To the edge of the glass turned out as even as possible, it is necessary to cut it properly. When cutting, hold the glass cutter vertically in relation to the glass, pressing it from above with your index finger. Use a glass cutter to run along a flat rail or insulating tape. Start cutting from the far end. Run the glass cutter toward you, evenly pressing on the surface. Spend only once. Before breaking the glass, place a match at the end of the cut. Tap the notch gently with a hammer, so it will turn into a smooth break.

After cutting, proceed to processing the edges of the glass. After cutting, the glass has protrusions and notches, as well as sharp edges. It is better to process the edge of the glass on special machines, but at home this method cannot be applied.

Take a file, for velvet is suitable for thin glass, for thick it is better to take personal. Place a small jar of kerosene or turpentine near it to constantly wet the file. You can also use a solution of camphor in turpentine in the ratio of 1 to 10. Of the grinding bars, use emery and carborundum; By the way, the latter can not be wetted.

Begin to cut the glass along its edge. Work very carefully, especially with thin material. To obtain a straight edge, move the glass back and forth along the surface of the bar. Constantly wet the instrument in the prepared composition.

For this work, use old emery blocks and old files, as during the grinding process scratches form on the bars, and the file becomes blunt.

To perform the work, you can also take a wooden bar and wrap it with sandpaper. First use a coarse-grained, then change it to a smaller one. Make sure that the surface of the glass is not touched when machining the ends, otherwise scratches will appear on it.

Work on the processing of the edges of the glass must be performed in cotton gloves, and to protect the eyes it is better to wear safety glasses.

Glass edging at home

Edging glass is a fairly time-consuming process that requires maximum accuracy and accuracy. Ideally, special equipment is used for such processing.

In the case when the cut glass is used for glazing of windows, doors or inserted into the frame, then there is no need for edge processing, of course. But if you plan to make glass doors in the bedside table, shelves or countertop, then there is no way without this process.

In order to qualitatively process the edge of the glass, it is necessary to consistently carry out two types of work - grinding with subsequent polishing.

To begin, process the edge of the glass with a grinding wheel with a large roughness (about 200 grit). At this stage, you need to get rid of the existing chipping and irregularities.

In order for the edge to become transparent and perfectly smooth, it must be properly polished. For this purpose, use a special felt or felt circle.

Apply the paste prepared from cerium oxide and water (consistency - liquid sour cream) onto the polishing wheel and gently polish the glass at low speed. Then gradually bring the pace to 1500 - 1800.

Glass processing at home

Glass is a very fragile material, but from it you can make a lot of useful and beautiful things. Moreover, one cannot do without it: it is in the windows, dishes are made of it, and much more. And how is it made? If you still do not know, we will reveal how glass is processed at home, because it consists of several stages. Using the information from this article, you can try your hand in this direction, creating decorative objects for your home.

At home, they usually grind and polish this material. For high-quality performance of these stages it is necessary to get the following tools:

Drilling.
Glass cutter.
Pliers.
By file
Grinder with the ability to change the speed of rotation. This is very important, as it is necessary that the fragile material does not overheat.
Velcro nozzle with which the grinding wheels will be fixed.
Grinding wheels of different grain. Their surface should be emery, resistant to moisture.

Important! Glass is not only expensive, but also unsafe. In order to avoid injury, goggles are worn over the eyes and cotton gloves.

When the primary, roughing of the glass edge is performed, it will become not only smooth, but also safe. However, the surface still remains quite rough.

Doing the glass edge with your own hands is done using ordinary pliers or a side cut-out of a glass cutter:

Glass should be grabbed in small sections, breaking off pieces of two to three millimeters in size.
Pliers are used to remove smaller protrusions. At the same time you need to firmly grab the material and gently squeeze the tool.

The choice of finishing method depends on the desired profile. It can be flat, shaped, trapezoid, etc.

Important! Using the rectilinear method, it is possible to set the desired angle up to 45 degrees. Thanks to the curvilinear method, the edge is given a shaped profile.

How to handle the edge of the glass at home?

Initially, a file is used for finishing. If the glass is thin, enjoy velvet.
Grinding bars can also be used. They can be carborundum and emery. To make the process easier and faster, kerosene or turpentine is used to wet the instrument.
For filing glass, especially thin, apply smooth movement.
If possible, the treated surface is placed under a water jet.
If it is necessary to obtain a straight edge, the material should be placed vertically, and then moved back and forth along the grinding bar.

Thanks to the grinding of glass, the surface becomes more perfect, the product becomes not only more beautiful, but also safer. Edge turns into a matte, slightly rough, greenish hue. Nevertheless, the appearance of her remains not very attractive, besides, the appearance of microcracks and small scratches is possible. To eliminate all irregularities, the edges are polished.

