Giving Triumph the cutting edge

Article Type: News From: Assembly Automation, Volume 32, Issue 2

Cutting tool expert MAPAL is now supplying all of the critical tools for the latest engine line retooling project at Triumph Motorcycles. This follows more than a decade of close co-operation between the two companies, during which time MAPAL has helped Triumph to achieve continual improvements in its manufacturing operations.

Today, Triumph Motorcycles is a British manufacturing success story. It produces 50,000 motorcycles annually and employs around 1,600 people worldwide. But it was not always like this. In 1983, the Triumph Motorcycle brand seemed doomed. However, entrepreneur John Bloor bought the company’s intellectual property and the rights to the name and, under his ownership and guidance, a new range of bikes was launched in September 2009.

In the first year, the company sold 2,000 bikes, all produced in the UK. The machine tools used to manufacture critical components were, however, supplied from Japan complete with tooling. This arrangement was initially satisfactory but soon its growing success meant that Triumph was struggling to meet demand.

One particular bottleneck was the machining of the valve seats, and the company’s engineers asked MAPAL for proposals to address this problem. MAPAL produced a solution that reduced the number of tools needed from five to just two, leading to a dramatic reduction in cycle time.

Other production line bottlenecks soon emerged, however. To address these, MAPAL analysed the tooling requirements for the whole line and developed improvements that greatly increased throughput while reducing per-part production costs. Because of this success, Triumph invited MAPAL to tender for tooling on its next new production line, which was being set up to manufacture type 806 four-cylinder engines.

After participating in a competitive tendering process, MAPAL supplied around half of the tooling for the 806 engine line, but for the next new engine line, MAPAL delivered a turnkey project including all tooling. This was repeated on two more production lines for Triumph’s plants in Thailand.

With every new project, machining tolerances become tighter and cycle times shorter, but its wide experience in the automotive sector has allowed MAPAL to address these challenges. It has, for example, introduced Triumph to an innovative arrangement for valve guide and seat finishing, which uses two tools for machining the valve seat and the valve guide complete.

Most recently, MAPAL has been working with Triumph on an engine production line that is being completely retooled at the Hinckley plant. As always, Triumph put this work out to competitive tender, but concluded that MAPAL offered the best balance of cost, quality, expertise and support. Accordingly, the company has received an order worth over £75,000, which covers more than 30 different styles of custom developed tool, including replaceable blade, carbide and PCD types.
