Sigma Clermont se dote d’un centre d’usinage du titane sans équivalent (FR)

Posted on by

Après son exposition au Salon EMO d’Hanovre (Allemagne) du 18 au 23 septembre 2017, les premiers éléments du nouveau centre d’usinage de titane multi-axes Flexia V ont été livrés au début du mois d’octobre à SIGMA Clermont. L’assemblage se poursuivra jusqu’à la fin d’année 2017 pour une mise en service début 2018.

Mécaniciens des matériaux et des structures, roboticiens, informaticiens et spécialistes de la production manufacturière sont d’ores et déjà à l’œuvre sur la plateforme technologique de l’école pour imaginer les solutions de demain. Les industriels sont également associés au projet, notamment Aubert & Duval, qui a inauguré dernièrement à Saint-Georges-de-Mons (Puy-de-Dôme) une usine de recyclage du titane unique en Europe. SIGMA Clermont a également noué un partenariat avec Airbus et Safran. D’autres collaborations sont prévues dans la durée, sachant que l’exploitation de la machine, sa maintenance et la fourniture du support technique sont assurées par l’école.

Cette machine, acquise dans le cadre du projet RoMaPAR+ du CPER (Contrat de plan Etat-Région) 2015, aux caractéristiques exceptionnelles (courses de 2 mètres, puissance de broche de 100 kW), est la premièreContinue reading→
