Cast iron cut with a hacksaw on metal. Cutting speed

How to cut a cast.iron pipe with your own hands

As with any metal, the methods of cutting cast iron are divided into thermal and mechanical. The choice of a specific tool depends on the design features. The equipment is given below, which cuts (or cuts) cast iron:

• pipeline;
• angle grinding machine;
• chisel;
• Kryzuvka for metal;
• lobby
• plasma installation;
• Gas cutters.

Now it is worth evaluating cutting using these tools with cast iron objects.

Work with a hacksaw for metal

Solving how to saw a cast.iron bath, do not forget about a knife.haired. The principle of operation is the same as the sawing of a corner grinder. The advantage of the option is only one. a hacksaw is safe.

• This is an extremely expendable way. to cut a large diameter pipe for several hours;
• Will have to make a lot of physical efforts;
• You can only work if there is enough space around the cast iron.

An electric power can be a simpler option. It’s easier and faster to work than a hand hacksaw, while the tool is cheaper and more affordable than corner grinder. Due to smaller sizes, electricity is easier to work in limited conditions.

Gas cutting

Gas acid cutting is effective, but limited to metal thickness. If you need to improve the quality of the cut, then you should look towards cutting cast iron with an oxygen-fluis.

An example of cutting cast iron by a supersonic cutter Terminator 220:

Quite suitable even for work under water.

The mobile installations of thermal cutter have proven themselves well. For example, the simplest 2M model (less than 5 kg) cuts cast iron (without the introduction of a burner into a cut cavity) by 150 mm. Information from the developer:

Oxygen-digging cutting. Oxygen spear is a steel tube through which oxygen is passed. The working end of the oxygen spear is heated to 1350 ° C (for example, a welding burner), then the oxygen is compressed, which is ignited at the end of the spear reaches a temperature of 2000 ° C. To increase the power of the spear inside the tube, placed a steel rod.

Castling plasma is the most productive option, but it is the most expensive.

Recommendations for cutting metal pipes

Cutting pipes from different metals is a demanded operation during repair and construction work. It is necessary to cut off the products when installing sewer and heating systems, water lines. In this direction, the corner grinder copes well with various tasks. Disks for work are chosen according to the material from which the pipe is made.

The use of a corner grinding machine makes it possible:

• cut pipes at different angles, for example 45 and 90 degrees;
• cut large diameter products;
• Exactly cut profile (rectangular or square cross section) pipe;
• make longitudinal cutting of tubular blanks;
• saw cast iron pipes;
• Cut the thin.walled tubes.

If you need to cut a large diameter pipe, then the use of a corner grinder allows you to perform this work without significant cash costs. But at the same time, labor productivity is small, and the risks are considerable. When long pipes lie on the supports, only hanging parts are sawn down. If you saw it in the center, then the cuts of the cut will clamp the rubberized circle, which will lead to the jamming of the tool and the possible injury.

Experts not only cut pipes from different materials at the desired corners, but also cut the holes of the required forms in them. Work with specialized and round blanks is carried out in a similar way, with mandatory compliance with safety regulations.

Cutting pipes at different angles

Cut at an angle of 45 and 90 degrees round and profile pipes is necessary when laying various communications. In any case, it is necessary to sprinkle the pipe evenly so that the elements that need to be connected are maximally connected to each other.

A cut at an angle of 45 degrees of cylindrical pipes is carried out as follows:

• take a regular square paper sheet;
• fold it exactly diagonally;
• The pipe is wrapped with this template;
• with a chalk or other marking device, the future fishing line for the trimmer of the cut is applied;
• remove the template;
• clamping the workpiece in a vice;
• cut off the marked fragment of the pipe.

When applying the template, any of the two short sides of this triangle should be parallel to the central axis of the pipe.

When it is necessary to cut at an angle of 90 degrees, the pipes are simply wrapped in a circle (cylindrical) or along the perimeter (profile) sheet of paper. After that, a fishing line for a trimmer cut is marked. You can also mark the profile pipe very simply with a regular square.

If it is necessary to cut at an angle of 45 and 90 degrees a significant number of profile pipes, the corresponding templates are made from this material, only of a larger section. This allows you to perform the required measurements only once. In this case, for the initial marking, a construction square is used, or transportation. When the template is made, cut blanks are inserted inside it, noting the cut line. Then the sawing is performed.

