How to cut metal without sparks

At all times, from the very moment of its appearance, the metal was surrounded by various problems: from its extraction to subsequent processing. This problem was especially aggravated during the period of the industrial revolution, when an increasingly increasing pace of life encouraged production to adapt to it and look for such processing methods that would allow the production to be competitive in the conditions of a market environment. Many, especially those who have an age is quite middle.aged, could make various gas cutters found in abundance in our cities, which, as a rule, were used by plumber and utilities, for the repair and bringing of heating pipes. Picture Source: www.metistr.ru The problem of cutters, however, is that for cutting metals using this method, the use of expensive and dangerous gases is required. In addition, these gases must somehow be transported, in a certain way to store. Picture source: Ballon74.ru All this makes the cutting process quite problematic. However, there is a much more high.tech and economical method, which has spread widely (especially in domestic plan), recently. It is about him that we will talk in this article. Gas cutters, in their essence, work according to the same principle: the metal heats up in the jet of the flame of the gas cutter, after which it partially burns/partially blows out, from the cutting zone. A particular case of this cutting method is “cutting with an oxygen spear”. The method is that the tip of the oxygen spear (which is a steel tube), is heated by a burner, after which the oxygen supply opens. Oxygen coming right inside the “spear” allows the tip of the spear to actively burn, due to which there is a constant maintenance of the temperature in the contact of the spear contact and the cut workpiece. When using the oxygen spear method, it is possible to make holes in metal blanks, up to 2 meters thick. At the same time, the spear itself is actively burning and its consumption is up to 25 diameters of the hole that is made with its help. In addition, an oxygen spear is often used not only to make holes, but also to cut the workpieces of large diameter. The process itself looks more than impressive: however, having read all of the above, the reader will have a logical question: if any work on making holes, or cutting metal is so energy.intensive and costly in terms of gas consumption, how can this work be done without precious gas costs? For this, the plasma cutting apparatus is useful. Despite the fact that the household apparatuses of plasma cutting are distributed recently (the starting point can be considered 2006, when portable devices appeared), as a metal processing tool, they have been known for a long time. They can consider the starting point of their history in 1929, from the moment the fact of the ionization of gases, in gas.discharge tubes, physicists from the USA. and.Langmur and l.Thin. And since the middle of the last century, plasma cutting, based on the opening of these two physicists, has spread widely for the purposes of metalworking. The essence of plasma cutting is that compressed gas is supplied to the electric arc, having a pressure of several atmospheres. After purging the arc. gas, it acquires a temperature of up to 30,000 degrees Celsius (and more, if additional water vapor is used) and turns into plasma.

Здесь мы подошли к самому главному: при работе аппаратов плазменной резки может быть использован обычный атмосферный воздух!

Именно это качество и делает плазморезы такими экономичными и малопроблемными, по сравнению с классическими газовыми резаками: ведь не используются никакие опасные газы, требующие аккуратного обращения и соответствующего хранения, и в качестве рабочего тела выступает обычный воздух! Конечно, использование воздуха это только один из видов плазменной резки, в зависимости от целей могут применять как азот, так и аргон, и другие газы. Одним из самых важных элементов аппарата для плазменной резки является плазмотрон — именно он отвечает за то, насколько эффективно и какие именно типы обрабатываемых изделий будут доступны конкретному устройству. С электрической точки зрения (зажигания дуги плазмореза) плазмотроны бывают 2 типов: прямого действия и косвенного действия.

Direct plasmores acts on the principle of ignition of a high.frequency pilot arc, which allows you to “blow out” a plasma stream that concerns the processed workpiece. After the plasma touched the workpiece, the pilot (setting up) arc goes out and the main one, which already allows the workpiece (plasma is an electricity conductor, is practically no different from the metal itself, so the arc burns directly “through” the plasma). In plasmotrons of indirect type, the setting of the arc occurs due to the discharge between the cathode and the nozzle. Theoretically, plasmotrons of this type allow you to process the blank of the non.metallic type.

Consumable parts for plasma cutter are nozzle and electrode. Due to the fact that these parts are quite inexpensive, their replacement is not any problem. Their service life is quite individual-the network appears on the numbers in 500-600 cuts, or 1 set per 150 meters of cut, etc.D.

Than cutting corrugated board: advantages and disadvantages of various tools

To date, the profile flooring of popular material in construction. Therefore, quite often questions arise about the possibility of independent cutting of sheets, the better to cut corrugated board and ways to prevent corrosion of their edges.

In this article, we will analyze the advantages and disadvantages of tools for cutting profileists known to the masters.

Corporals are steel sheets covered with zinc and a protective color layer of a polymer, easily bending and resistant to deformation, protecting steel from destruction and retaining color resistance.

In its appearance, it resembles slate, and has alternating trapezoidal, rectangular bulges and cavities, different widths and depths. Metal for the production of corrugated board has a thickness of up to 1 mm, which is the peculiarity of the cut of parts of the required size.

Manual power tool for cutting corrugated board

Most popular, practical and quick in use are power tools. Corner grinder, electrolobesian, electrician and manual circular saw can be applicable for cutting the Chishminsky profiled sheet.

Modern construction is almost impossible without the use of concrete. To obtain high.quality concrete, it is necessary to choose the right concrete mixer.

Here you will learn about how to choose the right drill for construction work.

By link-http: // vse-postroim-sami.RU/Equipment/Power-Tools/2176_kak-Vybrat-Shurpovert/-detailed information on choosing an electrical screwdriver is presented. This article discusses the types and main characteristics of screwdrivers.

Is it possible to cut corporal grinding corral?

A manual angular grinding machine, and popularly called a corner grinder, a widely used tool for cutting different metals, and corrugated board is no exception.

I do not advise you to use a corner grinder, since high temperature effects on the polymer layer have a negative effect on a high temperature effect on the polymer layer. Despite this, some masters and profile sellers use it as the easiest and most practical cutting tool.

