The National Optronics 7E is an automated patternless lens edger engineered for precision optical processing in laboratory and retail settings. This system combines three-axis milling technology with intelligent shape management to deliver accurate lens cutting, drilling, and beveling across multiple materials. The machine processes CR-39, polycarbonate, hi-index, and Trivex lenses while employing dry-cutting technology to eliminate coolant mess and maintain consistent edge quality.
Technical Specifications
Edging & Milling
• Three-axis control system
• Extended-life coated carbide cutter: 20 mm diameter (standard)
• Optional PCD or multi-fluted cutters available
• Dry-cutting technology throughout
• Fast and efficient cycle times
Shape Management
• Intelligent database capacity: 10,000 shapes
• Patternless operation for design flexibility
Drilling Capability
• Integrated drilling system — no bit changes required
• Up to 6 holes per lens
• Hole diameter and slot width range: 1 mm to 5 mm
• Drill angle perpendicular to lens front surface for optimal frame alignment
