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>