So whether it is possible to cut corporal grinding corral? And how to cut corner grinder corrugated board, with minimal damage to coating?

Attention! The main rule that must be adhere to when the profiled sheet is correct is the correspondence of the diameter of the cutting circle with the height of the sheet of the cut sheet.

Cutting a small corner grinder of corrugated board with deep relief, the sheet in the lower corners will be difficult to immediately cut. It will have to turn it over to the other side. It is better to opt for an angle grinding machine with the largest circle diameter and the thickness of the disk from one millimeter to 1.6 mm, with teeth of carbide materials.

It is important that the corrugated board does not touch the ground or the surface of the table where the cut is performed. Dust may rise or easily deteriorate the desktop. The use of corner grinding grinding for cutting a sheet in experienced hands of the master allows you to cut the details of the necessary geometric shape.

The use of an abrasive circle during operation harms the protective coating of a profiled sheet. The fact is that at the edges of the cut, the abrasive circle greatly warms the metal. This leads to the burnout of zinc, polymer coating and other layers. In addition, sparks falling on a profile sheet can break the protective coating. This reduces the service life of corrugated board.

As an option, an abrasive disk can be replaced with a disk for cutting aluminum. But it is better to use a special disc for a profile cutter. The edges of such a cut will be straight and neat.

Electric

With proper accordance with a sheet of corrugated board with a tool, an electrolobian is a completely suitable option. It is better to use a professional class electrolobian, since the domestic class tool is low.power and sheets with a thickness of more than 75 mm is almost impossible to cut. The optimal depth of the leaf wave for a household electrolobian is about 20 mm. He does not burn the protective layer, but the metal is tearing.

Professional class electrolobesis capable of cutting profiles C8, the properties of which to the taste of purchasers.

There are some disadvantages of this tool for cutting corrugated board. The cut sheet must be installed vertically, respectively, it is necessary to support the already cut strips, for which several assistants will be needed. Often, saws break during work.

Attention! The opinion of experienced craftsmen is not the most suitable option for a profiled sheet cut.

Electronics. scissors for cutting corrugated board

If there is no need in even edges, then electrician is the best tool for cutting corrugated board. They cut metal quickly, a layer of one millimeter. In addition, you do not need to make a lot of effort, the metal cut passes automatically.

Schlotovo electrician for cutting a profiled sheet are most suitable. It is considered a universal tool that can make neat cuts, without curvature and deformation during figure cutting.

Curtain scissors cut the material according to two parallel straight lines, while there is no need to bend the profile. Such scissors for cutting corrugated board cope with steep turns perfectly. For greater convenience, the handle rotates perpendicular to the cut line. In addition, you can drill a hole in the middle of the profiled sheet and cut in the desired direction with cutting scissors.

Upon completion of the edges of the cuts, they are even, without burrs and do not bend.

How and how to cut a stainless steel tank without sparks?

How and how to cut a stainless steel tank without sparks? The tank on the second floor of the country house, it will not fit into the window, put it at the time of construction of the house. It must be cut into parts if corner grinding. then sparks are possible and suddenly a fire.

I have a saber saw. I can’t call with confidence a thinking head from the shoulders and hands, but there are sparks! ))

The places nearby in the rez can, even you need to cover. If it’s completely reflected (it happens, I know by myself). Put a partner next to the fire extinguisher / water bucket.

And then watch in this place for another 6 hours. Of course, this is not welding, but the likelihood of a fire that if the saw from the piece of scale is great, and the tree does not burn right away, it smolders.

I am in my life that only and where I just did not saw. He sawed even inside the governor’s Mercedes in the finished finish, lol) does not really seek to light up, it is worth saying, you just need to observe a little care. Most importantly: put the barrier in the path of sparks so that they do not fall on the surface of glasses and furniture. Even glass easily spoils with these sparks. And remove flammable materials (blankets, liquids and the like). And so, in the vast majority of cases of a piece of non-combustible rag (tarpaulin) and an assistant “controller” will be enough.

By chance. It is better not to repeat) although in general I agree that it is very difficult to set fire to the sparks, and in this case you can calmly cut a corner grinder, put a bucket of water nearby for any.

Trampers and fire extinguishers. This is of course good, but I agree with one, the fewer sparks, the less likely the fire. I sit down one thing that no land “firefighter” knows, and the fire inspector, too, on the ship after the welding work of the shift at the site of welding work lasts 6 hours. And this despite the fact that there is no tree around the tree, only iron and paint. In fact, when working with a corner grinder, not so much sparks are dangerous, they are too small, quickly go out and often enough a piece of thick fabric or simple cardboard to exclude their distribution where it is not necessary, larger pieces of metal are dangerous. And if we take into account that the aluminum is soft, the probability of aluminum leaks, failure of larger pieces and their sputes are not on the path of sparks is quite large.

How to learn how to cut a corner grinder without sparks: 5 tips from pro

Pila-ugly grinder is one of the most common types of power tools around the world. That is why it is worth buying a saw-ugly grinder extremely carefully, since this tool is simply unique- it is multifunctional, easy to use, reliable, economical, safe if you use it wisely.

But most often with a saw-ugly grinder is used for grinding and cutting materials, and there is a lot of sparks. Although they do not cause a lot of trouble if you protect your eyes with special protective glasses, in some cases it is simply necessary to get rid of sparks.

For example, when grinding or cutting metal parts is carried out next to gas cylinders, it is better not to allow sparks to formation. It is very important to understand that the corner grinder is an extremely common tool that helps builders and workers carry out all the work with metal without difficulty. You need to work with this tool extremely carefully and you need to be able to defend yourself from the lawsuit formed.

