Abstract
Official abstract text for this publication.
An abrasive element comprises a body of crystalline abrasive material. The body has an array of cutting elements formed of crystalline abrasive material which projects from a surface of the body. The shape, size and form of the projections is controlled in the production process. The body may be a natural or synthetic crystal. The body may be a film formed by deposition. The body may be diamond or cubic boron nitride. The body may be monocrystalline or polycrystalline. The projections may be aligned along a crystallographic plane or planes.
First claim
Opening claim text (preview).
The invention claimed is: 1. An abrasive element comprising a monocrystalline body of abrasive material having an array of cutting elements formed as projections of the monocrystalline abrasive material at a surface of the body, the array including a line of projections aligned along a crystallographic plane, wherein at least some of the projections have curved tops. 2. An element according to claim 1 , wherein a plurality of the cutting elements have at least…
