How to process edges at the mirror. Stages of grinding and polishing glass edges

Maintaining optimal visibility in the car's cabin is one of the main conditions of safe driving. The windshield in this regard is most responsible, but it is the most open for small damage and pollution. Small scratches, chips, cuts and cracks affect not only the coefficient of visibility, but also on the internal structure of the product. Therefore, grinding glass becomes a mandatory measure, which is carried out regularly at certain time intervals.

Defecting glass

In the process of flaw detection, it is possible to evaluate how serious the surface wear is, and make the appropriate conclusion about further actions. Sometimes after such an assessment, the glass is dismantled and new ones are installed on their place. Most often, the verification allows you to determine the degree of damage - this will make it possible to more accurate the grinding agents. The criterion for estimates is the depth of the defect. The first category is minor damage with scratches of a depth of about 50 microns. This is followed by the second category - these are cuts and small chips up to 200 microns. The most responsible grinding of the car glass is made when fixing damage, the depth of which is about 300 microns. In this case, a coarse grinding tool is required, as well as the corresponding paste. And on the contrary, in the case of minor cracks and cuts, fine-grained abrasives should be used. However, the choice of paste should be told separately.

Choosing polishing paste

For ordinary motorists planning to restore the surface of the glass in the conditions of its garage, it is recommended to acquire pastes for manual processing. First, grinding glass with manual means is less coarse and rigid effect on the surface, which makes it possible to exclude the application of new cuts. Secondly, in terms of the effect, they are little inferior to professional compositions, if they are properly used. The majority of manual polishing pastes contains chromium oxide, due to which this tool can be used for delicate surfaces - not only for auto drain, but also in the polishing of jewels, screens mobile devices etc.

In this group, the paste also has its differences. So, to eliminate explicit scratches and severe scratches, the compositions with a rough basis should be purchased. These are not very coarse-grained pastes, but with them, too, it is necessary to be careful, because with intensive exposure it will be ensured not polishing, but in the literal sense abrasive cutting. Grinding glass that does not have deep damage can be made by soft compositions. They give B. more than The effect of cleaning, eliminating matte loss. There is also a category of decorative manual pastes that are not so much struggling with damage, as they give the glass jewelry shine.

Preparation for grinding

Cleansing and restoring actions with the body and windows of the car are performed only after careful washing. The machine must be washed, dried, and then processed by the blower. To blow up the fine particles of dust, which could remain on the surface of the glass. Next, it is necessary to prepare a polyethylene film in a volume sufficient to complete the car coverage.

Film should be covered with the whole body, and then make slots in the windows and in the zone windshield. This is necessary so that Abrasive does not hit the incompetent area. The edges of the circumcised film are neatly glued with painting tape.

Depending on what technique will be performed by grinding windshield, prepared and the corresponding tool is prepared. Usually for operation use special grinding machine With an electric motor or battery pack, as well as a felt circle in the form of nozzles. At the same time, it is necessary to dilute the abrasive paste with water, as provides for the instruction of a specific composition.

Technique performing an operation

For the beginning, the paste must be applied to problem areas. This is done without the participation of the grinders - manually applied to the felt circle and is rubbed on the target surface. Grinding is performed by small circular zones with a diameter of about 30 cm. If it comes to several point damaged areas, then attention should be concentrated on them. In any case, it is impossible to linger in the same place for a long time, otherwise the dent will be formed. Mainly grinding glass should correct the physical disadvantages of the structure, and for this it will be a sufficiently soft impact. If dryness and temperature voltage are observed at the processing points, it should be slightly adding water to the glass surface. Upon completion of the work, the whole composition is washed off, and the glass can be treated with a special detergent auto-chemistry as an additional purification.

What polished differs from glass grinding?

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 execution, fine-forming materials are used. Also involved a polishing circle, manual materials Stripping and abrasive mixtures. Like the frontal grinding allows you to eliminate small defects. But the main task is precisely the provision of an attractive appearance of the surface with the glitter and lack of matte scuffs.

Conclusion

Subject to the rules of grinding, you can minimize the flaws of the glass surface and increase its initial decorative properties. However, it is not necessary to count on this operation as a frequent and regular measure of the repair of glass. In itself, the impact of abrasives contributes to the rapid wear of the material, therefore it is desirable to prevent the appearance of defects. Usually grinding glass is performed after the formation of a large amount of small scratches and cracks. What can lead to such a state? The most common factors experienced motorists include the impact of "janitors", cleaning with brushes and scrapers, spots from reagents, etc.