Five ways to avoid the occurrence of a lawsuit when working with a corner grinder

In fact, despite the fact that the problem with the sparks from the corner grinder is quite common and unpleasant, getting rid of them is not so easy. The reason for the occurrence of sparks is the formation of small particles of metal, which are cut off from the working disk of the corner grinder, and from the metal material, which polish and cut. Thus, getting rid of sparks is practically unable to get.

But there are several tricks that can help in some conditions get rid of all sparks or most:

• The main way to reduce the number of sparks generated during the operation of the corner grinder is to lower the temperature in the epicenter of contacting the working surface of the tool with the processed material. In this case, you can either ask someone to pour water to the working grinding circle of the corner grinder, or buy the existing models of the saw-upper grinder with the ability to cool the working surface with water with water. In this case, you can increase the service life of the cutting or polishing circle of the tool, and at the same time avoid the formation of sparks.
• You can also use ordinary machine oil, which will help reduce the temperature on the working circle of the Uglovy grinding saw and at the same time the number of metal microparticles formed will drop sharply.
• You can try to use a saw or a grinding circle for a corner grinder made of ceramic especially new material. In this case, you can increase the life of the working tool, and the number of sparks will decrease sharply.
• You can also use home.made shields or in the kit for tools they must be there that will not save from sparks, but direct the shields their flow in the right direction.
• The problem of the formation of sparks during cutting or grinding with a saw-ugly grinder is that very small metal particles with high acceleration speed and having high temperatures can cause harm and health of the employee and others. That is why recently special “cooling powders” have appeared, the role of which is reduced to a decrease in temperature on the working disk of the corner grinder, and to bind the particles of the metal, and deprive them of high speed and suppress the formation of high temperature. Such powders can be poured onto the grinding circle of the corner grinder itself, and on the processed surface, the number of sparks will greatly decrease.

Thus, we can confidently say that measures to reduce the number of sparks when working with a saw-ugly grinder are quite effective, and if you remove the latest high-tech, then dealing with excess a lawsuit when working with this common material is extremely simple.

Areas and features of non.bending cutting

The need to cut metal and cut pipes of various diameters gave rise to many tools and technologies.

Separate part from the metal sheet, parts, pipes can be [cutting methods], most of which are associated with the emergence of sparks and heating the material and tools.

Uncondeous and non.infinite techniques allow you to carry out operations with minimal heating, including on existing pipelines with combustible substances.

Non.bended cutting of pipes and metal without sparks suggests that the process will occur under fairly strict conditions and restrictions associated with the temperature regime and the probability of sparks.

Technologies were developed for special occasions when the temperature should remain within certain limits, and particles of metal from the tool and material cannot heat up from intensive effects.

The need for unlimited and non.bended processing

Methods of cutting pipes and cutting metal are based on the interaction of the tool with the material, which is almost always associated with the release of thermal energy. This is far from always complies with the requirements for the result:

• It is necessary to make the incision so that the edges of the blanks (parts) do not heat up and do not change the properties of strength and plasticity;
• It is required to avoid the appearance of sparks that occur during the operation of a sawing and percussion tool;
• It is necessary to abandon the use of a tool that exerts strong pressure on the metal, leading to its heating;
• The pipe is filled with combustible or explosive mixtures, it remained unsteady oil products or other igniting substances, work is carried out in conditions of room with high fire safety requirements.

To understand the mechanism and choose the method of flaw (unlimited) cutting, you should understand how the separation of fragments of the metal occurs with different tools.

It is important to know: how to make a laser cut on metal with your own hands?

The reasons for the appearance of sparks and heating when cutting metal and cutting pipes

The temperature increase at the cutting site is associated with the mechanical contact of the tool with the metal or the use of a heating tool.

The work of a saw and a sawing disk is to apply frequent strokes with teeth or irregularities on the surface or edge of the workpiece. Each blow causes rapid heating of metal particles flying away in the direction of rotation of the tool. At the same time, the contact zone and the tool itself are significantly heated, and the flow of sparks can lead to fire.

[Plasma cutters and installations] direct the stream of ionized gas to the metal, which is in any case associated with local heating.

Shock cutting and cutting, depending on the intensity and hardness of metals, lead to the release and transformation of energy. This gives the effect of warming up, and often a passing output of sparks.

[Gas oxygen and acetylene cutting] refers to fire methods, since the effect on the metal has a jet of burning gas mixture. This is not only an open flame, but also a significant heating of the workpiece.

The most safe from the point of view of heating and lack of sparking can be attributed to scissors, [hydro.carbonated technology] and slow treatment with roller machines.

It is important to know: overview of the varieties of metal saw

Fire and high.temperature methods

It is worth paying attention to the fact that the requirements for technology can be different.

In some cases, moderate heating of the material and tools is allowed, but the flawless technique involves the use of only mechanical and hydraulic devices.

Laser, gas, plasma and partly electrical tools can be equated to the group of fire. they cause heating with an intensity sufficient to ignite oxygen or combustible materials.

Machines for non.bending pipe cutting

A machine for non.bending cutting in industrial conditions is a roller or chain unit that covers a pipe or blank and acts on it with a rotation of sawing devices with low speed and quite high pressure. Thus, the effect of either the separation of the metal due to the achievement of plasticity along the cutting line, or the gradual removal of the metal layer to the final through cutting, is achieved.

Furious cutting devices and inserts into pipelines are available for manual use, with mechanical strengthening, with pneumatic or electric drives. Industrial machines can be detachable or inexpressible. the first is closed on the pipe, through the second pipe they pass.

On large diameter pipelines, complex chain devices with an electric drive are used. For cutting thin.walled pipes, it is best to use roller devices.

The advantages of this technology include the possibility of obtaining a flat cut without deformation and roughness through the end.

Metal carbide. We work without sparks

Get to know! Chards for cutting metal

The components of all carbide disks are the base and cutting teeth. The number of cutting segments begins from 24 to 100, the larger the number of teeth, the faster the workpieces occurs.

