C.N.C. Multi Frontcurve Lathe


The CNC. Multi Frontcurve Lathe operates in a similar way to the Multi Basecurve machine except that it is dedicated to cutting multicurved convex lens surfaces. Loading of the blocked base curve and unloading the machine finished lens is carried out manually.

The C.N.C Multi Universal Lathe combines the functions of both the Multi Base and Multi Front machines and produces both multicurved concave and multi curved convex lens surfaces on the same machine.

The CNC Multi-Curve Lathe was developed for the production of Multiple spherical curves on either the Front or Back surfaces, via user friendly software. It is offered in two options:

  • Multi Universal for Front and Back Surface Cutting Ref. No: 5000 0008 (CNC Multi Universal Lathe)
  • Multi Base for Back Surface Cutting with Autoload.Ref. No: 5000 0007 (CNC Multi Base Curve Lathe) /li>

    CNC Multi Curve Key Features:

  • Fast cycle times to optimise production
  • High quality surface finish requiring minimal polishing.
