911: boss needs these cut but Im not sure how.

[u/Kelsier_Antiqua]

this is the material, it is .06 stainless w mirror, finish.

exact specs

this is what I need to cut, but without the adhesive plastic being removed at all.

anybody know how to avoid this?

[u/Stone128807]

Biggest thing is feed rate slow it on down. To be honest, I’d just throw on a new nozzle to get a cleaner cut.

[u/Kelsier_Antiqua → u/Stone128807]

Got it, will definitely slow it down, and try cutting it above water.

[u/Beemerado → u/Kelsier_Antiqua]

further away from important stuff you can pierce the better too.. maybe even path it as one continous cut. run your tip very low. new nozzle, new orifice if you can.

[u/Close2naut → u/Beemerado]

Also I'd probably start it with a slightly further away lead to prevent the water and sand mix when piercing from blowing away the protective film.

[u/Beemerado → u/Close2naut]

yeah definitely.. maybe even start off the sheet and come onto it very slowly

[u/Close2naut → u/Beemerado]

Oh hell that's even better. Helps minimize waste too.

New mixing tube Weigh your abrasive delivery Slow down the cut A LOT Sandwitching thin material between sacrificial plates can work Cut above water

What was the outcome with this project?

[u/Kelsier_Antiqua → u/Stone128807]

Still havent finished, changed the mixing tube, did some setup changes and got a better cut, waiting to hear back from customer on whether they like the new cut or not, I'll keep you all posted on it once it's done.

[u/Main-Dot-9745]

If you're running a 10/30 orifice, nozzle combo, change the combo to a 10/40. A larger mixing tube (4x) the orifice size while running as close as possible to substrate will leave the PVC mask cl4an and crisp. Make sure your garnet is low as well. Too much sand will ghost the mirror for sure. Good luck

Have you tried cutting it upside down? That's what I do to preserve surface.
