If you have lenses that are not curing on the edges, it’s usually because of a dirty cure ring. The cure ring directs and amplifies the UV light towards the edge of the lens. Most users assume it’s a weak bulb. The wet edges will go away in some cases by replacing the bulb, but only because it’s putting out more energy. However this doesn’t address the underlying problem: the dirty cure ring.
To clean the ring, remove it from the machine and sandblast the inside. If you don’t have Anti-Reflective equipment, you may not have a sandblaster. In that case Scotchbrite will work just as well. Note that the cure ring will not look shiny after cleaning, but the oxidation film build up from the chemical reaction during the cure process will be removed. This will allow the cure ring to better direct and amplify the UV light towards the edge of the lens for proper cure with less energy or new bulbs.

Today’s digital equipment is much different than the generators and polishers of the past. When bringing in new digital equipment, it’s important to recognize that you may need to ask your lab technicians to change how they have been working as well. The new environment can appear challenging for operators used to performing the same functions for many years. Manufacturers offer on-site training when the equipment is being installed, which may be enough in some cases; however, the startup training should be supplemented with offsite professional training classes. We offer a variety of training opportunities that should be seriously considered by labs bringing in new equipment. Our recommendation is a pre-install training class followed by in depth advanced classes after a few months of operation. The investment in added training has a direct effect on the bottom line by reducing breakage and maintaining equipment up time. We offer Pre-Installation Operator Training at our state of the art training facility in Texas. This facility mimics the exact equipment the lab will be installing so the operators learn on the same equipment that they will be using in their own lab. Offsite training with the equipment manufacturer ensures 100 percent attention and maximized instruction. After a head start with the pre-install class, in a few months, all labs should participate in advanced, machine specific training at the manufacturer’s location. This combination of good, head start pre-training and supplemental advanced training will make your lab run at peak performance. Kevin Cross, Schneider Optical

There has been a growing need for quite some time by wholesale labs to show their in-house finishing capabilities to encompass handling the most high-end and complex frame design Rx jobs. Labs have realized that as reliable as they always were, the pool of hand crafting talent for such work is dwindling, in addition to being time-consuming and costly. Edging technology has evolved to such an extent that there are high-tech tabletop bench machines that marry the most eccentric levels of design and craftsmanship with consistent in-chamber customizable artistry, resulting in a “1st time fit” outcome. Labs that embrace this level of technology no longer have to send out complex jobs that have been sent to them, which allows them to market their full-scale edging and design finish abilities to ECP clients. Additionally, the profitability is significant. Furthermore, these labs are able to offer and manufacture unique products such as the Chemistrie magnetic sun lenses, which are easily processed on “design-centric” edgers, such as the Santinelli ME-1200 with its 5 axis 3D Drilling profile. A base curve (sun lens) to base curve (Rx) match is easily achieved. The Chemistrie product alone has added daily bottom line increases to labs such as Expert Optics in Shorewood, Illinois while expanding their specials and customizable edging profile across the board. “Specials” have become a requirement in today’s lab environment.
