Gerber Coburn’s edging system lays out, blocks, traces, edges, drills, notches, and performs a host of supplementary services. Ed De Gennaro, MEd, ABOM
The Gerber Coburn Kappa CTd edger system is much more than a simple edger. This “intelligent” edging system automates many of the tasks opticians and technicians used to perform manually, and it does so with the precision only a computerized machine can provide while avoiding unique human errors like parallax and difficulty interpreting minute units. Here’s a look at a Kappa CTd in action creating a rimless pair of progressive lens eyeglasses.

1.
The Kappa CTd consists of two modules. The one on the left performs
layout, blocking, and tracing functions while the one on the right
handles the edging, drilling, grooving, notching, safety beveling, lens
polishing, and chamfering duties.
2.
Known as the Tracer/Blocker, the more slender module features a bright
display monitor that enables operator to enter job and patient data
with buttons below the screen.
3. The Tracer/Blocker will trace either a lens, lens pattern (former), or the frame.
Since the job being run here is a cord-mounted rimless, the operator
has mounted one of the frame’s insert lenses into a holder.
4.
With one of the lenses placed into the unit, the operator enters job
data into the system. Here you see monocular PDs and other job
information visible. The lens image on screen is the actual lens with
aligning markings superimposed on it.
5.
With the frame, lens, and patient data entered, the unit automatically
aligns for the lens’ axis and multifocal configuration and blocks the
lens.
6.
The operator “calls” up the job’s information by entering the job
number. Specialized settings can be entered now, including material
choices, grooving, notching, bevel positioning, and chamfering. Changes
to the lens’ shape can also be made.
7. Part of the edger’s “intelligence” comes from feeler gauges it uses during the preliminary edging cycle. Here you see them touch the lens as it spins. The cycle tells unit about the lens’ thickness and curvature.
8.
After having its diameter reduced and its shape created during the
roughing cycle, this rimless job gets a flat edge placed onto it during
the finish grinding cycle.
9. The unit places the groove into the lens for the nylon cord that will be used in this cord-mounted semi-rimless frame.
10.
This lens is drilled with the in-chamber drill unit. Once a hole is
drilled, the lens is “waggled” around to increase to required hole
size. Hole placement and size are adjusted using screen button inputs.
