Claims
- 1. A method of making a coated abrasive article comprising the steps of:
- (1) introducing a slurry containing a mixture of a binder and a plurality of abrasive grains onto a production tool;
- (2) introducing a backing to the outer surface of the production tool such that the slurry wets one side of the backing to form an intermediate article;
- (3) at least partially curing or gelling the binder before the intermediate article departs from the outer surface of the production tool to form a coated abrasive article; and
- (4) removing the coated abrasive article from the production tool.
- 2. The method of claim 1, wherein said binder is cured by radiation energy.
- 3. The method of claim 1, wherein said production tool is cylindrical in shape.
- 4. The method of claim 1, wherein said production tool is a belt.
- 5. The method of claim 1, wherein said binder is cured by thermal energy.
- 6. The method of claim 1, further including the step of fully curing the coated abrasive article after removal from the production tool.
- 7. A method of making a coated abrasive article comprising the steps of:
- (1) introducing a slurry containing a mixture of a binder and plurality of abrasive grains on to a backing such that the slurry wets the front side of the backing to form an intermediate article;
- (2) introducing the intermediate article to a production tool having an outer surface, the outer surface of the production tool containing a specified pattern;
- (3) at least partially curing or gelling the binder before the intermediate article departs from the outer surface of the production tool to form a coated abrasive article; and
- (4) removing from the coated abrasive article from the production tool.
- 8. The method of claim 7, wherein said binder is cured by radiation energy.
- 9. The method of claim 7, wherein said production tool is cylindrical in shape.
- 10. The method of claim 7, wherein said production tool is a belt.
- 11. The method of claim 7, wherein said binder is cured by thermal energy.
- 12. The method of claim 7, further including the step of fully curing the coated abrasive article after removal from the production tool.
- 13. A method of abrading a surface of a workpiece comprising the steps of:
- (1) providing a coated abrasive article comprising a backing having attached to at least one major surface thereof, in an array having a non-random pattern, a plurality of precisely shaped abrasive composites, each of said composites comprising a plurality of abrasive grains dispersed in a binder, which binder provides the means of attachment of the composites to the backing;
- (2) placing the surface of said article having abrasive composites attached thereto in contact with the surface of said workpiece; and
- (3) moving at least one of the surface of said article or the surface of said workpiece with respect to the other so as to abrade the surface of said workpiece.
- 14. A method of abrading a surface of a workpiece comprising the steps of:
- (1) providing a coated abrasive article comprising a backing having attached to at least one major surface thereof, in an array having a non-random pattern, a plurality of precisely shaped abrasive composites, each of said composites comprising a plurality of abrasive grains dispersed in a binder, which binder is formed from a material curable by radiation energy;
- (2) placing the surface of said article having abrasive composites attached thereto in contact with the surface of said workpiece; and
- (3) moving at least one of the surface of said article or the surface of said workpiece with respect to the other so as to abrade the surface of said workpiece.
