How to label the wall without dust: accurate repair. Selecting a diamond disk

Very often, when repairs are faced with how to launch the wall without dust.

The fact is that often in where people are repaired, people live.

And dust does not affect health, and on well-being, and in general, nobody wants to live in the mud.

After a small repair, the duration of a couple of hours often have to make cleaning, which lasts half a day. Therefore, the question is more than relevant.

The perforator is a tool that should be in the arsenal of any homemade Masters or worker-electrician.

Usually use small professional vocabulars with SDS + cartridge.

It is undesirable to use large perforators and jackhammers, since it is unnecessary to break through it, exceeding the permissible depth of the short.

Also, such perforators usually have a lot of weight and are too heavy in operation.

The perforator must be a three-way, allowing the inclusion of a pure loaf mode. Double-mode perforators that allow only drilling and drilling with a blow, are not suitable. Do bad for these purposes and cheap perforators of the "home" class.

They, usually, not very well tolerate long-term loafing, and after two or three hours of such work, the gearbox, the cartridge assembly and other mechanisms may fail.

Watch the wall without dust with their own hands with the help of a perforator will not be much difficulty. Usually, the punch with a perforator is not too dusty. Much more large pieces are formed than dust. Nevertheless, the dust will still be. So that it does not fly around the room, use building vacuum cleaner.

In the extreme case, you can do and an ordinary vacuum cleaner. For work, you need a second person who will keep a vacuum cleaner near the zone of the stroke. He usually and trash sweeps and folds into the bag. Some have a built-in vacuum cleaner - for example, Makita 2432. Here you can do and the forces of one person.

For work, various chisels are used - blades of various widths, peaks, special groove chisels.

The most convenient for the stroke is a grocery blade.

It is a slightly bent, has the shape of a sympty shovel with curved edges.

Of course, the impact force of such a shovel will be worse than on a straight chisel, but in this case it is possible to produce continuously, without opening the spatula from the groove every 3-4 cm.

The blades and peaks are used where the groove blade is not possible to apply due to the high solidness of the wall - most often when the concrete is stroke. And also if there is no groove blades. When buying a tool, you must pay attention to its hardness and quality of steel.

It should have a hardening of the necessary hardness not only in the field of sting, but also in the shank area. The shank must be slightly riveted so as not to open and at the same time do not injure the puncher of the perforator when shuffles. It is better to overpay for the shovel than to throw the perforator.

Strobling with Bulgarian

Or an angular grinder - a power tool intended for cutting metal or stone materials by abrasive discs.

Pure sticking of the grinder, as a rule, does not apply.

Usually, the strides make extreme cuts with a grinder, and the middle is chosen using a perforator.

Such technology allows you to make a strobe more accurate, constant depth. The performance of the work also grows.

How to labby the wall under wiring without dust with a grinder? After all, the most important drawback when working with a grinder is just a huge amount of dust. The entire volume of the cut material turns into dust. You can solve the problem with the help of two ways: the use of wet cut and the use of a vacuum cleaner.

The wet cut with the grinder is rarely used due to the difficulties of implementation. No one wants to make a jet of water, which can pour neighbors on the walls in during the repair. Nevertheless, if other ways to apply cannot be removed, a wet reside can be used using special devices.

Sprinkle water by manually near the working disk can not be:

first, there is a danger of damage to the disk of another employee
secondly, when the water is hit on the Bulgarian itself, with inaccurate work, you can spoil the tool and get a blow to electric

The grinding of the grinder with the connection of the vacuum cleaner is carried out using special devices. They cost from 1.5 to 10,000 rubles. Good devices Allow not only sucking dust and prevent its scattering, but also to cut into a strictly defined depth, adjust it and increase productivity, convenience and safety.

When using such devices, it is easier to provide a smooth cut, fixing along the rack shock at the desired distance and pressing the device with one edge to it.

Strosure with special tools

For strobe laying in large volumes use specialized tool - Stroboresa.

In most cases, they have three cutting organs - on both sides they have two abrasive disks that make a cut on both sides of the shoes, and the middle is selected by a specialized cutter.

The perfect accuracy and depth of the shoes are achieved, all work is done in one pass.

