Finishing and superfinishing wheels are abrasive wheels used for special applications in centerless grinding. A correct combination of bond type and abrasive grit size helps to obtain very low roughness parameters at the end of the superfinishing operation. Obtainable surface roughness parameters: Ra = 0,06-0,1 µm, Rt < 1,0 µm.
