Abstract
(EN)
Provided is a machining jig on which a carbon membrane (3) is formed on the machining face of a rigid substrate (1), and that is characterized in that the carbon membrane (3) shows a Raman spectroscopy spectrum with an intensity ratio, as expressed by the formula ID/IG (wherein ID is the maximum peak intensity at 1333 ± 10 cm-1 in the Raman spectroscopy spectrum of the carbon membrane surface, and IG is the maximum peak intensity at 1500 ± 100 cm-1 in the Raman spectroscopy spectrum of the carbon membrane surface), exceeding 0.6. Also provided is a method for manufacturing seamless can bodies that is characterized by including a step of using a mold machining member, on which a diamond membrane is formed on the machining surface, to press machine a metal material onto the machining surface of the mold machining member with coolant being interspersed therebetween.

L'invention concerne un gabarit d'usinage, une membrane de carbone (3) étant formée sur la face d'usinage d'un substrat rigide (1), et le gabarit d'usinage étant caractérisé en ce que la membrane de carbone (3) présente un spectre de spectroscopie Raman doté d'un rapport d'intensité, tel qu'exprimé par la formule ID/IG (ID étant l'intensité maximale de pic à 1333 ± 10 cm-1 dans le spectre de spectroscopie Raman de la surface de la membrane de carbone, et IG étant l'intensité maximale de pic à 1500 ± 100 cm-1 dans le spectre de spectroscopie Raman de la surface de la membrane de carbone) dépassant 0,6. L'invention concerne également un procédé de fabrication de corps de boîte sans soudure, qui est caractérisé en ce qu'il comprend une étape consistant à utiliser un élément d'usinage de moule, une membrane en diamant étant formée sur la surface d'usinage, en vue d'usiner à la presse un matériau métallique sur la surface d'usinage de l'élément d'usinage de moule, un agent de refroidissement étant intercalé entre ces derniers.