A distinctive feature of segments is the presence of special attacks, which play the main role in the cut. Alloys of cutting teeth can be different, basically it depends on the manufacturer.

In most cases, tungsten.baltic alloys or tungsten carbide are used, cobalt. The carbide cutting segments are attached using soldering from electrolytic copper with the addition of nickel alloys.

On many disks models, you can see the slots made to dispose of heat, which extend the service life of the carbide disk.

Such discs are used on pendulum, end and hand.handed drops for metal. Of course, there are friction piles, which can also be attributed to carbide, but this will be the topic of a separate article.

Speaking about the distinctive characteristics of the carbide disks for the metal, then for each type of metal its own disk is used. There are aluminum discs, wheels for high-carbon steel, for low-carbon steel, for thin leafy metal, for sandwich panels, for stainless steel.

The most important criteria when choosing are: the diameter of the disk and the diameter of the landing hole. The most popular diameters are from 200 to 355 mm, here the most important thing for which tool do you need a disk. The situation is also with the landing holes, their range from 20 mm. (for manual disk saws) up to 30 mm.

(for pendulum saws). The number of teeth on the disk is directly proportional to the speed of cutting the material, when choosing you should know this.

You should always check the required number of revolutions, which is indicated on the packaging or on the body of the disc with passport data, the tool used.

Pluses and minuses of carbular disks for metal

I would like to note right away that there are a lot of advantages compared to abrasive disks in carbide, but the price of equipment and the discs itself is holding back the popularity of their use. Give about everything!

• The accuracy of the cut. In order to observe accuracy with a cut of metal blanks, a carbide disk on a pendulum saw is one of the best options for work.
• The speed of work. You will be surprised at what speed the carbide disk saws.
• A huge resource of the disk. On average, the resource of the disk 5000 cuts. Compared to abrasive, it is immortal.
• Lack of harmful emissions. When working with an abrasive in the working area, a cloud of small particles is formed, which negatively affects human health.
• The metal does not heat up. After you cut off the workpiece, you can safely take up it, it will be cold. The main plus is that without exposure to temperatures, the properties of the metal do not change.
• Price. The cost of a carbide disk is ten times larger than abrasive. At home, with rare use, such a disc will not pay for itself.
• Metal loss. Since the disk is thicker than abrasive, it is worth considering that the fishing line for the trimmer of the cut will be thick.
• Afraid of rust. If you decide to saw metal with rust, remember that the disk will wear out faster.

When we concluded all of the above, we can say that the carbide wheels belong to more professional consumables. They have less disadvantages than competitors, but the price makes them inaccessible to domestic use.

Manufacturers and prices

The scatter of for carbide.saving wheels for metal is huge, the main thing is to decide for which tool and which metal you will cut and based on this make a choice for steel from 3000 to 20,000. Manufacturers are also a huge number.

Each company that produces disk or end saws necessarily produces consumption to them, or buys products from third.party manufacturers and sells it under its own brand.

It should be borne in mind that there are no single standard for the landing holes and it is beneficial for manufacturers to make them different, so that they are also consuming to their instruments.

Talking about which discs are better pointless and I will not list the brands of large manufacturers to you. I will say from my own experience that I used Hilti discs and an attack, the former cut better, but the price for them is larger. Reading reviews on the Internet, I heard a lot about the production disks of CMT Orange Tools. When choosing discs, pay attention to it.

Protection against angular grinding sparks and how to completely get rid of them

Corner grinder without sparks. is such a recommendation possible from professionals

For everyone, the usual angular grinding machine is used for dismantling, as well as for cutting different materials.

Its scope is incredibly large, and this is a big plus, but the danger of injuries is a significant drawback. But we know how to remove it and tell you what protection from the sparks of the corner grinder.

Please note that the greatest danger is precisely sparks from the corner grinder, as well as the likelihood of pinching the disk.

Why sparks begin to fly

Metal disks for corner grinders rotate at an incredibly high speed, and during rotation the cutting material begins to heat up to high temperature.

The smallest particles of metal, stone begin to heat up and form sparks during friction. The stream of sparks is able to pose a greater danger to the operator, as well as for a nearby people and objects. Sparks are capable of burning, causing a fire of textiles or dry grass.

Safety precautions when working with a corner grinder

In order to reduce the likelihood of injury to himself and others, the master needs to follow certain recommendations. In no case should you forget that in addition to sparks, there may be a pinches of a disk.

In this case, the tool can tear out the operator from the hands, and where the tool with disks that rotates at high speed will fly, it is very difficult. The consequences of such an accident can be chopped pieces of flesh and so on.

Interesting fact! The corner grinding machine was invented only in 1954, in Germany, and the colloquial name of the “Corner Schilifmashinka” tool appeared in the USSR in the 1970s, when the first copies began to be brought. At that time they were produced in Bulgaria, and only in the countries of the USSR were corner grinders called corner grinder.

• Side placement of the adjustment handle. The handle should be located on top, not lower or from the side, but vertically. In this position, the master will be able to provide a dense and strong capture, and will be able to protect himself, as well as people from the consequences of “biting” the disk. In addition, sparks in this case fly aside, and this also provides safe work.
• Direction of the disk. When cutting in the direction of himself, the master will not fall under the stream of sparks, and therefore, usually beginners have the device in this way. But experienced masters know that the casing perfectly protects from sparks, and that sparks are not as terrible as the clamping of the disk. With a cut from itself, a fixed corner grinder will fly just into the master, which will be a guarantee of injury. During sawing on itself and a slightly turned disk, the corner grinding machine during the “snacking” will fly away from the master, to the ground.
• The location of the material during cutting. If the metal sheet, fix the pipe on both sides and saw between the mounts, then you will make a mistake. Such an action often leads to the fact that the disk jams at the end of the process. For this reason, one end must be on weight, and at the end of the cutting the process of “compression” occurs, and the disk will not jam. In this position, sparks from the material go away from the master.

