Do-it-yourself cutting and straight processing of glass edges. Face processing How to sharpen glass at home

Processing the end of a glass sheet or mirror on the finished product is mandatory. Cutting leaves irregularities, holes and microcracks along the cut border. It's not even a matter of lack of aesthetics, but of basic safety.

An untreated product may cause injury. Grinding or polishing the edges of the glass will remove sharp protrusions, trim the ends and refine them. Without this, you will only get a semi-finished product.

No matter how beautiful the product is called in the catalog, in reality its untreated edge will turn the most exquisite thing into a sloppy craft.

In addition to the aesthetic side and safety issues, edge processing is definitely necessary if the glass is to be tempered. An untreated edge during hardening will cause destruction of the product, since any microchip on it will not withstand the accumulated stresses.

Grinding

Grinding the edges of glass and mirrors is a simpler option for finishing work. Its essence is in the impact abrasive tool to the end of the sheet.

Each of us has done sanding at some point. It is produced manually or using special equipment. Industrial machine gives highest precision and cleanliness.

Therefore, you shouldn’t count on finishing the products yourself somewhere in the garage. Most likely, instead of saving on the order budget, you will almost ruin finished project. And you'll cut yourself again.

Industrial grinding smoothes the edge of the glass without changing the original cutting dimensions. The machine will remove thin layer material with bumps and micropeaks, without violating the specified perimeter of the product.

Sanding only neutralizes large irregularities. The edge remains rough to the touch and appears matte. Although completely safe. There may be small dents and defects on the polished edge - this is not a defect.

But a noble, discreet matte finish is in demand in design. For example, when making separately hung shelves, large mirrors or decorative elements for furniture and interior design. Therefore, edge processing is sometimes limited to grinding.

Polishing glass edges and mirrors

Polishing the edge is the best finishing option. It forms an absolutely smooth edge of a glass panel or mirror. If grinding is considered a technical operation, polishing is already pure aesthetics.

The shape of the glass end is important. In most cases, you will be offered the following polishing patterns:

Euroedge (trapezoid)

"pencil" (hemisphere)

edge polishing at 45 degrees

"cascade"

Euro edge is more common than others. This is a perfectly smooth polishing of the glass end with small chamfers in the upper and lower planes of the sheet at 45 degrees. The chamfer width is usually several millimeters. Euroedge - universal solution. Goes with everything.

When processing "pencil", the end is rounded. Like a ground eraser on the blunt end of a pencil. This is done on mirrors and glass furniture parts.

An edge at 45 degrees is less common, but in some cases such processing cannot be avoided. For example, in the manufacture of certain types of shower doors, for normal opening, exactly this bevel is required on the inner edge of the door (the side with hinges). Also, this treatment is found in UV bonding. Well, aesthetically it looks unconventional and beautiful.

The cascade edge is used for countertops and designer products. It looks great in decorative sets. The cascade is a smooth rounded bevel with two radii, with a “hollow”.

No defects are allowed on the polished end.

Glass and mirror edge polishing technology

Polishing is carried out on special machines with soft abrasive wheels. Depending on the settings, the machine forms an edge of the required shape.

Although the polishing operation is understandable, it requires precise equipment and highly qualified personnel. The quality of processing is affected by:

Only a fusion of all 3 components will give an ideal result. And this is exactly the kind of alloy we provide!

Features to consider

The ends of tempered and bent glass are processed in advance. That is, they first grind or polish. And only then they bend and harden. Reversing the order will destroy the sheet.

Polishing the edge of triplex has a number of its own characteristics. Glasses can be processed separately before gluing, or ready-made triplex can be processed (polishing in a package).

In the first case, there may be some divergence of the layers and the edge will look like 2 joined processed ends.

When processed in batches, the end of the triplex looks the same as if the triplex were just a sheet of ordinary glass.

The Vertmax processing center is currently a unique innovative development of Intermac in the field of complex processing of glass products.

When processing glass, close attention is paid to the edges. This is largely due to the importance of this process. After all, competent processing of the glass edge is intended not only to give the glass the highest aesthetics, but also to prevent the possible occurrence of chips and cracks, which significantly affects the safety during operation of the glass.

Of course, there are many ways in which glass edges are processed; the choice of a specific processing method entirely depends on the conditions of use of the glass product. So, for example, there is no need to apply processing High Quality For glass that will be used with a frame, it will be more than enough to remove irregularities and dull sharp edges.

