Rolls-Royce Submarines to create jobs and expand

Rolls-Royce plans to almost double the size of its Raynesway site, creating hundreds of new jobs in Derby. Funded by the MoD, the site development is required to meet growth in demand from the Royal Navy and as a result of the recent AUKUS announcement.In March 2023 confirmation arrived that Rolls-Royce Submarines would supply all the nuclear reactor plants that will power new attack submarines as part of the tri-lateral agreement between Australia, the UK and US.This increase in demand will see new facilities built on recently acquired land surrounding the existing Raynesway site. It will also create 1170 skilled roles.

Vollmer VDays focus on efficient processes

Sharpening specialist Voller recently opened its doors for the company’sVDays 2023 in-house trade fair at Biberach. Across three days, customers, suppliers and partners had the opportunity to immerse themselves in the world of grinding, eroding and laser machines with keynote speeches, specialist talks and product demonstrations. Around 400 visitors from around the world attended the event, which not only focussed on automation and digitalisation, but also efficient production using sustainable processes.

“We’re very satisfied with the popularity of and interest in our VDays,” says Jürgen Hauger, joint CEO of theVollmer Group. “In particular, we enjoyed the face-to-face conversations that we were able to have with our customers and partners.”

Over the course of VDays, Vollmer product managers and engineers explained sharpening technologies for various grinding, erosion and laser machines, as well as their potential applications in the metalworking industries. These presentations also included the latest innovations in tool manufacturing, such as the VLaser 370 laser machine, VGrind series tool grinding machines and the VHybrid 260 grinding and erosion machine.

Other machines, such as the CS 860 and the CSF 860 grinding machines, are suitable for the sustainable sharpening of circular saws. These models can machine the tooth face, tooth top and flanks of carbide-tipped circular saw teeth with high precision, energy efficiency and automation.

“Together with partner companies at the VDays, we managed to map the entire process chain in tool manufacturing and indicate how important digitalisation, automation and process efficiency are to tool grinding,” explains Dr Stefan Brand, joint CEO of theVollmer Group. “These trends offer opportunities for differentiation and competitive advantages, both for our customers and for ourselves.”

Apprentices meet Emma Wiggs Challenge

Design concepts to help people with disabilities, developed by apprentices at engineering training centre Oxfordshire Advanced Skills, were revealed at the final of the Emma Wiggs Challenge. Double Paralympic champion Emma Wiggs MBE, who launched the competition earlier this year, was one of the judges who assessed the entries, which aimed to show how design engineering can be used to improve life for people with disabilities.

The winning entry was a low-level pull cord assistance device (LLPCAD) designed by Owen Mayers, to tackle the critical safety issue of unreliable and inaccessible emergency pull cords in disabled toilets. Owen’s solution is a cost-effective device, designed for easy installation or retrofitting in most locations. The highly commended finalist was the Scooter Buddy, a cost-effective, portable product that is suitable for storagein a chair bag or rucksack, designed by the team of Ryan Budd, Matt Chambers and Ben Hibberd.

Selecting the best copper for EDM electrodes

When it comes to EDM electrodes, having the best copper is essential for optimal performance, reports EDM Plus, a UK specialist in EDM machine sales, EDM consumables sales, EDM subcontracting and other related services. The company says that copper is an essential part of the process, as it provides the electrical current needed to create the spark that powers the machining process. The right copper for EDM electrodes will ensure consistent and successful machining.

Several types of copper are available for EDM electrodes, including oxygen-free high-conductivity (OHFC) copper, electro-refined (ER) copper and electrolytic tough pitch (ETP) copper.

For EDM electrodes, OHFC is the preferred choice because it offers excellent electrical conductivity, low resistivity and good thermal stability. It also has higher resistance to corrosion than other types of copper and is suitable for use in harsh environments.

When selecting EDM electrodes, EDM Plus says machine shops should look for those made with a high-grade OHFC copper alloy. This type of alloy offers enhanced wear resistance and is suitable for use in a wide variety of applications. Additionally, it has a relatively low coefficient of friction and can withstand higher temperatures for longer periods of time than other types of copper.

For added protection against wear and tear, consider using EDM electrodes made from an alloy containing additional elements like chromium or molybdenum. These alloys are more resistant to corrosion and are more suitable for use in corrosive environments. They also tend to offer improved properties when exposed to high temperatures or pressure.

Finally, keep in mind that the cost of EDM electrodes varies depending on the type of copper used. OHFC is generally more expensive than other types of copper, but its superior performance makes it worth the investment.

Implant manufacturer opts for Makino wire EDM

A new U6 HEAT from Makino has replaced two outdated wire-cut EDM machines at orthopaedic implant and associated surgical instrument manufacturer MatOrtho. The new wire-erosion machine arrived at MatOrtho’s manufacturing facility in Leatherhead towards the end of March 2023, with installation performed by NCMT, the sole UK sales and service agent for Makino.

David Shand, operations director at MatOrtho, says: “The new Makino wire EDM will significantly increase our instrument production capacity compared with the two machines it replaces. Greater accuracy and speed will allow us to meet our R&D needs and support future sales. This latest significant investment comes at an important time in our transformation as we expand to meet the growing demand from our worldwide customer base.”

Selection of the Makino was due to the quality of both the machine’s build and the service received during the sales process, right through to training at NCMT’s Technical Centre in Coventry. Another important aspect was the environmentally friendly operation of the U6 HEAT, which has low running costs, particularly in respect of reduced wire consumption. Shand adds that it will help drive the company’s transition towards a net-zero carbon footprint, especially as only one EDM machine is now drawing power rather than two.

NCMT’s Jon Marshall, Makino EDM sales manager UK south, says: “The Makino U6 HEAT is geared towards high-performance production which, together with the machine’s inherent precision, makes it a perfect fit for MatOrtho’s requirements for both production and research.It’s been a pleasure dealing with Paul Clancy, the company’sproduction engineering manager, and the whole team throughout the process and we at NCMT look forward to assisting MatOrtho with its future investments.”