A special building vacuum cleaner is connected to the strokesus, which sucks almost all dust.

The main disadvantage of strokesov is a single type of material. Most often they are designed to lay the stroke in, strokeshes for concrete and brick walls It is more expensive and have low performance.

At the same time, the chance of damage to the reinforcement is great - if in the case of a grinder and perforator, the reinforcement will be immediately noticeable, it is easy to not notice and cut with the strokesis.

It is undesirable to use some other tools for laying a strobe, undesirable. For example, when the stucco is not great depth There is a temptation to use the mill.

However, if accidentally discovers a small brick corner, which is closed by plaster - a mill or tool will break. The same with other tools. For manual sticking in small volumes, we use a jumper with a rubber protective gasket and a painting.

About sticking without dust with household vacuum cleaner You can look at the video:

Diamond tools under which, as a rule, mean diamond discs, is widely used in construction. Its popularity is due to the number of advantages inherent in him. Working with this tool, unlike perforator and jackhable equipment, occurs without any noise and vibration, which retains the integrity of the structures and does not irritate the hearing. The holes cut with a diamond tool are smooth and smooth, does not require cleaning and grinding.

Diamond disks serve to cut the materials such as ceramic or clinker tiles, reinforced concrete, brick or slag block, slate, asbatement, asphalt and other similar materials. It is diamond disks that allow processing stone and concrete quickly, neatly and with the minimum possible wear of the disc itself.

Diamond tools consists of two main elements: steel case and diamond-saturated segments. The method of fixing the latter may have different variants: Segmented edge, solid edge, gear edge or solid segment constituting a single integer with a cutting disk case.

In a diamond instrument, correctly selected for the material that will be processed, there is an optimal balance between the work of diamonds and the abrasive wear of the ligament; Diamond is held before destruction, then a new crystal is exposed. It is from this balance that the quality of the diamond instrument depends on.

Disc work surface

The working surface of the diamond disk can be both solid and segmental. The segmental surface is necessary to remove from the cut of small particles of the material being processed, which have an abrasive impact on the working surface of a diamond disc and can significantly reduce its service life.

The disk housing is a plate of specially treated and tempered steel. high Quality. Usually segments are located on the teeth, between which are depressions. They are also called slots. They contribute to the cooling of the disc during cutting, allowing water (wet cutting) or air (dry cutting) to pass between segments. They also allow the disk to be curled to a certain extent during cutting. Segments consist of a sintered mixture of diamonds and metal powder.

The segment or segment edge is a bit wider than the case, so that when the cutting edge penetration into the material, the steel is practically not worn about it.

Surface spraying

It should be noted that if the deposition working surface Diamond disk was finished, it will have to be replaced. The cutting effect on a stone or concrete is precisely the diamond spraying, without it, the steel disk will be much more, than the surface being processed.

Diamond Disc Principle

1. Diamond tool does not cut, and diamond crystals crushes the material being processed. Metal bunch holds crystals from falling out. In the process of working, diamonds are also supported by "comet tails" arising directly behind crystals and, reinforcing the holding effect of the ligament.

2. Diamonds discovered in this way cut into the material, turning it into small dust.

3. During the cutting, open diamonds can crack or break (the faster than the harder and densely cut material).

4. At the same time, the abrasive wear of the metal ligament of the segments of the material being processed is begins.

Dry and wet cutting

According to the sawing method, diamond discs are distinguished for dry and wet cut.

Dry cut

With a dry cutting, the diamond disk is attached to the tool, for example, an angular grinding (or a grinder) or a fuel reinforcement, just like ordinary cutting discs. The wet res imposes the presence of specialized stationary or portable equipment, which in the process of sawing carries out water or other fluid to the place of cutting. The wet res is used, for example, when working with asphalt, such a road machinery is equipped with a large diameter discs.

Wet cut

The wet red diamond disk allows you to achieve an accurate and very accurate section of such solid and at the same time fragile materials such as ceramic tiles, marble or glass. In this case, there is no separation of materials like marble, thanks high precision cut diamond disks.

The choice of the sawing method may depend on the user's preferences or from some specific restrictions related to the work performed.

