Exemple : If the job finishing is a bevel, the finishing displayed will automatically be Bevel.

> If the job does not provide edging data, the default characteristics (see Configuration of finishing default pa-rameters, chapter 4) will be displayed automatically.

Exemple : If the default finishing is Bevel and the type is Auto, the displayed finishing will be Beveland the sub-finishing Bevel Auto.

> If you modify the job data before starting to edge one of the lenses, the new characteristics will be memo-rised automatically and applied to the two lenses.

Attention ! Check the parameter values of the two lenses.

> The lens characteristics(material and type) determine the types of finishing available. Exemple : A mineral lens cannot be drilled. Drilling finishing is therefore not available in the finishings

pull-down menu when Mineral lens material is selected.

3.2.6.2 DURING EDGING OF THE SECOND LENS

⇒ Always check that the preselected type of finishing is the finishing that you wish to apply.

In fact, the finishing selected for the first lens is automatically memorised and preselected for thefollowing lens (see “Edging several lenses identically”, page 83 and see “Edging the left lens with dif-ferent parameters from those of the right lens”, page 82).

⇒ Check the parameter values.

Precision being the goal, as a con-sequence, the drilling time has been increased.The HD drilling has to be used each time the precision and the quality of the drilling are the most important and when the type of adhesive pad used for the job is a standard adhesive.The standard drilling, faster than the HD, offers the same precision as the HD drilling if and only if the type of adhesive used is 3M Leap 3 (0.6 mm thickness) or equivalent.

> Drilling, if it is selected, is the last step in the edging process. > Oblong holes and notches are always machined from the edge of the lens towards the centre. > Characteristics of the diameter of a hole : → The diameter of a drilled hole is always greater or equal to that of the mill bit which is fitted.

→ Special case : If the diameter of the fitted bit is greater than the diameter of the hole and you have confirmed the warning message "Bit diameter > hole diameter. Do you wish to drill ?", the hole diameter will be equal to the diameter of the bit.

→ A lens may be drilled in four ways :

> The drilling function allows drilling of the following special holes :

→ Countersinking is the superimposition of a blind hole over a through hole of smaller diameter.

> The smallest hole diameter that can be obtained with the ALTA NX bit is 1 mm.

> The total number of holes and notches is limited.

→ The limit is ten holes per lens, for all types of holes.

→ An oblong, a recess or a notch count for two holes.

> Retouching is not possible on a drilled lens. The Oversize/Retouching key is therefore inaccessible.

When the lens has been edged and you find that its diameter is too large for the frame, you may decide to reworkit by carrying out a retouch.

3.5.1.2 HOW ?3.5.1.2.1 PRIOR CONDITIONS

> The block must not have been removed from the lens when it was taken out of the edging chamber. > A lens with drilling data cannot be retouched.

= The lens is edged to the new dimension :

3.5.1.3 HINTS

⇒ Always check that the type of oversizing displayed - circumference or boxing width - is indeed that which you wish to apply.

⇒ Note the difference between re-edging a lens and retouching a lens :

Re-edging corresponds to a second edging of the lens previously edged, or the edging of a newlens : in both cases, the characteristics of the first lens to be edged are saved and applied to thesecond lens.

Example : Edging the same lens twice.

Retouching corresponds to a negative size correction value applied during a second edging tothe diameter of the lens initially edged.

3.5.1.4 IMPORTANT NOTES > The retouch value is negative by default (the sign "-" is already displayed on the numeric key board screen). > The retouch is applied to the width of the lens. The height of the lens is recalculated to retain the proportions

of the initial shape. > The selection of the type of retouch - to circumference or to boxing width - is done from the pull-down menus

⇒ Always check that the type of oversizing displayed - circumference or boxing width - is indeed that which you wish to apply.

3.5.2.4 IMPORTANT NOTES > The oversizing is applied to the width of the lens. The height of the lens is recalculated to retain the

proportions of the initial shape. > The selection of the type of oversizing - to circumference or to boxing width - is done from the pull-down

menus personalization menu (see Personalisation of pull-down menus, chapter 4). > The type of oversizing determines the type of retouching.

Exemple : if you select an oversize at the circumference, the retouch will also be made at thecircumference.

> For the same job, the oversizing applied to the right lens is not automatically applied to the left lens. > In the case of a new edging cycle for the same lens (also called"re-edging"), the oversizing applied to the

first lens will be automatically applied to the second.

> Only CR39, polycarbonate, high index (HI) and Trivex™ can be drilled. > A mineral lens cannot be drilled.

3.6.3.2 LIMITS OF HOLE POSITIONING

> Whatever the type of hole, it must be drilled in a specific zone which is defined following the diagrams below. > The following constraints must be respected :

→ the circle radius beyond which drilling is possible :

Note : If a job includes a hole wich cannot be dri l led (Hole posit ionned in the axis end f it t ings,notches going through the center of the shape, etc. . .) , th is hole wi l l be displayed inblack. Some holes displayed in blue when the shape is cal led up, may be undri l lableafter the lens has been felt (Hole too deep, unapropriate angle, unapropr iate axis endfi tt ing f i tted, etc. . . ) . In this case, those holes wi l l be displayed in gray and s implypointed by the end of the dri l l b i t (t i l ted to maximum) during the dr i l l ing phase, th isafter acceptation of the marking by the operator.

→ the ring formed by the edge of the lens and the internal perimeter of the lens beyond which drilling is forbidden :

ALL HOLES, WHATEVER THE TYPE, MUST BE WITHIN A 12 MM RING.

Note : I f a job inc ludes a hole placed at a distance of more than 12 mm from the edge of theshape, the fol lowing message is displayed : "Hole deleted. At least one of the holescannot be dr i l led. Do you want to cont inue? ». I f you reply Yes : The enti re dr i l l ingplan is ignored, the lens is not dr i l led and f in ished in r imless. If you reply No, youcan remove the lens from the dri l l ing chamber.

Zone inside which drilling is allowed.

ALTA NX 3-97


3.6.3.3 LIMITS 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 parameterscan cause blind 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 resultsin a blind hole.

Exemple : Drilling 30 mm from the blocking centre at 0° in a lens of strength -7 D will produce athrough hole.

→ Lenses with high front base

For lenses of high front base and for high drilling radii (distance from centre of block to centre ofhole), it is possible that the mill bit retaining nut may interfere with the lens. If so, the edgerautomatically limits the drilling depth to avoid this type of damage to the lens. However the hole maybe blind.

Example : Drilling 19 mm from the blocking centre at 0° in a lens of strength +7 D will produce athrough hole.

The qual i ty of the f inal job (respect of the gaps, the axis, the diameter and the angle ofdr i l l ing) depends on the performance and the qual i ty of al l the elements in the chain : > the qual i ty of the frame used and its presentation lens ; > the use of new Br iot blocks and adhesif patches ; > correct data entry and adjustment of center ing, blocking, edging and dri l l ing of the

lenses.
