Like a number of socially responsible and conscious manufacturers, Yorkshire Precision Engineering Ltd (YPEL) was among those that offered to support the Government and its Ventilator Challenge UK consortium.

When the call came from Rolls-Royce plc, YPEL turned the first batch of parts around in just one week.

Founded in 2001 by Michael and Lynda Laybourne, the Keighley company received the call for 8000 turned brass parts at the end of March. Within a week of getting the go-ahead, YPEL had programmed the parts, sourced the materials, identified the tooling, and had the parts machined, inspected, certified and out the door.

The rapid turnaround of high-quality turned components led to a second enquiry from the Ventilator Challenge consortium, a requirement for prismatic parts; and this is where a Bridgeport Hardinge V1000H from the Engineering Technology Group (ETG) stepped up to the mark.

Primarily functioning as a turned-parts business, YPEL has operated a solitary machining centre, an ageing Hardinge VMC600II workhorse, alongside its fleet of turning centres for several years. When the company required additional milling capacity, YPEL once again turned to ETG and its Bridgeport Hardinge range of VMCs, investing in a four-axis Bridgeport Hardinge V1000H machine that proved integral throughout the Ventilator Challenge.

With 4000 complex prismatic components to machine, YPEL created a workflow whereby the plastic housing parts were initially machined on the Bridgeport Hardinge V1000H prior to a second operation on a turning centre and a final operation on a Hardinge VMC600II.

Sales and financial director Lynda Laybourne says: “The capabilities, precision and flexibility of the Bridgeport Hardinge V1000H via its integrated 4th axis meant that that it did the bulk of the work. Our new V1000H conducted face and side milling, pocketing, grooving, drilling and threading in a 20-minute cycle.”

Part of the British Engines Group based in the north of England, BEL Engineering operates two factories at Newcastle-upon-Tyne and Cramlington to provide project-managed manufacturing solutions, some of which involve the heavy-duty subcontract machining of large workpieces weighing up to 40 tonnes.

Much of the metal-cutting activity involves turning on horizontal- and vertical-spindle lathes, but parts often have to be transferred to a prismatic machining platform for milled and drilled features. Around 30 three-axis CNC mills are available at BEL for this purpose. However, for such parts to be produced more economically in one clamping, the subcontractor recently invested in a Hermle C62 UMT five-axis, vertical-spindle machining centre supplied by Kingsbury.

Having a nominal 1 cubic metre working envelope, the machine was duly installed at the Newcastle factory. It was BEL Engineering’s second venture into this technology; an Italian-built, five-axis mill-turn centre with travels in excess of 2 m in X, Y and Z having been installed a few years earlier. There is also a pair of Japanese-built five-axis CNC milling centres on site, one with a 10-pallet storage system.

The Hermle fits neatly between these larger and smaller five-axis models, extending the subcontractor’s capacity. In particular, following the company’s accreditation in October 2019 to AS9100, the machine is proving to be of ideal size to produce aero-engine parts for a nearby customer.

Bel Engineering’s chief production engineer Phil Westgarth says: “We mainly process tough materials, from high-strength steels through titanium, to nickel superalloys like Hastelloy, Waspaloy and Inconel. So we need powerful, rigid machine tools. A pair of similar Hermle mill-turn centres is being used successfully at another of our group companies, Michell Bearings, so this influenced our choice of the German machine.”
