Aluminum cutting on plasma features.

Cutting durali. slabs, sheets, circles, rods.

Many aluminum cutting the aluminum is offered by many, but only in our company is it really beneficial to the client. For several reasons: the whole process is automated, which allows guaranteeing the quality of cutting, the equipment can work in continuous mode for wholesale orders. In addition, the deadlines are clearly withstanded. And all this at affordable prices, with the ability to order operational delivery of finished products.

Since laser cutting of aluminum is one of the methods of processing, it is most often used. With its help, it is possible to get a neat, clean section of the metal, economical cutting of the sheet, high performance and saving time, which will affect the final price of blanks.

Features of plasma cutting aluminum

Aluminum plasma cutting. ideal option to get high quality cutting of non.ferrous metal.

At the same time, only inactive gases are used for the formation of plasma necessary for the processing of aluminum sheets and its alloys: hydrogen, argon or nitrogen.

Active gases, such as air and oxygen, are designed to form plasma for cutting black metal.

With the use of compressed air, aluminum and aluminum alloys are treated with plasma cutters, provided that the thickness of the products does not exceed 70 mm.

It is not recommended to use a gas mixture combining nitrogen with an argon for plasma cutting aluminum, as it is designed for cutting 50 mm highly alloyed steel.

The use of pure nitrogen gas is possible for cutting aluminum with a blank thickness up to 20 mm.

But nitrogen in combination with hydrogen will allow you to treat aluminum and its various alloys, with a thickness of 100 mm.

Argon gas with hydrogen can be used for cutting aluminum materials, with a thickness of more than 100 mm.

At the same time, hydrogen in argon gas should not be more than 20%, that it is good to affect the stability of the burning arc.

Plasma cutting

The formed plasma stream removes particles of molten metal from the surface. The speed of cutting depends on a number of factors, among which:

You can cut aluminum using plasma manually, but more opportunities for the user gives a mechanized. Its advantages are high performance, saving material. The deficiency is manifested at the end of work. it is necessary to process the edges frozen after cooling the area of ​​the cut.

Types of plasma cutting

There are several classifications of plasma cutting and welding. Depending on the equipment used, welding may be:

  • manual, semi.automatic and fully mechanized;
  • impulse and point;
  • with filler wire and without it;
  • using a penetrating or non.flowing arc.

Plasma welding is classified by current:

Depending on the variety of the material used to obtain a gas stream, plasma cutting occurs:

Simple metal cutting provides for the use of air (or nitrogen) and electric current. Due to the limited length of the electric arc, this technology is acceptable only for processing soft steel.

When cutting metal products using a mixture of two gases, the first is designed to obtain plasma, and the second acts as a protection from the effects of atmospheric phenomena.

Plasma cutting using water in the photo and in reality is similar to the previous technology. The only difference is that water is used instead of protective gas. Thanks to water, more high.quality cooling of the nozzle of plasmoron and metal occurs. This improves the quality of cutting.

Depending on the material that is subjected to processing, holes are made in different surface with plasma and cut:

Settlement technology is plasma cutting of sheet metal. With its help, you can cut any material (for example, bronze, brass, copper, titanium and their alloys). The peculiarity of the method is the need to take into account the thermal conductivity of the metal. With high thermal conductivity, a sheet with a minimum thickness is succumbing to the processing.

Plasma cutting using water

The cut of metal products with plasma using water is becoming increasingly popular. This is due to the following reasons:

  • Sanitary and hygienic working conditions improve.
  • The maximum quality of the edges of the processed surface is achieved.
  • Thermal deformations of metal are reduced.

There are three ways to use water:

During underwater cutting around the plasma arc, a protective screen of water is created. The screen density is adjustable using a special nozzle, which is attached to plasmoron. Particles of metal and slag formed during cutting settled at the bottom of the container.

Plasma cutting under water eliminates the appearance of harmful secretions and smoke during the operation of plasmoron, reduces noise, does not require the use of a protective mask from bright radiation. The disadvantages of the method are low performance with high electricity consumption and difficult control over the process.

In the second method, the formation of the working arc of plasma is carried out using a water flow. To swirl water, a channel located between two nozzles is provided. Water is supplied to plasmotron without gas.

The advantages of this technology are the high quality of the edges and the preservation of the natural color of the metal. But there is also a significant drawback: a complex creation of an arc (only graphite electrodes are used for these purposes that wear out quickly).

