This polishing process was processed by chamfering, polishing (wetting) wet processing by the grinding (Grinding) processing method using a mimic cam.
However, the cross section of the glass treated by dry and wet processing such as grinding or polishing still suffers from low strength in terms of strength and weak brittleness.
In addition, the mechanical polishing method such as the grinding processing method or the polishing wet processing method has a problem that the production efficiency is also very low because the equipment is complicated and expensive, and only a single layer operation is possible according to the miniaturization of the glass.
In addition, even after dry and wet processing such as grinding and polishing, which is a cross-sectional process, fine cracks, chipping, burrs, and the like of the processed surface are present.
Therefore, even if the cross section of the cut glass according to the size by the mechanical processing method has a limitation in terms of strength or brittleness, a new method of cutting surface treatment should be sought.

Here, the chemical reaction resin may be selected from any one of UV curable resin, visible light curable resin or thermosetting resin.
Here, the coating of the chemically reactive resin may be coated by any one of a roller coating, a brush coating, a nozzle injection coating, a spray coating method or a dipping method.
At the time of coating and curing the chemically reactive resin, it is preferable to form a barrier film on the upper and lower surfaces of the cut glass to be coated, thereby coating and curing.
When coating and curing the chemically reactive resin, the glass to be coated may be arranged up and down to simultaneously coat and cure a plurality of glasses in a multi-type manner.
According to the configuration of the present invention described above, the strength and brittleness of the cut surface of the glass is excellent, the processing time of the glass cut surface is fast, simple, can simplify the equipment, increase the amount of glass per hour to increase the production efficiency It is possible to propose a new method for processing the glass cut surface to increase the.

Such chemically reactive resins include UV curable resins, visible light curable resins and thermosetting resins.
UV curable resin has vinyl group or unsaturated group component such as C = C in the resin molecular structure. When it receives light (ultraviolet), photoinitiator is activated and it crosslinks and polymerizes through initiation reaction of free radicals. Means a resin formed.
The visible ray cured resin is a resin cured by irradiation of visible rays, for example, one or more of an acrylic component, a polyene component, and a polythiol component can be used. As a reactor, an acrylic group is generally more reactive than methacryl. Since it is known that an acryl group is introduce | transduced in contact with air and a fast hardening property, it is more preferable to introduce a polyfunctional group, since a polyfunctional group shows faster hardenability than a monofunctional group.
The thermosetting resin means a resin that is cured by heat.
In addition, as the thermosetting resin used as an organic adhesive in addition to the chemically reactive resin, urea resin, melamine resin, phenol resin, unsaturated polyester resin, epoxy resin, resorcinol resin and the like can be used.
Curing source for curing resin can be UV lamp, visible light lamp and IR lamp as a source. Curing glass is coated with liquid resin and dried at temperature (heat) of 20 ℃ ~ 100 ℃ or UV irradiation. The cut surface of the glass may be treated by curing the liquid resin using an apparatus or a visible light irradiation apparatus.