Features of cutting cast.iron and thin.walled pipes

Cast iron is a fragile material. To cut the cast.iron pipe with a corner grinder, act in the following sequence:

• mark the fishing line for the trimmer of the cut;
• put a wooden block under the pipe, which will serve her support;
• make cut along a contour a depth of several millimeters;
• insert a chisel in the depression made;
• on mentoring strongly and abruptly hit with a hammer.

After the blow, the pipe will split along the cut line. Its edges will be quite even. If necessary, they are additionally processed.

To perform the longitudinal sawing of the pipe, the exact marking is also important. For its application, various devices are used, for example, a construction thread (“beaten”). The whole process of sawing should be carried out carefully, slowly, so as not to go astray from the marked line.

Thin.walled pipes are one of the varieties of this kind of products. They are often made of non.ferrous metals: copper or aluminum. Their cutting is a difficult occupation. In this case, the corresponding workpieces of the corner for corner grinding.

The sawing of thin.walled tubes must be performed very carefully, because they can easily be deformed even from applying an insignificant load

Mini-cut

Mini-cutting is a type of portable autogen to work on metal, but with an even smaller size.

In fact, a mini-cutting is a lighter with a gas cutter, which is located on top of the device.

At the same time, the characteristics of the apparatus are pretty good: the mini-autogen has a good pressure of the flame and the sufficient size of the gas tank, which allows you to do work with it even with windy weather.

But there is one nuance: prolonged combustion can greatly heat the upper part of the mini rezak, and the parts made of plastic can melt, and it is not possible to carry out repairs or replacement in most cases.

The mini-hot paper has the same principle of operation as the unit of standard sizes.

But due to the fact that, the volume of the cylinder with the gas is small, it must be periodically refueled (you can use the usual Tsang cylinder).

Of the minuses of the mini-glass, you can also note a small length of the outgoing flame, so working with some types of metal on them is extremely uncomfortable.

Basically, such mini-options are used by jewelers or craftsmen who repair air conditioners and refrigerators, as they are very convenient for working with their own hands with small items.

In everyday life, a mini-hot butter is used to ignit the fireplace in a private house or in the country.

Pipeline

This is a special device for cutting pipes from different materials. Distinguish manual (mechanical) and electrical tools. Both species are suitable for diameters of 15-360 mm.

First, a carbide disk is planted on the device. The removable element has a number of advantages over classic abrasive. For example, 4 times increased cutting speed, lack of sparking and the need to add any substances to the cutting zone. Diamond spraying is applied on top of the cutting edge, prolonging the service life of the products. Examples of pipelines for cast.iron pipes. Exact Pipecut portable products for diameters less than 360 mm.

Alas, rarely a home pipeline will easily succumb to cutting with a pipeline. The tool can be complicated to it or the cutting place is bent so that the device cannot be captured. Therefore, it is worth considering other options.

Disks for equipment

Products from various materials (cast iron, highly alloy stainless steel, non.ferrous metals) require the use of discs of the corresponding type. When using cutting circles on an angular grinder of the required type, work will be performed very quickly and safely. Each material is processed specially for it made.

On the lateral part of the abrasive tool there is information in the form of a marking characterizing its purpose. You can not use ordinary circles for the sawing stainless steel. They consist of substances that destroy the protective film of this material, which is fraught with the beginning of corrosion processes.

For cast iron, a variety of solid steels, soft and non.ferrous metals, appropriate types of disks are produced. They differ in the composition of fillers that contribute to the most effective work. Some products contain a soft ligament that does not form plumbing, which is relevant with the cut of non.ferrous metals, as well as aluminum products. Super.strength additives help to overcome the resistance of the alloyed steel.

The produced discs have three sizes in diameter: small (115, 125 mm), medium (150, 180 mm), as well as large (230 mm) used in professional models with a capacity of 1,500 watts. The planting size of the above products is the same. 22.2 mm.

Sawing stone, concrete, brick, slate is performed by special discs that have diamond spraying. These products are available for wet, dry cutting, as well as combined. Color marking on the side of the diamond circle facilitates the choice of the required copy.

Special wood work discs belong to the most dangerous tools. They have small teeth and are not intended for installation on corner grinders of large sizes. When working, it is necessary to use protective covers or inpatient fixing angular grinder.

Work with a chisel and a hammer

This pair of products will help divide cast iron in an inaccessible place. Dismantling work begins with pipes removed from the riser in places where you do not stick a corner grinder or hacksaw. Since cast iron is a fragile material, it is easily destroyed after point dynamic loads.

