Deburrer - Stadler Rail, storming the heights
The town of Bussnang in the Swiss canton of Thurgau is home to a company with more employees than the town's population. Some 2,200 people work for Stadler Rail, a company specializing in rolling stock and serving customers all around the world. The Stadler Rail Group with its six manufacturing sites - Bussnang, Altenrhein, Winterthur, Berlin, Siedlce (Poland) and Budapest - is active above all in the market segments made up of regional and inter-urban trains, light rail and street cars. What's more, the company intends to hold its premier position in the world's cog railway market.

That also convinced the operators of Switzerland's Glacier Express, which refers to itself as "the world's slowest express train". It links St. Moritz with Zermatt - via Chur, Disentis, Andermatt, Brig and Visp. This narrow-gauge train takes a good 7½ hours for the 291 kilometer route. 291 bridges, 91 tunnels and the Oberalp Pass at an altitude of 2,033 meters make its course a true adventure. There are postcard views at virtually every curve - particularly for passengers in the panorama car. During the most recent upgrade, in 2006, these cars were supplied by the Stadler works in Altenrhein. The list of references for Stadler Rail reads something like a who's who in the world of rail transport. That includes the German Railways, the Swiss National Railways and operators in the USA, Greece, Hungary, Italy and Algeria. The company's designs and concepts have found favor around the world.

Structures incorporating elaborate but, solid welds are indispensable for the quality of Stadler's rolling stock. The basis here is a clean surface at the welding edge, one free of any oxides. Until just a few years ago this was achieved with electric planning machines. But construction manager Bernhard Eisenegger was not particularly happy with that solution. As a result of the toughness of aluminum, these tools were forever becoming clogged and in need of cleaning.
When searching for alternatives some three years ago he discovered the TKA series of hand-held electric deburrers made by TRUMPF. The advantages of these power tools quickly convinced him and his associates. Eisenegger notes: "The TKAs can be used to machine a wide variety of contours. Even the smallest inside radii pose no problems. Burrs can readily be removed and the bevels have a clean visible edge. What's more, the TKAs are easy to use - even in overhead work such as when milling down both sides of the edges, 20 meters long, on the car roofs!"
