Problems solved by technology

The finishing process for ultra-thin glass from 0.4mm to 2.5mm is generally: cutting, profiling, CNC (CNC machine tool) shape and drilling, cleaning, CNC chamfering, polishing, sweeping, ultrasonic cleaning However, due to the brittleness of the glass itself, the ultra-thin glass processing technology in the industry can only realize the finishing of a single piece of ultra-thin glass; a single piece of ultra-thin glass needs to be chamfered on a single side, an

Example Embodiment

[0030] Example one

[0031] For the simultaneous chamfering of the upper and lower sides of each piece of glass 5, a special CNC tool 6 is configured. The two chamfered bevels of the convex annular chamfered portion 5a form an acute angle; the special CNC tool 6 is such as Figure 5 Shown.

[0032] Such as figure 1 As shown, an original glass sheet with a thickness of 0.85 mm is selected, and the glass sheet can be flat glass or curved glass. Use a cutting machine to cut several single rectangular sheets according to the size and shape of the product design. The several single rectangular sheets can be directly purchased or customized in the market. Take six single sheets of glass 1 and stack them into a rectangular block. For glass, a spacer layer 2 with a thickness of 1 mm is arranged between every two adjacent single sheets of glass 1. The specific structure of the spacer layer 2 is: a spacer 2a with a thickness of 0.6 mm is placed on the spacer 2a. Both the surface and the low...

Example Embodiment

[0033] Example two

[0034] For the simultaneous chamfering of the upper and lower sides of multiple pieces of glass, a special CNC tool No. 7 is configured. The two chamfered bevels of the convex annular chamfering portion 5a form an obtuse angle; the special CNC tool No. 7 is like Image 6 Shown.

[0035] Such as image 3 As shown, the structure of this embodiment is basically the same as that of the first embodiment. The difference is that six pieces of single glass 1 are superimposed on each other to form a rectangular block of glass, and are arranged between each adjacent two pieces of single glass 1. The spacer layer 2 with a thickness of 1mm, 1mm, 0.5mm, 2mm, 1mm is directly formed by the adhesive 4, and every two adjacent single sheets of glass 1 are connected by the adhesive 4, such as Figure 4 As shown, according to the thickness of the single piece of glass 1 and the thickness of the adhesive 4 bonded between the single pieces of glass 1, a pair of special CNC tools 7 fo...

Example Embodiment

[0036] Example three

[0037] For the simultaneous chamfering of the upper sides of multiple pieces of glass, a special CNC tool No. 8 is configured. The convex annular chamfered portion 5a has only one chamfering bevel; the special CNC tool No. 8 is like Figure 7 Shown.

[0038] The structure of this embodiment is basically the same as that of the second embodiment. The difference is that a pair of each single glass is provided according to the thickness of the single glass 1 and the thickness of the adhesive 4 bonded between the single glass 1 1 The special CNC tool 3-8 for corner processing at the same time, the convex annular chamfering part 5a of this special CNC tool 3-8 is composed of a single chamfered surface, which is inclined to the upper side of the laminated upper and lower single glass 1 The corners are chamfered at the same time, and the lower side corners of the upper and lower single pieces of glass are not chamfered. After the special CNC tool 3 8 is designed, e...

Abstract

The invention provides an ultrathin glass corner machining method and a special computerized numerical control (CNC) cutter, and belongs to the technical field of glass machining. The method solves the problems that the conventional single ultrathin glass can only be subjected to single-piece and single-side chamfer machining and the machining efficiency is relatively low. The ultrathin glass corner machining method mainly comprises the following steps of: taking glass sheets, superposing the glass sheets, arranging a protective layer, curing a spacing layer, arranging the special CNC cutter for simultaneously machining corners of each glass sheet in superposed rectangular blocky glasses, and performing corner grinding on each glass sheet in the superposed rectangular block glasses by a CNC machining technology. By the method, polishing is not needed after machining, the glass machining efficiency is improved exponentially, shape and chamfer machining is performed on the superposed glass sheets, the surface of the single glass sheet is not easily scratched in the machining process, the product has good consistency, the qualification rate of the product is improved, and the machining efficiency is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of glass processing, and relates to an ultra-thin glass corner processing method and a special CNC cutter. Background technique [0002] Ultra-thin glass with a thickness of 0.4mm to 2.5mm is a good material commonly used in the electronic product window protection screen manufacturing industry due to its unique visual effect, protective performance and optical performance. The finishing process for ultra-thin glass from 0.4mm to 2.5mm is generally: cutting, profiling, CNC (CNC machine tool) shape and drilling, cleaning, CNC chamfering, polishing, sweeping, ultrasonic cleaning However, due to the brittleness of the glass itself, the ultra-thin glass processing technology in the industry can only realize the finishing of a single piece of ultra-thin glass; a single piece of ultra-thin glass needs to be chamfered on a single side, and then Then turn it over to perform chamfering on the other side, and the pro...
