Glass etching with cnc

Can you etch glass with the cnc machine and if so what would you use as a cutter

[WillAdams (William Adams (Carbide 3D))]

Some folks have used a regular carbide endmill (this has safety implications and is best done with the glass submerged):

Cutting Glass With CNC

Machining Glass

Hello all, I need to accurately cut 1.12mm thick glass sheets for a scale model. Mostly precisely placed holes and outside dimensions that include a curve. I found this: http://benkrasnow.blogspot.com/2011/08/cnc-milling-glass-plates-and-mirrors.html Questions (that I can think of): What is the best coolant to use? Can I use water as a coolant? If I submerge the glass in a tank of coolant (to contain the mess and particles), is that okay? Are there any nuances to diamond burrs I need to …

Note that the debris from cutting must be discarded in a safe fashion and not poured into a municipal water system (the tiny shards will shred the filters).

Otherwise, a diamond drag bit is the usual choice:

Interesting… I would have thought setting “Min Depth” and “Max Depth” to the same value would have yielded a single consistent depth per pass. Is that not the case?

Get a spring loaded diamond drag bit, available on E-Bay and Amazon. They come with different tip angle that provide etching of slightly different width. The difference may be subtle, I don’t have enough experience to really tell the difference.
