Hydro Exploitations : Challenges for the polymechanics

As a result of the numerous technical challenges they regularly receive, our Central Workshops in Martigny have invested in a new 5-axis machining centre from Correa (milling + turning). In terms of its size and level of precision there is no other installation like it in French-speaking Switzerland.

Three machines are now dedicated to large parts, which can weigh up to 20 tons:

• CNC milling machine (max. diam. of 7m x 3m)
• Vertical lathe (max. diam. of Ø 2.8m x height 2.5m)
• Longitudinal lathe (max. diam. of Ø 0.8m x height 3m)

Thanks to these machines, Pierre-Yves Besse and Gilles Taramarcaz's team will be able to continue to successfully meet demand, 40% of which now comes from sectors other than hydroelectricity, as in these recent assignments:

• Interior plants /Machining of stainless steel half spheres with over 6000 holes for HBF-SA Metal System Solutions and its client,Photo Elysée(newly named Musée de l'Elysée).

• Aluminium production /Machining of complex parts used in aluminium casting. Engineering byGAP Engineering SAfor its clientConstellium Singen (DE)who produces a wide range of products for the packaging, transport and automotive markets.

• Railways /Manufacture of a clamping table for the mechanical workshopJacquier & Luisierand its clientRailtech, for bogie testing.

• Food /Welding and machining of a special 3.5 metre long cocoa butter production tank forMeili Technology SA.

• Cable transport /Repair of a ski lift pulley for thePomaGroup, world leader in its sector.
