I make a lot of vacuum fixtures to keep thin and delicate parts in spec while machining and have a part that I think would be best made using UV glue.

Does anyone here have any experience using it as part of a set up?

The part in question would be glued to a fixture to keep it supported then the part itself would be held in a soft jaw setup.

Thanks
 
I have used the uv curing adhesive made by Dymax with some success however I was not overly impressed. It lacks the strength I was hoping for for one thing. The only thing I found useful was that you can hold something in position and then zap it.
 
How did you break the bond after machining? I can't really pry on the part without damaging it.

Am I making it up but I recall hearing about an adhesive that is hardened with one light and loosened by another? Anyone hear of that or was it a fever dream I had?
 
Unfortunately I have no personal experience with UV cring adhesives. However, Henkel, the manufacturesr of Loctite, has a ton of experience. I am confident a call to them would answer your questions as authoritatively as is possible.

This is a great resource. I'll give them a call.


Thanks
 
Used it a bunch, but on stuff that it was ok to get hot, so we just put the whole thing in the furnace when we were done. Made a plywood curing box. Be careful - the UV lamps can give you a sunburn very quick!
 
why the UV cure system? are parts or fixtures transparent so the UV can actually get to and activate the glue?

what are the materials? wouldn't cyanoacrylate work better (if the fixture/part materials are compatible)? a little bit of heat to get it to release the part after machining and easy clean up as well
 
Call Tom @(219)671.1998 He is a Loctite/Henkel UV Adhesives Specialist and will tell you all about their products and advice if it is a good fit for your application.
 
No exp with UV glues, but we make parts out of .002" brass shim that we use regular 3m type spray adhesive to hold. What we do is skim our 'fixture' plate so it is nice and flat, clean up with acetone/air, spray the adhesive on, wait a minute then attach the piece of shim and use a 1-1.25" pin to roll it flat and get it to glue down. Works good for our purposes. Keep in mind though we are using .006"-.010" endmills so there isn"t anything much of tool pressure.... A quick shot of acetone and a razor blade get the part off the plate.
 
Btw, have you considered wax? We had a great success with it holding delicate glass parts during the machining operations requiring lots of coolant.
3M adhesive is also good but it tends to get softened and partially dissolved by our coolant.
 
Your dentist uses UV cured fillings. I have a few. I had a few scratches in my granite counter top that I made to disappear with UV clear. 5 years ago and still cannot find them.

I've got crowns that are held on with UV cured adhesive. I'm pretty sure there is a way to unglue them too as I've had some work done on a few of them and they were removed and replaced.
 
Don't forget about shellac resin, it's been used for millennia as a fixturing adhesive. And there's woods metal, it has a low enough melting temperature to be usable as long as you control the part temperature.
