    Help! Edger leaving spots on lenses

    We are having a problem with our edger (CPE-4000) leaving spots on our lenses. They don't want to wipe off with normal cleaning techniques or alcohol but can be rubbed off with a fingernail.

    This is on a finished SV poly lens. The spots seems to have an almost oily consistency to them once you "scratch" them off with a fingernail. We have changed the water in the tank to no avail. Does anyone know what might cause this?

    Can you include picture of roughing wheel. When a poly lens is first cut @ roughing it mainly is ground into small granules. I'm thinking that if your roughing wheel is worn the granules are at an excessive (HOT) temp embedding into front of lens.

    Thanks for your input. I'm at a different office right now but will try to send a pic of the roughing wheel soon. Incidentally, I was talking about this problem with one of my reps who has a lot of experience in edging and he said the same thing. Might be time for a new wheel!