The cutting of metal with a small amount of water into the air (or nitrogen) plasma has received wider use. At the same time, water should not in contact with gas, since this is fraught with the destruction of the nozzle and electrode. For this reason, water is supplied to the canal, and gas. into the cavity of the nozzle.

Under the influence of high temperature, the water in the channel evaporates and decomposes into oxygen and hydrogen. The sealing and lengthening of the electric arc occurs. As a result, the driving force increases for the transfer of energy to the cut point, and the molten surface is removed more efficiently.

Plasma cutting with water injection in a small amount reduces the bevel of edges and leads to a decrease in thermal deformation of the metal.

Plasma cutting stainless steel

This metal processing method is based on the melting of stainless steel due to the energy generated by a compressed arc, with the further removal of particles with a stream of plasma.

Plasma cutting stainless steel can be carried out using air, pure nitrogen or nitrogenous compounds. At home, air-plasma sharp. About installation for such cutting, look at

Metal cutting is carried out according to the following scheme:

With plasma cutting stainless steel, two types of energy can be used. The first type of energy comes from the plasma column with the occurrence of a torch. The second type of energy involves the use of electrode spots of one arc.

It is advisable to use nitrogen-hydrogen composition and pure nitrogen in the case of placing the processed edges of stainless steel in an aggressive environment or when exposed to high temperature metal.

Plasma cutting of cast iron

Plasma cutting of cast iron is the best option for large volumes of work and is used by heavy industry and metallurgy enterprises, where cast.iron scrap accumulates. This method is characterized by efficiency and speed in comparison with sharp cast iron using angular grinding or gas cutting.

Plasma cut in cast.iron blanks can be made up to 20 cm deep, and the remaining metal is used in the future without additional processing. In most cases, these works are performed on plasma cutting machines.

When cutting cast iron with plasma, a working arc is used, which has a direct current of direct polarity. The processed metal and electrode from tungsten are involved in its formation. Under the influence of the gas out of the nozzle, an electric arc is ignited, which penetrates into cast iron.

Plasma cutting of aluminum

Plasma cutting of aluminum is used in cases where it is necessary to make high.quality holes, curly cuts or process complex bends of parts. When cutting, the thin layer of metal from the aluminum surface occurs during. The resulting cut has a clear circuit and a flat fishing line for a trimmer.

When working with aluminum, it should be borne in mind that this metal in a molten state is able to actively absorb hydrogen. For this reason, thinner material (up to 2 cm thick) is cut using nitrogen. For processing using plasma cutting products more than 2 cm thick, you need to use the nitrogen-hydrogen mixture. With insufficient hydrogen content, the cut surface is additionally saturated with this substance.

Metal plasma cutting technology

The question may arise that it is better. good laser processing or plasma cutting of the metal? It is difficult to give a definite answer to this question. Each of these technologies has its own advantages and disadvantages.

The main advantage of plasma cutting is the ability to cut metal of large thickness. This quality is especially valuable when plasma cutting of large diameter pipes is carried out.

For the correct implementation of the process, the following parameters must be observed:

  • nominal equipment current;
  • torch clearance;
  • the speed of the apparatus;
  • cut width;
  • The angle of inclination of the edges.

The nominal current strength affects the period of operation of the cutting device. When processing metal products, it is recommended to use current strength not exceeding 90-95% of the nominal indicator.

On the device, current strength can be adjusted depending on the type and thickness of the workpiece. To melt 1 mm steel (cast iron) requires 4 A, aluminum. 6 A. If it is necessary to cut a sheet with a thickness of 10 mm, then for steel the optimal current strength will be 40 A, for aluminum. 60 A.

The optimal flavor indicator is 1.5-10 mm. When cutting the metal, it is necessary to maintain a constant gap, otherwise you will get a poor.quality incision with defects. Excessive decrease in the gap is fraught with premature wear of the electrode and nozzle of the apparatus.

The technology for working with plasma cutting involves compliance with the optimal metal cutting speed. If the speed is too low, this will lead to an increase in gas flow rate. Too high speed will cause a wavy cut line to get.

The width of the cut depends on the diameter of the nozzle (the larger it is, the wider the fishing line for the trimmer will turn out). The adjustment of this indicator is carried out by shifting plasmoron to the desired distance.

A small torch clearance, a large consumption of a plasma.forming component, low current strength, high cutting speed are the causes of a narrow cut.

