Cutting profile pipe at an angle. Metal cutting rules with grinder. Pipe paper

Pipes are the most common type of metallic and plastic rolled steel. They are used to transport a wide variety of gases and liquids. On plants, the rental is produced in a certain length. To mount them at the place in the pipeline, the system of heating, water supply or sewage, they must be cut to the desired length. Pipe cut into exactly and with a bevel. For this, many methods of cutting and a variety of equipment are used.

Used tools

At first glance, I am at first glance - cutting pipes in practice detects quite a few nuances and pitfalls. Not so - then just cut off the tubes:

Thin-walled.
Large diameter.
With a bevel.

It is very important to choose a cutting method suitable for each specific case and special equipment. It is divided into individual, domestic and industrial.

For individual use

Apply in households, private construction and shallow business. Deal with small and medium diameters (up to 250 mm) used in systems

Water supply.
Heating.
Sewer.
Ventilation.

This tool includes:

Cutters. Apply to cut off the polymer pipe to 75 mm. To carry out a smooth and neat cut have a gear mechanism. The workpiece is first clamped by a shelter clamp that securely fixes it and does not allow to leave the cut line.
Disk cutter. Suitable for ventilation and sewer polymer pipes diameter up to 200 mm. The blade is not a secateur type, but in the form of a disk, caring on the surface of the workpiece. The incision is carried out for several revolutions. Not suitable for metal-plastic rolled products, because it can minimize a thin metal liner.
Guillotine. A flat braid knife moves in guides and allows you to smoothly cut off the required length in one pass. Available with both electric drive, providing greater performance and manually.
Metal hacksaw. A classic plumbing tool allows smoothly cut off the blank. When using it is important to conduct a saw smoothly, with constant effort and without distortion. Formed after work, the burishes should be cleaned with a file.
Corner grinder, ush. In everyday life is called "Bulgarian". This universal tool on the teeth is any materials and diameters. In order to trim the pipe with a grinder, use special abrasive cutting discs.
Electric jigsaw. A tool is very popular among home masters can cut and pipes, but because of the flexible blade in the direction of the accuracy will only have to dream
Sabelnaya saw. The tool has not yet been widespread among Russian masters. Adjustable pilot stop and its powerful blade allow you to cut off the rental even on the weight and close to the wall.

Technology cutting

As a rule, the volume and complexity of work, the upcoming homemade master, does not require the use of high-performance and expensive production level equipment. In the manufacture of the carcass, the greenhouses can be completely cropped with a grinder or traditional hand-made hacksaw.

Each type of cut has its own nuances, and some require special tricks.

At right angles

The accuracy of the cut is largely determined by the qualitative markup. Experienced masters They advise you to place the lines of the cut is not a pencil, but by painting scotch, observing the following sequence of actions:

To postpone the necessary size and put a small label with a marker or pencil.
Carefully, applying to the mark, plane the detail by painting tape in a circle. The edges of the paper must come together without a shift. This is a sign that the paper is pasted correctly. If the edges did not come together, the tape needs to be seal.
Reliably fix the workpiece to eliminate its movements and preex during work. For fixing use vice, clamps.
Sliced \u200b\u200b(smaller) piece of workpiece should be left on weight so that it does not clamp the blade or disk.
The incision starts from the top.
Disk of the grinder (or canvas of the hacksaw) lead exactly along the edge of the painting tape, without deviating to the side.

This is allowed to smoothly cut off the required length.

If the diameter is large, then the markup is performed in the same way, but they cut into parts, sectors of 30-60 °. After cutting the next fastening sector weakened and turn the pipe. Next, they are fixed again and continue to cut off from the place where the previous sector ended. In order to succeed exactly, special attention should be paid to the beginning of the cut, avoiding steps and care.

Oblique incision at 45 °

Cut the end of the pipe exactly under 45 ° possible without the use of complex devices. It is enough to apply a plumbing smell. It will take to do the following:

Cut paper sheet in the shape of a square.
Folded diagonally. The rectangular isceived triangle will learn.
Wrap the workpiece of the leaflet so that the triangle can be perpendicular to the axis, and the hypotenuse formed an upward spiral.
Secure a sheet of scotch.
Fix the workpiece and cut the leaf on the oblique edge. It turns out at 45 °.