A good shock tool has a rubber or polymer nozzle to slightly soften the blow. This is necessary so that the pieces of cast iron do not scatter around, do not get into the riser and do not create a blockage.

The chisel and the hammer work perfectly with the cast iron of the Soviet era, that is, connected by sulfur, aluminum and cement. As you move to the riser of free space for work, as a rule, it becomes larger, so further cast iron can be cut off with a more effective device. As with a corner grinder, when working with a chisel, it is recommended to close the areas of the body into which a cast.iron fragment can fly off.

The performance of the work is extremely small, but sometimes without them in no way.

Types of hacksaw

There are the following types of scabbard for metal:

Home. The simplest options that are in the set of each master. Such devices are considered an obsolete option, but their production continues to this day. The advantage of these tools is the simplicity of the design. The handle is made of wood, and is located in the same plane with the canvas

Locksmith electro.burning

If you rarely have to cut long sheets, then buying special tools for cutting metal does not justify itself.

It is enough to have a regular electric hacksaw. The machine with electronic control of the frequency of moves is more convenient, which allows you to coordinate the cutting speed with the material and with a hacksaw canvas. Most of the 300-400 watts of electrical hacksaws are used to cut blanks of structural steel with a thickness of 5 mm and aluminum-up to 15 mm. When performing long cuts, lead a machine along the support bar.

Beware of the chips

Electric hacksaws are moved by a traction force, that is, a push (actually cutting movement) occurs when the canvas moves up. Metal shavings flies, therefore, also up. Therefore, protect your eyes with safety glasses, and hands. mittens! Do not be frivolous!

Long straight cuts are good to perform a locksmith with an electric drive. The machine needs to be carried out slowly and without pressure.

Tuning into a cast.iron pipe

During the operation of a cottage or a country house, sometimes it becomes necessary to make a selection from the water supply or additional drain into the sewer for the washing machine.

This issue is resolved using the “Test” method. How to insert into a cast.iron pipe?

In most cases, it is possible to use the finished tee, the diameter of which is slightly larger. You should cut off that part of the pipe from it where there is no pipe.

You usually have to cut the pipe along, drill a hole and weld to the rest of the pipe.

The flange to the pipe is attached around the entire perimeter using welding. This is quite difficult to do without special skills. In this case, you can use the use of sealants and clamps, which will make the insert into almost any pipe in the house.

Often arise in the everyday life of a situation when you have to work in extreme conditions. One of the most difficult works is to drill cast iron, t.to. It belongs to abrasive materials. There can be many reasons: from the finalization of the bath to personal technical ideas.

Plasma cutting

The method is more likely to be industrial than household ones, so it will not be considered in detail. If the goal is the minimum consumption of material, speed of work, noiselessness, there is no better equipment for cutting cast iron. Plasma will make cuts in the workpieces with a thickness of more than 200 mm, and the sawing material at the end of the work almost does not have to be processed.

The method is used by large enterprises of metallurgy, industry, where there is a need to cut and transport cast iron scrap. Plasma installations are indispensable for volumetric work.

Detailed instructions for drilling cast iron

The tools and materials necessary for work:

Before drill the hole in the cast iron, you need to clearly define the goals and objectives, t.to. you need to see exactly the final result. During drilling holes in the bath, errors are made without preliminary experience. The three most common are sliding holes, enamel chips and even drill breaks.

Before you start doing anything, you need to make sure that you really have cast iron in front of you. The easiest way is to try to raise the product. If it does not rise due to a huge mass, then there was no error. Otherwise it is ordinary steel.

The most important aspect that cannot be forgotten throughout the work is the lack of haste. Even if it is very necessary and squeeze the deadlines, the cast iron should be drilled with cruising speed, t.to. The material is not only very hard, but also very fragile, which is why you can inadvertently say goodbye to a cast-iron product.

Now you can start preparatory work. At the very beginning of the preparation, it is necessary to install all the necessary marks on the surface with the help of a black or red thick marker. Small points are placed so that during work, not by chance, do not take the drill from the selected positions.

The drill should be made of carbide steel, and its sharpening should be impeccable. The drill should be on a metal with an angle of 116-118 degrees, so as not to scratch the surface, namely. If this moment is not taken into account, then with a very high probability the enamel will not cut off a cautious circle, but will split, letting out cracks around him.

