Hey all,
as i look through the forums i cannot find where people would discuss machining ceramics. the closest i could find was the "glass, plastic ,stone" . am i overlooking a topic heading somewhere?
anyway, i am looking to find out what others who are machining materials like silicon carbide and saphire are using for tooling. i have machined fiber optic glass for years using diamond plated tooling bonded with nickel. the new shop im in machines Sic and they use resin bond wheels that wear out and dont hold their shape it is really a headache. i am looking for some specifics on what works well.

thanks
steve
