Embodiment 1

[0027] A method for producing a mobile phone 3D glass cover, comprising the steps of:

[0028] (1) Engineering: According to the product drawing, issue an order;

[0029] (2) Cutting: choose 3D curved glass as the raw material, and carry out the processing allowance increase according to the product drawing. The method of processing allowance increase is to leave 0.1mm as the allowance on one side, and then input the product size data after the increase into the glass substrate Cutting machine for rough production;

[0030] (3) Jingdiao: Use the grinding wheel of Jingdiao machine to grind the rough glass, remove the margin, and use the drill to chamfer and drill the glass raw material, and use the fine grinding wheel to finish the shape and camera hole, with a processing accuracy of 0.01 mm;

[0031] (4) Grinding and polishing: add polishing powder to the 3D glass grinding machine, grind the glass raw material to the thickness required in the drawing, and then polish it to a...

Embodiment 2

[0046] Control the temperature in the heating furnace to 750°C and the heating time to 40min;

[0047] The tempering treatment time is 6 hours; the tempered glass product is subjected to a drop ball test to ensure that the glass product can withstand the impact of a 130g steel ball falling from 65cm;

[0048] All the other are with embodiment 1.

Embodiment 3

[0050] Control the temperature in the heating furnace to 720°C, and the heating time is 30 minutes;

[0051] The tempering treatment time is 5 hours; the tempered glass product is subjected to a drop ball test to ensure that the glass product can withstand the impact of a 100g steel ball falling from 65cm;

[0052] All the other are with embodiment 1.