There is another one people's method. The end of the workpiece is immersed in a container with a liquid under the required angle. Cut is needed along the border of moistened and dry plots.

If it is required to cut off not perpendicularly, it is better to use an ancient carpentry tool - stub.

This is a P-shaped pattern, in the side walls of which slots are already made at given angles. The pipe rests on the far from the master of the wall of the stub and pressed there with a hand or hand clamp. The canvas of the hand saw will be set in the appropriate grooves and saw. If necessary, cut off with a different angle, you can make additional feeding in the walls of the stub.

Takes cutting pipes at an angle

Receptions are not perpendicular cutting depend on the material being processed. Some techniques are suitable for plastic or fine copper - plastic and lung materials in processing. Thick steel will require a more serious approach.

Plastic pipes of small diameters can be trimmed using specialized scissors.

Steel pipes can be cut off with a grinder, but it is better to use a more accurate tool - ribbon Saw. With a turntable equipped with clips. A table disk cutting machine is also suitable.

When using a general-purpose tool, it will be necessary to use a snap-in.

Reserve Corner Calculation Programs

Land for render 45 ° can be obtained by folding the square sheet in half. For the formation of patterns to other squeezes, more or less complex trigonometric calculations will be performed. For those who have safely left sines and cosines in high school and is not going to remember the formulas, a variety of calculation programs on any necessary angle are available on the network. The program performs a calculation for the user-defined diameter and angle of the cut and creates the image of the pattern to be printed on its printer.

IMPORTANT: In print parameters, select the option "in full size" and disable the image scaling.

In order to cut off at 45 ° smoothly, you can independently make paper melts. This follows:

Measure or calculate the length of the outdoor circle.
From the corner of the sheet of paper for the A4 printer, hold the line at an angle of 45 °. If there is no shipping, such a line can be obtained by folding together adjacent to the edge of the sheet.
It will postpone the length of the circumference.
It will be hypotenuse. Further an equally chaired rectangular triangle. One side will be the edge of the paper, the second should be omitted perpendicular to the second edge of the pending point.
Cut the resulting triangle is and it will be leather for cutting pipes at an angle of 45 °.

It should be wrapped around the workpiece, aligning the ends of the hypotenuse. On the line of cathets and will take place. The line should be marked with a marker or paper scotch. Next, on the lined line, it will be possible to cut off a piece with the required bevel.

The method is suitable for pipes with a diameter of up to 63 millimeters.

Carpenters have long used to use simple, but very useful fitTo smoothly cut off the angle of the ends of bars, rectangular, round and shaped. A carpentry stub is not bad for sprinkling a plastic or not a thick metal pipe.

You can use ready, and you can make a stubble with your own hands. Its advantage will be that it can be done exactly under the size of the pipe. For manufacture, you will need:

Cut the board with a length of 40-50 cm and a width equal to the pipe diameter.
Cut two boards of the same length, but wider on the thickness of the first board.
Collect boards on self-drawing, attaching the side to the base so that it turns out a P-shaped chute.
In the center to place and make vertical rods in the side boards to the base so that directly made through them formed with the longitudinal axis of the corners of 90, 60, 45 and 30 °.
If necessary, make feeds under other angles.

The side walls are better made from the tree of more durable rocks - it will extend the life of the equipment.

Easy cutting

Universal cutting machine with pendulum disk saw Great to smoothly cut down the thick-walled pipes of large diameter, both round and rectangular in cross section. Such devices operate on the procurement sites of small industries and on construction sites, where it is necessary to smoothly cut a large number of fittings in size.

The disk saw together with the electric motor is fixed on the pendulum lever and can with great accuracy working area And further led in one plane.

Advanced devices are equipped with a hinge lever, allowing you to change the direction of the cut. In the models of the lower and medium price segment, the orientation of the cut line is carried out due to the rotary table equipped with clamps for reliable fixation of the workpiece. In addition, the table can be tilted up to 45 °. Rotary table I. lifting mechanism Equipped with vehicles that allow you to set an angle with an accuracy of degrees.