We already know how to grind glass at home, but polishing differs from this process, but only slightly. The most important thing - for processing the edges are not abrasive materials, and soft fibers. As a result, the edge turns into smooth and transparent, and the glass looks very aesthetic.

Solid glass products always have a polishing edge, as the design is even brighter. In addition, polishing is also performed if the glass is tempered, since then the material cannot be processed.

Important! Remember that glass is a very fragile material that does not tolerate overheating. Therefore, when working should not be in a hurry, you need to perform all actions carefully.

Polishing is done after grinding, using the fine-grained abrasive. This is a must-do, since the polishing belt will not be able to cope with the removal of large defects.

Important! After you learn to sharpen glass at home, you will notice that the residual stress on the surface is minimized. That is why during the transportation process the risk that the glass will be damaged will be significantly reduced.

When you are finishing, it is better to use old tools, as their surface deteriorates a lot.
Instead of a grinding stone, you can use a bar of wood, which is attached sandpaper.
Initially, tools with a coarse-grained surface are used, then transferred to a fine-grained one.
Do not rush, because due to the slipping of the tool may cause deep scratches on the surface.

As you can see, there is nothing terrible and complicated in the processing of glass. This can be done at home, using the minimum set of tools that every owner probably has.

If the glass is cut for doors, windows, or simply inserted into the frame with a portrait, then there is no need to process the edges of the glass. But, if they are used as shelves, doors, table tops for the coffee table, as the walls of an aquarium, etc., then the edge processing is required.

First, it is necessary for safety, because Sharp edges can easily get hurt, and secondly - to give the product an aesthetically attractive appearance, and thirdly, such glass processing will reduce the likelihood of cracks and chips.

Processing the edges of glass and mirrors is divided into two stages - grinding and polishing.

During mass production, furniture manufacturing, or commercial equipment, glass processing is performed on special vertical machines. But, at home, you can also do these operations yourself, using the tools at hand.

Let us consider in more detail - how to do grinding and polishing glasses with your own hands?

To do this, we will need such tools and devices: a drill or a grinder with a rotation speed regulator (we need small turns in order not to overheat the glass, 1200–1700 rpm), a special velcro attachment for fastening grinding wheels, grinding wheels themselves waterproof emery paper of different grain.

We fix the nozzle in the drill, put the disk, at first larger (100 - 200 grit) and do the grinding. First, we remove all the irregularities and notches, and after that we form the edge of the profile we need.

Grinding can be done on sandpaper, securing a special grinding wheel with a diamond-coated, having a certain profile, or simply flat.

The edge of the stele make a different shape: a semicircular (pencil), a trapezoid (European edge), a trapezoid asymmetrical, or any other. After this treatment, the side faces of the glass becomes slightly rough and dull. But, this is not the end.

After processing the surface with a large disk, we put a disk with a grain size of 300 - 600 grit, and at the end we process the edges with a small one - 1000 - 2000 grit.

For better polishing, the surface should be wetted, better of course, it should be done under a thin stream of water. But, experienced craftsmen can do grinding well and without water.

After this treatment, the side faces of the glass must be polished, after which the edges become smooth and transparent. Although, in some cases, the edges are still left unpolished, but this is individual.

The difference between polishing and grinding glass is that it is not made with abrasive discs, but with a soft felt wheel with a special paste. You can use the usual polishing paste GOI.

Apply the paste on a felt circle and polish the edges of the glass to shine, also using a drill with a nozzle, a grinder or putting a felt circle on sandpaper.

Glass is a very fragile material and is afraid of overheating, so all work must be done carefully, without haste and preferably with gloves.

This technology of grinding and polishing glasses can also be used in car repairs, to eliminate scratches and small chips on the glass. The requirements for transparency are higher there, so special polishing pastes are used. First, a scratch is ground with a grinding wheel, and then polished with a felt disc with a paste.

Maintaining optimal visibility in the car is one of the main conditions for safe driving. The windshield in this regard is the most responsible, but it is also the most open to minor damage and pollution. Minor scratches, chips, cuts and cracks have an impact not only on the coefficient of visibility, but also on the internal structure of the product. Therefore, the grinding of glass becomes a mandatory measure, which is produced in a regular manner at regular intervals.

Glass detection

In the process of defectoscopy, it is possible to assess how severe the wear of the surface is and to draw an appropriate conclusion about further actions. Sometimes after such an assessment, the glasses are removed and new ones are installed in their place. Most often, the check allows to determine the degree of damage - this will give the opportunity to more accurately select the means of grinding. The evaluation criterion is the depth of the defect. The first category is minor damage with scratches about 50 microns deep. Next comes the second category - these are cuts and small chips up to 200 microns. The most responsible polishing of the glass of the car is made when fixing damage, the depth of which is about 300 microns. In this case, requires a coarse grinding tool, as well as the corresponding paste. Conversely, in the case of minor cracks and cuts, fine-grained abrasives should be used. However, the choice of pasta should be discussed separately.

