Multi-Access Edger (i.e. the 5-Axis Edging Machine)

Here we have the famous 5-axis edging machine – i.e. an automated lens cutting and surfacing machine that is capable running automatically and with less chance for human error. There are only a few of these in the world, and only two at Sola – one here and one in Italy. This machine has allowed Sola Technologies to make huge advances in shaping the edge of the sunglass lens to fit in a given frame. This has presented major difficulties in the past, and is the main reason that many sunglasses were once considered not Rx’able. Many of these limitations have now been overcome due to the agility / flexibility of this machine, and I have been told that the machine still has a lot more to offer.
Specifically, this machine operates a grinder or shaver on 5-axis (though some claim more) to manipulate the thickness of the edge of the lens such that it can fit in the prescribed frame. Currently, the frame shape is entered into the proprietary computer interface (partially shown in the foreground). The computer uses the selected frame shape, which has been specially programmed into the software, to dictate the eventual shape of the lens. It is important to note that each new frame, or frame variation, requires a new program to be tested / entered manually by the operator. This is no small task. Nike currently has ~10-15 frames programmed into the machine. This machine currently edges ~60% of all Sun Rx orders.
