Title
(EN) GRINDING WHEEL AND METHOD OF MANUFACTURING GRINDING WHEEL
(FR) MEULE ET PROCÉDÉ DE FABRICATION DE MEULE
Abstract
(EN)
Object: To provide a grinding wheel and a method of manufacturing a grinding wheel having added value while providing a suppressed manufacturing cost. Solution Means: The grinding wheel is a grinding wheel including an abrasive portion including nonwoven fabric, wherein the abrasive portion includes an outer peripheral portion formed with the nonwoven fabric including abrasive grains on an outer peripheral side, and an inner peripheral portion formed with the nonwoven fabric not including the abrasive grains, and a ratio of a thickness in a radial direction of the outer peripheral portion to a thickness in a radial direction of the abrasive portion is from 3% to 60%.
(FR)
Objet : La présente invention concerne une meule et un procédé de fabrication d'une meule ayant une valeur ajoutée tout en éliminant les coûts de fabrication. Solution : La meule est une meule comprenant une partie abrasive comprenant un non tissé, la partie abrasive comprenant une partie périphérique externe pourvue du non tissé comprenant des grains abrasifs sur un côté périphérique externe, et une partie périphérique interne pourvue du non tissé ne comprenant pas les grains abrasifs, et un rapport d'une épaisseur dans une direction radiale de la partie périphérique externe à une épaisseur dans une direction radiale de la partie abrasive étant de 3 % à 60 %.
