The machine is the most advanced of its kind in the world and sets new standards for high-end manufacturing in the UK. The machine, a StarragHeckert BTP5000, is able to produce titanium components over 3m long to tolerances that equate to a third the thickness of a human hair. The components are used in the manufacture of the F-35 Joint Strike Fighter – the rear section of which is built at BAE Systems Samlesbury before being shipped to Lockheed Martin in America. The precise tolerances delivered by the new machine ensure that the outer shape of the F-35 matches up to the exacting standards needed to make an aircraft that meets the required stealth performance capability demanded by Lockheed Martin. The machine is referred to as the Long Spar Longeron Machine, owing to the long spa and longeron sections is was built to machine. Featuring twin spindles the machine is capable of machining two parts at the same time meaning double the efficiency. At peak rate production aircraft sets will be produced at a rate of one a day. The initial concept for the machine was born out of a discussion between BAE Systems and StarragHeckert machine tools which looked at ways to deliver a more accurate and effective machining method for long titanium parts. The machine has now been extensively tested and recently produced two components at the same time to exactly the same standard. Frank Brinken, CEO of Starrag Group, said: “We knew we were entering unchartered territory when we began this project. Through a true team working approach built on trust we worked closely with BAE Systems to make it a success. Much hard work has been injected into the project from both companies since 2006 when the idea was born. The result is the most advanced titanium cutting machine of its kind in the world, delivered safely, on time and within budget.” The Long Spars and Longerons machine is the first of two machines to be installed in the machining facility. The second is planned to begin installation in 2014. www.baesystems.com