Cut off. With cutting, keep the glass cutter vertically with respect to the glass, pressing it from above index finger. Cut the glass cutter along the level rail or insulating tape. Start from the end. Drive the glass cutter on yourself, pushing the surface evenly. Cut out only once. Before choking, put a match at the end of the end. Carefully knock the hammer on the incision, so it will turn into a smooth fellow.

Take a file, for thin glass suitable, to better take personal. Put a small jar with kerosene or turpentine to constantly wet the file. You can still apply a solution of camphores in turpidar in terms of 1 to 10. From the grinding bars, use essay and carborunds; By the way, the latter can not be saved.

Start painting the glass along its edge. Work very carefully, especially with a subtle material. To get a straight edge, glass move back and forth on the surface of the bar. Constantly wet the tool in the cooked composition.

For this work, use old emery bars and old files, since scratches are formed in the grinding on bars, and the file is fascinated.

You can also take wooden barber And wrap it emery paper. First use coarse-grained, then change it into smaller. Make sure that when processing the ends, the surface of the glass itself does not fall, otherwise the scratches will appear on it.

Works on the processing of the glass edge must be performed in cotton mittens, and it is better to wear safety glasses to protect the eye.

Processing the edge of the glass is a time-consuming process that requires the wizard of marginal accuracy and accuracy. This procedure can be performed as on special equipment in specialized workshops and at home with the help of an affordable tool.

You will need

- glass cutter;
- pliers;
- sandpaper
- carborund stone;
- Water.

Instruction

Remember: glass processing is produced can be in two stages: by grinding the edge of the glass and its polishing. In the process of grinding the edge of the glass remains rough, but it is aligned and becomes more secure. During polishing, the edge acquires a transparent look as well as a smooth surface.

Perform rough processing of glass edges using pliers or glass cutters (more precisely, the excavation on its side side). This procedure is carried out as follows: Capture a 2-3 mm tool of the protruding edge of the glass used and, moving up or down, shake sharp protrusions. If the protrusions are small, they can be "to query", clamping and firmly squeezing with pliers.

Finishing processing is carried out by two methods: straight and curvilinear. Rectilinear processing will allow you to get profiles different types: Trapezoid, flat, rounded, and also shaped

After you cut off the desired piece of glass, it is necessary to process its edge. This procedure does not take much time, but requires accuracy and attention. So how to process the edge of the glass?

To make the edge of the glass as you can, it is necessary to cut it correctly. With cutting, keep the glass cutter vertically with respect to the glass, pressing it from above the index finger. Cut the glass cutter along the level rail or insulating tape. Start cut from a long end. Drive the glass cutter on yourself, pushing the surface evenly. Cut out only once. Before breaking the glass, put the matches at the end of the end. Carefully knock the hammer on the incision, so it will turn into a smooth fellow.

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

Take a file, velvet is suitable for thin glass, it is better to take personal for a thick. Put a small jar with kerosene or turpentine to constantly wet the file. You can still apply a solution of camphores in turpidar in terms of 1 to 10. From the grinding bars, use essay and carborunds; By the way, the latter can not be saved.

For this work, use old emery bars and old files, since scratches are formed in the grinding process, and the file is fascinated.

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

Works on the processing of the glass edge must be performed in cotton mittens, and it is better to wear safety glasses to protect the eye.

Processing glass edge at home

Processing the glass edge is a rather time-consuming process that requires maximum accuracy and accuracy. Ideally, such treatment use special equipment.

In the case when the cut-off windows are used for glazing windows, doors or inserted into the frame, then the need for edge processing, of course, no. But if you plan to make glass doors in a bedside table, shelves or countertop, then without this process it is not necessary.

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

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

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

On the polishing circle we apply a paste prepared from cerium and water oxide (consistency - liquid sour cream) and gently polish the glass on small revs. Then gradually bring the turnover to 1500 - 1800.

Glass processing at home

Glass - material is very fragile, but from it you can make a lot of useful and beautiful. In addition, without it, it is not necessary: \u200b\u200bit is in the windows, the dishes are made from it and much more. And how does the manufacturer? If you do not know yet, we will reveal how the processing of glass is performed at home, because it consists of several stages. With the help of information from this article you can try your strength in this direction, creating decorative items for your home.

At home, it is usually performed by grinding and polishing of this material. For high-quality execution of these stages, you should get the following tools:

Drill.
Glass cutter.
Pliers.
Fire.
Bulgarian with the ability to change the speed of rotation. This is very important, since it is necessary that the fragile material does not overheat.
A velcro nozzle with which grinding circles will be fixed.
Grinding circles of different graininess. The surface of them should be emery, stealing moisture.