For reliable fixation of the pipe at a given angle, clamps and two steel corners with a side, close to the diameter of the pipe, are applied. A short corner is fixed on a rotary desktop, using its regular screw clips. The process of fastening and cutting down the steps:

Set rotary table To the desired corner of the cut and consolidate it.
Lay the pipe between the corners and pull them out the hand-made clamp so that the placed line of the cut remains free.
Start the engine.
After a set of revolutions, smoothly reduce the disk to the metal surface and smoothly cut off the workpiece. At the beginning and end of the cut, when the cross section of the metal is maximum, should not be made of great effort to the pendulum handle.

The main advantages of this method:

high performance, including with thick walls
smooth and smooth cut, requiring minimal stripping and refinement with a file
no need to build patterns.

Features and disadvantages:

applicability to small and medium diameters
high cost of machine
small mobility
high power consumption and noise

Nuances of work with a rectangular cross section

To cut off the rectangular profile Exactly, experts recommend pre-preparation patterns. The easiest way is to make templates from a steel corner of sufficient size marked for the desired beep. This greatly saves the markup time with a large amount of the same type of incisions.

The corner is applied to the profile pipe on the side and on the beats, place the line of the cut by a marker or hell. It is recommended to repeat it with paper scotch.

Cutting machines

Ribbon saws are characterized by a high stability of the plane of the movement of the canvas and the precision of the cut. They are also widely used on the procurement sites of small-sector and medium-sized industries. They are characterized by versatility, reliability and high performance.

For private use, MASS from Italy offers a compact tape sawing unit. It is equipped with a hand clamping device and can smoothly cut pipes with a diameter of up to 65 mm, as well as rolling of any profile of the same thickness.

Rotary device allows you to set an arbitrary cutting direction from 0 to 45 °. The frequency of the cutting blade is up to 45 clocks per minute. The economical engine of 370 watts allows us to use the usual home-to-one-phase electrical circuit with a voltage of 220 V.

Application of thermal methods

In addition to mechanical, thermal methods of cutting pipes are also quite widely used. Here the tool is a gas cutter (propane or acetylene) or an apparatus of electric arc welding. The gas cutter is subject to even the most thick-walled pipes of large diameter. Quite high and performance. In addition, only these methods provide exceptional mobility - it is possible to cut off the pipe into the trench, basement - in such places where the high-performance stationary machine is simply not to drag and do not connect.

It should be noted that thermal methods do not allow to achieve high accuracy, and even cut off, too, does not always work. However, in a number of applications, such as operational repair of heat mains or main pipelines, it is not required. After the cut in the thermal method, the resulting edges have to additionally handle mechanical tools, align the cut line and display the squeezes to design values.

The thermal cutting method also applies when working with polymer pipe rental. In thermal guillotines, the cut is carried out heated to high temperatures oblique thin cutter, sliding in the guides.

Devices can also cut at an angle and very smoothly, but suitable for work only with soft materials having a low melting point.

How exactly cut off the profile pipe

It is recommended to use a plumbing square when markup. On the first side, the desired size is noted, the square is applied to the label and the markup line is carried out. Further, without taking off the coal from the corner between the faces, smoothly turn it onto another, apply the markup line, turn again and place the third facet. If the lines come out on the last facet, it means that the markup is made correctly.

Now you can consolidate the workpiece and cut off the desired length with a grinder or hacksaw.

Cutting pipes of large diameter

If you need to cut off exactly the pipe of the large diameter, for sewage or entry into the site, the following tools are used:

Angle Grinder. Affordable but not very safe method. A certain skill is required. Be sure to use personal protective equipment.
Roller cutter. This is a rather complicated unit specifically designed for such work. It is mounted on the pipeline, covering it outside. The force of pressing rollers is adjustable using mechanics or automation. For each diameter it takes its own snap.
Gas cutter. The most frequently used method. The method is quite safe with sufficient qualifications of gas welder and compliance with the precautionary rules. Requires a gas cutter, cylinders with acetylene or propane.

How to cut the cast-iron pipe

Cast iron as a material has its own specifics and differs from steel alloys by a number of physical and mechanical characteristics. With the high strength of the cast iron - very fragile material.