Choice of polishing paste

For ordinary motorists who plan to restore the glass surface in the conditions of their garage, it is recommended to buy pastes for manual processing. First, grinding glass with a manual tool has a less coarse and harsh effect on the surface, which eliminates the application of new cuts. Secondly, in terms of effect, they are not inferior to professional compositions, if used correctly. Most hand polishing pastes are based on chromium oxide, due to which this tool can be used for delicate surfaces - not only for autoglass, but also for polishing jewels, screens of mobile devices, etc.

There are also differences in this paste group. So, to eliminate obvious scratches and strong abrasions, you should purchase formulations with a rough base. These are not quite coarse-grained pastes, but you should also be careful with them, because with intensive exposure, not polishing, but in the literal sense, abrasive cutting will be provided. Grinding of glass that does not have deep damage can be done with soft compounds. They give a greater degree of cleaning effect, eliminating matte scuffs. There is also the category of decorative hand-made pastes, which are not so much struggling with damage, as they give the glass a shine.

Sanding preparation

Cleaning and restoring actions with the car body and glass are performed only after thorough washing. The machine must be washed, dried, and then treated with a blower. You will need to blow away small particles of dust that could remain on the surface of the glass. Next, you need to prepare a plastic film in an amount sufficient to completely cover the car.

The film should cover the entire body, and then make cuts in the windows and in the area of the windshield. This is necessary so that the abrasive does not fall on the non-target area. The edges of the cut film are neatly glued with masking tape.

Depending on the technique that will be used for windshield grinding, the corresponding tool is also prepared. Usually, a special grinding machine with an electric motor or battery pack is used for the operation, as well as a felt wheel in the form of a nozzle. At the same time it is necessary to dilute the abrasive paste with water, as provided for the instruction of a particular composition.

Technique of operation

For a start, the paste must be applied to the problem areas. This is done without the participation of the grinder - manually, the composition is applied to the felt wheel and rubbed over the target surface. Grinding is done in small circular areas with a diameter of about 30 cm. If it comes to a few point damaged areas, then attention should be focused on them. In any case, a long time to linger on the same place can not, otherwise a dent will be formed. Mainly grinding the glass should correct the physical defects of the structure, and for this, a soft impact will be enough. If dryness and temperature stress are observed at the treatment points, then a little water should be added to the glass surface. Upon completion, the entire composition is washed off, and the glass can be treated as special cleaning with special washing auto-chemistry.

How does polishing differ from grinding glass?

Glass polishing can also be an additional procedure after grinding. In essence, this is a more accurate operation of smoothing irregularities, since in the process of its implementation fine-grained materials are used. A polishing wheel, manual stripping materials and abrasive blends are also involved. As and windshield polishing allows you to eliminate minor defects. But its main task is to provide an attractive appearance of the surface with brilliance and the absence of dull abrasions.

Conclusion

Subject to the rules of grinding, you can minimize the disadvantages of the glass surface and enhance its initial decorative properties. However, one should not rely on this operation as a frequent and regular measure of glass restoration. In itself, the effect of abrasives contributes to the rapid wear of the material, so it is desirable to prevent the appearance of defects. Usually, glass is polished after a large number of small scratches and cracks have been formed. What can lead to such a condition? The most common factors experienced motorists include the impact of "janitors", cleaning with brushes and scrapers, stains from reagents, etc.

Glass is a very fragile and very dangerous material, so when working with it you need to observe utmost care and accuracy.

However, this process does not require professional training and can be performed at home. The main thing is practice!

How to cut glass with a glass cutter

Before you start cutting glass (or a mirror), you need to prepare all the necessary tools.

For the work we need:

Glass cutter (diamond or roller).
Long metal ruler.
Pliers with rubber pads (for breaking glass).
Rubber hammer.

You also need to take care of the glass itself. It should be at room temperature, dry and clean. To clean the glass of dust, you can use rags or baking soda solution. This moment is very important, because when working with “dirty” glass, a split can occur not along the cut line, but elsewhere the glass cutter itself fails faster.

