Contour Fine Tooling has developed a complete range of tools to meet the requirements of today’s contact lens manufacturer. For optimum cutting efficiency the correct tool geometry must be used for any given material. Available with either natural or synthetic single crystal diamond, a range of radius size and rake angle is offered. Tools can either be solid or insert style; they have a standard arc of 120° although larger angles are available. Contour Fine Tooling orientates the diamond to maximise the wear-resistant characteristics.

The radius, although not controlled in terms of waviness, is generated to be smooth and facet-free. The edge is inspected to be chip free, at x500 Nomarski. Standard Tools can also be used for roughing operations
