Intelligent, automatic blocking has come a long way– integrating seamlessly with advanced patternless edgers and aligning identically with traced data. Those systems are expensive though, and for those seeking a lesser option will find manual blocking still works perfectly well. The CE-1 is not however the best of manual blocking units and it’s various flaws and quirks leave us frustrated at times. Despite a cast-metal base weighing far too much, the top semi-transparent lens guide is made of thin plastic that seems to break eventually– especially when inexperienced users whip the lens clamp around without using the handle. Which brings us to our next point- the handle. A bizarre and ill-fitting black cap that doesn’t fit in the hand well and isn’t easy to hold onto. Over time the rotation of the lens clamp/lens guide seems to become stiffer– encouraging operators to not use the handle and instead whip the plastic cover to-and-from causing the plastic to eventually frail and break. The entire motion of the CE-1 feels overly mechanical without enough assist to aide the operator and if you’re cutting 500 lenses per day your hand might go limp. It almost feels like an old 1960’s American Muscle Car transmission. Further, the halogen illumination is sufficient- and the guides are easy to navigate. Plus, that heavy metal base doesn’t move on you when stamping’ it down 😉
OUR TAKE: A heavy, crude metal base with a under-designed lens clamp handle and flimsy plastic lens guide.
Which edger will this blocker work with?
Manual blockers will work with any optical lens edger that utilizes traditional ‘chuck-block’ procedures. Although this blocker is made by NIDEK/Santinelli, it is not necessarily restricted to those edgers of the same brand.
How much force is required to clamp down onto the lens?
Although manual blockers do require a manual/mechanical motion to clamp the lens, the force required should not limit any whom wish to use it. We have found that the actual blocking arm mechanism becomes stiffer over time.
What type bulb is used to produce the illumination?
The CE-1 requires a specific halogen bulb to produce the emitting of the semi-transparent blocking base.