Tighten the nut. Tighten the nut is only in vain to waste time, because in the process of performing the work the bolt will be delayed to the required level, and at the beginning of the work, there is enough standard twisting of the nut with your hands.

Keep in mind that if you pull the nut with a key, then it will be difficult to unscrew after it. The launch button of the corner grinding machine is pressed only with the free drive of the disk, which means that you can not immerse the saw in the cut before you run the working cycle of rotation.

We offer to consider a method that will leave your corner grinder without sparks.

Corner grinder that does not spark

• So, you will need the angular grinding machine itself, an adhesive gun (exactly the one that melts silicone rods) and any non.combustible material.
• You need to apply silicone to the protective casing of the device, only a couple of points, because there is no need to glue tightly.
• In the role of an impromptu shield, you can even use a insole from roller skates to protect (which will become an excellent material for the manufacture of bearings), but it can be any other non.combustible material, for example, a piece of sandpaper, leather, a thin sheet of tin.
• Next, glue this material to the silicone to an already installed protective casing, and this will be the second level (with your own hands, a mudguard, or to be more precise, sparkling).

Next, you can continue the standard work, but now you can’t worry that the sparks will set fire to something. And even more, such a protection of the way to save from fragments, as it is a kind of continuation of the protective casing.

For short.term use of the device, such a modification may not be required, but if you need to cut a lot of metal, then the sparkle will be an excellent protection. When the sparkling ceases to be necessary, it will be possible to just rip off silicone glue, fortunately, the silicone is separated from the metal without problems.

In the video, the process of cutting corner grinding:

I hope the viewing was useful. I cut a large diameter here and spent only three minutes on a sharp, it is natural that the time spent on cuts of pipes with a diameter of 15 to 25 millimeters will be much less. When working with a corner grinder, always be with glasses. this is a prerequisite for the safety of your health.

So, dear friends, feel free to use it in work and let you always accompany you success.

One spectator, in the name of Vladimir Temlyak, wrote: “They show all crap only to earn extra money”. I wonder what is my earnings here? The last commentator, under the nickname Jumatatu Ta, threw a couple of links to the photos of mutual people. And then it dawned on me that many “roller” spectators are ordinary inhabitants, moreover, frightened by horror stories on the Internet. The next line is for them:

Dear “sympathetic”, maybe this is a secret for you, but daily a million people use a corner grinder (corner grinder) in the work of work, and five hundred thousand of them work without a protective casing installed on it.

For these guys, the video was shot, I wanted to introduce them to a 1.2 mm thick disk.

But I have already touched me these diesella and therefore decided to study what is on this issue on the network. What was my amazement for reading sites located in the top of the search engines: a lot of articles written about corner grinder with copywriters. Who is it? And I will explain, a copywriter is a person who makes a living by writing articles, that is, he is given a set of keywords (in our case, an angular grinder, a cutting disk, an accident), they say that the article should contain at least 2-3 thousand signs (a sign is a letter, a symbol, a gap, etc.P.) and he is slamming the article. With the same success tomorrow, he writes about God’s cow, and the day after tomorrow about spaceships, and a day later about the benefits of the mixture “Turboshem”. I clearly explained?

What can write, for example, in the news release a correspondent? Of course some stunning sensation, oh how they love phrases: “Two staircases in the entrance were flooded with blood” and the like. Never, no one in the news will tell that the Moldovan, or there is an Uzbek, or Russian, put a circle of the wrong diameter on the corner grinder but in vain!

No, do not think, I did not have in my thoughts to “beg” the seriousness of working with this tool, but this is just a tool. a hand tool. Let me remind you once again: a million people use it daily, and five hundred thousand of them are exploited without a casing.

Let’s go from another side. Supposedly taught to use power tools in professional schools. Remember who studied there, what you were taught there? TB (safety precautions). almost a abusive word, at sixteen. seventeen years old, the head is clogged with another. And who studied the operating manual after the purchase of the tool, so that from the crust to the crust? There are of course such guys, but there are few of them. believe me, already. For example, I got a job at the company, which is engaged in the dismantling of old, and subsequent installation of new water supply, heating, sewage systems, as you think I explained the rules of use? That’s right, no one showed the power button and demonstrated how it cuts! Everything! You can’t imagine how I was at first afraid of a corner grinder, and no wonder, you hold it in your hands, and she strives to break out. Experienced locksmiths only giggle, and your hands are trembling. How many such new?

And how many “d, artanyans”, which the sea is knee.deep, how much is among our brother. go away, I myself know, I can do it myself? Exactly, there are enough of them too. So they, the heroes of the reports are horror stories, I listed them to you.

That’s why I decided to supplement the article, but previously still selyed reviews, Комментарии и мнения владельцев on specializing forums. Yes, yes, I met the guys directly encountered every day with this beast, but they also throw links to each other in the same photos of the unfortunate people crippled by the indistinguishability of people. I put such unpleasant pictures below, I don’t want to, but without it in no way. For all the seriousness of the recommendations that I will continue to continue. I’m not in “turquoilies” I suggest playing.

Well, dear, how feelings? I also have shock. Believe me, these are not the most terrible pictures. I will conventionally call their picture one, and two pictures. Then I will explain what served as what happened. So let’s move on to the point:

How to cut a corner grinder?

Transportation of disks; 2. External disca of the disk; 3. The diameter of the circle must correspond to the permissible corner grinder; four. Compliance with the maximum permissible revolutions; 5. Use of the disk for its intended purpose; 6. The use of a “non.fresh” disk is not acceptable; 7. Inspection of the workplace; eight. Hanging parts of workwear; 9. Position with a cut; ten. Provide for the rebound of the tool; eleven. Direction of rotation of the disk; 12. Try not to deepen the edge into the depths of the cut; 13. Adhere to a given trajectory of disk rotation; fourteen. Turn off the corner grinder when changing the position; fifteen. When changing the disk, de.energize the corner grinder; 16. Grind only the disk provided for this; 17. Use a protective casing when working; eighteen. When working with a corner grinder, always be with glasses.

