Help Poly Grooved Rimless

**Mike Fretto** · 08-29-2005, 01:05 PM

Has anyone out there come up with a quick easy way to clean poly material out of the groove on a grooved rimless. We have a new mgr. in our dispensary that insists on poly for all grooved rimless to avoid chipping. He's killing us in the lab:hammer:

After grooving, take a knife and try to move the the unwanted poly residue into the groove, and re-groove the lens. It works for me, good luck.

Metal PD ruler always served me well. The same thing happens with Trivex.

You could fire the new manager. :D

Buy a new edger with grooving capabilities.Otherwise use the small screw driver tip (carefull don't slip).

I use the sharpest screwdriver I can find. Rout rout, blow out the loose bits, rout rout, etc.

If you have a buffer, the white rag wheel works great while giving a nice finished look to the edge. Just make sure you press lightly.

If not available, then metal pd works ok.

I second jubilee. Seems to give the edge a nicer appearance than just a pd stick. If there are any bits still left after buffing I remove them with my finger nail while running the lens under cold water. Light touch on thin lenses.

After edging, soak the lenses in hot water for about a minute. The groove waste will pull right off.

This way does look the best and only takes a few seconds.

Rub the lens against a carpet and the swarf comes right off. It is one of my little tricks I just recently picked up.

I have tried it. The edger guys say it works, but myself and my lab guy tried it and it didn't. Must be the type of carpet

You could also try removing the wet sponge from the grooving machine- I always found it easier to groove poly without the sponge present (usually you just end up with fine white powder).

Im intested to know how you get fine white powder from poly, Cr39 maybe but not poly. Im really interested in fine white powder:D it might make the new mgr easier to put up with:cheers:

When you groove it dry you get it

**edKENdance** · 08-30-2005, 12:25 PM

Grooving Poly wet. BAD!

**Mike Fretto** · 08-30-2005, 01:04 PM

I'm still not sure how you get a white powder from poly, all I have ever seen is a melted slag. Maybe the wheel in our groover is dull I dont know, it seems like its not a year old right now. We are cutting dry always have, it just seems like under the new policies we spend way too much time cleaning poly from the groove. :angry:

In growing through the different machinery and techniques the greatest to me is still the screwdriver blade technique. The only issue with this technique is if the lens that you are cleaning the groove out on is a thin poly then you run the chance of damaging the grooved wall, or if you slip with the blade "bye bye lens". I have had a little experience on a Santinelli edger out in the market that actually goes through the grooving process twice to remove any of the swarf build up inside of the groove. Grooving the lens dry is also highly recommended. This is one of the reasons why most auto grooving edgers do this process dry.

**Johns** · 08-30-2005, 07:07 PM

I put it in the hottest I can get the tap water. It only takes a minute.

**Jubilee** · 08-30-2005, 07:08 PM

Yes, Use dry. I don't know any one who grooves poly wet. Yet, 99% of the time, even with a brand new blade.. you will get swarf build up in the groove, and some strings as well.

Yes, but after you get a clean groove make sure you do a wet cycle once or twice.