The burner of plasma cutting should be directed to the cut surface at the corresponding angle. If everything is done correctly, the angle of inclination of the edges will be less than 5º (this corresponds to the norm).

Laser cutting

It is carried out by the influence of the laser beam formed by the high.power equipment. Laser cutting of aluminum is considered the most popular method for a number of reasons:

  • The minimum of time goes to metal processing;
  • saving material;
  • almost complete absence of surface defects;
  • Laser is easy to cut even complex contours (sharp angles, diameters);
  • Modern attitudes are easily adjusted to certain conditions (for example, under the thickness of the sheets);
  • Deformations of the material are excluded.

Cutting aluminum beam-laser is possible on devices of solid-state and gas type. The latter are considered preferable, since they work continuously (the very first. only in impulse mode).

In parallel with the laser beam, an air flow is brought to the processing site, blowing the molten pieces of metal from the edge. This is how the surface of the surface at the output is achieved.

Experts recommend that laser cutting at low speeds to reduce the probability of deformations to zero. For the same purpose, they are advised to use nitrogen.

Working with installations is elementary. the programs are set in accordance with the drawing, the equipment is launched, and the user is waiting for the end of the work. In addition to minimizing the use of human resources, the advantages of laser cutting are electricity saving, as well as the low cost of equipment (compared to hydro.carbrane). There are few disadvantages, but they are:

  • key element. laser; With its breakdown, all the equipment becomes faulty, and the work rises;
  • The speed of cutting is high, but unstable;
  • A prerequisite. the thickness of aluminum does not exceed 20 mm.

Milling processing

The uniqueness of the method is that work is possible with complex surfaces, in t.h. With screw. Be sure to configure milling equipment precisely for work with aluminum, that is, choose the type of cutter and the frequency of its revolutions in accordance with the recommendations.

Modern CNC machines and the possibility of 3D design are not inferior to laser and plasma devices in terms of cutting accuracy. They are used when creating cast forms, volumetric products of their aluminum, complex structures. However, there is a lack of work with equipment-the risk of deformations and the appearance of defects on the surface due to high plasticity of the material is growing.

For cutting aluminum, tape and disk saws are suitable. The advantages of the first:

The design of modern devices includes useful devices, including a rotating saw frame, a thread tension meter (tape), a variator for a smooth change of cutting speeds, a system of cleaning a saw canvas. The quality of the equipment is comparable to laser and plasma, only the master will save a lot (with money, work and space).

aluminum, cutting, plasma, features

Ribbon saws allow you to cut an aluminum profile with a diameter of up to 300 mm with an error of less than 0.5 mm. Therefore, they are used even at home.

The second type of saws used in aluminum cutting is disk. They are divided into front and cutting down, they may look like a floor or desktop, have one or two working heads. In devices of the middle price range there are clamps for fixing the workpiece at an angle. Active element. a disk with a diameter of up to 550 mm. should have diamond spraying on the teeth and indication that it is suitable for cutting aluminum.

Advantages of work with disc saws:

  • Modern installations guarantee the security of the operator during operation;
  • automatic cutting is possible;
  • smooth supply of the cutting element;
  • The presence of waste compartments.

Disk material. high.speed steel (with hSS marking). Some installations allow turning the workpiece to an angle up to 45 degrees for ease of work.

Guillotine cutting

Guillotine installations are limited functionally, since they make only a straightforward cut. advantages; Among them are the speed of processing, ease of service, durability.

Devices are known as “angular grinding”. It is worth noting right away that it is difficult to cut aluminum with an instrument, since it belongs to soft, viscous in structure. But the processing of the material is still possible, it only requires specific actions.

For example, with a cut of thick aluminum sheets, kerosene is dripped to the cut place so that the cut.out disk does not bog out in the metal. It is also necessary to buy a circle suitable specifically for aluminum; Otherwise, the effectiveness and safety of work will decrease.

Advantages of cutting angular grinding. speed, efficiency, relatively subtle cut width. It is important for the user to remember that the effort is made only in the radial direction.

Aluminum is a special material with specific properties, so cutting technology is not selected as for the same steel. For the user, the choice of processing method, process control, proper setting the initial parameters (when working with automated installations) are important. Errors are unacceptable. plastic and viscous aluminum will not forgive the blanket.

If you know other effective ways how and what to cut aluminum, share your knowledge in the discussion to the material.

