IMITS RELATED TO THE THICKNESS OF THE LENS
The position of the hole and the strength of the lens to be drilled effect the drilling depth. These two parameters
can cause non-through holes which must then be finished manually.
→
Thick lenses ( = thickness in the direction of drilling > 8 mm )
For lenses of high thickness and for high drilling radii (distance from centre of block to centre of hole),
it is possible that the maximum drilling length in the drilling direction may be exceeded. This results
in a non-through hole.
Example: Drilling 30 mm from the blocking centre at 0° in a lens of strength -7 D will produce a
through hole.
→
Lenses with high front base
For lenses of high front base and for high drilling radii (distance from centre of block to centre of
hole), it is possible that the mill bit retaining nut may interfere with the lens. If so, the edger
automatically limits the drilling depth to avoid this type of damage to the lens. However this may
produce a non-through hole.
Example: Drilling 19 mm from the blocking centre at 0° in a lens of st7 D will produce a
through hole.
The quality of the final job (accuracy of gaps, axis, diameter and angle of drilling)
depends on the performance and the quality of all the elements in the chain:
> The quality of the frame used and its presentation lens
>
The use of new Briot blocks and adhesive patches
> Correct setting of entry, lens centering, blocking, edging and drilling data.
