Abstract
ABSTRACT
An abrasive article such as a grinding wheel, disc or like tool is made up of metal objects such as rivets, staples or studs imbedded in a backing member and abrasive particles such as diamond or cubic boron nitride particles are electroplated onto exposed surfaces of the metal objects to provide a distribution of abrasive conglomerates over one surface of the article.

Claims (10)
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. An abrasive article comprising a plurality of metal objects imbedded in a carrying material so that at least a part of each metal object is exposed on a surface of the carrying material and abrasive particles adhered directly to said exposed parts of the objects by deposit of metal to provide a distribution of abrasive conglomerates over said surface.
2. An abrasive article as claimed in claim 1 wherein the metal objects are selected from the group consisting of staples, studs and rivets.
3. An abrasive article as claimed in claim 1 wherein the carrying material is a synthetic plastics material.
4. An abrasive article as claimed in claim 3 including a metallic sheet on the opposite surface of the synthetic plastics material in contact with terminal portions of said metal objects.
5. An abrasive article as claimed in claim 1 or 2 wherein the carrying material is a metallic material.
6. An abrasive article as claimed in claim 1, 2 or 3 wherein the carrying material is a flexible material.
7. An abrasive article as claimed in claim 1, 2 or 3 wherein the abrasive particles are selected from the group consisting of diamond particles and cubic boron nitride particles.
8. An abrasive article as claimed in claim 1, 2 or 3 in which the abrasive particles are diamond or cubic boron nitride particles and the metal objects are metal studs, rivets or staples.
9. A method of manufacturing an abrasive article which comprises adhering abrasive onto metal objects either before or after affixing such metal objects onto a carrying member, the adherence of the abrasive particles onto the metal objects being achieved by the electrodeposition of metal onto said metal objects.
10. A method as claimed in claim 9, in which the abrasive particles are selected from diamond and cubic boron nitride and the metal objects are selected from metal studs, rivets and staples.
