The invention protects a processing method for a 3D net-free glass film. The method comprises the following steps: (S1) cutting a piece of glass into approximate shape according to the size of a to-be-processed 3D net-free glass film; (S2) for carving holes corresponding to the glass film in the cut glass plate by using a numerical control machine tool; (S3) coating sweeping powder onto the glass film cut by CNC, driving a vacuum chuck to press the glass plate onto the sweeping machine by utilizing a vacuum pump in a sweeping machine and performing sweeping operation; (S4) placing the swept glass into different cleaning agents for cleaning in turn; (S5) placing the cleaned glass into a hot briquetting mold for thermally pressing, thereby changing the edge of the glass to be an arc hook face; (S6) placing the thermally pressed glass into a high-temperature chemical toughening furnace and performing temperature sensing treatment at 650 DEG C; (S7) placing the toughened glass into an AF workshop and coating nanometer anti-fingerprint oil; (S8) adhering a layer of anti-explosion glue to the glass film surface; and (S9) adhering a double faced adhesive tape to the inner layer of the glass film, thereby acquiring the end product.
