A CNC Machining Center for Processing Aluminum Profiles for the Train Industry

Giovanni Barbareschi, Tekna Srl

Track: VALUE-ADDED PROCESSES - Fabrication

ABSTRACT --- In recent years the use of aluminum extrusions in the train vehicle frames
has increased. The successful development of aluminum alloys, extrusion profiles and
new welding technology (Friction Stir Welding) has lead the train industry to extensively
replace the steel frames with aluminum frames. This has allowed the production of lighter
train vehicles whose components are made of recyclable material. The extensive use of
aluminum in the train industry is now an opportunity for the introduction of new production
processes considering that the machining of aluminum does not require as much power as
the machining of steel. This paper presents a CNC (computerized numerical control)
machining center, which has been specifically developed for the processing of long
aluminum extrusions for the assembly of train vehicles. The main characteristics of this
solution are agility, limited power and suitable accuracy. Comparing to the processing
solutions traditionally used by the train industry, this Machining Center allows a higher
productivity with a lower capital investment.
