The intuitive user interface and graphical guidance make the National Optronics 7E accessible for technicians with varying experience levels. This ease of use minimizes the learning curve and reduces operational errors.

National Optronics 7E Specifications

Drilling National Optronics 7E Edger  is a streamlined state of the art Patternless Edger with drilling capability. The angle of the drill is
designed to cut perpendicular to the front surface of the lens. This technique provides excellent frame fit
and an aesthetically pleasing product. The 7E can drill up to 6 holes in each lens, in hole diameters or slot widths ranging from 1 mm to 5 mm. The edger can quickly drill accurate, clean and chatter-free holes in all lens materials without requiring a bit change.
User Friendly The Windows-like format is easy to use and the PC-based software accumulates reliable and accurate data for customers. National Optronics 7E Edger is fully compliant with the current OMA standard. It can store an edger-resident
database which permits adding and editing frame information as well as downloading drilling parameters from databases. The 7E offers a Help screen for maintenance functions and operating instructions for inexperienced operators.
Design Features National Optronics 7E Edger has a 15” color flat panel LCD on an adjustable hinge for multi-positioning of the viewing angle. Hole placement for drilled lenses is displayed for viewing and/or adjustments. The modular design isolates the electronics and cutter motor from the cutting chamber.
Dry-Cutting Accuracy & 3-Axis Control
  • The unique dry-cutting accuracy and three-axis control features of the National Optronics 7E Edger allow the operator to process any CR-39, Polycarbonate, Hi-Index, and Trivex lens material faster and more accurately than most wet edgers and there are no messy coolants.
  • Because the blades cut, not grind the lens edge, there is no rounding of the lens bevel, leading to tighter fit and better interface with the groove of the frame. The new 20mm diameter cutter utilized by the 7E provides superior bevel reproduction on high base lenses and allows for accurate edging of many complex shapes.
New Feature Option A new feature of the National Optronics 7E Edger is the multi-fluted cutter.
Electric Chucking Electric chucking will automatically adjust clamping pressure depending on the lens material.
Coated Carbide Cutter An extended-life coated carbide cutter comes standard with each 7E, thus increasing the number of jobs that can be processed on one blade. A PCD cutter is optional.
  • Fully interfaceable with most 3rd-party software packages. OMA compatible.
  • Accepts barcode job entry (barcode optional).