Important! Glass is not only expensive, but also unsafe material. In order to avoid injury, protective glasses are put on their eyes, and on the hands - cotton gloves.

When the primary, rough processing of the edge of the glass is performed, it will not only be even, but also safe. However, the surface still remains sufficiently rough.

The processing of the edge of the glass with their own hands is performed using conventional pliers or side excavation of glass cutter:

Glass need to capture small sites, Lambs the pieces of two or three millimeters.
Pliers are used to remove smaller protrusions. In this case, it is necessary to firmly capture the material and smoothly surpassed the tool.

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

Important! Using the straight-line method, the possibility of setting the desired angle to 45 degrees. Thanks to the curvilinear method, the edge attached a figure profile.

How to treat glass edge at home?

Initially, a file is used for finishing. If the glass is thin, use velvet.
You can also use grinding bars. They can be carborundum and essay. To make the process easier and faster, kerosene or turpentine is used for wetting the tool.
For filling glass, especially thin, smooth movements are applied.
If there is an opportunity, the processed surface is placed under a water jet.
If it is necessary to obtain the rectilinear edge, the material needs to be installed vertically, and then move it back and forth on a sharpening bar.

Thanks to the grinding glass, the surface becomes more perfect, the product becomes not only more beautiful, but also safe. The edge turns into a matte, slightly rough, greenish shade. Yet, appearance She remains not very attractive, besides, the appearance of microcracks and small scratches. To eliminate all irregularities, the edges are polished.

How to polish the glass at home, we already know, but polished differs from this process, but slightly. The most important thing is not abrasive materials, and soft fibers are applied to the edge processing. As a result, the edge turns into a smooth and transparent, and glass looks very aesthetically.

Solid glass products always have a polishing edge, as the design is even brighter. In addition, polishing is also performed in the event that the glass will be hardened, since then the material is then impossible.

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

Polishing is performed after grinding is performed, using the fine-grained abrasive. This is necessary to do, since the polishing tape will not be able to cope with the removal of large defects.

Important! After you learn to point glass at home, you will notice that the residual voltage on the surface comes down to a minimum. That is why in the process of transportation will significantly reduce the risk that the glass will be damaged.

When you perform finishing processing, it is better to use old instruments, since their surface will deteriorate much.
Instead grinding stone You can use a tree bar on which sandpaper is attached.
Initially, the tools with a coarse-grained surface are used, then moving to fine-grained.
It is not necessary to hurry, because due to the scoring of the tool, the appearance of deep scratches on the surface is possible.

As you can see, there is nothing terrible and overshadowed in glass processing. This is quite possible to do at home using a minimum set of tools, which, for sure, has every owner.

It happens that a completely new car already after passing 2-3 thousand kilometers upsets abundantly scratched windshield. The factors that lead to this can be quite a lot. It is a road trash that raised by the wheels of other machines, and the so-called "sandblasting", stones.

Road trash, sandblasting and stones can lead to the appearance of scratches on the windshield

Special danger, in particular, create brushes of conventional wiper. As a result, the driver becomes before choosing: make a replacement for damaged items or figure out how and how can the windshield can be polished at home. Based on the fact that the price of the new glass sometimes stops, let's stop in more detail in the second version of the problem solving.

How and what can polish the windshield of the car

It is important to immediately weigh your strength, as the glass is not at all the material that is easy to polish. At the same time, it is necessary to separate the concepts of polishing and grinding. The latter, by the way, is practically no applied as a procedure for restoring automotive glasses.

For polishing work, a corresponding machine will be required. It's available to it a large number of circles of various diameters (selected depending on the area of \u200b\u200bdamaged glasses), as well as varying degrees of abrasive ability.

For polishing windshield, the corresponding polishing machine will be required

The "polisher" is convenient because there is the possibility of connecting the channel to it to constant water supply to the processed area. Wetting the contact zone is difficult to overestimate, as this effectively levels large temperature differences on the surface treated, which arise as a result of friction force.

But at the same time, it makes no sense for the sake of polishing the windshield to buy a special electrical engineering, because in this case the budget of the ventiy will increase repeatedly. Well, if you can borrow a toolkit for several hours of friends, a neighbor in a garage, etc. In principle, it is possible to do with an ordinary drill, for which to acquire a special polishing nozzle will not be a serious investment.

Among other materials necessary for polishing must be listed:

abrasive paste;
malyary Scotch;
film to protect other surfaces of the car;
a set of microfibrous napkins;
special glass cleaner;
manual sprayer for water;
color marker.

