11. Manual lens clamping
Press and hold to close the lens clamp shafts manually.
12. Start the edging cycle
The door closing and lens clamping are automatic.
Always browse from left to right: depending on your selection, certain menus will be available while
others will not.
Your habits taken into account
The edger memorises your working habits: as time goes by, the buttons of the functions you use most
often will be displayed by default.
b. Calling a shape
There are 3 ways of calling the shape you want to edge:
• Calling the current job:
> Press to display the shape being processed on the tracer.
• Calling the number of a shape saved on the tracer:
> Press for a few seconds on to open the numeric keypad.
> You can then call a shape via the ID allocated to it.
• Job call via a barcode:
> Scan the barcode using the barcode reader (optional).
Always block your two lenses before proceeding with the edging. If a job in the course of modification on the
tracer (display of the symbol beside the reference) is called on the edger, a warning message is
displayed.
> Press to continue and display the job on the edger. The modifications underway are then ignored.
> Press to prevent the display of the job and finish the modifications underway on the tracer.
A reminder of the type of posiblock required is displayed on the shape. It is crucial to use the proper
accessory to edge the lens. Otherwise, an error message is displayed at the start of the cycle.

USER MANUAL> II. EDGING A LENS
c. Lens set-up and feeling
Prerequisite: the lens must be centered and blocked before placing it in the edger.
Check that the posiblock holder and the stop correspond to the posiblock used. Otherwise, you will need
to remove them form the lens clamp shafts and replace them with the tools matching the diameter of the
posiblock.
• For a 22 mm posiblock • For an 18×14 mm posiblock
Place the lens in the posiblock holder.
Place the metal peg of the posiblock upwards and the positioner downwards: a magnet is used to
hold the lens in position on the axis.
You can clamp the lens manually by pressing : Manual lens clamping is particularly suited to
hydrophobic lenses, thick lenses and high-camber lenses, as it ensures that the lens won't come
off the pad before clamping.
Make sure you move your hand well away before you start the edging cycle.

Press .
The door closes then the lens clamping operation starts.
The size of the posiblock holder is checked then the feeling cycle starts.
To interrupt the feeling cycle at any time, press .
As the lens is felt, its shape appears on screen. The double tracing represents the profile of the front
surface of the shape (inner shape) and its rear surface (outer shape).
In the case of edging mode selection:
• automatic, you do not have anything to configure, all the data is automatically recovered from
the tracer. The lens edging starts automatically after the feeling cycle.
• customized, the finish parameters can be fully customized.
For further information, refer to the section concerning your type of finish.
2. BEVELING
This section describes the procedures for creation of a bevel:
• In automatic mode (F p.21), you do not have anything to configure. All the data is automatically
retrieved from the tracer. The lens edging starts automatically after the feeling cycle.
• In customized mode (F p.22), you can opt for front/rear surface tracking, a distributed bevel, lens
curve tracking or rim tracking. You can also do the following:
◦ a total modification of the bevel curve (F p.25)
◦ a modification at a point of the bevel curve (F p.26)
◦ a displacement of the bevel curve (F p.27)
• You can consult the description of the customized bevel screen. (F p.22)

b. Legend screen for customized bevels
1. Automatic bevel
2. Customized bevels
◦ Front surface tracking: the crest of the bevel is positioned at a constant distance from the
front surface.
◦ Rear surface tracking: the crest of the bevel is positioned at a constant distance from the
rear surface.
◦ Distributed bevel: the position of the crest of the bevel is proportional to the thickness of
the lens, with respect to the front surface.
◦ Frame rim tracking: the bevel tracks the groove precisely, according to the data obtained
on frame tracing.
3. Lens thickness
◦ Maximum lens thickness - represented by the white square along the shape.
◦ Minimum lens thickness - represented by the red square along the shape.
4. Cursor movement
The cursor is represented by the green square along the shape. To move it, select it directly or use the
and buttons.
5. Zoom window
Represents the bevel profile and indicates the distance between the bevel crest and the front and rear
surfaces of the lens at the cursor position.

c. Customized beveling
The use of the customized bevel depends on 2 parameters: the frame and the lens. Before starting your job,
identify the major constraint.
BEVEL FRAME LENS ADVANTAGES
Classic Lens for which the front surface base
is approximately equal to the frame
base.
Makes it possible to do an
aesthetically pleasing job. The lens
material does not protrude beyond
the front of the frame.
Classic Lenticular lens&, Executive lens
&
Makes it possible to do a job with
specific lenses.
Classic Thin lens Makes it possible to balance out the
bevel when thin lenses are used.
Particular
groove (groove
with
meniscus&)
Thin lens for which the base is
approximately equal to the meniscus
of the groove.
Compliance with original shape.
Job using a specific frame.
Call the desired shape located on the tracer.
