Choosing the proper CBN grit size | Cutting Tool Engineering

Apr 01, 2013 · As grinding proceeds, the power drops slowly as the grits sharpen and fall out, and surface finish gradually worsens. Eventually, the finish approaches the roughness limit and you have to dress. If you choose a grit size that's too large, the surface finish after break-in is too rough. Grinder operators cope with this by dressing the wheel to .