Pedamental polishing of windshield at home

For the sake of polishing windshield, it is not worth buying a special electrical engineering, because the budget of the ventiy will increase many times

Starting work should always be with a thorough car wash. In the event of even conventional grazing in the polishing zone, new, deeper, furrows and other damage will immediately appear on the glass. Also, ideally the body should be covered by protective polyethylene filmon which the "window" is neatly cut to work with glass. The edges of this window must be fixed with scotch.

If the zone of damage is small, such as a single scratch, then you can do the usual "frame" from the painting tape with curved edges. Scotch clearly zones the windshield and does not allow splashes from a polishing circle to fly away for a long distance. In any case, the place of damage to the glass from the cabin is burned by a marker. This will not lose sight of the scratched area, even in conditions of application of polishing paste.

Eliminate the wiping from the "janitors" with your own hands

Fastened on the headside of "janitors" do not penetrate deeply, the thickness of the spoiled layer of just a few microns

Two "arcs" from wiper brushes - very frequent phenomenon on the windshield. Usually such defects do not penetrate deeply and imply the presence of a spoiled layer with a thickness of several microns. To remove completely mattness actually with the help of the finished abrasive circle for the primary processing or a conventional felt circle with polishing paste applied to it.

In the case of using paste, it is necessary to evenly distribute the composition throughout the processed area, and then start polishing, constantly moving the polishing circle. It is not recommended to delay the machine in one place, as overheating and cracking of the material may occur. It can not be allowed to dry the polyteroli if you feel that polishing it became harder, moisten the surface with water from the spray. However, it is not worth overdoing with moisture, otherwise the aquaplaning will begin and efforts will have to be more.

How to bring the transparency of the glass to the ideal

When polished, it is necessary to periodically stop and flush with the processed zone the remains of the paste to inspect the performance. It is important to visually analyze the surface from different angles and make sure that the need for further polishing.

When the goal is polished relative to the large area, it will be appropriate to draw back side Glasses Conditional boundaries, share everything for squares. In this case, when moving from one cell to the second, it is necessary to make the "Vangest" polishing so that there are no unprocessed bands and the restored glass has a homogeneous surface.

During processing, it is necessary to ensure that the polishing circle of the glass is at an angle of about 5º. Turns It is advisable not to raise above 2000, the optimal indicator is 1500-1700 rpm. The total amount of time spent time is usually 2-5 hours. After completion of the procedure, wash the glass with the help of water and a special cleaner, and then wipe all dry with a microfiber cloth.

Get rid of serious scratches

If the windshield has deep damage, hope to fully restore initial view Details are not worth it

When we are dealing with deep drums of windshield, such as scratches from sharp metal objects, Hoping for a complete restoration of the initial type of detail is not worth it. With a desperate attempt to focus all his strength on a difficultly disposable furrow, you risks either cause overheating and the destruction of the windshield, or get a noticeable recess in this place.

When removing a substantial layer of glass changes its geometry. Thus, the driver can observe the formation of diopters, a similar similarity of lenses, which noticeably distort the picture and negatively affect the perception of the road situation. Eyes from such glass quickly get tired.

Experts say that it is only possible to partially eliminate the negative effect of deep scratches, slightly smoothding its sharp edges with a polishing circle. For good lighting Such defects still remain noticeable. Even the use as an alternative to filling the cavity of the scratch by photopolymer will allow to eliminate the problem by only 70-80%.

Sandpaper and other "classic" means for polishing glass

Many in the old manner prefer the use for removal of mattness, scratches are not modern pasta, but the old good "sandpaper". For such purposes, a fraction is approaching 600 to 2500 - depending on the depth of damage (the more seriously the defect, the larger the grain).

The work in this case is performed manually, but it does not prevent regularly moisturize the contact surface with water. After a rough processing of problem areas, it is recommended to polish the glass of paste of soft exposure. As a rule, this is the so-called diamond paste, which actually contains grapples of diamonds of 2-3 microns. Polishing can be carried out both with the help of power tools and manually.

You can also pay attention to the universal abrasive pastes like the "GOI" (based on chromium oxide), "polar" (based on cerium oxide) or Crocus (based on iron oxide) or the 90s. They are still sold in highways and can be effectively used to polish damaged windshield.

Approximate price of polishing agents

Below are the topical price tags of some popular compositions for polishing the windshield of the car:

cERIGLASS paste - 500 rubles. for 150 ml;
powder "Fluoropol" (Insafe) - 600 rubles. per 100 g;
paste "GOI" - 130-160 rubles. per 100 g;
diamond paste for rough finishes - 1,205 rub. for 40 g;
diamond paste for finishing polishing - 101 rubles. For 40 g
