1. INTRODUCTION

The MAXIMA system introduces a new generation of INDO edging systems destined to the cut of ophthalmic lenses.

Its wide range of features, advanced technology and innovative design give it an unmistakable charm.

Within the MAXIMA system, the COMBIMAX Tracer-Blocker uses 3D digital technology. The shape of rims and the curvature of the frame can be seen in real time and simultaneously for both eyes.

By means of a high resolution TFT colour screen, it supplies necessary information in a clear, logic and comfortable way.

Users will thank, without any doubt, this new way of operation.

2. SYSTEM CONFIGURATION

2.1 SINGLE CONNECTION

To connect MAXIMA system in single mode (usual mode), MAXIMA or OPTIMA edger must be connected to COMBIMAX through communication cable 2114/482 (C28), supplied together with the COMBIMAX. This cable is 3 meters long (see Fig. 1)

FIG.1

2.2 NETWORK

For high productions, MAXIMA system allows a network connection, linking many edgers to a single COMBIMAX.

It is recommended to connect a maximum of three MAXIMA edgers to a single COMBIMAX, so that the operation time of every unit will remain balanced.

To connect many edgers to a COMBIMAX it is required a Multiple connection Kit. This one links up to three MAXIMA edgers to a single COMBIMAX (see Fig. 2).

3. DESCRIPTION OF PROCESSES

The COMBIMAX, makes a job in three basic steps: Reading of shape, centring and blocking.

First process: Reading of shape

The frame is inserted between the clamping pincers and the reading process is activated. The COMBIMAX proceeds to read, simultaneously, the contour of both frame’s rims, as well as their curvature.

This information will be used to calculate the exact contour of the frame rims, so that the work in the edger and the subsequent assembly will be as exact as possible.

During this phase is possible to introduce the data of the off-centring as well as the reference of the job, that will be used to identify said job upon calling it from the edger.

Second process: Centring

Once the reading process is finished, the centring process starts. In this step, the lens is placed within the centring zone, supporting it in the three feet of the tilting holder. Then retention clamp is lowered down, so that the lens remains well fixed in the moment of the blocking. The blocking process can be done by two procedures: Automatic or Manual. In the automatic process, the marks of the lens are recognised in an automatic way, so the off centring is calculated in function of the position in which the lens is placed. It is enough locating the lens in an approximate way. The system will make the rest.

Nevertheless, if the automatic system, by some reason, does not achieve to detect the marks, it is possible to perform the centring process by the customary method, locating the lens with respect to some reference marks that appear in the screen.

Third process: Blocking

The blocking is the final step, in which the blocking knob is placed on the lens. After blocking, the job is saved in the memory, so that it can be recalled from the edger for its edging.

7.1. HOW TO READ A FRAME

Reading Copy Eye to Eye to Stop

activation selection Copy Block Reading

To read a frame proceed as follows:

a) Place the icon of copy selection in "Frame" (the frame of the upper part of the icon remains on yellow background, while the pattern of the lower part remains in grey). "Frame" is the default selection.

b) With the key corresponding to the "Eye to copy" icon, select both (default selection), right or left. It is recommended to trace both eyes as long as it is possible, since this is the way to obtain automatically the value of frame’s bridge.

c) With the key corresponding to the icon of "Eye to block" select both (default selection), right or left, according to the case.

The status bar shows the icons:

d) Open the gags to the maximum and place the frame so that it is located within the pincers. Place first the lower part of the frame and then, move the gags closer and, at the same time, turn the frame until making to encase it within the pincers of the upper part. Close the gags until the frame remains flat and touches the walls, without forcing the position.

e) Press START to activate the copy. The icon changes to STOP, permitting to cancel the copy if it would be necessary. A process of copy cancellation must be confirmed with ENTER. After this, screen will return to the first group of icons.

During the copy process, the read form is shown in the screen in real time, together with the curvature of both rims. Once the reading operation ends, the equipment passes automatically to the centring screen.

WARNING!

7.2. HOW TO READ A PATTERN OR DEMO-LENS

Reading Copy Eye to Eye to Stop

activation selection Copy Block Reading

To read a frame proceed as follows:

b) Place the pattern’s extend accessory, encasing it deep in the stylus of the left eye.

c) The "Eye to copy" icon turns automatically to left eye, what corresponds with the position of the pattern.

d) With the key corresponding to the icon of "Eye to block" select both (default selection), right or left, according to the case.

The status bar shows the icons:

e) Put the pattern or demo-lens on the adapting holder, so that the nasal part stays toward the inside and the eyebrow as the frame. Then open the gags to the maximum, to insert the adapting holder within the pincers and shift it laterally until it fits.

f) Press START to activate the copy. The icon changes to STOP, permitting to cancel the copy if it would be necessary. A process of copy cancellation must be confirmed with ENTER. After this, screen will return to the first group of icons.

During the copy process, the read form is shown in the screen in real time, together with the curvature of both rims. Check-up, observing in the screen that the position of the nasal part remains toward the inside.

Once the reading operation ends, the equipment passes automatically to the centring screen.

7.3. DATA ENTRY

There are two types of data: patient data and data for work programming.

a) Patient data:

It is possible to enter patient data in any moment during the reading process. COMBIMAX does NOT enter in the centring screen until data necessary to calculate off-centring have been entered. However, it is possible to modify those data in this last screen, but always before starting the lens processing.
