Edging 1.74 and trivex

[chaoticneutral]

If I edge 1.74 or trivex once or twice a month, is that going to reduce the life or damage the roughing, finishing or polish wheel of my edger? We are using the Topcon ALE-5100 with whatever wheels came with it. Ive personally never heard of that happening, but the lab manager said absolutely not to do it.

Thanks

1.74 material is tough but should edge fine provided the edging cycle is set up properly..ie slow feed rate, plenty of coolant running during rough cycle etc. I would avoid Trivex as most "off the shelf" edgers are not set up for it. Labs that process large volumes of trivex will tell you this material will definitely put some wear and tear on your egder. Specialty roughing wheels are used for Trivex and poly machines. Check with your local lab and ask if they will edge your stock lenses for a minimal fee.

We had the misfortune of attempting to glaze a PNX (hoya Trivex) lens on an ordinary roughing wheel. We didn't manage to get to the finishing cycle, due to the noise/damage to the machine.

I would really suggest outsourcing your Trivex glazing, it's not worth the hassle.

Never had any issues with 1.74, I glaze at least 5 jobs a week with it in, and have for years.

A Trivex roughing wheel is under 300 bucks. Well worth the investment.

we use a 9000 series Santinelli that has a Trivex and high Index setting, but we still avoid in house edging for two main reasons:

1) Time, Trivex lenses take about 30-40 minutes per lens (very slow wheel rotation on this setting)
2) Odor Hi Index lenses stink up the lab all day long.

I have a 9000 LE and I put on a ruff cut with holes on it... i can edge with polish and bevel in under 5 min.