Placed a cast iron pipe just as steel. Before starting work, it should be put for a support wooden chumbachk. Corner grinding with a cutting disk need to make a shallow incision throughout the circumference. Further on the chisel inserted into the incision, you need to strike a lot of power. The product exactly splits on the line inscribed.

If the ushm is not available, you will have to make a ring with a hacksaw metal.

How to cut along

Not often, but sometimes it is still necessary to cut the pipe along. It should be done as follows:

Gently post the cut line. Use chopping thread, marker or greasy tape.
Secure the pipe, glad with a pipe to provide support for your hand along the entire line of the cut.
Not in a hurry, slowly moving the ESM drive along the cut line and keeping the support of the hand, perform a cut. It should be constantly monitoring the depth of the disk dive into the incision so as not to soak the opposite wall.

How to cut thin-walled pipes

When working with thin-walled rental, there is a high risk of crumpled edges. To avoid this, the profile filling from the inside is used:

when working with a knife, a round wooden wand of a suitable diameter is inserted

In various situations, the wizard of the household level often come to the question of the correct markup for the exact cutting of pipe blanks at an angle of 45 degrees. To date, there is a huge selection of tools, both for the household and industrial process cutting pipes at any angle. The cost of such devices is quite high.

How to cut the pipe at an angle

It is proposed to consider the methods of marking of blanks for cutting at an angle of 45 degrees in domestic conditions without the use of professional expensive equipment.

Marking and cutting pipes

Tool for cutting pipes at an angle

The process of marking the cropped blank seems sufficiently simple business. But it should be noted that the manual-allowed curvature in the process of marking will create an irreparable error after circumcision, which will entail the nonstoves and the formation of defective products. In order to exclude such defects, a simple tool is required for a clear markup of profile parts. At the same time, cutting of products at an angle 450 is much simplified.
The usual segment of the steel profile of the P-shaped form, made at an angle of 45 degrees, will become a reliable tool for accurate cutting pipes. At the same time, the profile size for the ruler must be selected so that the possibility of easy location in it is cut profile pipe.

Manual pipe cutting tool

To perform such notes the correct angle of the tool, you must have another additional tool:

Correiler;
Metal checker;
Bulgarian;
Disk for cutting;
File.

How to cut the pipe at an angle

Perform a measuring tool for cutting pipes is easy. To do this, from the profile blank it is necessary to cut a length of 20-30 cm. By means of a grid, an angle of 45 degrees will mark an angle of 45 degrees. Next, the grinder cut off the profile. The resulting pattern is required to experience accuracy. In case of deviations to process a measuring device with a file.

Using such a notmerizing tool made own hands, much simplifies the process, especially with their large volume. For a mark, it is only necessary to arrange the correct corner in the made fixture, the correct corner is delayed by the drawer. In the process of marking, the length of the products is monitored. Next, you need to cut off the pipe clearly along the markup lines using the grinder. It is worth noting that at first a pipe is caught in diagonal marks on both sides, then straight marked lines cut through. Such templates for trimming pipes at an angle of 45 degrees will sufficiently save time and means.

Marking and cutting circular pipes

In the case of cutting round pipes at an angle of 45 degrees, a tool made for rectangular pipes is not quite suitable. For a more accurate - streamlined drawing of the cut-off line at an angle, it is recommended to use paper mandrels that wakes up on the workpiece.

Pekal is being developed in the modern world using computer programs.

The cut line varies depending on the corner specified in the program and the pipe diameter. The common patterns can be found on the Internet or remember our painted rules with a school bench.

Pipes - widespread construction material. They are applied in the installation different systems. In the process of installation, the situation occurs when the pipes must be shown at an angle. The technology of production of such works is not standard, but it is necessary to know about it.

To create a complex connection configuration, cutting pipe cutting at an angle. We will tell you how such operations are performed and what are the cutting methods.

Considering the workshops - cut directly or at an angle - the various material of products subjected to the processing. So, the sleeves made from polypropylene or fine copper, cutting easier and easier than thick-walled steel pipes.

Plastic products of small diameters are trimmed under the desired angle with. At the same time control the angle can be ordinary transport. The cutting of polymer pipes is also made by the usual hacksaw with a finely cloth.

