48Working closely with leading edge companies, Chardon Tool has developed a broad and unique range of capabilities in its manufacturing processes for diamond tools.

Some of our current capabilities include:

  • precision1Convex and concave radii
  • Conical and cylindrical radius relief
  • Included angles as small as 2 degrees
  • Controlled edge waviness as low as 0.1 microns
  • Measure and document radius size to 1 micron accuracy
  • Measure and map the shape of diamond tools at the cutting edge using non-contact proprietary measuring software
  • precision2Produce and measure included angles on diamonds to tolerances of few arc minutes
  • Diamond cutting edges that are chip-free at under differential interference microscopy at magnifications up to 5000X
  • Check flatness of diamond cutting edges using microscope based interferometry
  • Produce diamond surfaces flat to 0.1 microns, with a roughness of less than 2 nanometers Ra


These tools are used for applications such as:

  • precision-product-2Diffractive optics
  • Contact lenses
  • Precision molds
  • Fresnel lenses
  • Medical optics
  • Micro-structural optics
  • Electro-optics
  • Intra-ocular lenses
  • Laser scanner mirrors
  • Concave aspherics
  • Concave hemispherics
  • precision-product-1Hard turning
  • Flycutting
  • Wear parts
  • Gage tips
  • Laser optics
