Re: [CAD_CAM_EDM_DRO] Re: cutting mirror

Hello George and Jon,
in the windshield facility where I have to do repair work they use wet
belt sanders or wet diamond wheels (at low depth and well balanced)
for this type of work. The grinding wheel has to be used with very
much care for not to shatter the mirror.
Hope this is useful