The final setting of the process

When determining which process to use aluminum, experts should determine the results that are the most important for them. For some production, performance will be the most important criterion, and for others. the purity of the edges. Many plasma systems are capable of cutting several processes, so they can be accurately configured in accordance with the requirements for the result.

For example, a plasma system can cut aluminum with a thickness of 5 mm at various parameters: at a current force of 45 A to 260 A and combinations of air/air or argon/helium gas. Various currents and gases provide various results, such as increasing performance, good processing of edges or hard tolerances.

The enterprise can be cut using an argon/helium at 130 A, if you need a good balance of performance and quality, as well as the edge of the edge. If high speed is important to the manufacturer, and it plans to do subsequent processing, then you can work at the maximum current as quickly as possible. Users themselves combine the parameters, and their solution is usually dictated by the priority of the desired results.

Cutting a metal sheet with a plasma apparatus

Plasma cutting of metal can be carried out using a plasma jet. This method is called plasma. Cutting tool. plasma. is an air.

It is heated to a very high temperature, after which it is in an ionized state. The electric arc is lit between the electrode and the metal sheet.

Plasma appears from gas, which enters the nozzle of the apparatus. Plasma has a high temperature.

It can reach 30 thousand degrees, moving at a speed of up to 1,500 meters per second. Such a stream can cut a sheet in which the thickness is 100 mm.

The principle of operation of the apparatus

The machine acts on the following principle: a short circuit occurs between the sheet and the nozzle, as a result of which an arc appears. Gas that gives the instrument to the section, cools the surface.

The environment in which the plasma appears is divided into two types: active, inactive. The composition of the active one includes air, oxygen.

It is used when working with ferrous metals. Inactive contains nitrogen, hydrogen, argon, water vapor. It is used when cutting alloys, non.ferrous metals.

The purpose of the cutting arc is to convert electric energy to thermal.

The arc voltage can be recognized by the size of the device, current strength, components that are part of the gas, the distance from the apparatus to the base sheet.

These parameters can be determined by the temperature by the section of the pillar and along the axis of the arc. During work, it will change.

High temperature helps plasma crash into a cut metal.

If the power, the temperature of the arc correctly correlates with the thickness of the sheet, then the plasma will penetrate through the entire thickness of the metal and make the incision. In this case, the cut is vertical, so the machine is universal.

During work, you should pay attention to the speed. It should not be higher than the permissible norm. Otherwise, the material will not be cut to the end.

It is important to know: the principle and technology of plasma cutting metal

The plasma cutting of the metal has advantages:

  • Plasma stream is universal. With this method, you can cut any type of metal;
  • Cutting is very accurate;
  • Slices after revealing high quality, they do not need additional processing;
  • A machine to cut metal with a plasma, is able to cut a blank of any geometric shape;
  • The cutting of a metal sheet in this way is an economical process, since it is not necessary to use expensive types of gases. acetylene, butane, propane;
  • When cutting a sheet using a jet of plasma, you do not need to use cylinders, so all processes will proceed safely;
  • The plasma machine does not emit harmful substances into the atmosphere during operation;
  • Plasma can be cut the material that is covered with paint. The surface does not need to be first cleaned, since the action of the plasma on the surface is minimal;
  • The metal will not be deformed during cutting if this machine is used.

Long-EZ N916WP. Plasma Cutting 6061 Aluminum Instrument Panel


Metal plasma cutting is the technological process of metal processing, in which cutting sheets or volumetric products into separate parts is performed using a jet of plasma. ionized gas warmed up to a temperature of 5000. 30,000 ° C. Active and inactive gases are used to carry out plasma cutting of the metal. Air and oxygen include the first, they are usually used in cutting cast iron, high.carbon and alloy steels. Nitrogen, argon, hydrogen is used for cutting non.ferrous metals and their alloys. aluminum, titanium, bronze, brass. Plasma of inactive or inert gas avoids the formation of oxide films on the edges of the products.

The use of plasma cutting

Technology is used in installation, production, construction work. With the help of “plasma”, figured blanks for interior, facade, enclosing structures are cut out. Unlike other cutting methods, plasma cutting is applicable for most structural materials (not only metals) and is characterized by high intensity and universal geometry of the processed surfaces.

Technology and equipment

The cutting of the metal is carried out under the thermal and kinetic effects of the jet of hot ionized gas, which successfully replaces the mechanical, laser or gas cutter. The stream comes out of the nozzle of plasmotron under pressure of up to 5 atmospheres and is supplied to the cutting site at a speed of 500 to 1500 meters per second.

