I work in a laser optics laboratory and we machine and shape glass exclusively.
If you have a cnc machine to cut the template why not use it to cut the glass? what we do is use wax to affix the glass to another piece of glass then to a piece of metal (aluminum, steel) then you can use clamps to hold the metal so you don't have to clamp directly onto the glass.the reason we wax the glass to another piece of glass is so you can cut into the second piece of glass all the through the top piece of glass. the drills we use are a sintered metal diamond mix. the feed rates are pretty slow (1/2 IPM or less) and we use a synthetic oil/water mix for coolant. |
