Tempered glass cannot be cut by laser. The tempered glass can no longer be cut and processed, and the glass can only be processed to the required shape before tempering, and then tempered.
Tempered glass is a safety glass, tempered glass is actually a kind of prestressed glass, in order to improve the strength of the glass, usually use chemical or physical methods, the formation of compressive stress on the surface of the glass, the glass to withstand external forces first offset the surface stress, thereby improving the bearing capacity, enhance the glass itself resistance to wind pressure, cold and heat, impact and so on.
Tempered glass features:
Step 1: Security
When the glass is damaged by external forces, the fragments will become obtuse small particles similar to honeycomb, which is not easy to cause serious harm to the human body.
2. Height
The impact strength of tempered glass of the same thickness is 3 to 5 times that of ordinary glass, and the bending strength is 3 to 5 times that of ordinary glass.
3. Thermal stability
Tempered glass has good thermal stability, can withstand the temperature difference is 3 times that of ordinary glass, can withstand the temperature difference of 300℃.
Ordinary glass can be cut by laser, the advantages of ordinary glass using laser glass:
First, all laser cutting methods use non-contact processing technology, which greatly avoids the problem of fine cracks and debris.
Second, the residual stress left in the glass by the laser cutting method is very small (the residual stress of different cutting methods is different), so the strength of the cutting edge is higher. This is very important, if the residual stress is too large, then even in the center of the glass plate, it often causes the edge of the glass to break. Therefore, compared with the glass cut by mechanical method, the force that laser cut glass can withstand is 1-2 times larger.
We should remember that tempered glass can not be cut with laser, but ordinary glass can be cut with laser, if you want to cut the glass, you can cut it before tempering.
