Vitreous bond silicon carbide wheel for grinding of silicon nitride L.M. Xua,1, Bin Shenb, Albert J. Shihb,* ... 400–6000 J/mm3, and follows an inverse relationship relative to the maximum uncut chip thickness as observed in other grinding studies. The SiC wheel wears fast in grinding Si 3N 4. The G-ratio varies from 2 to 12.
Hence the forces coming on the grit decrease.Grinding Wheel Speed If we increase the grinding speed the uncut chip thickness experienced by a grit decreases. . Thus increasing the wheel speed. The figure besides shows the three modifications on the existing designs for strengthening the wheel.
