Embodiment 1

[0040] Such as Figure 1-8 A gradual thinning process for foldable glass includes the following steps:

[0041] Step 1. Use a cutting machine to cut the raw material (T≥0.2mm, specifically choose 0.2mm) into blanks (for example, product size length 165*width 135mm, blank size length 165.5*width 135.5mm), cutting parameters: diamond cutter wheel The angle is 120 degrees, the cutting speed is 600±100mm / s, the cutting pressure is 4±1%, and the cutting depth is 0.05±0.02mm.

[0042] Step 2. Use the CNC machining center to finish the blank (size, shape structure, gradient area structure, etc.), install the blank to the special fixture of the CNC machining center, turn on the spindle speed, turn on the cooling lubricant, and start processing. Grinding wheel A is processed in the gradient area, the feed speed is 600mm / min, the spindle speed is 28000r / min, the diameter of the grinding wheel Sand grain 500#; the product shape is finished at the grinding wheel B, the feed speed is 80...

[0051] Such as Figure 1-8 A gradual thinning process for foldable glass includes the following steps:

[0052] Step 1. Cut the raw material (T≥0.2mm, specifically choose 0.25mm) into a blank with a cutting machine (for example, the product size is 165*width 135mm, and the blank size is 165.5*width 135.5mm). Cutting parameters: diamond cutter wheel The angle is 120 degrees, the cutting speed is 600±100mm / s, the cutting pressure is 4±1%, and the cutting depth is 0.05±0.02mm.

[0053] Step 2. Use the CNC machining center to finish the blank (size, shape structure, gradient area structure, etc.), install the blank to the special fixture of the CNC machining center, turn on the spindle speed, turn on the cooling lubricant, and start processing. Grinding wheel A is processed in the gradient area, the feed speed is 600mm / min, the spindle speed is 28000r / min, the diameter of the grinding wheel Sand grain 500#; the product shape is finished at the grinding wheel B, the feed speed i...

[0062] Such as Figure 1-8 A gradual thinning process for foldable glass includes the following steps:

[0063] Step 1. Use a cutting machine to cut the raw material (T≥0.2mm, specifically choose 0.3mm) into blanks (for example, product size length 165*width 135mm, blank size length 165.5*width 135.5mm), cutting parameters: diamond cutter wheel 1200, cutting speed 600±100mm / s, cutting pressure 4±1%, cutting depth 0.05±0.02mm.

[0064] Step 2. Use the CNC machining center to finish the blank (size, shape structure, gradient area structure, etc.), install the blank to the special fixture of the CNC machining center, turn on the spindle speed, turn on the cooling lubricant, and start processing. Grinding wheel A is processed in the gradient area, the feed speed is 600mm / min, the spindle speed is 28000r / min, the diameter of the grinding wheel Sand grain 500#; the product shape is finished at the grinding wheel B, the feed speed is 800mm / min, the spindle speed is 38000r / min, the...

Abstract

The invention discloses a gradient thinning process for foldable glass. The gradient thinning process comprises the following steps that a raw material is cut into a blank; a numerical control machining center is used for finish machining; a polishing machine is used for polishing a finish-machined gradual change area face; a polished product is cleaned under an ultrasonic condition; acid-proof ink is printed on the single face of the polished face for protection; single-face chemical thinning and acid-proof ink removing are conducted on the product printed with the acid-proof ink; and the product on which the acid-proof ink is removed is cleaned and detected under an ultrasonic condition. According to the process disclosed by the invention, chemical thinning is carried out after mechanical pre-processing, so the problems that the step connection of a glass product is not smooth, and folding strength and toughness are damaged are solved.

Description

technical field [0001] The invention relates to the technical field of foldable glass, in particular to a gradual thinning process of foldable glass. Background technique [0002] Since foldable electronic consumer products have been commercially available, the exploration of foldable product structures has continued to deepen. At present, the more mature material of foldable cover plate is colorless transparent polyimide film (CPI), but there are serious crease problems. The rigidity of the glass cover can well improve such problems. And when the thickness of the glass is less than 0.1mm, that is ultra-thin glass, it has excellent foldability and high hardness scratch resistance, and becomes an important material in the field of foldable flexible cover after CPI film material. [0003] The substrate material (foldable glass Ultra-Thin Glass referred to as UTG), one of the key structures of the foldable flexible screen, is particularly important. Fitting, so the strength,...