Cut pipes in the process of working with these installation elements is very often. A popular tool for such cases is the so-called Bulgarian. With this tool, cut directly and at an angle

The most frequent need for mounting becomes cutting water, sewer and ventilation pipes at an angle of 45º.

Gallery of images

By installing the pipeline, it often has to cut the pipe at an angle. Moreover, the angle must have exactly the degree that is necessary for the design. With improper corner manufacturing, it is impossible to make exactly the size of the pipeline that was supposed to be performed. For example, a pipe when installing will turn to 45 degrees, therefore, it is necessary to know how to cut the pipe under 45 degrees. To do this, we will need marking tools, a bulgaria or a hacksaw for metal.

One of the simplest methods is in the markup of the angle using a sheet of paper. Square sheet is strictly diagonally. We take the pipe and turn it with a folded sheet so that the edges of the diagonals are against each other. Thus, on the smaller side of the leaf, we turned out an angle of 45 degrees. We take any marking tool and place the place of the future side of the pipe. In order for the markup randomly erased, you can use narrow tape. This method of markup is convenient for a long pipe of a large diameter, and the location of which is located somewhere in the middle.

Use water tank

What if we are dealing with a small diameter tube, and it is necessary to cut a pipe at an angle somewhere near the edge? A deep tank filled with water will come to the rescue. Before starting work, you must calculate the angle of inclination and to make the tank on the tank. Next, we still have only gently lower the edge of the pipe into the water and tilt it to the tank mark. I pull out the pipe, mark the line of contact with water, and boldly cut on the markup. This method is good when marking a large number of pipes. A ready-made pattern from water tank will speed up the process of our work.

Computer program to help

I would also like to consider the markup method using a computer program. This is a rather complicated method for those who are not used to working with a computer. It requires a PC knowledge, the availability of programs for sweeps and drawings. We begin work with the performance of the drawing with an indication of the size of the circle and the slope. We make the so-called virtual template.

Then, using the printer, print an image on a sheet of paper. The larger the diameter of the pipe, the more there will be sheets with marking. Scissors cut out all parts of the drawing and with a tape, glue them. The finished pattern is applied to the pipe, and on the edge of the paper make marking. This markup method is considered one of the most accurate. If there are no such programs on the computer, you can use the Internet. On the network you can download molds for marking. It must also be printed on the printer and cut. Ready leaps wrap around the pipe and perform marking.

If profile pipe

But, for example, we have a profile tube, not a round. The hand markup of the profile pipe can lead to a large error. The best way out of this situation will be a manufactured pattern from the same profile of larger diameter. Take a small segment of the profile pipe and with the help of the tilter, we note the angle of 45 degrees. We cut off the marking of the grinder and grind the edges so that when working does not hurt about burstles. Further, we can only insert a smaller diameter profile into the template and, making the markup, cut it off.

In this article, we looked at how to cut a pipe under 45 degrees. Taking advantage of one of the above methods, make markup and make a cut. For a more flat cut, it is better to use the grinder. With cutting welding, experience will be required, otherwise it turns out irregularities. In the extreme case, you can use the metal hacksaw. Currently, there are many different devices for cutting pipes at an angle, but their purchase requires excess costs. It's easier and cheaper to make a template once, and use it as needed.

Video

Thanks to this video, you will learn how to cut a pipe at an angle of 45 or 90 degrees using a computer program:

Cutting a profile pipe with a fixture for cutting pipe under forty-five degrees:

The metal is the material, to work with which the angular grinding machine was originally intended. Now with its help, reinforcement rods are cut, different metal sheets, pipes of various diameters, brick, concrete, stone, tile and other building materials. Due to the presence of various Bulgarian nozzles also makes it possible to perform polishing and grinding the surfaces of products. Metal cutting with a grinder is one of the main, most frequent works. To reduce the likelihood of injury, it must be performed correctly, with strict compliance with the requirements of general and personal safety.

Bulgarian refers to the discharge relatively hazardous power tools. You can get injury from the scattered disk or dropped out of the hand tool. In both cases, the danger is associated with a high speed of rotation of the electric motor of the device.

To improve the efficiency of the work of the grinder, expanding its functionality, in practice such additional devices:

tripods;
clamps.

