Zusammenfassung:The invention belongs to the machining technical field of touch panels, and discloses a two-surface grinding method of a sapphire touch panel. The method is characterized in that a sapphire slice is put between upper and lower grinding plates for grinding; boron carbide grinding liquid is supplied between the upper and lower grinding plates; the pressure is controlled within 200-300 KG; and the rotating speed is controlled within 20-30 rpm/min. The sapphire touch panel, obtained according to the grinding process, has the one-time pass percentage higher than 95%, the surface roughness lower than 6 u and the TTV lower than 10 u.
