Abstract
An abrasive article can include a core and an abrasive component attached to the core. The abrasive component may include a body including a leading end and a trailing end, wherein the leading end has a width greater than a width of the trailing end. In an embodiment, the abrasive component may include a body including a first abrasive portion and a second abrasive portion, wherein a radial width of the first abrasive portion is greater than a radial width of the second abrasive portion.
Claims20
An abrasive article, comprising a core and at least one abrasive component attached to the core, wherein the at least one abrasive component comprises a body including:
- a first abrasive portion including a leading end;
- a second abrasive portion connected to the first abrasive portion including a trailing end and a second circumferential length of at least 30% of a total circumferential length of the body;
- and
- an inner circumferential surface and an outer circumferential surface extending between the leading end and the trailing end, wherein the leading end and the trailing end extend between the inner circumferential surface and the outer circumferential surface,
- wherein:
- each of the leading end and trailing end has a width measured between the inner and outer circumferential surfaces, wherein the width of the trailing end is different than the width of the leading end;
- and
- the first abrasive portion comprises a first radial width measured between the inner circumferential surface and the outer circumferential surface, and the second abrasive portion comprises a second radial width measured between the inner circumferential surface and the outer circumferential surface, wherein the first radial width is greater than the second radial width.
An abrasive article, comprising a core and at least one abrasive component attached to the core, wherein the at least one abrasive component comprises a body including:
- a first abrasive portion including a leading end;
- a second abrasive portion connected to the first abrasive portion including a trailing end;
- and
- an inner circumferential surface and an outer circumferential surface extending between the leading end and the trailing end, wherein the leading end and the trailing end extend between the inner circumferential surface and the outer circumferential surface;
- and
- wherein each of the leading end and trailing end has a width measured between the inner and outer circumferential surfaces, wherein the width of the trailing end is different than the width of the leading end, and
- wherein the body comprises a transitional edge between the first abrasive portion and the second abrasive portion.
An abrasive article, comprising a core and at least one abrasive component attached to the core, wherein the at least one abrasive component comprises a body including:
- a first abrasive portion including a leading end;
- a second abrasive portion connected to the first abrasive portion including the trailing end;
- a third abrasive portion connected to the first and second abrasive portions;
- an inner circumferential surface and an outer circumferential surface extending between the leading end and the trailing end, wherein the leading end and the trailing end extend between the inner circumferential surface and the outer circumferential surface, and the leading end and trailing end have a different width measured between the inner and outer circumferential surfaces,
- wherein the third abrasive portion comprises a third radial width measured between the inner circumferential surface and the outer circumferential surface, wherein the third radial width is different from a first radial width of the first abrasive portion or a second radial width of the second abrasive portion or both.
