Mabey and Acrow join forces

Mabey Holdings Ltd has concluded the sale of Mabey Bridge Ltd’s modular bridging business to Acrow Bridge, an international bridge engineering and supply company.

The sale’s structure includes all employees in the modular bridge team and the manufacturing site in Lydney, Gloucestershire. Both companies will continue to operate under their own brands. Mabey Bridge and Acrow Bridge have shared a similar mission, to accelerate construction through pre-engineered modular bridging solutions that help develop, improve and repair essential infrastructure in urban and rural areas. Financial terms are not being disclosed.

Silcoms installs Hermle five-axis machine

Bolton-based Silcoms supplies the aerospace industry with nickel alloy, titanium, stainless steel and aluminium engine ring components and assemblies, including seals, shrouds, segments and casings.

The company was awarded an additional contract in 2018 to supply a complex rotating fan seal for a large civil aircraft engine programme, which prompted the need for additional capacity. Managing director Jim Hill took the opportunity to develop a new process route that would speed production of the rotational titanium parts, while maintaining the tight tolerances needed.
The new method of manufacture now hinges on the use of a Hermle C50 UMT five-axis machining centre fitted with a torque table for carrying out in-cycle turning operations. Supplied by Kingsbury, the machine performs three operations in two set-ups that previously required five operations on three different machines. As a result, floor-to-floor time has been reduced, while fewer set-ups mean that the risk of accumulative tolerance error is minimal.
Produced from a titanium forging, the 1015 mm diameter fan seal has to be turned to a final wall thickness of 3 mm. Here, it is crucial to control dimensional accuracy and avoid distortion. After a number of preparatory machining stages, the Hermle five-axis machining centre completes the next five operations in two set-ups over 20 hours. Semi-finish and finish turning have been compressed into one operation on each side. During the second clamping on the Hermle, turned and milled features are completed. Critical dimensional features are held to ±20 µm over the full diameter of the part.
Says Hill: “Consolidating turning and milling on one machine has significant benefits. Apart from a reduction in component handling and an improvement in accuracy, it cuts the lead-time for converting a titanium forging into a finished seal, and reduces the total number of tools we need.”

IPS facilitates Industry 4.0 solutions

To avoid the possibility of engineers glazing over at the mention of Industry 4.0, “there is no better way to describe the potential rewards of the concept than by illustrating that better profitability and improved growth can only be achieved with customised digital manufacturing solutions”, says Starrag CEO Dr Christian Walti.

“And with Starrag’s Integrated Production System [IPS], users have available a modular solution that can be aligned with specific requirements, allowing individuals to effectively select their own à la carte solutions to realise the benefits of Industry 4.0 through automating and digitising their production.”
At the heart of IPS is a cell controller, proprietary to Starrag, which monitors machines and can guide and control the entire production process – in conjunction with a higher-level ERP system where applicable. The cell controller also ensures digital transparency by visualising system status, for example.
Developed in-house by Starrag, the cell controller is an open system that can link different system components, making it a very practical and cost-effective tool for customer-orientated Industry 4.0 solutions.
“IPS enables users to control and monitor their Starrag machines – standalone units through to flexible manufacturing systems and complete production lines – to ensure reliable production,” says Walti. “In addition, the technology enables us to support them in the complex task of using data in a networked production world to obtain added value.”
He adds: “Starrag has been using IPS components to develop wide-ranging Industry 4.0 solutions for a number of customers, including one company that invested in a flexible manufacturing system of six Ecospeed F2060 machining centres served by a rail-guided pallet shuttle system.”

New plant

KraussMaffei Berstorff is planning for the future and will build a new plant for extrusion technology.

At the beginning of June 2019, the company signed a rental contract with VGP, a project developer for commercial real estate, thus firing the starting shot for the approximately 55,000 sq m production hall and office complex. Work for the plant in the Laatzen/Rethen Ost business park should be completed by the end of 2022. The new location will have a technical centre, production and office facilities, and provide space for up to 750 employees.

£200,000 automated machining investment

Arrowsmith Engineering of Coventry is capitalising on 20% growth over the past 12 months by investing over £200,000 in a Doosan four-axis machining centre and robotic cell. It is hope the move will boost production speed and increase capacity by 50%.

The company is using lights-out manufacturing to run a precision aero-engine part 24 hours a day, seven days a week, supplying more than 200 components every month to customers based in Spain and the US. Integrating robots into the process has removed the need for a second machining centre.
Managing director Jason Aldridge says: “I’m a big fan of automation and don’t’ sign up to the notion that it’s taking jobs; if anything it will make us more competitive so we can take on additional people. The Doosan CNC machining centre and collaborative robot system is our first investment in robotics, and has been configured to suit our specific requirements for 24-hour manufacturing on a complex component for the aerospace sector. It has removed the need for an operator to load and unload the parts, and this person has gone on to a different production process that is more skilled. This is just the start of what we are sure will be a continuous investment drive in robots.
“It’s made us 15% quicker and given us a 50% capacity boost; that’s some payback already,” he continues. “Automation shouldn’t be seen as something that only the big boys do; SMEs can access it cost-effectively and we need to ‘grasp the nettle’ in order to bring the UK’s productivity in line with our international competitors.”