Consider each of the listed points, and remember that each of them is important at least the other.

Transportation of disks.

Typically, the entire tool is in one box, without fail, take a separate compartment for disks that does not allow strikes on them. Which can lead to damage not noticeable by eye.

External disk examination.

Before installing, make an attentive visual examination of the disk for the presence of a broken, you can slightly beg, and if it is broken, it will immediately be revealed, of course, such a disk is not allowed to use. If there are potholes on the cutting edge, it is better to reject, the cost of the disk is penny, and the consequences can be the most deplorable.

The diameter of the circle must match the permissible corner grinder.

The corner grinder indicates the maximum allowable diameter of the circle used. Never set a circle more than indicated in this meaning.

Compliance with the maximum permissible revolutions.

Both on the corner grinder, and on the very cut.out circle, there is a marking pointing to the maximum permissible turnover per minute. On a corner grinder, this is the value of the spindle rotation, on a circle. at what maximum speed it can rotate. In the first picture, the result of non.compliance with this rule. That is, if the forty rotation of the spindle is 10,000 rpm, then the circle should be equal or large, but in no case no less.

Using the disk as intended.

What is meant here? The fact that the disk intended for cutting metal is not permissible for cutting stone, glass, marble, tiles, porcelain tiles, for this there are special discs with diamond tips on the teeth. And vice versa, a diamond disk is not permissible to cut a metal pipe. It is also not permissible to install various mills on the corner grinder, saws. a visual consequence in this picture: and in a conditionally named second picture, the man sawed the tiles with a cutting disk for metal, in addition, without a casing. I don’t do tile work, so I don’t know what speed of rotation of the cutting disk should be when cutting the tile, on the forum one of the specialists indicated that no more than 3000 rpm, and by itself a special disk for this. What led to an unfortunate man who was neglected by this rule themselves.

It is not acceptable to use the “non.fresh” disk.

What does that mean? I found, for example, a disk in a garage or under the bathroom, or where. break it and throw it out, that’s the whole fairytale, not to jerk fate for anything!

Inspection of the workplace.

Also not unimportant nuance, cutting out pipes in the apartment of workplaces, in the toilet, in the bathroom, in the kitchen. Inspect the first. PARTOVO for the absence of hanging wires, ropes. It is no secret that people like to be tied to pipes, so you need to remove it away from sin, you will be intact. Some kind of crap for a rotating element of a corner grinder, it will fly out of her hands and you won’t have time to blink.

Hanging parts of workwear.

I think it’s not worth it to explain what can be fraught with. The buttons are fastened, the holes are sewn up, the fringe on the legs, no sleeves.

Position with a cut.

Clear stump, when dismantling, you try to get by the least amount of cuts, but never, you hear never being on the trajectory of the disk, no matter what you are, you will not provide for everything, there are all sorts of cases. The next point to the place.

Provide the rebound of the tool.

Just in case, provide where the tool can fly off if it “bites” the disk. And if you are not sure, do not do the cut to the end (the pipes are often in suspense), leave a small jumper, you can always break the gas key with the help of a gas key. Do not relax, at the end of the cut, hold the corner grinder tight.

Direction of the disk.

Who cuts like, a matter of habit, and sometimes otherwise there is no way. The video clearly shows that I cut. sparks on myself. This is not very convenient, but there is much less likely that the disk will “bite”, and if it “bites”, then the corner grinder will fly from the cutter, and not on it. So think about the amenities in this case.

Try not to deepen the edge into the depths of the cut.

Well, here regarding the pipes of large diameter, do not deepen the cutting edge more than necessary, less likely that the disk will break.

Hold the specified drive trajectory of disk.

This condition is unequivocal to execution, no changes in the trajectory of rotation, that is, how to cut, in the same position it is necessary to finish the cut. And one more point, if there is no professional skill, you should not try to get into an unfinished car for a second time, and in no case do not insert a disk and then turn on the “start”, don’t go straight to the grandmother. the saddle is waiting.

Disconnect the corner grinder when changing the position.

I made a cut, you need to change your position, turn off the corner grinder, wait for the stopping of the disk rotation, only then move. Took a different position, made, turn on the angular grinder. This is the only way, not otherwise. If health is expensive, otherwise you can stumble.

When changing the disk, de.energize the corner grinder.

Be sure to remove the fork from the outlet, install another disk. It is not appropriate to be lazy here.

Grind only the disk provided for this.

To cut the threads, it is necessary to remove the chamfer along the edge of the pipe, often “slop” to install the grinding circle provided for this, and in vain, pulling it with a cut.out circle, you will become thinner, which is not good, fraught with the same “vulgarity” for pieces.

Expert view: how to cut corrugated board?

Even if you ordered a corrugated board of the required length, during the installation process, you may need to cut the sheet. Sometimes a profile must be shortened or “adjusted”: for example, in the places of adjustment of the roofing material to the chimney. If you mount a roof or a sophisticated fit, you may need to cut the corner of the profiled sheet.

The question arises: how to choose a suitable cutting tool? We formulate the general requirements for it. A curriculum cutting tool should:

• cut a profile without overheating of metal, do not burn polymer and zinc coatings. The profile is a “pie” of several layers: a steel base covered on both sides by zinc, soil and a polymer layer (on the front side) or a protective coating (from the inside). Each layer performs a certain function: it protects the steel basis from corrosion, provides a professionalist with aesthetic appearance and others. If one or more layers are burned out, this will affect not only the aesthetic characteristics of the corrugated board, but also the functional. the steel base will be subject to corrosion;
• Do not form sparks during cutting. Sparks from the abrasive disk can damage polymer and zinc coatings. We indicated the consequences of such damage in the previous paragraph;
• leave a clean fishing line for the trimmer of the cut, do not deform the edges of the profiled sheet. Otherwise, the resulting “burrs” will need to be bend, and the crushed edges. straighten. This will require significant time spent;
• Do not melt the edges of the profiled sheet. Otherwise, this will lead to damage to the protective and polymer layers along the edges of the sheet and, as a result, to the occurrence of bromatic corrosion.