Their use allows you to improve the quality of sawing metal blanks, improve the accuracy of the process. It is also improved by working conditions from the security position, its performance increases.

Use additional devices allows you to use the tool as a machine intended for execution different species work.

In order to maximize the process of cutting, working on metal an angular grinding machine should be observed in compliance with a number of rules. They are conventionally divided into preparatory and main (working) events.

Before cutting, it is necessary to carry out a number of manipulations.

If possible, the sawn material should be pre-secured, for example, in vice to remove the possible random moves. Keep processed parts in hands or between knees is prohibited.

Proper job tool

Starting the sawing of any part with the help of a corner machine, such rules should be followed.

Hold the grinder when cutting the metal you need tight, two hands.
Circles can be changed only after complete cessation of their rotation and cooling to an acceptable temperature, turning off the power tools from the supply network.
Do not put a working tool for land or table (not to release it from the hands).
Required periodically about 5 minutes stop for restand that the disc is cooled.
It is necessary to constantly monitor the condition of the cutting circle, not allowing it to pinch it with the edges of the sawing blank.
Do not leave an unattended tool included in the network.
Use only discs suitable sizespecified in the instruction manual of the device used.
Work better to perform on a flat surfaceso that the position of the body is stable.
To ensure that the power cord is away from the rotating circle, sharp faces heated more than 100 degrees of objects.
Movements that are not directly related to sharp must be performed only with the power tool off.
It is necessary to be located on the side or behind the tool, performing work with your own hands so that parts of the body are not in the plane of the cut.

When the cutting of metal with a grinder is over, you should wait for a complete disk stop, disconnect the power cord from the network. After it is recommended to make sure there are no signs of fire. During the cutting of materials, right-hand it is properly held by the handle of the device in the area of \u200b\u200bthe on / disconnection button with the right hand. Left hand At the same time, it is located on a knob screwed on top into the body of the power tool.

It is unacceptable to perform work using a grinder in a strongly tired condition, or under the influence of alcohol, psychotropic or drugs.

As for the question of which way, the disc turned on the inclusive of the grinder should rotate, then there is no unambiguous response. The operational instructions indicate that the first option is correct. This is due to the fact that the resulting sparks fly to the opposite direction from the operator, without bringing harm. Also in the direction fragments of the circle, if it splits into pieces.

But in the case when the rotating "on itself" disk occurs, the tool will fly to the operating one. For this reason, many experts prefer to cut the metal so that the circle rotates "from Himself." Combined power tools will fly in the opposite direction. This reduces the likelihood of injury, and from the flying sparks of the user will protect clothing, shoes and gloves.

Bulgarian sheet metal cutting

To cut the metal of different types and thickness, appropriate cutting circles of different thickness and diameters are used. The algorithm for performing sheet sawing is next.

For cutting with the help of the grinder, the sheet metal is pre-laid on a flat surface.
Marked with chalk (marker) The exact dimensions of the cut fragments on the surface of the sheet.
There are sawing according to the marked lines, without changing the angle of the initial slope of the disc to the working surface, so that it does not occur in the enclosure and breakage of the power tool.

If the sawing skills of the sheet metal are missing, it is recommended to pre- stretch on gentle material - It will give the opportunity to feel the work of the tool.

It is necessary to take into account that more effectively cuts the metal bottom of the bottom of the disk.

Performing a cutting sheet of metal, such recommendations should be considered to obtain a qualitative result.

To improve cooling, the place of feeding is required. waterthat will also increase the use of the circle.
It is worth starting to cut the metal only when the disk rotates: it is impossible to turn on the tool if the fixed circle comes into contact with the surface of the workpiece.
To cut tin (thin sheet metal) or cut different geometric shapes, it is more convenient to apply small, produced circles ("Strokes").
Press the Bulgarian with a significant effort should not: cutting should occur almost only under the eigenvalue of the USM.
If the cutting wheel stops in the slot (when the power tool is disconnected), then it is possible to renew work only after it is extracted.

If the sawing sheet occurs slowly, it follows change the working nozzle. Excessive load on the aubliformal machine with a cutting metal will lead to its overheating or jamming the rotating circle.

Cutting a round hole in a metal with an ushm

In practice, it is often required to cut a circle in the metal, and only an angular grinding machine is available from the tools. But it is quite enough for this purpose. The algorithm of action is next.