Which actually does not at all contradict safety requirements. But for products made of tempered material, high-quality glass edge processing is extremely necessary. In addition, the edge processing process largely depends on the properties of the glass itself, as well as the presence and size of various holes.

Types of glass edge processing

1. Technical grinding. The purpose of this grinding is to dull the sharp edges of the glass.

2. Edge grinding. Completely eliminates all kinds of cuts, and the surface of the edge becomes matte or rough.

3. Polishing the edge. At the same time, the edge of the glass becomes smooth and transparent.

4. Facet. This type processing is aimed at the beveled side edge mirrors

5. Blunting of corners. Pursues the goal of increasing safety, for example, glass table tops or doors.

Glass edge processing equipment

For a process such as glass edge processing, use specialized equipment, with which you can perform both grinding and polishing. Such operations are performed after the glass has broken. The end result of these actions is to obtain a straight European edge, as well as chamfers with an angle of 45 degrees.

The standard equipment for processing glass edges includes:

1. Bed (the largest structural element).
2. . The conveyor belt serves for the safe supply of glass.
3. Feed drive.
4. Feed speed regulator. It is worth noting that it is stepless.
5. A mechanism that provides adjustment and regulation of the feeding conveyor.
6. Guides. Roller guides are predominantly used.
7. Equipment for grinding.
8. Electric motor. Of course, its main task is to drive the spindle.
9. Control panel.
10. Cooling system.

Glass processing equipment is designed to meet the most stringent safety requirements. The control panel provides remote access to all important nodes apparatus. Processing of glass edges must be carried out in full compliance with established technological and technical standards, with mandatory observance of safety regulations for the working process. Only with strict compliance with all glass processing requirements is it possible to obtain high-quality results.

Products made using special equipment are quite in demand on the market. Of course, this is largely due to the wide range of applications of high-quality processed glass. Such glass finds its application in the manufacture of double-glazed windows, both with wooden frames, and with plastic ones. Also, such glass is very actively used in. The use of high-quality processed glass is also very important in the manufacture of various types of showcases.

Do-it-yourself glass processing. How to do it correctly.

Glass is a very fragile and very dangerous material, so when working with it you need to be extremely careful and careful.

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

How to cut glass correctly with a glass cutter

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

For work we will need:

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

You also need to take care of the glass itself. It must be room temperature, dry and clean. To clean the glass from dust, you can use a rag or solution baking soda. This point is very important, since when working with “dirty” glass, a split may occur not along the cut line but in another place and the glass cutter itself will fail faster.

1. Glass must be cut on a flat surface. To do this, you can place it on a workbench or table that is covered with a soft cloth.
2. The glass to be cut must lie flat on the table surface.
3. Next, you need to apply a wide wooden ruler at a distance of 1-2 mm. (for a roller screw) and 3-4 mm. (for diamond), then run the tool along the entire length of the glass, starting from the far side. The self-tapping screw must be kept perpendicular to the glass.
4. If everything is done correctly, a thin colorless mark will remain on the glass, and the glass itself should produce a characteristic crackling sound when cutting.
5. If the glass holds together, but the cut line is not straight, it means you are pressing hard on the tool, or you are working on the wrong side.
6. Next, the cutting line must be moved evenly to the edge of the tabletop so that it protrudes by 3-4 millimeters.
7. Glass up to 5 mm thick. break off with both hands with a sharp downward movement. In this case, hands should be positioned along the edges of the glass and protected with gloves.
8. If the thickness of the glass is greater, then apply several light blows with a rubber mallet along the cutting line, and then break it off in the same way.
9. Pliers with a rubber pad are used if it is necessary to break off a very thin part.

How to finish the edges

Once the glass has been successfully cut, it usually leaves ridges and nicks that must be removed to prevent cuts or injury.

It is best to process the edges of the glass on special machines, however, this operation can be done at home, but this operation must be performed in cotton gloves.

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

Edge processing

To process the edge of glass at home, you need to perform 2 steps: grinding and polishing.

For this action, you need a drill or grinder with a speed regulator (glass grinding is done at low speed - 1200-1700 rpm), a special attachment with Velcro and water-resistant grinding wheels sandpaper medium and fine grain.