Consider which electrical and manual tools are optimal for trimming a profiled sheet, and which is prohibited to use.

Attention: Do not forget to process the seats of the sections with repair enamel.

Is it possible to cut corrugated board with “corner grinding”?

The profileist is strictly forbidden to cut this tool for three reasons:

• Spectacular sparks that fly out from under the disk during work harm the decorative-protective layer. They fall on a polymer coating, burn it and zinc. In places where sparks got, corrosion may appear.
• The abrasive disk saws a professionalist due to friction. As a result, the metal heats up, under the influence of high temperatures, the polymer and zinc coating along the edges are burned out, which leads to the occurrence of bromatic corrosion.
• The abrasive disk leaves the “torn” edges.

So: “Corner grinding” can be quickly cut, but it will become unsuitable for use. Therefore, the answer to the question “How to cut corrugated board“ corner grinding ”” is simple: no way.

Whether the cutting of corrugated wood is permissible with a disk saw?

Cutting corrugated board using a disk saw, even if you use a diamond disk with small teeth, is not the best option. This tool cuts metal due to heating; The disk melts the edges, and with them. zinc and polymer coating. Thus, the edges of the sheet are again unprotected from corrosion.

There are no sparks in the process of cutting, which burn polymer and zinc coatings. But due to aggressive effects on the edges of the sheet, we do not recommend using this tool.

Is it possible to use an electric jigsaw for cutting a profiled sheet?

Yes, this is one of the most popular options, especially an electrician with a laser pointer. this tool can quickly cut a sheet without getting down from markings.

In what cases do they use?

When you need to get a curly or straight section on one or more sheets of corrugated board up to 21 mm high. To cut a pack of sheets, this tool is not used. the jigsaw may fail.

An electric jigsaw is often used for cutting a profiled sheet because:

• Almost everyone has it, it does not need to be additionally purchased.
• It is easy for them to work, this does not require special skills.
• With the help of an electrician, you can cut corrugated board at any angle.

This tool is suitable only for a profiled sheet up to 21 mm high (not higher than the S-21). If you have chosen material with higher corrugations, it is better not to use an electrician: it will tear the metal. Also, he does not have enough blade length for cutting corrugated board with high waves. On the functionality of the tool, working with such a material will also not affect the best way. it may break.

When working with an electrician, there is a possibility of overheating of the metal. To avoid this, follow our tips:

• Control the power of the jigsaw. It is not necessary to turn on the tool at full power, otherwise you run the risk of overheating of the metal and burn the polymer and zinc coating.
• Periodically drip on the blade oil (any). This will help reduce friction, which means that the metal will heat less.

Attention: In the process of cutting a profiled sheet, a small metal shavings forms. It must be quickly removed with soft fabric (do not use an abrasive brush for this! You can damage the polymer coating). Otherwise, the remaining metal pieces on the surface can begin to rust and spread corrosion around.

Is it permissible to use the “cricket” nozzle on the drill?

This is also a rather popular tool. Almost everyone has a drill, for her you just need to buy an inexpensive nozzle with which the drill will work like electric wizards. Also do not forget to purchase a set of replaceable blades.

Drill with a “cricket” nozzle carefully cuts metal without deformation of the edges of a profiled sheet. The edges do not bend, they do not need to be straightened subsequently; The edges are even, without “burrs”.

In what cases do they use?

For longitudinal or transverse cutting of profiled sheets, for figurative cutting, for cutting inaccessible areas. The thickness of the metal should not exceed 0.8 mm.

Attention: During cutting, the drill nozzle should be located strictly perpendicular to the surface of the profiled sheet. In this position, the tool will work correctly.

Whether the cutting scissors are used to cut the profiled sheet?

Yes, they use it. They have three main advantages:

• Cut the metal faster than an electrician, and in speed they are comparable to an angular grinder.
• With their help, you can start cutting the sheet not from the edge, but from the middle (the tool cuts out the hole in the right place in the sheet).
• Do not deform the edges of the profiled sheet. Fishing line for the trimmer of the cut is flat.
• They cut the profile with any height of the waves and any thickness of steel.

The issue of temperature

You can reduce the number of sparks in any means and way that will help to significantly lower the temperature in the epicenter of the working area, in the place where the most dense contact of the sawed material and the disk of the corner grinder occurs. Even ordinary water can lower the number of sparks flying in all directions.

We use oil

Conventional motor oil will help reduce the number of sparks flying in all directions, although it will not completely remove them. Oil applies to the working circle. However, in this matter it is important not to overdo it with grease. In fact, it is better to choose more modern and advanced means to reduce the number of hot particles.

The road to ceramics

Reduce the number of created claims, as well as increase the duration of operation of the consumable elements of the corner grinder can be due to the acquisition and use of a special ceramic disk. Disks from modern materials are much better than “classic”. Of course, for the use of such a “fashionable” device will have to be appropriately paid from your

Cooling powder

Today on sale you can find cooling powders for working with a corner grinder. This tool helps to lower the temperature of the disk and material during operation, as well as “tie” small particles of the metal, significantly reducing the number of sparks created. Before using the powder, you should get acquainted with the instructions for it without fail.

Shield

Protective shield. a mandatory accessory when working with a corner grinder. It works without it. dangerous for life and health, exactly, like without the use of other protective equipment (glasses, gloves). In principle, the shield will definitely not save from sparks, but it will help protect the employee from their dispersal in all directions. Cheap and angry.

