Can you use diamond drill to grind holes in the tempered glass after tempering?

Tempered glass should never be opened. Tempered glass is actually a kind of prestressed glass, in order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass, and the surface stress is first offset when the glass bears external force, so as to improve the bearing capacity and enhance the wind pressure resistance, cold and heat resistance, impact and so on; The strength of tempered glass is several times higher than that of ordinary glass, the flexural strength is 3 5 times that of ordinary glass, and the impact strength is 5 10 times that of ordinary glass. Its increased bearing capacity improves its fragile properties, and even if the tempered glass is broken, it is a small fragment without acute angles, and the damage to the human body is greatly reduced.

The resistance of tempered glass to quenching and heating is 2 to 3 times higher than that of ordinary glass, and it can generally withstand more than 150 temperature changes, which has obvious effects on preventing thermal explosion.

Therefore, 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.

The finished tempered glass can no longer be punched. This is because during the manufacturing process, the glass is treated by rapid cooling, and the internal structural stresses should be in a state of equilibrium. If it is punched, it destroys this state and it will break into small grains.

However, it can be annealed and then tempered. Tempered glass is first punched and then tempered, tempered can not be punched after tempering, tempered glass is made of ordinary glass, the strength of ordinary glass is greatly improved, and the deformation ability is reduced, so the destruction is all broken.

No, after the glass tempering, it is no longer possible to drill and grind holes, and the holes need to be pre-occupied before tempering.

It can't be punched, it can be edging, it can't be punched.

Can tempered glass be drilled? Hello, I am glad to answer for you<> pro tempered glass can be drilled.

1. Can tempered glass be perforated, many tempered glass are perforated and used in various occasions, especially in balconies or bathrooms, tempered glass is still relatively common. However, not all tempered glass can be punched, according to the following principles. 1. If the ratio of width and thickness of tempered glass is incorrect, it cannot be punched.

Normally, its width is greater than its thickness, and it needs to reach more than 8 times to be able to punch holes. 2. Before punching, you should also consider its thickness, if it is less than 12 mm, it is not possible to punch, because it will make the tempered glass very fragile. 3. If the hole is round, the diameter should be at least 2 mm larger than the thickness of the glass, and the hole should not be punched in the weak place.

Second, how to rent a reed to punch holes in the glass 1, we need to choose a drill bit, generally speaking, we must choose an alloy drill bit, and when punching holes, we have to water at the same time, to ensure that the drill bit will not smoke. Therefore, when punching holes, you need to prepare a bottle of mineral water, poke a few small holes in the lid, and you can use an electric drill to punch holes. 2. When punching, you first need to hold down the electric drill, and then open a half-moon-shaped groove on the glass at an inclined angle, and the action should be lighter.

3. After determining the position, we will start drilling, and put it vertically when drilling at the beginning, and then adjust the speed. This process involves constant watering to cool down, and the next step is to wait until the glass is drilled through. Hope mine can help you <>

Tempered glass belongs to safety glass.

Tempered glass is actually a kind of prestressed glass, in order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass, and the surface stress is first offset when the glass bears external force, so as to improve the bearing capacity and enhance the wind pressure resistance, cold and heat resistance, impact and so on;

The stress of the glass itself reaches an equilibrium, and once an external force (such as drilling, grinding) destroys the stress balance of the glass itself, the glass will "self-explode" - shatter into slag.

Traditionally, tempered glass just can't be drilled!

If you want to dig deeper, you can drill holes with lasers, but it is difficult and expensive, and it is not something that ordinary people can do.

The same is possible, use special tools and do a good job of cooling.
