Regrinding and Relapping of Single-Point, Single-Crystal Diamond Turning and Boring Tools

摘要

Single-crystal, single-point diamond tools have been successfully ground and lapped to specific geometries with chip-free cutting edges for producing mirror-like surfaces on nonferrous materials. It was found that the grinding and lapping facility required a special controlled environment and specially constructed grinding and lapping machines. Cleanliness was found to be of utmost importance. Special inspection techniques were used to ensure very accurate and repeatable measurements. Exceptional care is required in handling, grinding, lapping, inspecting, and packaging to prevent cutting edge chippage on the diamond. (ERA citation 08:012856)
