Abstract
An improved method for lapping the facets on a hard material such as a diamond provides faster machining and reduced crystallographic sensitivity. The improved method uses a lapping disc coated with an abrasive slurry, which lapping disc comprises a ternary alloy of aluminum, silicon and iron, and which alloy may be oxidized for even further enhanced lapping of the diamond.
