dry grinding m c - batidetect.fr

By using water spray during grinding, the calculated c cr of dry ground specimens was reduced by about 30%, indicating lower stresses during wet grinding. In comparison with Si 3 N ceramics, a further reduction in c cr can be expected by using a finer diamond burr [15]. Sandblasting followed by dry grinding appears to be at least as detrimental ...
