DIAMOND WHEELS WITH ORGANIC BINDER FOR PRE-GRINDING HIGH-GRADE AND ART GLASS

It is shown that the organic binder MV1 with diamond powder with grain size 90/70 mu m and concentration 150% is best for preliminary diamond grinding of high-grand and art glass, followed by chemical polishing. MV1 organic binder for wheels with diamond grinding powder with grain size 90/75 mu m and concentration 150% used instead of M2-01 binder with grain size of the diamond powder 53/45 mu m and concentration 50% made it possible to increase the productivity of preliminary diamond grinding of high-grade and art glass followed by chemical polishing by 20 - 25% and to increase the wheel longevity by a factor of 1.8 - 2.3 with the same wheel production cost and worked-surface roughness.
