The invention provides a nano silica abrasive polishing liquid for processing glass ceramics, which comprises abrasive I, abrasive II, surfactant, pH adjuster and deionized water; the weight percentage of each component is: abrasive I is 10% to 40%, Abrasive II is 5% to 20%, surfactant is 0.01% to 0.6%, pH adjuster is 1% to 6%, and deionized water is the balance; The pH value is 10 to 12; it can be used for surface polishing of glass-ceramics, effectively reducing the surface scratch after polishing of glass-ceramics, reducing the surface roughness after polishing of glass-ceramics, and meeting the needs of manufacturing computer hard disk substrates. And the polishing rate is fast, the polishing liquid does not corrode the equipment, and the safety performance is high.
