Note : Using the touch screen, press the zones or buttons shown. OR Enter the correction value. Check the entered value RESULT = The lens is edged to the new dimension : HINTS Flow chart 3-8 : Entering an oversizing value 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 new lens : in both cases, the characteristics of the first lens to be edged are saved and applied to the second lens. Example : Edging the same lens twice. Retouching corresponds to a negative size correction value applied during a second edging to the diameter of the lens initially edged 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 ALTA NX 3-79

Zone inside which drilling is allowed. Note : If a job includes a hole wich cannot be drilled (Hole positionned in the axis end fittings, notches going through the center of the shape, etc...), this hole will be displayed in black. Some holes displayed in blue when the shape is called up, may be undrillable after the lens has been felt (Hole too deep, unapropriate angle, unapropriate axis end fitting fitted, etc...). In this case, those holes will be displayed in gray and simply pointed by the end of the drill bit (tilted to maximum) during the drilling phase, this after 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 : Max. distance drill bit centre -> edge of lens = 12 mm Zone inside which drilling is banned.

Note : If a job includes a hole placed at a distance of more than 12 mm from the edge of the shape, the following message is displayed : "Hole deleted. At least one of the holes cannot be drilled. Do you want to continue?». If you reply Yes : The entire drilling plan is ignored, the lens is not drilled and finished in rimless. If you reply No, you can remove the lens from the drilling chamber. ALTA NX 3-97

100 Using your ALTA...Operating range 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 parameters can 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 results in a blind hole. Attention! Blind hole for lens thickness > 8 mm Exemple : 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 the hole may be blind. Example : Drilling 19 mm from the blocking centre at 0 in a lens of strength +7 D will produce a through hole. The quality of the final job (respect of the gaps, the axis, the diameter and the 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 adhesif patches ; > correct data entry and adjustment of centering, blocking, edging and drilling of the lenses.
