Can tempered glass be cut
Laser cutting was initially tested on thin metal. recently, this same method has been used to cut glass using special devices. There are two types of laser cutting. The first is an original technology called thermal evaporation laser cutting. This process is currently practically not used, since it is the slowest and consumes a large amount of energy. The method itself consists in evaporating the glass to the end. The main disadvantage of this option is the presence of residual stress in the material due to heating, which can lead to breakage of the product along the edges of the cut.
The second method, which is currently used, has been developed as a result of the improvement of thermal evaporation. It was found that it is not at all necessary to completely vaporize the glass with a laser; low thermal conductivity and thermal resistance allow the use of the thermal cleavage method. The principle of this method is to discretely heat the glass along the entire cut line. This is followed by a sharp cooling, and in this area a tensile stress is formed, breaking the glass clearly along the mowing line.
This method is faster and less energy intensive, so it is now actively used and gaining momentum.
Laser cutting has several advantages:
- high-quality cut with a flawless edge;
- curly cutting is simplified;
- it is possible to cut glass with a large thickness;
- no mechanical impact is exerted on the product;
- easy regulation and control of the cutting process.
The glass laser cutting process is currently under development. Therefore, like all new technologies, this method has its drawbacks:
- Low-emission material (reflective infrared radiation) is not suitable for laser processing;
- expensive machines requiring careful use;
- low processing speed. from 5 to 10 m / min.

Waterjet cutting was made possible in the 1980s by the use of powerful hydraulic pumps that allowed the fine, sharpened granules of shredded materials to be mixed with water. The technology is designed for cutting a wider range of materials. Glass is very suitable for this method, which leaves a matte edge that is easy to polish.
- excellent edge quality, which makes sanding unnecessary;
- no chemical and thermal effects on the material, slight mechanical stress, no cracks;
- the ability to cut very thick and laminated glass.
Despite the advantages, there are also disadvantages:
- very low cutting speed (0.5-1.5 m / min) depending on glass and equipment;
- high costs of equipment operation;
- the need to prepare a large amount of water.
Before starting cutting any kind of glass, first of all, you need to check the health of the glass cutter and its sharpening. It is necessary to try to cut out an unnecessary piece of the sheet. A working glass cutter moves without effort and squeak, the cut line is thin and continuous. All other results will indicate that the cutting element is defective or that there was a mistake in cutting technique.
It is also worth choosing a flat support with dimensions larger than the dimensions of the processed sheet. Any straight surface will do. For safety, it is worth laying a thick cloth on it. Glass marking tools are a bright marker, iron ruler, tape measure.
For high-quality cutting, it is necessary to follow the technology and sequence of operations.
- Apply the start and end points of the cut on the surface.
- The glass cutter is at the top and has a ruler attached to it.
- Cutting is performed smoothly from top to bottom, with constant force and in one direction. It is not necessary to carry out the glass cutter several times in one place. Glass may crack.
- Break off a piece by aligning the cut line with the edge of the table. Create a crack by gently tapping the cut with a glass cutter and then chipping in one sharp motion.
- If the chip is uneven, you can correct it with pliers or use the special cutouts in the handle of the glass cutter. To avoid cracks, the cut line must be moistened with turpentine.
- At the final stage, sand the cutting line with sandpaper, a velvet file or a sharpening stone.
Hand cutting exists and is quite common, but it is usually only used for small repairs, otherwise it is impractical. The oldest and most common method of processing and cutting glass is the mechanical method. This is currently the most suitable processing method. This method involves the use of special wedge-shaped cutting rollers, made mainly of tungsten.
Cutting in this way involves two operations. First, the roller makes a groove (risk) on the glass of the desired trajectory, after which an attempt is made to break it.
Despite the outdated mechanical cutting technology, it still has significant advantages:
- the highest cutting speed. up to 120 m / min;
- low cost of equipment and ease of maintenance;
- workpieces can be of various sizes and shapes.
The most common disadvantages of mechanical cutting are:
- chips and roughness of the cut due to mechanical defects in the material;
- the need for subsequent processing and finishing of the cut edge;
- when cutting it is necessary to use special fluids.
Glass cutting is the most important step in the processing process. As a result, the product acquires the specified dimensions and shapes, as well as the possibility of artistic finishing that improves its appearance. These actions, depending on the desired result, can be performed in various ways and methods on specialized machines.
How and what can you cut glass?
- Basic ways
- How to cut glass at home?
- detailed instructions
No house can do without glass, and, therefore, the question of cutting it arises in almost every renovation. There are many ways to solve this problem.
