Usually vitrified wheels are used at speeds less than 6,500 surface feet per minute. At higher speeds, the vitrified bond may break. Organic bond wheels are generally the choice between 6,500 and 9,500 surface feet per minute. Working at higher speeds usually requires specially designed wheels for high speed grinding.
A: Grinding refers to the removal of large amounts of material from the surface of the stone. Grinding is used to remove deep scratches and staining as well as lippage (uneven surface) thereby smoothing out the surface of the area making it uniform. Honing is the smoothing of the stone, not as aggressive as grinding and removes very little ...