In the continuation of the topic, read about sparks from corner grinders: is it worth it to be afraid during work.

How to cut a corner grinding of a corner for yourself: on yourself or from yourself

Corner grinder is a universal tool, without which not a single construction is complete. However, there is no single rule how to cut it correctly or from yourself. Opinions were divided. Each method has pros and cons of. One thing is known for sure, the main thing in working with the tool is safety.

corner grinder or corner grinder what is it

Corner grinder around the world known as corner grinding mash was created by German designers in 1954. Electromechanical tool for grinding, cutting and cleaning the material. In the former Soviet Union, the instrument came from Bulgaria, where it was done at that time. Therefore, the corner grinder received such a nickname.

• Large: length 400. 500 mm, height 140. 160 mm; Power up to 3 kW. Used in production.
• Average: length 300. 350 mm, height 130 mm; Power up to 1.5 kW. Apply for professional work.
• Small: length: 250. 270 mm, height 90. 110 mm; Mine power 1.2 kW. For household works.

With the help of corner grinder, a stone, metal, plastic are treated. Wood is not recommended to cut corner grinders for security purposes. For each material, certain circles are used.

How to cut it correctly

All workers who use the corner grinder divided into two camps. Some cut from themselves, others on themselves. There is no single rule, only recommendations. Proves this that the tool can be configured both under the right hand and under the left, and the rotation of the disk is rehearsed in both directions.

Cut from yourself

When the corner grinder is tuned in such a way that the disk is spinning clockwise, you need to cut the material in the direction from yourself. If you cut on the contrary, the grinder will jam the machine, this will damage the disk.

The main drawback of this method of work is that sparks and dust flies to the carrier. If a brick or concrete is cut, a respirator is dressed, otherwise the respiratory tract clogs with dust. Clothes are thoroughly fastened to reduce dust enters for overalls.

When cutting metal towards the worker, a sheaf of sparks flies. This can lead to a fire of workwear. Cuffs on the sleeves and the shafts of the trousers are tightly tightened so that the sparks do not get on the skin.

The main argument used by supporters of the cut from themselves is safety. If the disk is bitten, the corner grinder is pulled out in the opposite direction from the cutter, and the probability of injury is reduced.

Important. To change the direction of rotation of the disk, a protective casing is turned over by 180 grams. Twist the handle into the hole on the back of the gearbox. Everything is thoroughly twisted and checked.

Cut on yourself

When on a corner grinder, a cut.off disk rotates counterclockwise, the correct direction of the cut on itself. Otherwise, the corner grinder will jam and the disk will be scattered.

The disadvantage of this method is the risk of injury. If the drive bites the driving force throws the tool towards the cutter. If the corner grinder does not hold tightly, it can lead to serious injuries: deep cuts or severe bruises.

Therefore, with this method of work, a complete concentration is required, the hand is rested on the stomach and control the drive course. If the machine begins to work with voltage, this is a sign that you need to be careful.

The advantage of the way to cut on yourself is that sparks and dust flies in the opposite direction from the cutter. This does not mean that there is no need to observe precautions, but in the case of dust there are fewer problems.

The gearbox of the corner grinder, when it is tuned for carvings on the side of the cutter, is less likely that it wraps overalls to the disk. But this rule acts for those who have the right work of the right. For left.handed corner grinding is set individually.

Important. After the disk bites hard to unscrew the fixing nut. To do this, cut out of thick paper or thin rubber the washer the size of a nut and inserted between the disk and the clamp. Even if the disk jams the nut is unscrewed without abrasion or heating.

Necessary security measures

The main thing when working with a corner grinder is safety precautions. It doesn’t matter which way the sparks fly, if not observing security measures, this will lead to serious injuries.

Precaution measures in working with an angular grinder:

Safe place of work

Before starting cutting, prepare a place for work. Clean the site of garbage so that nothing interferes with working. Easily ignited materials and combustible substances remove from the site. Check the place for power cables.

The place is chosen with good natural light. If this is not possible to install lanterns or daylight lamps.

They work with corner grinder only in dry weather, you can not cut rain on time and in the rooms flooded with water.

During work, jewelry, chains, key fobs, objects that can fall into the mechanism are removed during work. So that they do not wrap them on a disk.

The construction site needs a class A, B or C, it all depends on the place of work.

Individual protection means

Be sure to use protection products for the eyes, body, arms, legs and hearing. The equipment must hold tightly, so as not to fall into the rotating part of the corner grinder.

During cutting, a sheaf of sparks that can get into the eyes flies. To protect, put glasses or mask made of transparent plastic.

The sound of a working corner grinder irritates the auditory membranes to protect the ear is inserted or put on construction headphones.

They work with corner grinders in working gloves to avoid cuts and abrasions. Chosen mittens in size so that they do not hang on their hands and do not accidentally shine on a rotating disk. Also make sure that the mittens are not torn.

The road to ceramics

The best ceramic disk. /

Reduce the number of created claims, as well as increase the duration of operation of the consumable elements of the corner grinder can be due to the acquisition and use of a special ceramic disk. Disks from modern materials are much better than “classic”. Of course, for the use of such a “fashionable” device will have to be appropriately paid from your

Thermal tool

This type of mechanisms cuts the metal by exposure to certain substances heated to high temperature. Since it is used in large production in working with large volumes, therefore it involves the purchase of expensive overall equipment.

It is divided into the following subspecies:

• Gas or oxygen effects:

• oxygen;
• oxygen-color;
• oxygen-cake.

• Gasoelectric effects.

The use of such a tool allows you to cut thick metal, but one of the disadvantages, at the same time, is a large number of production waste. Using such a tool, it is difficult to achieve high accuracy, and the metal is subject to deformation under the influence of high temperatures.