Metal in the zone instantly melts, boils or burns out, and the created pressure and intensity of the plasma supply blew the separated components from the place of processing, forming a clean, neat fishing line for a cutting trimmer.

Plasma. the fourth aggregate state of a substance into which the working gas turns in an electric arc.

To carry out cutting work, plasma cutting of direct and indirect effects is used. In the first case, the Voltova arc is ignited between the electrode and the surface of the processed metal, in the second case, between the electrode and the nozzle plate.

Plasma cutting equipment includes the following structural elements:

  • A power supply source or direct current, or an inverter that converts an industrial three.phase current of 380V into a constant.
  • Worker.
  • Compressor for pumping a working pressure.
  • Plazotrotron, consisting of a nozzle, electrode and isolated handle with increased heat resistance for manual control of the technological process. The nozzle is equipped with an air cooling system.

For serial plasma cutting of large.sized blanks and thickness, stationary plasma cutters with automated control are used. They use liquid cooling of the nozzle and the cutting zone.

Pros and cons of plasma cutting

Among the technological and economic advantages, with which the plasma cutting of the metal favorably differs from the hydro.carbrane, gas.flaming and other cutting methods, include: include:

  • High performance-the timing of work is 4-10 times shorter than with other types of cutting.
  • Universality. at the production site “PTK Engineering”, you can cut metal rolling and blanks with a thickness of up to 200 mm with absolutely any configuration and geometric shape. The cutting fishing line can be straight, curly, curved. The temperature and kinetic energy of the plasma jet are such that they cut the hardest and tighter materials, like butter. Equipment for plasma cutting, which is disposed by masters of PTK Engineering, allows you to carry out a one.time cutting operation with the same success and carry out a typical operation many times.
  • Economy due to high performance. The consumption of working gas and electricity during cutting is much cheaper than the consumption of fuel gas during gas.fingered cutting.
  • Relative safety. there is no risk of ignition or explosion of combustible gas. In this case, in any case, strict adherence to the rules of welding and firing work is necessary.
  • Slight local heating of processed parts due to a short processing time. With plasma cutting, the parts are almost not subjected to thermal deformations, the fishing line for the trimmer cut is free from oxides, roughness and other defects.

The only relative disadvantage of plasma cutting of the metal is that when the high.accuracy of processing is required, the finish is required. The fact is that with plasma cutting it is impossible to achieve the absolute parallelity of the cut edges. they inevitably converge at an angle of about 5 degrees, and the thicker the sheet of metal, the more noticeable is.

That is why, with almost unlimited capabilities in thickness, the method is more often used on products and rental of small and medium thicknesses.

When performing plasma cutting, irregularities are possible along the edges of the cut line. They are able to eliminate finishing metal processing, which is available to all customers of PTK Engineering LLC.

Plasma cutting. the technology of separating metal blanks by thermal effects. Simply, the metal is cut with a plasma stream. The stream itself is formed as a result of the supply of electric current to the gas transmitted through the nozzle of plasmoron. Under the influence of current, an electric arc occurs, which is also called a plasma arc.

Plasma cutting technology

The following components are necessary for plasma cutting:

During operation, compressed gas is used, which is supplied to a narrow nozzle under high pressure. Passing through the nozzle, the gas is processed with an electric arc created by the electrodes. The arc sets fire to gas, as a result of which a plasma stream is created with a temperature of up to 20 thousand. To. Such a temperature is enough to cut blanks of any thickness. Under the influence of the arc, the metal melts in the cut area. He does not have time to harden, as it is blown out under a strong pressure.

Varieties of plasma cutting metal

This cutting can be performed by arc or stream. With an arc method, the metal itself is an element of the electrical circuit and is involved in the creation of an arc. With jet cutting, the arc is formed only by electrodes.

aluminum, cutting, plasma, features

In addition to the method of creating an arc, this process is characterized by the principles of work. There are three varieties of cutting:

  • ordinary, in which nitrogen or air is used to form arc. This method has a small arc length. It is suitable for processing soft or low alloy steel. When using oxygen, a fairly even cut with a minimum m nitrogen is obtained;/Li
  • Protected, carried out using protective gas. Special gas is needed to protect slices from oxidation under the influence of atmospheric air. The thin gas layer significantly improves the quality of the cut;
  • using water. Water, like special gas, protects the edge from negative external influences. In addition, it absorbs harmful evaporation and cools the cutting equipment.