How to cut glass at home?
Before cutting glass at home, you first need to determine the tool that is applicable for this method. In most cases, a glass cutter is used to cut glass. There are the following types of glass cutters:
This process can also be done with a soldering iron, angle grinder or circular saw, nichrome wire, and even regular scissors.
- Soldering iron. First of all, risks are applied on both sides of the mowing line with a rasp. Then the entire line of the cut is heated using a well-heated soldering iron. Due to the temperature difference on the surface, the glass breaks, after which it remains only to gently break it off.
- angle grinder or circular saw. To cut off the glass of an angle grinder, you must use a diamond disc. First, use a diamond disc to make a small groove along the mowing line of the cut. In the process of work, make sure that the glass surface does not get very hot. To do this, water the surface with ordinary water. The tool used in this method must be in good working order and free from any defects. Otherwise, the glass will just shatter.
When working with an angle grinder, it is necessary to use personal protective equipment for the respiratory and visual organs.
- Use of heating and cooling. Place the thread impregnated with a flammable substance along the cut line and set it on fire. After the thread has completely burned out, cool the surface sharply with cold water. From such a temperature difference, the glass will collapse along the cut mowing line. Another option is to heat the material using a nichrome wire connected to an electric current. This method does not use water for cooling. The temperature difference between the filament and the glass is enough to chip in the intended place.
- Scissors. Thin glass of small thickness is cut with simple scissors, if this is done by dipping the scissors and glass under hot water. It is similar to cutting thick cardboard with a knife.
We cut tempered glass. just annealing it!
- To drill round holes in glass, use drills for ceramic surfaces, as well as diamond core bits of various diameters.

What is wired glass at work?
How to cut wired glass? This is quite difficult, because the glass bends back along the mowing line of the notch, but continues to adhere to the metal mesh. In this case, the piece must be bent all the way and part of the holding wire must be bitten off with nippers. The disadvantage is that it is difficult to remove small pieces and fit the canvas to size.
Wired glass cutting is best done on automatic carving tables that provide high speed and precision. When cutting, it is advisable to take into account the direction of the mesh cells.
Reinforced glass 4 mm is most often used for decorating loggias, balconies and terraces; it is inserted into joinery or aluminum profiles for cold glazing. Special care for such material is not required, except for the removal of dust and dirt. But due to its fragility and low strength, it must be protected from mechanical damage, after damage the sheet will have to be replaced.
The aesthetic properties are excellent, the room can be saturated with color and protected from fire. You can cut
the sheet according to any template, and using it in public buildings will save a lot of lives. It is a durable and reliable building material.
How to properly cut glass with a diamond glass cutter
It needs to be held slightly tilted to the right to the plane of the glass. Its cutting tip does not move, so the furrow is carried out by one of its edges. The diamond trace is thin, almost imperceptible. However, this does not prevent them from being used for cutting glass of considerable thickness.
Diamond glass cutter
Diamond glass cutter is able to cut glass up to 10 millimeters thick
The diamond glass cutter can be safely called the “flagship” among such tools. As a cutter in such glass cutters, diamond is used. the most durable material in the world. Thanks to this, the diamond glass cutter is able to cut glass with a thickness of up to 10 millimeters, while making the most even cut, practically free of chips and requiring minimal processing. The only drawback of a diamond glass cutter can be considered only its relatively high cost, even in those cases when not natural, but artificial diamond is used as a cutter.
Working with a diamond (as well as with any other glass cutter) requires certain skills.
The first step is to prepare the surface on which the glass will be cut. For this purpose, an ordinary table is perfect, which must first be covered with something soft (for example, carpet or linoleum). Prepared glass is laid on the surface.
Before the main cutting, it is recommended to check the glass cutter on an unnecessary piece of glass. To do this, take the tool with your thumb and forefinger and slide the line over the glass with slightly more pressure than when writing with a ballpoint pen or pencil. If the result is a thin white line, the glass cutter is ready to work and you are doing everything correctly, If the line is thick and filled with small glass chips, try changing the angle of inclination of the cutter.
The process of cutting glass with a diamond glass cutter itself is as follows. Using a ruler and a square, the necessary markings are applied to the glass. After that, along the side of the same ruler or any even bar, they carry out a glass cutter with a medium pressure. The white line remaining from the cutter is aligned with the edge of the table and lightly pressed against the hanging edge of the glass. If you did everything correctly, the glass will break off quite easily exactly along the mowing line of the cut.