When working on concrete, wet cutting is preferred, since with it the tool is cooled, which allows you to increase the cutting depth and increases the service life of the tool. In the case of clinker machines and stovetures, the tools for dry and damp cutting can be equally successfully used. In universal pulp on the construction site, the tool for dry cutting is most often used.

Wet cutting is used mainly to reduce the amount of dust and to cool the tool. If, with dry cutting with powerful hand-held cutters, there is beating, try using wet cutting. Wherein cutting disk will be cooled, which contributes to the elimination of this problem. Tools for dry cutting can be used both with feed and without water supply depending on the machine used and the material to be cut.

Selecting a diamond disk

For right choice Diamond disk should consider what machine for cutting will be used and what material must be processed. To implement a diamond cutting to a larger depth, select the diamond disk of the corresponding diameter. At the same time, the selected diameter of the diameter of the diamese disk should be approached by cutting machine.

Also, when choosing a diamond disc, it is necessary to take into account the size of the inner hole - it must correspond to the diameter of the cutting machine shaft. The gaps between the shaft and the inner opening of the disk are not allowed.

Depending on the type of material being processed, the shape of the diamond disk teeth is selected. This choice will affect the purity and processing speed. For processing some soft materials Diamond disks that have no teeth can be used to eliminate damage to such materials.

Even before buying a diamond disk, it is necessary to clarify several questions for themselves in order to navigate to choose a disc brand. Below are the main points that need to be taken into account:

Processed material;
Specifications and capabilities of the cutting machine used;
The required depth of cutting;
Type of cutting.

Installing a disc

Diamond disk must be properly installed on the car for cutting. Proper installation It implies that the direction of rotation of the machine shaft will coincide with the direction of rotation of the diamond disk provided by the manufacturer and the arrow indicated on the body. In some cases, the arrow on the housing may be absent, then you need to refer to the documentation before starting the diamond cutting. In addition, the rotation speed of the machine must correspond to the permissible speed of rotation of the diamond disk. For each diamond disc brand, the maximum permissible rotational speed may be unequal, and to find out the permissible speed of rotation of the disk, it is also necessary to refer to the documentation.

Incorrect installation and incorrect use of a diamond disk can not only reduce the efficiency of processing, but will also be due to the cause of damage to the cutter.

Before purchasing a diamond disk, get comprehensive information on the characteristics of the acquired equipment!

Today I would like to talk about the disks for the grinder, which is best to saw both the tile and porcelain stoneware. This video is primarily intended not for professionals, they, in general, everyone knows for a long time. And to those people who gathered on their own to separate the bathroom or a bathroom of some tile cutters, or some crowns to drill some holes in ceramics or cereral stars they do not have, but they have Bulgarian. And they can buy a disc that will cut without chipping porcelain and tile.

Also, this discs are very good to do as small holes, that and large holes in the tile, too, without any chipping, scaling. Very good to drink both "P-shaped" and "M-shaped" some designs in a tale, when all this is very close to the edges, where the edge remains literally 1.5-2-3 centimeters. And if the disk applies not the one that needs, then, as a rule, in this place, the tile and porcelain stoneware break.

"Wet cut" and turbo-disk

Now I will bring the camera closer and show which discs I have now in the presence. Now I have in stock two disks. This disc, which goes with notches, is called, as a rule, a turbo-disk or a disk for quick cutting.

But this disc, which is absolutely smooth and only around the edge is spraying, diamond spraying. This disc is usually sold in stores and it will be written "wet res."

There are still discs similar to this "wet res," but it will still have a slot along the entire contour. As a rule, it is written "dry res". Best of all the tile and porcelain stins saw the disk on which the "wet res" will be written.

That's the disk, if you see this, just written "wet-cut diamond cutting".

On this disk here is the inscription Turbo. He is already erased here, but you can read.

It is best to cut the tile with such disks. I used to do not use them. I was confused by what was written "wet res." I always thought that with water, you can somehow saw or somehow. But having tried once, I realized that and without water they can successfully saw and ceramics and porcelain stonewares.

This disk contains such attacks and attachments.