Types of plasma cutters

Plasma cutting equipment is inverter and transformer. Inverter consumes little energy and has compact dimensions. But it is not intended for long.term work and is afraid of voltage drops.

Transformer plasma cutters. professional equipment intended for long.term use and non.fearful voltage jumps. It is more massive and energy consumption.

aluminum, cutting, plasma, features

There are other parameters inherent in all plasma cutters. For example:

  • The power of the unit. The thickness of the processed material depends on this characteristic;
  • metal cutting speed;
  • The material of the manufacture of the burner;
  • The possibility of focusing. The function of arc focusing is present only in high.precision systems with maximum cutting quality. Using such systems, you can minimize the width of the cut and make complex parts.

Advantages of plasma cutters

Compared to laser metal cutting technology, plasma is distinguished by many advantages. The main of them:

  • Working with any metals. This technology is suitable for ferrous, non.ferrous and refractory metals. over, plasma.cutting can be cut without even containing iron materials. For example, ceramics, plastic, wood;
  • high metal processing speed;
  • the ability to create blanks of any form. You can even engage in an artistic harsh one, provided that the equipment suitable for this task is used;
  • excellent cut quality, regardless of material thickness. This characteristic has restrictions. The permissible thickness of the material depends on its thermal conductivity. When working with metals with high thermal conductivity, you can cut only thin sheets. Otherwise the material will melt faster than cut. The result is a sloppy slice;
  • the possibility of cutting blanks at an angle, without pollution and defects;
  • the minimum amount of harmful substances thrown into the air during operation;
  • Reduced burning time. Plasma cutting does not require preliminary heating of the material. Therefore, the burning occurs much faster;
  • Lack of deformation in the processing zone. Also, the cutting effect will not be in the field of cutting;
  • Safety of use. The main danger when cutting metals is in gas cylinders that may explode from a blow or sparks. Plasma cutters work without gas cylinders. To ensure the safety of work, it is enough for the master to put on protective overalls and use the equipment correctly.

Necessary power sources

Metal cutting units can work from various power sources. Inverter plasma cutters do not require connection to additional equipment. They eat right from a conventional power grid.

Transformer units. more powerful devices. They need to connect to the transformer. When working with such plasma cutters, you need to increase the rate of current with a step method.

How manual plasma cutting is performed?

Manual devices are simple in management and do not require specific skills. They are used even in everyday life for amateur purposes. The main thing is to clearly follow the instructions in the process of carrying out work. This instruction includes the following points:

  • Selection of a suitable place for installing the unit. The right place is considered to be suitable from other items. During operation, the air should easily go to the apparatus from all sides;
  • Assembly of plasma cutters and connecting cables to it according to the manufacturer’s instructions. Your safety will depend on the correct connection of the connection;
  • Connecting equipment to the mains. Hand plasma cutters are connected to a regular household network. They do not require connection to the transformer. But you must remember that these units do not tolerate voltage drops. Therefore, it is better to connect them through a voltage stabilizer;
  • Selection of material of suitable thickness. Manual devices have a slight power and limited switching settings of current strength. Therefore, it is not recommended to go beyond the limits specified by the manufacturer;
  • Turning on the device. After its connection, an electric arc on duty will be formed. Its length should be within 4 cm. The current strength, at the same time, can reach 70 A;
  • The formation of a cutting arc. In the event of this arc, current strength increases significantly and air expenses increase. With the advent of the cutting arc, the duty arc is automatically turned off;
  • Carrying in compliance with the recommendations of the manufacturer regarding continuous operation. Most household units cannot work for more than 30 minutes in a row;
  • You will learn the exact time of work from the instructions for your plasma cutter.

Ultra.precise cutting technologies

Superflow metal cutting is carried out using thermal, thermochemical processing of the material. These include plasma and laser cutting.

The cutting of these methods is based on a narrowly controlled effect on a certain point of the metal sheet with a laser or plasma beam.

The zone at which the point of exposure is located is considered a catalyst for oxidation, which occurs as a result of thermal exposure. It supports it is supported by oxygen at the time of combustion.

Thermal oxidation can be controlled. For this, the nozzle can be moved, respectively, the high.temperature zone will move.

Thus, it is possible to achieve the sheet with a plasma billet or a laser.

If there is a need, then in the same way you can make a hole anywhere in the workpiece. All operations must be performed on special equipment.

