Abstract: This study introduces an ice fixed-abrasive polishing (IFAP) technology. Using silica solution IFAP pad and Al₂O₃ IFAP pad, orthogonal tests were performed on polishing high-definition display panel glass, respectively. The results show that the polishing efficiency and effect polished with silica solution IFAP pad are better than those polished with Al₂O₃ IFAP pad. The optimised silica solution IFAP parameters are: polishing pressure 0.1 MPa, polishing time 40 min, table velocity 80 r/min and the ratio of accelerator and slurry 1:10. Finally, the IFAP mechanism was studied and it is suggested that IFAP is a comprehensive effect of mechanical removal and microchemical reaction, combined with fixed abrasive polishing and free abrasive polishing.

Keywords: ice fixed-abrasive polishing; IFAP; high-definition display panel glass; material removal rate; MRR; surface roughness.