They begin to beat the enamel and make chips enamel. Same on dry cutting, where there are slots. These slots also beat the enamel and make chips. And if you cut through the very edge. Suppose you need to do some cutout from this edge "P-shaped".

So, as a rule, this is the edge of it will definitely break if you enjoy either a turbo disk or a disk "for dry cut." Since he will beat on the tile itself, there will be strong vibrations and necessarily the edge, will definitely sleep, and you will not work. What does not happen when the disk is sized with a "wet cut."

"Wet cut" is it for what is designed? Suppose, in the plotkores such discs are across, so.

And they pass as if through the entire array of tiles, and there I agree, water is necessary. Bulgarian you will drench only the moststs, so here is the edge. So that this disc is somehow heated or overheated, and it jumped into a tile. Well, it is hardly possible, and it is unlikely to happen.

The only negative is at the wet, when driving such, these discs are a big dusting of the room. That is, if you do everything in the apartment, you will have to go to the balcony. And if you do it in a private house, you will have to go. Marking all this to do in the room, and go out to cut into the street.

Real example of discs

Now I will go out and demonstrate the quality of the reserve of the turbo-disk, and the quality of the cut "wet cut."

To begin with, I will try to make a turbo-disk all this.

Now I will try to deliver the "dry cut".

This is the re-turbo disk.

But this is the cut "wet cut"

"Wet cut will be shall. Although it is a porcelain stoneware, it is difficult to cut it. Skoli, anyway, some, non-what, loops. Skoli, of course, there is. Now I will try to do the same on the usual tile.

Here is the usual tile wall.

Now I will cut it "wet cut", then Turbo.

Here is "wet res"

From this side turbo-cut.

"Wet cut" as you can see better, almost completely without chips and scaling.

Someone of course says that the difference in the cuts is insignificant, there is almost no it. To some extent, when the longitudinal cuts neatly cut and normal balanced Bulgarian, then it is so. "Wet cut" is still valuable that these holes are under the sewer, under 110 pipe, it is very close to the edges.

That is, from this side, 1-1.5 centimeters, from this 2.5 remains. This is the hole I cut the "wet cut." If I started cutting a turbo disk, then this or this edge, well, the tile (it was porcelain stoneware) he would still be broken. And the "wet res" it does not give vibrations on the tile and therefore the tile is normally cut down and is broken. The same applies to the cuts, if the letter "P" or the letter "g" is somewhere very, very close to the edges.

I hope this video for someone was helpful. Buy discs on which "wet res" is written. And when cutting a tile and porcelain stoneware will always be accompanied by luck. Especially if you drink some holes or something very close to the edges.

In order to save budget when laying a tile in an apartment or a private house, many prefer to carry out all the work on their own, especially since the instructions for conducting such works are more than enough. If everything is clear with the choice of design and the acquisition of the material, then it is often difficult to get difficulties with the installation process, since any room with a cladding will require a tile trimming and its fit for aesthetic species. Often, at home for cutting, an ordinary Bulgarian is used, and here you need a disc for cutting ceramic tiles or porcelain stoneware, not everyone knows.

The market offers a large number of Different circles, the price of which varies from 900 to 25,000 rubles. In order not to pay extra money for a certain brand and at the same time not to buy a useless blank, you need to know what types of products exist that they can be cut in and in what quantity.

Types of disks for cutting of porcelain stoneware and ceramic tiles

Many go to the store and try to buy a disk for cutting tiles or porcelain stoneware, believing that these are two different circles. In fact, the disk is selected not so much on the basis of the type of cutting material, but also considering the cutting volumes and the tool itself, which will be cut. All available samples can be divided into three main types, then consider in detail each of them.

Circles for wet cutting

The photo shows a diamond disc for porcelain stoneware for wet cutting, it is called solid. These same discs can be applied to the back of the tile in small quantities. The product is intended for wet cutting, that is, with the presence of coolant. It is used for electric stovetures and thanks to a solid cutting edge can do perfectly. smooth saw Virtually no chip.

In the presence of cooling with water, the cutting time is practically unlimited, which is ideal for cutting large tiles porcelain stoneware or outdoor tile, as well as to work with large volumes.