Work technology:

1. First, coarser sandpaper (100-200 grit) is placed on the grinding wheel and we form the edge of the profile we need.
2. Next, you need to put a disc with a grain size of 300-600 grit and repeat the previous operation, wetting the glass with a thin stream of water.
3. After this, the edges are processed with a disc with a grain size of 1000-2000 grit.
4. The last step is to polish the edge of the glass to make it transparent. This is done using a soft felt circle and a special paste (you can use regular GOI polishing paste). Glass polishing is done using the same drill or grinder.

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

How to sharpen glass at home - Elfterra.ru

The glass is placed on absolutely smooth surface(for example, a plastic tabletop kitchen table). The glass cutter must be held so that the index finger is on top, and the tool itself is in a position close to vertical.

A glass cutter is used using a ruler or a straight edge. Instead of lath, you can also use insulating tape.

Start cutting from the far edge of the canvas. The glass cutter is passed along the surface - towards itself - only once, pressing evenly on the glass. The glass should make a faint cracking sound.

When working properly good glass cutter a thin colorless line should remain on the glass. If it looks like a rough scratch white, it means your movement was incorrect or you are using a dull glass cutter.

A dull roller glass cutter can be sharpened using a fine-grained emery wheel.

If the cut doesn't work out the first time, don't despair - turn the glass over and repeat the cut on the other side.

To do this, at the beginning of the proposed cut, you need to make a notch on the glass with a triangular needle file, then a few millimeters from it along the line of the future cut, heat the glass with a soldering iron tip until a crack appears from the mark to the heating point. So, gradually moving the soldering iron, you need to go along the entire line.

To speed up the process, you can cool the glass from time to time with a damp cloth.

For thick glass it is better to take a personal file, for thin glass - a velvet one.

The sharpening stones you can use are emery and carborundum, and the latter do not need to be wetted. When working, do not press hard on the glass; The glass should be filed not across, but along its edge.

The thinner the glass, the more carefully you need to work.

It is necessary to keep in mind that the file and whetstones deteriorate greatly during such work: the file becomes dull and scratches form on the whetstones. Therefore, it is advisable to use old files and old emery blocks to polish the edge of the glass.

When processing the edge of glass, you must wear cotton gloves.

The tip of the drill is heated white, and then quickly pressed into the sealing wax and held until the sealing wax stops melting.

When drilling, the tip of the drill is generously moistened with turpentine.

Small glass objects Can be drilled in water.

To do this, you need to prepare a paste consisting of coarse emery, camphor and turpentine: 1 part of powdered camphor is dissolved in 2 parts of turpentine and mixed with 4 parts of coarse emery. The resulting paste is applied to the place where the hole needs to be drilled.

A piece of copper wire is clamped into the drill chuck.

It is convenient to drill glass through plywood (conductor) that has guide holes.

The glass must lie on a hard and level surface.

To do this, use one of the following methods;

On the glass around the intended hole, a fence in the form of a ring with an internal diameter of 40-50 mm and a height of 8-10 mm is made of plasticine or putty.

Corundum powder is poured inside the ring (it can be easily prepared by grinding a piece of unusable emery wheel). The powder is poured a small amount water to make a liquid slurry, after which they begin drilling.

A small mound of slightly moistened river sand is poured onto the surface of the glass, previously thoroughly degreased with acetone, gasoline or alcohol.

Using a sharpened stick, make a conical depression in it and clear an area equal to the future hole from sand. Molten solder is poured into the resulting sand mold at a temperature of 250-300 C.

After the solder has cooled, the sand is removed, and the solder cone is removed along with the glass circle stuck to it.

To cut a large glass round hole, you must first drill a small hole in the center, then strengthen one end of the wire in it, and attach a glass cutter or diamond to the other end and cut a circle with it.

Then, using a glass cutter or diamond, several radii are drawn along a ruler from the hole to the circle line. After this, they take the glass in their hands and reverse side quietly hit with the wooden handle of a hammer.

The cut pieces of glass should fall out.

It is advisable to knock out the cut out pieces of glass in water. This reduces the likelihood of damage to the glass being processed.

To roughly trim jagged edges after trimming, use pliers, which do not break off the protruding pieces of glass, but, carefully pressing on the edge of the glass with the very ends of the flat lips of the tool, gradually and little by little crumble or crush the edges of the glass.

