The effects of mass fraction of abrasive,pH value,flow rate of polishing slurry,rotate speed,surfactant types and mass fraction of NH_4 F on the material removal rate and the surface roughness of the ceramic glass substrate were investigated by CeO_2 slurry.The surface roughness of the ceramic glass substrates after being polished was characterized by atomic force microscope.Results show that the material removal rate(MRR)could reach 180.91nm/min and the surface roughness could reach 0.72 nm under the follo...