For your information. Such circles can be used when working with a grinder, but only for small sections and only on tile. In this case, the duration of the circle does not have to exceed 10-15 seconds, after which he needs to work on idling 20-30 seconds for cooling.

The diamond crumb is applied to the cutting surface of the disc with a silver solder, which, when heated, loses strength and spraying is rapidly wear out.

Important. Many often make a mistake when immediately after cutting tiles with a grinder, lowered a solid disk in a water bath for cooling. Sharp cooling leads to the appearance of microcracks on spraying and the product. The result of such actions becomes chips on the body of a circle, which often fly away during the cut and can damage the equipment, tile and injury.

Circles for dry cutting or dryorese

The disk for dry cutting of porcelain book or tile is called a segmented disc or dryore. The product does not need water cooling, since it has structural cuts from the edge to the center. These cuts are separated by the edge of the circle to segments, serve to cool the product during operation and compensate for the expansion of the metal when heated.

Designed to work on small circulation, perfect for a grinder or circular saw. It is recommended to use dryorese to cut a porcelain book or a large thick thickness tile. Suitable for small and medium work, but leaves chips on a glossy or glazed surface of the tile.

The photo below clearly demonstrated the result. The top plate is the result of a slice with a dry segmented disk, the bottom plates are cut off with a solid with a coolant feed. Such chips are permissible if the joints of the joint are hidden, but in the prominent section of the floor, such a quality of cut is not acceptable and hide them can only be a one-photon grout under the color of the material.

For your information. Like a disc for wet cutting, Sukhuxe also needs cooling. The cutting time is about 1 minute, after which the circle is cooled on idling Within 20-30 seconds and again you can start cutting.

Important! It is the dryrase that cause injuries in non-compliance with safety. The disk segments can capture the thread of the knitted glove, so it is recommended to use mittens from dense tissue. It is necessary to clearly monitor the position of the circle with a cut, its low offset leads to damage to the disk and the working surface.

Combined

Combined circles are the combination of a solid disk and dryness. This universal product is the perfect choice for household usebecause it can work both in dry and in cooling fluid mode. The advantages of the versatility of the product at the same time is its disadvantage. The disc will not be able to make such a pure cut as a solid analogue and cannot work for a long time without cooling as a typical dryhese.

Tip! For irregular use in an apartment or a private house, when laying tiles or porcelain stoneware in small rooms With a minimum amount of cutting, we recommend choosing a combined disk.

Important! Combined models more than others suffer from clogging effect when small tile grains are clogged in grooves and fall into diamond spraying. On other types of discs, this problem can be solved by turning the disk and changing the direction of rotation on the axis. Reverse rotation cleans the spraying and restores the cutting ability. Combined models typically have a given direction of rotation and turn it over the other side can not, it simply will not cut. In this case, use the usual silicate brick Or concrete, make several cuts and spraying will be cleaned.

What does the price of the circle depends

The cost of discs for the most part depends on the manufacturer, the size of the circle and its type. The most famous manufacturers of high-quality discs are such brands like:

Bosch.
Distar
DeWalt.
DRONCO
Emar vollrand.
Hilti.
Norton.
Kronenflex

Among domestic producers, it is worth highlighting such as:

Luganova
Interskol
Practice

Obviously, foreign manufacturers will cost more than domestic due to the cheating for the cost of brand and transportation. According to the results of independent testing of the manufacturers known in the market, it was the Bison that showed the results that significantly exceed the indicators of foreign models.

Also, the price of the disc affects the technology of spraying diamond abrasive on the cutting edge. The most common technologies is:

Savty solder. We mentioned these products above, where the abrasive chips solder to the edge of the silver solder. The technology is cheap and reduces the cost of models, however, when heated, the solder loses its qualities and the diamond spray is rapidly wear out. Consequently, the service life of the circle is small, but quite suitable for domestic use.
Geometric closure. In this method, electricity is used for maximum heating of the edge and the diamond sand is firmly poured on the surface of the circle. The service life of such products is significantly higher than the previous ones, the price remains within accessibility. Usually this method is used for combined circles that are suitable for dry and wet cutting.
Laser Sleaka. This is a very expensive technology and is applied to models. industrial use. This circle can be cut everything since white brick And ending with granite. The price of the product varies from 9,000 to 25,000 rubles.