Why plasma cutting aluminum should be entrusted to professionals

Many people believe that cutting aluminum on your own is not so difficult, which means that you can save well on this. it is enough to purchase compact plasmores or even build it with your own hands.

But why is it better to turn to professionals?

  • Performing high.quality aluminum cutting is not so easy. Only an experienced specialist will be able to manage the plasma cutting process in such a way as to get a decent result. You can’t replace skill and experience.
  • Good equipment for plasma cutting costs a lot of money and requires constant control and maintenance. If you use this equipment not so often, it will be much more profitable to contact specialists. You will significantly reduce the costs of aluminum processing and the cost of finished products.
  • Plasma cutting is associated using high.voltage equipment and is accompanied by an evaporation of aluminum. Therefore, the work should be carried out in a special, well.ventilated room, in compliance with all safety requirements. Such a premises should be verified by the fire inspection employees. Regular certification is usually required, that is, periodic visits of inspectors.

It is clear that you will get rid of many problems and save money if you use the services of a specialized company. By the way, many of these enterprises are engaged in the development and installation of metal structures, which can also be useful to you. If you contact a really worthy company, you will receive comfortable maintenance, qualified advice and work performed at a high level and taking into account all your wishes.

Plasma and laser machines

The best way in terms of quality and speed, but not suitable for home conditions. Plasmoresis and laser machine are considered professional equipment and are found at metallurgical enterprises. If there is an installation and cutting of an aluminum profile nearby on it, it is possible to use this.

aluminum, cutting, plasma, features
  • Profile cutting takes a couple of minutes;
  • The user only sets up the equipment, the rest does the machine;
  • Reza quality is the best of all ways.

Milling installation

It is important that this equipment is configured by the operator specifically for aluminum work. This is due to the softness and plasticity of the metal. It is also important to choose small speeds of the milling device (from 5,000 to 9000 per minute) and first drip kerosene to the cut area. The feed is smooth, neat, so as not to damage the cutter. Advantages and disadvantages are similar to plasma cutter and laser, but the quality of the processing of the part is slightly worse.

A circular saw

An analogue of a hand saw, but more powerful. It has the following capabilities:

  • performs a longitudinal, transverse, inclined cut;
  • can be sawed from any place of the workpiece (not only from the end);
  • Modern devices prevent overheating, turning off in a timely manner or applying a signal to the operator;
  • The user can choose the speed of work based on the thickness of the workpiece.
  • The durability of the equipment is a disk for working on metal (better. in aluminum);
  • speed of work;
  • maneuverability;
  • the ability to cut at an angle up to 45 degrees;
  • The cost comparable to more suitable analogues (end saws for aluminum).
  • As a rule, the equipment is bulky and weighs a lot than complicates the work;
  • The price will seem high if the tool is bought for one.time work;
  • ).

Circular Saw

For example, the Yilmaz Ky 305 desktop saw. This is a special device for cutting small metal profiles with a small wall thickness. The mechanical clamp fixes the workpiece, the cutting angle is set up to 45 degrees (in any direction), it is possible to choose a fixed angle (0, 15 degrees., 30 degrees and t.D.).

  • allows you to cut larger blanks (up to 130×65 mm);
  • compactness;
  • the possibility of angular cutting;
  • high speed and accuracy of work;
  • Availability of equipment (300 mm saw).

End (pendulum) saw

Structurally resembles previously described, only the working body is not a whole metal, but an abrasive disk, as for an angular grinder. It is considered the best solution for cutting aluminum profiles at home for the following reasons:

  • cut straight, along and under inclination;
  • When working, the user only needs to lower the curtain (pendulum) to the workpiece, and without much effort;
  • reliable fixation of the workpiece in the clamps;
  • the ability to work with long aluminum profiles;
  • there are models similar to disk price range, but more functional.

In confirmation of the latter approval, the Makita LF 1000 end saw was considered. Her characteristics:

The maximum depth of cut. 68 (at 90 degrees.) and 50 mm (at 45 degrees.);

Such a ending will cost the user 60 thousand, but subject to constant work. Otherwise, the investment will not pay off.

  • If the cutting of an aluminum profile is carried out irregularly, a manual tool is enough. hacksaws, corner grinders and even scissors.
  • With constant work, it makes sense to purchase a portable saw, preferably end, since it is multifunctional. Investments will pay off after 2-3 months.
  • For the work of an enterprise engaged in serial production of metal profiles, plasma cutters or laser installations will be required.
