Title
(EN) REUSABLE HUB ASSEMBLY FOR ABRASIVE ARTICLES
(FR) ENSEMBLE MOYEU RÉUTILISABLE POUR ARTICLES ABRASIFS
Abstract
(EN) A method of reusing a hub in an abrasive assembly is presented that includes removably coupling the abrasive wheel to a reusable hub. The abrasive wheel has an outer circumference and an inner circumference. The abrasive article has an inner circumference and an outer circumference. The method also includes abrading a worksurface by contacting the abrasive wheel to the worksurface. The reusable hub includes a coupling feature configured to directly couple to the abrasive article. The coupling feature includes an adhesive-free connection between the reusable hub and the abrasive wheel. The direct connection is a removable interlocking between the abrasive wheel and the reusable hub.
(FR) L'invention concerne un procédé de réutilisation d'un moyeu dans un ensemble abrasif qui comprend l'accouplement amovible de la roue abrasive à un moyeu réutilisable. La roue abrasive présente une circonférence extérieure et une circonférence intérieure. L'article abrasif présente une circonférence interne et une circonférence externe. Le procédé consiste également à abraser une surface de travail en mettant la roue abrasive en contact avec la surface de travail. Le moyeu réutilisable comprend un élément d'accouplement conçu pour être accouplé directement à l'article abrasif. L'élément d'accouplement comprend une liaison sans adhésif entre le moyeu réutilisable et la roue abrasive. La liaison directe représente un emboîtement amovible entre la roue abrasive et le moyeu réutilisable.
