I’ve been cutting glass plates and mirrors with my CNC milling machine machine for years. In this video, I describe a few tips and the general technique that I use.
Clamping the glass plate to the table is the critical part of the process, and so I built a jig that allows the glass to be held laterally with shims, but does not require a high clamping force, which would crack the glass.
Cutting parameters:
.085″ dia diamond burr
3000 RPM
1-3 inches per minute feed
Cut depth .130″ (full material thickness)
Flood coolant with soluble oil cutting fluid
