Glass machining

kzt · Jul 11, 2019

What is the optimal way to create a chamfer or radius on the edge of a fused quartz (glass) part - ie. are there special machines that just do this? Tried using a CNC machine but not only did the edge have chipping all around but it also took a long time (8000rpm and used diamond tooling). Not sure I hit the right sfm...

Appreciate any helpful responses!

Thank you!

Grinding, typically wet grinding. Slow feeds, lots of coolant.

I've seen 5-axis waterjet do this with abrasive particles. Surface finish is semi-rough like sandpaper though.

You use a diamond abrasive wheel and lots of coolant. Step in slowly 10ths at a time. Works fine. Grinding as btrue sez.