The glass edge processing technology is similar to the glass edge processing when cutting it.

After you have cut the desired piece of glass, you need to process its edge. This procedure does not take much time, but requires care and attention. So how do you process the edge of glass?

To make the edge of the glass as smooth as possible, it is necessary to cut it correctly. When cutting, hold the glass cutter vertical to the glass, pressing it from above with your index finger. Use a glass cutter to run along a smooth strip or insulating tape. Start cutting from the far end. Guide the glass cutter towards you, pressing evenly on the surface. Only do it once. Before breaking off the glass, place a match at the end of the cut. Gently tap the cut with a hammer until it becomes a straight cut.

After cutting, proceed to processing the edge of the glass. Once cut, the glass has ridges and jagged edges as well as sharp edges. It is better to process the edge of the glass on special machines, but this method cannot be used at home.

Take a file; for thin glass, a velvet file is suitable; for thick glass, it is better to take it personally. Place a small jar of kerosene or turpentine nearby to constantly wet the file. You can also use a solution of camphor in turpentine in a ratio of 1 to 10. For sharpening stones, use emery and carborundum stones; By the way, the latter do not need to be wetted.

Start filing the glass along its edge. Work very carefully, especially with thin material. To get a straight edge, move the glass back and forth across the surface of the block. Constantly wet the instrument in the prepared mixture.

For this work, use old sanding blocks and old files, as the sanding process creates scratches on the blocks and dulls the file.

To get the job done, you can also take wooden block and wrap it with sandpaper. Use a coarse one first, then change to a finer one. Make sure that when processing the ends you do not touch the surface of the glass itself, otherwise scratches will appear on it.

When processing glass edges, it is imperative to wear cotton gloves, and to protect your eyes, it is better to wear safety glasses.

The technological process of glass production is very complex and requires special conditions (such as, for example, a high-temperature furnace) and specific materials, not to mention special knowledge and skills. Therefore, it is very difficult to organize glass production at home. However there is

Almost every owner sooner or later has to pick up a glass cutter and cut out glass the right size. Without special skills and using ordinary tools, few people manage to get an even cut the first time. To cut glass straight, follow these steps:

Processing the edge of glass is a rather labor-intensive process that requires maximum precision and accuracy. Ideally, special equipment is used for such processing.

In the case when cut glass is used for glazing windows, doors or inserted into a frame, then, of course, there is no need for edge processing. But if you plan to do glass doors in a nightstand, shelf or tabletop, then you can’t do without this process.

In order to properly process the glass edge, it is necessary to sequentially carry out two types of work - grinding followed by polishing.

First, sand the edge of the glass with a coarse sanding disc (about 200 grit). At this stage, you need to get rid of the existing nicks 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 a paste made from cerium oxide and water (the consistency is liquid sour cream) to the polishing wheel and carefully polish the glass at low speed. Then we gradually increase the speed to 1500 - 1800.

Glass is a very fragile material, but many useful and beautiful things can be made from it. Besides, you can’t do without it: it’s in the windows, dishes are made from it, and much more. How is it made? If you don’t know yet, we will reveal how glass processing is done at home, because it consists of several stages. With the help of the information from this article, you can try your hand at this by creating decorative items for your home.

At home, this material is usually sanded and polished. To carry out these steps efficiently, you should acquire the following tools:

• Drill.
• Glass cutter.
• With pliers.
• With a file.
• Grinder with the ability to change the rotation speed. This is very important, as it is necessary that the fragile material does not overheat.
• An attachment with Velcro, which will be used to secure the grinding wheels.
• Grinding wheels of different grain sizes. Their surface should be sandable and resistant to moisture.

Important! Glass is not only expensive, but also an unsafe material. To avoid injury, wear protective goggles over your eyes and cotton gloves on your hands.

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

Do-it-yourself processing of the glass edge is done using ordinary pliers or the side recess of a glass cutter:

• The glass should be grabbed in small sections, breaking off pieces two to three millimeters in size.
• Use pliers to remove smaller projections. In this case, you need to firmly grasp the material and gently squeeze the tool.

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

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

How to process the edge of glass at home?

