SGX Plus Surface Generator

The SGX Plus Surface Generator provides progressive labs around the world with proven, high-performance cutting technology for CR39, hi-index, and polycarbonate lenses. Compact and intelligent, the SGX Plus processes all lenses totally free of elliptical error. Its computer-controlled precision provides a low-stress means of generating exact prescription curves. Additionally, the SGX Plus uses Gerber Coburn's three-axis, dry cut method of lens generating to ensure superior lens quality, while creating less mess in the lab.

To meet the diverse needs of its growing global customer base, the SGX Plus now offers an extended processing range, new 50/60 Hz brushless motor, small diameter lens cribbing, lower cost auxiliary components, and an all material, longer life, 9-flute cutter.

Surfacing Unit

   The SGX Plus calculates the surfacing tool path for the lens and its exact matching lap at the touch of a button. The SGX Plus also generates lenses in
    sizes up to 90 mm in diameter and 20 mm in thickness, and easily cuts the flatter curves required by aspheric lenses-thereby enhancing overall lab
    versatility.

  Built-in keypad with two-line LCD display provides a simple user interface and helpful text messages to guide operators through the entire process.

  Full size keyboard or optional bar code wand allows fast, easy data entry.

  New 50/60 Hz brushless motor eliminates routine brush replacement and maintenance.

  Full job overlap for batch processing of jobs increases surfacing productivity.

  Safety bevel selection provides automatic chamfering of the lens.

  Compatibility with Gerber Coburn Innovations™ Software and third party lab layout computers allow automatic transfer of surfacing data, job storage,
   and lab management.

  Hands-free operation allows the operator to perform other tasks in the lab while the lens is being generated.

  Intuitive design minimizes training time and enables operators with little knowledge of optics to produce consistently accurate results.
 

Three Axis Generating

   The SGX Plus reduces total surfacing time by shortening fining and polishing cycles, and enabling consistent single-step fining of most lens materials.

  Curves for virtually every ophthalmic prescription are cut without prism marking, blocking or rings, making it easier for the operator to manage each
   job, and further reducing the opportunity for errors.

  Precise 3-axis machining generates consistently accurate prescription curves. Exact prescriptions are cut with a New extended lens and lap curve
   processing range of +8.00D to -30.00D.

  Improved process controls require fewer operator decisions, reducing the potential for errors and rejects.

  Lenses are blocked on geometric center, which simplifies the blocking process.
 

Laps

   The SGX quickly cuts hard plastic laps or Gerber Coburn's disposable foam LapMasters™ for any lens, thereby eliminating the need to maintain a
    conventional lap inventory.

   LapMasters can be used for non-typical curves, which reduces the permanent inventory of hard lap tools that must be maintained.

   Retrue mode allows labs to recut lap tools thereby maintaining the overall finish and curve quality of the lap inventory

Cutting Process

   Three-axis, three dimensional contouring tools ensure accuracy and reliability. The durable fluted precision cutter is specifically designed for cool,
    efficient cutting of lenses. New 9 flute All material cutter gets 1,000* lenses per tool.*

   Vortex chiller blows cold air at the cutter ball during surfacing to regulate the temperature of the cutting chamber, cool the cutter and remove dust.
    This allows cleaner, cooler lens processing, which prolongs tool life and minimizes breakage.

   SPECIALS function prevents edge chipping when processing progressives, executives, aspherics and knife-edge lenses.

   CR-39, Polycarbonate Trivex, and Hi-Index lenses can be generated interchangeably.