Cut the glass on a flat surface. To do this, you can put it on a workbench or table, which is covered with a soft cloth.
The cut glass should fall on the table surface with the entire plane.
Next you need to attach a wide wooden ruler and at a distance of 1-2 mm. (for roller screw) and 3-4 mm. (for diamond), then hold the tool along the entire length of the glass, starting from the far side. The self-tapping screw at the same time needs to be kept perpendicular to glass.
If everything is done correctly, then a thin, colorless trace will remain on the glass, and the glass itself should produce a characteristic crackle when cutting.
If the glass is held together, and the cut line does not turn out to be smooth, it means that you are pressing hard on the tool, or you are working on the wrong side.
Next, the cutting line must be shifted evenly to the edge of the tabletop so that it protrudes by 3-4 millimeters.
Glass thickness up to 5 mm. break off with two hands a sharp movement to the bottom. At the same time hands should be located on the edges of the glass and protected by gloves.
If the thickness of the glass is greater, then several light blows are applied along the cutting line with a rubber mallet, and then break off just as well.
Passatizh with a rubber slip apply in the event that it is necessary to break off very thin part.

How to process edges

After the glass has been successfully cut on it, protrusions and nicks usually remain, which must be removed to prevent cuts or injuries.

It is best to handle the edges of the glass on special machines, but you can do this operation at home, but you need to perform this operation in cotton gloves.

To do this, take an emery board or an old file. If you use a file, you will need to prepare a small jar of kerosene or turpentine to moisten the instrument.

Edge processing

To process the glass edges at home, it is necessary to perform 2 actions: grinding and polishing.

For this action, a drill or grinder with a speed regulator is needed (glass grinding is performed at a low speed - 1200-1700 rpm), a special attachment with velcro and grinding wheels with waterproof sandpaper of medium and fine grit.

Work execution technology:

First, a larger emery paper is put on the grinding wheel (100-200 grit) and we form the edge of the profile we need.
Next, you need to put a disk with a grain size of 300-600 grit and repeat the previous operation, wetting the glass with a thin stream of water.
After that, the edges are processed with a disk with a grain size of 1000-2000 grit.
The last step is to polish the edges of the glass so that it becomes transparent. This is done using a soft felt wheel and a special paste (you can use regular GOI polishing paste). Polished glass is made using the same drill or grinder.

Important! Glass is a very capricious material and is afraid of overheating, so grinding and polishing work should be done slowly.

When we work with glass and transfer it from place to place, we must be especially careful with transportation, as it can easily break. Nowadays, glass creates many beautiful objects. Before you do them, you need to know how glass is processed. The processing of glass itself includes many stages in which you need to maintain accuracy and attentiveness.

What you need to work

Before you understand how to handle this fragile material, you need to know what kind of glass processing equipment is used?

If you do this important process at home with your own hands, then it is worth noting that all the work can be two stages:

Grinding.
Polishing.

In order to perform these steps qualitatively, several important tools are used. For example:

The grinder, which can change the rotational speed, is important when working with fragile material; In order not to overheat, the grinder should work at a speed of approximately 1200 to 1700 per minute.
You can also use a drill.
Requires specially created nozzle with Velcro, which is used to secure the grinding wheels.
Grinding wheels, which have an emery surface, resistant to water and different grain sizes.

Professional equipment

There are also special glass processing machines that are not used at home.

Such devices are used to perform work reliably and efficiently. Three main lines of processing equipment can be identified, which depend on the type of operation performed:

Walls for washing, cutting and drilling.
Polishing, grinding and milling stations.
Tools for processing the edge and facet.

You can also mention such equipment, which is specifically designed for the work of a narrow direction. For example, there are machines that are created to process glass and large glass.

How is processing performed

One of the stages of work is the processing of glass edges. Although special tools are used in professional workshops, at home it is most convenient to use a grinder and file. There are two types of files:

Personal.
Velvet.

Velvet file is used for thin, and personal file is used for thick material.
When work begins with a file, it needs to be wetted either with water or kerosene, or you can use a 10 percent solution of camphor, which is based on turpentine.

Grinding bars are also used in two types:

Carborundum.
Emery.

Carborundum bars can not wet. When working with the edge of the glass sheet, it is not advisable to press on the tool, and the movements should be along the edge. You need to remember that you need special care when the glass is very thin.

A little bit about the professional machine

You can consider in more detail the machine for processing the edges of the glass, which is used to grind and polish the edge of the sheet material. The equipment incorporates a special air purification system.

This system consists of three parts, two main filters and one control. If the check is clogged, it becomes clear that you need to clean the main filters. Also on this machine there is a specially equipped tape that processes the edge. There is also a special air cushion in this equipment, which helps the workpiece to move smoothly over the area of the table. Air is supplied through special small holes that are made in the table. When this function is turned on, a sheet of glass, as it were, hovers around the table, very easily moves in different directions.

Processing methods

There are two ways glass is processed. For example:

Decorative cold.
Chemical.

The first common method is sandblasting glass. It is performed by a special apparatus. Compressed air feeds a stream of sand onto the surface of the material that is being processed.
