Abstract

L'invention concerne un outil de polissage permettant d'effectuer la finition du polissage d'une surface d'article à un degré de rugosité de surface désiré. Une pluralité de feuilles (7) de tissu de polissage sensiblement circulaires sont superposées afin de former un élément de polissage (3) sensiblement cylindrique. Le bord périphérique de chaque feuille (7) se présente sous forme de méandres effectuant un mouvement de va et vient axial par rapport à un arbre central. La forme développée du bord extérieur de chaque feuille (7) se présente sous forme d'une courbe sensiblement en S. L'élément de polissage (3) tourne afin de polir un article à partir de sa surface périphérique. Du fait que le polissage s'effectue par déplacement axial du bord extérieur de chaque feuille (7) de tissu de polissage, lesdits bords périphériques viennent en contact avec la totalité de la surface à polir. Les feuilles (7) de tissu de polissage sont polissables entre elles de sorte que la surface à polir est polie à un dégré de rugosité de surface désiré.
