Zusammenfassung:The present invention provides a grinding wheel which has excellent grinding efficiency and enables stable grinding for a long period of time.ãA glass filler-containing metal bond grinding wheel (10) according to the present invention has a metal bond layer (14) that contains abrasive grains (11), a metal bond (12) and a glass filler (13). This glass filler-containing metal bond grinding wheel (10) is configured such that: the abrasive grains (11) are composed of diamond and/or cubic boron nitride; the metal bond (12) is composed of a metal that contains Cu; the ratio of the volume of the glass filler (13) to the volume of the metal bond (12) is from 0.025 to 1.0 (inclusive); and the metal bond (12) and the glass filler (13) are mutually diffused. Se proporciona una muela abrasiva con un excelente rendimiento de rectificado y que proporciona un rectificado estable durante un largo período de tiempo. Una muela abrasiva con aglomerante metálico que contiene relleno de vidrio (10) incluye una capa de aglomerante metálico (14) que incluye granos abrasivos (11), un aglomerante metálico (12) y un relleno de vidrio (13). La muela abrasiva con aglomerante metálico que contiene relleno de vidrio (10) tiene granos abrasivos (11) que son diamantes y/o nitruros de boro cúbicos, el aglomerante metálico (12) es un metal que contiene Cu, la relación entre el volumen del relleno de vidrio (13) y el volumen del aglomerante metálico (12) es de 0.025 o más a 1.0 o menos, y el aglomerante metálico (12) y el relleno de vidrio (13) se difunden mutuamente.