If there is a desire to be safe, then you can use a wooden bar. A hole is made in it, 2 mm exceeding the used drill, so that there are no difficulties in the process of professional activity. This block should be 2-2.5 cm in thickness, so that the drill does not walk even if the hand flutters. The bar will be applied to the surface during operation so that the point marked in advance is visible in the center. It will need to be pressed with 1 hand, while the other is organized the entire workflow.

Often, beginners forget or purposefully ignore the cooling of the drill, which is why the workflow is much slower, and the drill itself wears out faster. In order to avoid this, you need to use a kerosene solution. Its consumption is small enough to evaluate the drill more expensive.

There is another way not to harm enamel and at the same time do everything extremely high quality. use a corner grinder. Instead of the usual cutting disk, you need to string with a grinding, which a patch of enamel is safely cleaned, and only then the actions described above are carried out. This approach does not only minimize risks, but also significantly accelerates the process. Usually grabbed an additional 2 mm to the diameter, t.to. In this case, the result will turn out without a flaw.

The most important primary products of ferrous metallurgy, cast iron are widely used in various areas of world industry. They serve as the starting raw materials for steel production, are used in mechanical engineering. Being known for more than three millennia, this metal today reflects the level of industrial development of its countries producing it.

Throughout history, the production of cast iron has developed and improved. And today, the use of this metal in some types of industry cannot be replaced, so cutting and drilling cast iron is so important. Due to the high carbon m, different methods and a special tool are used for cutting.

As a rule, in domestic conditions, the use of drills with winning nozzles (for example, VK8 can be recommended

). Such a cast iron drill should be used at small speeds, observing the verticality of the effort and performing frequent cooling of the cutting nozzle, preventing it from overheating and blackening.

Cast iron cutting corner grinding. metals, equipment, instructions

Most often, the need to cut a cast.iron structure occurs when dismantling outdated communications. The hope for a quick completion of work collapses immediately. in the Soviet Union, the pipes were connected with cement, gray and aluminum, so it is incredibly difficult to cut them. But a couple of working techniques are known. You will learn about how to cut cast iron and designs from it from the material below.

Methods of cutting material

As with any metal, the methods of cutting cast iron are divided into thermal and mechanical. The choice of a specific tool depends on the design features. The equipment is given below, which cuts (or cuts) cast iron:

• pipeline;
• angle grinding machine;
• chisel;
• Kryzuvka for metal;

• Gas cutters.

Now it is worth evaluating cutting using these tools with cast iron objects.

Exact Pipecut portable products for diameters less than 360 mm.

Alas, rarely a home pipeline will easily succumb to cutting with a pipeline. The tool can be complicated to it or the cutting place is bent so that the device cannot be captured. Therefore, it is worth considering other options.

Angle.grinding machine

It works quickly and comfortably, but not without minuses with a corner grinder. For example, she cuts only in a straight line. An attempt to make a curly cut will lead to a “snack” of a disk, its breakdown, a possible user injury. Therefore, the machine is used for cutting in a straight line. Another minus. the fire hazard of the method (abrasive disk metal = sparking). Before work, you will have to put on glasses, protection on your face and hands.

Cutting more efficiently than a jigsaw around, so more often users choose a noisy corner grinder. When buying a cut.out circle, prefer products on a bakelite bunch, because they are an order of magnitude stronger than ceramic analogues.

Kryazuvka for metal

Similar to the corner grinder principle of operation. You will have to mess with her for more than one hour, especially if you cut a large diameter pipe. Cons of the method. temporary costs, physical efforts, the inability to work on a limited area. But the method is safe.

Work with a chisel and a hammer

This pair of products will help divide cast iron in an inaccessible place. Dismantling work begins with pipes removed from the riser in places where you do not stick a corner grinder or hacksaw. Since cast iron is a fragile material, it is easily destroyed after point dynamic loads.

As with a corner grinder, when working with a chisel, it is recommended to close the areas of the body into which a cast.iron fragment can fly off.

The performance of the work is extremely small, but sometimes without them in no way.

Electric hacksaw

It is much more convenient for the user to work with an electronics than a corner grinder, although the principle of action is not very different. Lighter device with a smaller linen than the corner grinder, the canvas is consumed more slowly than the disk, if it is correctly selected (the hSS or BIM marking, and the length is also taken into account).

Smaller injury hazard, process speed is something between a corner grinder and a hand hacksaw, the cheapness of consumables and their availability are the advantages of cutting cast iron by electronics.