When working with thick (thicker than 2 millimeters) glass, before breaking, it is recommended to slightly “tap” the cut line with a hammer.
If the glass does not break, do not try to re-cut in the same place as the previous one. Better shift the markup a little and repeat the whole operation.
In order to better understand the principle of working with a diamond glass cutter, we recommend that you look at the following
How to cut glass with a glass cutter correctly with your own hands at home
How pressure on the roller affects the cut
The penetration depth of the scratch into the glass depends on the applied cutting force. When choosing a sharper cutter for thin materials, it should be borne in mind that it is dangerous to create a high load on them, because you can simply crush the material.
To facilitate cutting the workpiece, when performing such work, they always monitor the cleanliness of the glass and treat its surface with special liquids, which:
- lubricate the roller;
- provide a hydraulic cushion;
- reduce the effect of the Rebinder effect, reducing the strength of the outer surface;
- wedge material.
At home, for these purposes, it is quite possible to do with kerosene. It is convenient to apply it by hand with a piece of cloth or use a glass cutter of a special design.
A couple of tips for purchasing
- Before buying any kind of glass cutter, it is best to ask the seller to check the tool.
- In the event that the tool suits you, then you can buy it, but buy the one that was shown to you.
It is not recommended to buy an untested tool, since in most cases the cutting edge is defective.
Plexiglas is a hard transparent plastic based on synthetic resins. You don’t need any special tools to cut such glass. At home, you can easily cut it with a metal saw, cutter and other tools. And if the thickness of the glass is not more than 2 mm, then the work can be done with an ordinary clerical knife.
Cutting tempered glass
Cutting tempered glass in the standard mode is impossible, which is due to the change in the properties and structure of the material after additional hardening. Cutting with the usual method will break the material into many tiny fragments.
Contrary to these restrictions, cutting is quite possible. It is important to know the technological process and have certain skills in order to achieve the desired result.
Cutting and drilling tempered glass at home
For cutting tempered glass, it is permissible to use only one tool. a laser. In the absence of this unit, at home you need to use another technique, which implies preliminary annealing.
Performing work requires the following components:
- tempered glass;
- water at room temperature;
- Temperature regulator;
- tempered glass;
- grinding stone;
- glass cutter;
- square and marker;
- wooden rod.
After annealing, the glass is cooled to values not lower than the temperature during deformation. The procedure takes a lot of time, since it is required at an indicator of 400-427 0 С to reach room mode.
A square and a marker mark the mowing line along which the material will be cut. The work is carried out with a glass cutter. The marked trajectory is only allowed to be traversed once.
To simplify the process, a wooden rod is placed under the cut contour, after which a sharp pressure movement is made with effort. At the exit, two even pieces of glass are obtained. For greater safety, the edges of the fracture are carefully sanded.
How to bend tempered glass
Bending of tempered glass is carried out with simultaneous hardening and is carried out on a mowing line for tempering curved glass. After establishing the radius, the glass heats up to a plastic state and undergoes deformation. The process guarantees high accuracy and repeatability of the specified radii.
How to cut and cut tempered glass
Tempered glass is a fairly strong and resistant material.
Despite this, there are still several options with which it can be cut, including:
- Waterjet cutting. It is supposed to supply water to a special chamber under high pressure. In this case, the combination of the water mass and the abrasive powder occurs, after which the water hits the surface to be treated through a thin nozzle. The speed of water supply is equal to 3 speeds of sound, therefore it will cut any surface, including tempered glass.
- Abrasive wheel cutting. The glass is mounted on a movable table, after which a structure similar to an angle grinder equipped with an abrasive wheel is lowered onto it. Watering the cutting area with lubricating-cooling liquid with a low feed of the table relative to the circle, the work will bring the required result.
- Vacation cutting. The glass is heated to temperature values at which the tempering effect is removed. The material is cut and, if necessary, hardened again.
In theory, such an operation is quite feasible. Experts still advise buying ordinary glass, cutting it into the necessary parts, and only then. temper.
How to drill tempered glass
Drilling tempered glass is impossible, since when you try it will split into many small elements, despite the high strength values. If, nevertheless, such a need arises, it is worth contacting special workshops that will help solve the issue using special technologies.
Tempered glass cutting technologies at the exhibition
At the thematic exhibition Mir Stekla, the leading techniques and technologies for the production and processing of regular and tempered glass are presented. Samples of the offered products are placed on the stands. The exhibition is attended by major manufacturers and suppliers of equipment for glass processing, including cutting of tempered glass.
