The removal of material from a substrate using a single
crystal natural diamond cutting tool has been experimented
with in the United States for over 4 0 years.
However, the most significant advances in this technology
have taken place in the last decade. Today, single point
diamond turning is recognized as a well established, cost
effective, and repeatable manufacturing process. A wide
variety of optical components, as well as mechanical components
requiring micro-inch dimensional tolerances, are
produced through single point diamond turning.