• Initially, a file is used for finishing. If the glass is thin, use velvet glass.
• You can also use sharpening stones. They can be carborundum and emery. To make the process easier and faster, kerosene or turpentine is used to wet the tool.
• Smooth movements are used to file glass, especially thin glass.
• If possible, the surface to be treated is placed under a water jet.
• If a straight edge is desired, the material must be placed vertically and then moved back and forth along the sharpening stone.

Thanks to glass grinding, the surface becomes more perfect, the product becomes not only more beautiful, but also safer. The edge turns into a matte, slightly rough, greenish tint. Yet, appearance it remains not very attractive, in addition, microcracks and small scratches may appear. To eliminate all irregularities, the edges are polished.

We already know how to polish glass at home, but polishing differs from this process, but only slightly. The most important thing is that not abrasive materials, but soft fibers are used to process the edges. As a result, the edge turns smooth and transparent, and the glass looks very aesthetically pleasing.

Solid glass products always have a polished edge to make the design even more vibrant. In addition, polishing is also carried out if the glass is to be tempered, since it is then impossible to process the material.

Important! Remember that glass is very fragile material, which does not tolerate overheating well. Therefore, when working, you should not rush, you need to perform all actions carefully.

Polishing is done after sanding, using the finest abrasive. This must be done, since the polishing tape will not be able to remove large defects.

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

• When you do finishing work, it is better to use old tools, as their surface deteriorates greatly.
• Instead of a whetstone, you can use a block of wood with sandpaper attached to it.
• Initially, tools with a coarse-grained surface are used, then they switch to a fine-grained one.
• Do not rush, as slipping of the tool may cause deep scratches on a surface.

As you can see, there is nothing scary or overly complicated in glass processing. This can be done at home using a minimal set of tools, which every owner probably has.

Do-it-yourself straight-line glass edge processing (video)

(Last Updated On: 10/04/2017)

How to process glass edge

Work with glass is one of the most common types of work performed during home renovation– glass today is very popular in interior decoration and furnishings. Working with glass is labor-intensive and often practically impossible to do at home; for example, straight processing of a glass edge with your own hands, not to mention creating a curved line, will be a task that only a craftsman with extensive experience working with glass and special equipment can handle . However, some types of glass processing can be done at home, thereby reducing overall processing costs.

Common types of glass processing

Most often, glass is subjected to the following types of processing:

• cutting;
• edge processing;
• drilling

Cutting of these is the most common type. Cutting glass is quite simple, but you need to be careful and have at least minimal experience.

The glass should be placed on a flat and smooth surface, a template should be placed along the cutting line - this can be a ruler, wooden slats or electrical tape. Then take a glass cutter and place it almost vertically at the beginning of the cutting line. You need to cut towards yourself, using the glass cutter only once. You should not press too hard on the glass, and you should also not create a point pressure - you should press with equal force along the entire length of the cut. If everything is done correctly, a characteristic faint crackling sound will be heard.

If the glass cutter does not cut through the glass, it should be soaked in kerosene. However, this is only permissible if the tool has not lost its sharpness. If the roller becomes dull, it can be sharpened using fine-grained sandpaper. In a situation where suddenly the cut does not work out, you should not cut along the same line - you need to turn the glass over and repeat the cut on the back side.

Before breaking off the cut fragment, you need to tap the glass from below with a hammer. If the cut is small, then it is more convenient to break it off using special notches on the sides of the glass cutter or pliers.

Do-it-yourself glass edge processing

Edge processing, including straight-line processing of glass edges with your own hands, in ideal must be performed on special equipment, but the price of such a machine is very, very high, so only a few can afford to buy it. Therefore, at home, you have to process the edge of a cut sheet of glass using files or a sharpening stone. Depending on the thickness of the glass, the type of file is selected:

• for thick glass - a personal file;
• for thin glass - a velvet file.

During operation, the file should not be dry; ideally, it should be moistened with a 10% solution of camphor in turpentine; if such a solution is not available, kerosene or even plain water will do.

Straight-line processing of the glass edge should be performed by moving the glass back and forth along a fixed tool. In this case, you need to be extremely careful not to break the glass. You cannot move the glass across the instrument. It should also be taken into account that with such processing the tool quickly becomes unusable. Therefore, it would be unreasonable to use a new expensive tool for processing the glass edge - for this would be better suited old and no longer used for precise work file or whetstone.

When processing glass edges, you should wear gloves and safety glasses, which will protect the worker from damage from small glass filings. Because the main requirement for any work is its safety.
