuts and ‘sneaking up on the bore’. The result is less scrap, less downtime and faster set ups. The device shuts off automatically after 30 seconds and provides more than 5000 adjustments between battery changes.

£30m nuclear sector contract for TSP

Workington-based TSP Engineering has been awarded a £30m contract to manufacture nuclear waste containers for Sellafield Ltd.

The 50-tonne, lead-lined containers will transfer nuclear waste from the legacy Magnox Swarf Storage Silo to newly built storage facilities on the site. This new work is expected to create or sustain approximately 200 jobs at TSP Engineering. Alongside other orders placed with the business, the work will bring the TSP Engineering workforce to more than 250 people.
Martin Chown, CEO of Sellafield Ltd, says: “TSP’s success in winning this contract proves our nuclear supply chain can compete with the best in the world.”

Milling cutters for tool and mould making

Mapal has introduced a completely new line of solid-carbide end mills – the OptiMill-3D series – which has been specially developed for the tool and mould-making industry. Along with extremely heat-resistant coatings and special carbide substrates, the new cutting tools are characterised by dimensions and geometries specifically adapted to mould making.

Suitable for milling hard parts in the domain of 45 to 66 HRc, the OptiMill-3D-HF-Hardened is offered with four or six cutting edges. Mapal has developed the two variants for high-feed milling on particularly challenging materials. In addition, to optimise performance and longevity on challenging tasks like interrupted cutting, the company has developed special face geometry.
The four-flute tool is the primary choice for roughing and pre-finishing. Available from 2 to 16 mm diameter, the four-flute tool is suitable for long overhang applications such as machining in deep cavities.
Also designed for roughing and pre-finishing, the six-flute series is said to demonstrate impressive characteristics when finishing flat surfaces with a high feed rate. Moreover, with a PVD coating, the tool dissipates heat generation to ensure tool life is prolonged. Available from 6 to 16 mm diameter, the OptiMill-3D-HF-Hardened is complemented by the three and four-flute OptiMill-3D-HF for softer material machining.
Also new to the solid carbide range is the new OptiMill-3D-CR-Hardened with a corner radius. Suitable for finishing 3D mould tools up to a hardness of 66 HRc, this line produces smooth, high-gloss surface finishes when machining at maximum feed rates. Offered in diameters from 4 to 12 mm with accurate corner radii of 0.5, 1 and 2 mm, the PVD coated OptiMill-3D-CR-Hardened is available with a selection of different lengths to suit the machining demands of users.