Plasma cutting

The method is more likely to be industrial than household ones, so it will not be considered in detail. If the goal is the minimum consumption of material, speed of work, noiselessness, there is no better equipment for cutting cast iron. Plasma will make cuts in the workpieces with a thickness of more than 200 mm, and the sawing material at the end of the work almost does not have to be processed.

The method is used by large enterprises of metallurgy, industry, where there is a need to cut and transport cast iron scrap. Plasma installations are indispensable for volumetric work.

Gas cutting

Two methods of gas cutting cast iron are distinguished:

In the first case, the finest stream of flame supplied under high pressure affects the workpiece. The combustion product is usually a mixture of oxygen with kerosene or diesel. By the way, an effective method in the elimination of technological accidents.

The second method resembles a gas acid, only a cutting element is a thin pipe made of hot steel. Its tip heats up to almost 1,500 degrees (welding/soldering iron/lamp), then oxygen is supplied through it, ignited at the output and heated to 2000 degrees. The received burning mixture easily copes with the thick cast iron.

Both methods are good, but there are minuses. it is important to have experience working with gas equipment. Responsible and accurate cutting is performed only by a professional. The second drawback is the release of gas harmful to the health during the operation of the cutter.

The method is suitable for working in the fresh air or in the garage. For example, the need to eliminate a cast.iron lock from swing gates. The cutter works quietly, you will not hide anyone.

Details of use

What disk to use for wood

To cut a tree with a corner grinder, we have already noted that a special equipment for corner grinding machines is presented on the construction market of equipment, which can process wooden blanks. As a rule, we are talking about adaptive discs with expanders in the area of ​​the cut, as well as with an unusual form of teeth. This structural feature is focused on lowering the likelihood of a wedge. At the same time, grinding and cutting circles can be found for wood.

Another option for an acceptable nozzle for such purposes will be the use of chain equipment. But when using it, it will be necessary to take into account a wide capture of cut, approximately 0.8-1 cm. A chain disk with a corner grinder can be sawn the wood to a maximum to a depth of 12.5 to 23 cm. These are standard formats for an angular grinding machine, but the process of work will be very different due to the low level of vibration waves and the lack of risk that the tool will fly out of hand.

Is it possible to cut a tree with a corner grinder with a metal nozzle?

Most of these discs (for metal) have small cloves, and without fail, everything is complemented by diamond or even a win.vein crumb. This makes it possible to work with natural stone and metal. For wood, such nozzles are dangerous, but there are disks models in which the device is almost ideal for soft material to the cutters.

Now, in order to saw the corner grinding of wood with a metal disk, be sure to ensure that two conditions are fulfilled:

• The circle has an average and rare tooth (if it is large, but the risk of wedge will be increased).
• Segments or other inserts on the surface of the nozzle are made of carbide or tungsten.

This design makes it possible to minimize unwanted effects during the work, but according to the rules of safety, even this is not enough to use an angular grinding machine in such operations.

Preparation of corner grinders and blanks for sawing

Consider the fact that the angular grinding machine should be well examined and checked for the performance of functions. It is necessary to evaluate the reliability of the connection, electrical connections, the operation of the protective system and structural mechanisms. Separately, it is worth checking the degree of stiffness of the capture of the nozzle, and if you plan to cut the wood with a corner grinder in the room, then it will not be superfluous to prepare a building vacuum cleaner (or chiphoots) in advance.

Modern models of the Bulgarians have a special pipe to remove dust. connecting a vacuum cleaner to it will make it possible to avoid pollution of the workplace with chips from wood. The workpiece itself should be well dried, cleaned of foreign inclusions, dirt.

The working process

You should start a cut with soft starting if you have such a function on the corner grinding machine. It is important that work at low speeds is ensured, and if necessary, a little later it will be possible to start increasing the moment along the way. Much in the tactics changes in the cut parameters depends on what the degree of hardness of the workpiece is, as well as what sizes it has.

How to cut a tree with a corner grinder if you need to make a slanting cut? Unfortunately, the cut of the cut is not allowed at all, and the workpiece should be cut exclusively at right angles, and any inclinations will be excluded, since the bias as such can be dangerous. Complex operations are non.standard, including even curly cutting, as part of secondary processing by another tools, not an angular grinding machine. After the work is completed, you should wait for the disk to stop, turn off the device and remove the fork out of the outlet. Further, the tool can be disassembled and cleaned of wood chips, as well as dust.
