Natural Diamond Cutting Tools - The Search For Consistency

Gone are the days when virtually the sole requirement of a single point diamond cutting tool lay in its ability to generate a cosmetically pleasing surface - components used in the Electro Optics Industry and other high technology areas demand very much more than this but of all the factors involved in the manufacture of these high precision tools, the achievement of predictable and consistent cutting edge life has emerged as one of the most vital and probably the most difficult to achieve. In this paper we examine various critical stages in manufacture and look at the means which have been developed to achieve consistent tool performance with predictable life between relaps.
