Abstract
Improvements made in the manufacture of diamond wheels for the cutting of glass, especially optical glass, characterized, because, in the case of so-called fine wheels intended in particular for the carving of the bezel of glasses of glasses, the diamond powder of the the usual granulometry is loaded, or substantially loaded, in the area or zones of the grinding wheel that are responsible for the manufacture of the bevel, which, in this way, have a diamond dust content much greater than that of adjacent inactive zones and because for these fine wheels a binder composed of 45 to 65% (preferably 50%) of an alloy of copper, zinc and nickel and 35 to 55% (preferably 50%) of iron powder is used, because the mass of powder of the diamond and binder is subjected to a first cold pressing, then, in the same mold, to a sintering operation and, finally, to a second pressing operation at a much lower pressure than that used in the first pressing.