Important! Today the market is filled with frank fakes under famous brandsSo buying a disc for dry cutting of porcelain books or tiles, pay attention to the price. For example, a circle from manufacturer Bosch. Or Hilti can no longer cost 900-1200 rubles. Make a purchase only in specialized outlets or brand offices.

How to choose a disc

Relying on the above information, we can already choose diamond discs for cutting ceramic tiles and porcelain stoneware based on our needs. The main selection rules are as follows:

If it is necessary to cut the porcelain stoneware or a large amount of work is to be done without the possibility of applying a cooling fluid to a cut, then it is better to prefer segmented dry cutters with deep slits or air-cooled holes.
If you need to work the usual ceramic tiles (not outdoor) with glazing coating, we choose solid cutters with diamond spraying for wet cutting. It is desirable that the thickness of the circle does not exceed 2 mm to reduce the number of chips.

Tip! In order for the slice to be as smooth as possible, choose a solid disk with a deposition strip slightly more than the thickness of the tile itself. The tile before sawing is desirable to soak in water, it is not required for porcelain stoneware.

With diamond cutting building structures Use two methods - "wet" and "dry". The difference between these types of work is quite simple - wet diamond cutting involves constant or periodic use of water to cool the worker. Firing Almas cutting does not require use in the working fluid process. It would seem that the difference is not large, but in practice it is quite essential. Let's analyze it in detail.

Advantages of wet diamond cutting

improving the resource intensity of the cutting body due to timely cooling;
improving the quality of work performed under conditions of high-level accuracy;
reducing the dust level due to the absorption of water jet of dust particles (the principle of the scrubber);
the ability to work with concrete at a depth of over 60 mm, with a brick - at a depth of over 84 mm;
reducing the period of work due to the continuity of the working cycle;
minimizing noise and workers vibrations cutting toolbecause Diamond drilling (drilling) takes place with the timely removal of the jet of the water of fragments and dust from under the cutting organ;
high efficiency of work due to high speed Their fulfillment and continuity of the technological cycle.

For the advantages of a wet cutting method have to pay some additional difficulties

Requirements wet diamond cutting

mandatory water availability in sufficient quantity:
when working with high loadthis may be a water supply, a large reservoir or natural reservoir (any source, including water pipes, should be at a distance of up to 50 m) with a certain amount of work, you need up to 10 liters per minute;
when performing one-time work with moderate loadthe diamond element is quite a small capacity with water or tank with a water pump;
removal technical water and sludge from the workplace with the help of industrial vacuum cleaners;
control over the leakage of water in the openings and cracks of the structure (in terms of the situation);
control over the non-payment of water on the current elements and the power supply devices;
the need to attract an additional employee to control the supply of water to a diamond disk;

Benefits of dry diamond cutting

ability to work portable tool away from the water source;
the possibility of working alone;

Disadvantages of dry diamond cutting

high dusting of the workplace and adjacent premises; The use of vacuum cleaners reduces dustiness, but does not allow to get rid of it completely
lower, compared to the wet diamond sharp, the level of accuracy and quality of work.
the inability to work with the maximum degree of load and performance due to the rapid heating of the diamond segment, which leads to a decrease in its resource intensity and the rapid failure;
restriction of cutting depth to 60 mm (for concrete) and 85 mm (for bricks);
the impossibility of rapid removal building garbage from under the cutting body, which increases the duration of the working process of cutting, increases the level of noise and vibrations;

In this way, wet cutting is a predominant methodAlthough its application is associated with additional efforts to organize work, namely, it is necessary to take care of the supply and removal of water. However, if we are talking On sufficient work, then additional efforts for water supply are not so burdensome in comparison with the costs of dry cutting method. In other words, it is easier to take care of the supply and removal of water, rather than to cut the price of great effort and time.

In general, the wet diamond cutting method is more preferable, therefore, it is always used where large amounts of work are required, high depth and accuracy of diamond cut.

Dry diamond cutting has a practical meaning when manual workthat do not require highest level Accuracy and deep cut. Either by an exceptional principle: if providing sufficient water supply is simply impossible.
