A specialist in electromagnetic wave filters for the defence sector has increased its machining capacity with the installation of new Quaser technology. BSC Filters, which designs and manufactures microwave filters, diplexers, waveguides and coaxial passive components, has reacted to a changing need for more complicated product types by installing the latest vertical machining centre.

Working with the Engineering Technology Group (ETG), the York-based company commissioned the machine for its efficiency, compact floor space, rigidity and accuracy, with its 12,000 rpm spindle improving production speed considerably. The Quaser also comes with 30 tools, the latest swarf management technology and Heidenhain controls.
Daniel Malarkey, machine shop supervisor at BSC Filters, says: “Over the past 12 months, our business has grown 22% and this is largely due to demand for more complex components from the defence sector. We had to meet this demand head-on, which is why we chose to engage with ETG to help us specify a new machine that would give us flexibility, speed and consistent quality.”
He continues: “The ETG service was excellent and the capabilities of the Quaser MV134EH were quickly identified and agreed. In addition, the machine was installed within the timeframe requested. We now have the additional capacity required to meet the 22% growth and, importantly, go after more new business opportunities.”
Lee Adamson, regional sales manager at ETG, adds: “The Quaser is proving such a popular machine for subcontract manufacturers, and it’s not difficult to see why. The compact footprint means it can be easily installed on the shop floor, yet despite its size it offers outstanding performance, thanks in part to the high precision linear guideway used in three axes.”

Starrag’s NB 151 impeller and blisk machine made its UK public debut at the recent aerospace-focused ‘Inspiration through Innovation’ manufacturing best-practice event staged by Seco Tools. The new NB 151 could be seen performing the live machining of titanium and Inconel blisk segments as part of a comprehensive programme of best practice demonstrations and seminar presentations.

Starrag’s demonstration saw the twin-pallet NB 151 machining the segments in a single set-up, courtesy of specially-developed A and B rotary axes. The axes’ spindle movement allows the tool/cutting angle to be positioned relatively close to the workpiece, resulting in not only a more stable machining process, but a far more effective route to minimal cycle times.
Importantly, this improved accessibility to the workpiece is courtesy of a B-axis stroke of 280° which, together with the compact A axis and relatively slender spindle, enables the component to be accessed in all directions, even at the bottom of the Y-axis stroke.
As a result of the collaboration between Starrag, Open Mind and Seco, the demonstration highlighted an optimised machining solution that eliminates the traditional problems of short tool life and excessively long cycle times associated with difficult-to-machine materials such as titanium and Inconel.

MACH Machine Tools, part of the Vigilance Group, has recently introduced a range of CNC bed mills equipped with the advanced DynaPath control. There are three machines in the range: the MDM 700 (X, Y and Z-axis travels of 710, 400 and 500 mm respectively); the MDM 850 (830 x 500 x 610 mm); and the MDM 1000 (1000 x 500 x 610 mm).

In addition to the machines’ ISO40 taper spindles with up to 5000 rpm spindle speed, and 1524 x 330 mm working tables offering a maximum load capacity of 500 kg, all three models are equipped with a range of value-added features supplied as standard. These include a 12.1” touchscreen, MPG hand wheel, air draw bar, interlock table guard and coolant equipment. Furthermore, Wi-Fi capability facilitates ‘remote’ diagnostic and online support.
The DynaPath control system is inherently versatile and features conversational and ISO/G-code programming capability. An 8 Gb on-board (program) storage facility, combined with 1000-line look-ahead, ensures fast processing speeds and responsiveness.
Another feature of the control is its simple to understand menus, and the integration of on-screen graphics to help eliminate programming omissions and errors. The provision of an advanced DXF reader, as standard, featuring grouped hole and contour selection, adds to the control’s flexibility and appeal.
Datum setting using alignment, a suggested feeds and speeds database, sub-program calling, the ability to use macro-programming, the ability to facilitate program simulation using tool path or 3D rendered graphics, and programmable spindle control – are among further features of the DynaPath control.
“The first MDM machine – a MDM 1000 – arrived in the UK at the end of September and was sold immediately,” says Mike Corbett, MACH Machine Tools’ CNC machine tool divisional manager. “We’ve since brought in more machines, and interest in them has been nothing short of phenomenal.”

Founded in 2003 jointly by John Biddlecombe and Simon Kingdon-Butcher, Global Technologies Racing (GTR) is a specialist manufacturer of laminated carbon-fibre components for the UK motorsport sector, supplying most of the Formula One teams.
Over the past decade and a half, GTR has become so successful that the constantly rising demand on its machine shop in Easthampnett, West Sussex, meant it needed to expand into a second facility in nearby Bognor Regis at the beginning of 2018. Shortly after moving in, a pair of Hermle C400 machining centres was ordered from UK agent Kingsbury to boost the contract machinist’s capability for five-axis processing.

The first, with a coolant tank for ‘wet’ machining and an additional 50-pocket tool magazine to supplement the standard 38 cutters, was delivered in mid-2018. This machine was followed in February 2019 by a second model equipped with dust extraction for the ‘dry’ machining of composite materials without coolant. Both machines have a trunnion-mounted table that provides the fourth and fifth
CNC axes.
Kingdon-Butcher says: “Wherever possible we avoid the wet cutting of carbon fibre, but some of the components produced at our Fontwell factory have aluminium or titanium inserts within their structure, depending on the customer’s specifications. In those cases we have to cut in the presence of coolant to avoid the heat that would be generated if we were to machine metals without coolant. This ensures that the structural properties of the adjacent areas of composite are not affected.”
Tolerances down to ± 0.01 mm have to be held and, while this is commonplace when machining metals, on carbon fibre parts it is challenging. GTR’s success in this area is down to its long experience working with composites, coupled with the rigidity of the Hermle machines.

Major growth in the oil and gas sector has seen a Scottish manufacturing specialist tap into the expertise of the Engineering Technology Group (ETG). Tayside Precision Tools Dundee, which is an expert in manufacturing complex parts in small volumes, recently invested in a new Quaser MV184 that has immediately unlocked additional capacity.

“The components we are milling require a very precise finish and the Quaser gives us the ability to produce repeatable accuracy faster than ever before,” explains John Welsh, Joint owner of Tayside Precision. “We’ve already secured a contract in the oil and gas sector to go straight on the machine.”
Tayside’s Quaser MV184 is the largest investment the firm has ever made and is the first time ETG has worked with the company.
Welsh says: “ETG were great, from understanding our milling requirements and identifying the machine, to helping us spec it out in the agreed timescale. I was also very impressed with the training, which meant we could quickly get the most out of the machine.”
Ross Milne, regional sales manager (Scotland) at ETG adds: “The MV184 is a great addition for specialist subcontractors like Tayside Precision Tools Dundee, with the large table area providing superior flexibility for work in progress. The space allows for varied work holding, so you can set up different parts on the table at the same time, which helps reduce set-up times.”
