It has been proven to be just as effective in polishing other hard substrates, such as silicon carbide, when a low roughness surface finish is required. The unique colloidal silica based formulation of Ultra-Sol S17 performs well in slurry recirculation systems due to the robustness of the particle, making it a perfect choice for all types of manufacturing environments.

Poco EDM Technical Manual

Use a silicon carbide resinoid bond work wheel and a regulating wheel surface speed of about 195 feet per minute. This will generally produce a finish of 64 µin Ra or better. Since more force can be used on high strength graphites, a 0.312" square rod can be through ground to a 0.250" round in a single pass.
