Les mandrins motorisés sont des mandrins utilisés pour l'usinage de coupe et/ou de rectification sur machines-outils ou centres d'usinage. Contrairement aux mandrins manuels , leurs mâchoires de serrage s'ouvrent et se ferment automatiquement. Un vérin hydraulique/pneumatique, commandé par la machine, actionne le mécanisme d'ouverture/fermeture du mandrin.
