The engine’s induction system features a twin-butterfly plenum chamber which allows cooled air to be fed directly into the engine, while also maintaining good aerodynamic flow to the rear wings. A significant percentage of the SR8’s complex and high-precision engine and car components are manufactured using Hardinge milling machines. They are manufactured from a range of materials – aluminium, alloys, steels etc. – and are machined to high accuracy and equally high surface finish. The parts often exhibit complex profiles and forms and feature intricate detail – thin walls, deep bores – and are required (and manufactured) in low-to medium volumes. To cope with these manufacturing requirements Radical relies on Hardinge milling machines and, in the very near future, Hardinge turning technology too. (FEA) - a proven, highly-technical procedure that ensures a stiff, structurally-sound machine tool design. The 4,894lb/2220-kg machine base is constructed from high-quality cast iron that contributes to overall stability and rigidity. Says David Andrew, Sales & Marketing Director at Hardinge, UK. “The Radical SR8 racing car looks fantastic and it’s great to know that our machine tools have been instrumental in building such a world-beater. Hardinge Motorsport is sponsoring the SR8 factory car in the forthcoming Dunlop Radical Enduro Championships – and we have high hopes that our drivers – Nigel Greensall and Helen Ray – will race away with it. We have a long-established relationship with Radical and we are delighted that they have continued their investment in our machine tool technologies with the new Talent machine.” Talent 10/78 TURNING CENTER The Hardinge Talent 10/78 turning center installed at Radical’s production facility in March 2007 is a compact and rigidly constructed machine. It is equipped with a 25hp/18.5kW spindle drive (with Fanuc control) and includes a 3-jaw power chuck as standard. The machine also has an A2-8 (3,500rpm) spindle with 3.07” (78mm) through draw tube capacity. Rotation time for the Talent’s bi-directional 12-station VDI-40 turret is .78 seconds (unclamp/index/clamp) to an adjacent station. The non-rising turret index is achieved using a separate brushless servomotor and the turret positively locks into position using a 3-piece curvic coupling. Through-tool coolant and headwall coolant capability are standard and can accommodate water- or oil-base coolant. Heavy-duty, ball-type linear guideways are used for X- and Z-axis movements, providing added stiffness, damping, and increased surface contact area. This results in a very stiff, durable and reliable machine. Rapid traverse rates for the X and Z axes are an impressive 1181ipm(30 m/min) and maximum X-axis travel is 10.7”(271mm) and maximum Z-axis travel is 23.62”. The turning center has a ribbed 30-degree slant bed base that provides superior rigidity and durability. All structural components and castings are qualified by Finite Element Analysis For more information +44(0)1733 331616, fax +44(0)1733 264959 info@radicalsportscars.com www.radicalextremesportscars.com S.P & P Magazine . . 27 http://www.radicalextremesportscars.com