Draw a circle circle on the metal surface either by a pre-made paper (cardboard) template with chalk or marker.
Holding a grinder at an angle to the surface of the sheet, perform a preliminary marking incision of the metal according to the circuit marked, producing short disk movements (saw small segments).
Then, moving the nozzle in the same way, deepen the slot to complete cutting.

You need to cut on the external circuit contournot to reduce the size of the circle. If its diameter is small, then saw, touching the metal disk at points (without the longitudinal movement of the nozzle). The round hole will be with a slash cut, as well as with some minor flaws (they depend on the skill of the worker). After it, if necessary, processed.

The whole process cutting the round hole in the sheet metal using a special device is shown in the video:

Features of working with thick metal, copper, cast iron, aluminum

When it is required to cut a thick metal into separate fragments, it is recommended to additionally perform the following actions:

constantly cool the plot of metal contact with a disk using cold water Due to the strong heating of the space of the slot;

produce all the cuts are only straightforward;
different curvilinear contours should be cut into separate straight segments of small length, deleting unnecessary parts;
fully sawing the workpiece is needed in a few approaches, with each subsequent deepening slot;
if you want to cut the corners, foreign beams, channels, rails, then each of their structural parts are poured separately.

Cutting cast iron, stainless steel, as well as non-ferrous metals, for example, aluminum and copper, is carried out using special circlesdesigned to work with these materials. All necessary information information is contained in the marking of these products deposited from their side. At the same time, the circles are distinguished by the composition of the fillers:

in the additive, the superproof material is capable of cutting alloy steel;
other applies soft binding substances.

The cutting of the stainless steel by conventional metal discs is prohibited, because their composition includes substances that lead to accelerated corrosion of the cut. Aluminum and copper are very viscous non-ferrous metals. They are sawed with a grinder, watering kerosene The formed disk slot. This requires comply with the rules of fire safety.

Cutting pipes from different metals is a requested operation during repair and construction work. Cut products accounted for when installing sewer and heating systems, plumbing lines. In this direction, Bulgarian copes well with various tasks. Discs for work are chosen by the material from which the pipe is made.

The use of an angular grinding machine makes it possible:

pump pipes at different angles, for example 45 and 90 degrees;
cut the products of large diameter;
exactly cut the profile (rectangular or square section) pipe;
produce longitudinal cutting of tubular blanks;
cut pig-iron pipes;
cut thin-walled tubes.

If you need to cut a large diameter tube, the use of a 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, divert only sweating parts. If you cut into the center, then the edges of the cut will be covered with a edged circle, which will lead to the encoding of the tool and possible injury.

Experts not only cut pipes from different materials under right anglesbut also cut into them the holes required forms. Work with profile and round blanks is carried out in a similar way, with the obligatory compliance of safety regulations.

Peeling pipes at different angles

Cutting at an angle of 45 and 90 degrees Round and profile pipes fall when laying various communications. In any case, it is necessary to smoothly dig a pipe to the items that need to be connected, the most connected to each other.

Cut at an angle of 45 degrees The pipes of the cylindrical cross section are carried out as follows:

take a regular square paper sheet;
fold it exactly diagonally;
this template is turned around the pipe;
with a chalk or other marking adaptation, a future cut line is applied;
clean the pattern;
clamping the workpiece in the vice;
cut the marked fragment of the pipe.

When the template is applied, 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, Pipes simply turn around in a circle (cylindrical) or around the perimeter (profile) sheet of paper. After that, the cut line is marked. Also, it is possible to place a profile tube very simply using a conventional carbon.

If it is necessary to cut at an angle of 45 and 90 degrees, a significant amount of profile pipes make appropriate patterns from this material, only a larger cross section. This allows you to perform the required measurements only once. At the same time, the initial markup use a construction kit, or transport. When the template is made, covered billets insert into it, noting the cutting line. Then there is sawing.

Templates are manufactured for other angles. This method increases the efficiency of labor.

Features of cutting iron and thin-walled pipes

Cast iron is fragile material. To cut down cast iron pipe Bulgarian, act in such a sequence:

celebrate the cut line;
