Beschreibung
Zusammenfassung:	The invention relates to a method and a device for repairing scratches on strengthened glass surface. The method comprises the following steps: (1) polishing the substrate surface with abrasive without the presence of polishing liquid, wherein the polishing treatment is carried out under the condition that the contact pressure between the abrasive and the substrate surface is 0.8-4N and the substrate surface temperature is less than 40°C; (2) The substrate surface after step (1) is processed with mirror treatment with abrasive without the presence of polishing liquid, wherein the polishing is carried out under a pressure of 0.4-2N contact pressure between the abrasive and the substrate, and a temperature of the substrate surface less than 25°C. The method and equipment can effectively remove or reduce the scratch on the strengthened glass surface of electronic products without dismantling the machine, restore the smoothness of the glass, and achieve the mirror effect.
