Shaped cutting of sheet metal - technology and equipment

Artistic metal cutting (another common name is figured) is the creation or application of original drawings, inscriptions or other visual elements onto sheets of material. It can be performed using special equipment, most often machines, that allow processing durable and hard materials such as steel and other metals and alloys. To work with such equipment, as a rule, professional skills are not required; it is enough to carefully study the instructions and processing techniques.

The process of figure cutting of metal using a plasma cutting machine MAXILITE 3000

Let's take a look at the MAXILITE 3000 plasma cutting machine in its basic configuration. MAXILITE 3000 is a machine that is used for cutting metal with a thickness of 0.3 to 20 mm with good speed and high quality. The thickness of the metal that our machine can cut depends on the power of the plasma source. The machine has a modular design, so transporting it to the desired location is not difficult. So, we list the main distinctive features of the machine:

• lightweight collapsible frame
• portal made from a rectangular profile, also lightweight
• CNC control rack has a very “grown-up” look
• integrated desktop
• for stable work with thin sheet metal there is a mechanical control of the burner height
• optimal cost with decent characteristics

We can select a device and a plasmatron for you to suit your tasks, for example, you can reduce the size of the desktop, if necessary, and, accordingly, this will affect the cost downwards.

Please note that to operate the machine separately you will need the following equipment:

• exhaust fan with an impeller of at least 200 mm;
• air compressor with a capacity of at least 400 l/min;
• refrigerated compressed air dryer;
• main filter for class 1 air purification from solid impurities, oil and water.

In order to start working, the machine must be correctly installed, connected to power and be sure to properly organize an exhaust hood to remove smoke from particles of burning metal

This is important because a lot of smoke is generated during work, and breathing these fumes is not very good for health. The software with which the machine is controlled is available in the basic version, this is Pure Motion from the Russian company Purelogic

In the following articles we will try to analyze this software in detail, since it is still not as simple as we would like.

So, in order to cut out any detail, you will need to draw it first. You can use any software that allows you to export or save any drawing in DXF format. These can be programs such as AutoCAD, Compass, Corel Draw, etc. They, of course, are not included in the kit.

You will also install the SheetCAM program, with the help of which a special G-code will be generated, which will need to be transferred to the Pure Motion program.

It turns out that the procedure is such that first in a third-party program you draw the necessary artistic element, save it in .dxf format, import it into SheetCAM, save the generated G-code, and then import it into the Pure Motion program and it transfers it directly to cutting table with all necessary actions and coordinates.

You will also need to correctly configure the Pure Moiton program because when working with different thicknesses and metals, the speed settings, plunge height and working height of the torch will also be different. In one of the following articles we will also look at these settings in detail.

Artistic cutting of metal with plasma is performed with a plasma jet, which is used as a cutting tool. After you press the button to start the process of cutting the product, an electric arc is formed (between the metal and the electrode), the ignition of which occurs due to a pulse or short circuit; gas under pressure is supplied from the nozzle; under the influence of an electric arc, it turns into a plasma jet, the temperature of which reaches 30 thousand degrees and the speed of 1.5 thousand m/s. The cutting speed depends on the thickness of the metal, the power of the plasma source, and the complexity of the cut pattern. During the process, the drawing you drew in the program will be cut out of a sheet of metal.

It may seem that working on a CNC plasma cutting machine for figure cutting of metal is very difficult, but this is only at first, as in any other business, at first there will be mistakes, you can’t do without it, but then you will get the hang of it and get an inexhaustible source of realizing the most bold creative decisions.

Implementation technology

Depending on whether the surface being processed is conductive, there are two types of cutting.

1. For non-conductive materials, an electric arc is created between the metal being processed and the electrode. The plasma flow goes directly from the generator to the metal, which is melted by the created arc.
2. For dielectric materials, the cutting process is carried out using a plasma jet. The arc does not interact directly with the metal being processed. The resulting melt is immediately removed (blown out) by the same jet.

A CNC machine is a special programmable device that allows you to cut workpieces according to specified parameters. This method allows the material to be processed at very high speeds. Of course, such a device consumes a lot of electricity, however, the plasma method of cutting metal is considered one of the most economical and productive.

Currently, there are both industrial CNC machines for plasma cutting and amateur plasma cutters for manual work. The former have large dimensions, while the latter allow for more masterful cutting of metal; in addition, their main advantage is mobility. With the help of hand-held plasma cutters, real works of art are created.

The temperature of the plasma reaches five thousand degrees or more, and its speed of movement is more than 1.5 km/s. Therefore, when working with a plasma cutter, it is necessary to observe technical safety aspects and use personal protective equipment.

Plasma cutters use electrodes made of a tungsten-lanthanum alloy. The following are used as plasma-forming and cutting gases:

• oxygen:
• hydrogen;
• argon;
• nitrogen;
• mixtures of the listed gases.

For different variations of materials, operating modes that meet their characteristics are required. The composition of the plasma is determined by the type of alloy and the thickness of the material. The most popular service is cutting metal pipes. Its cost is available to a wide range of consumers and depends on the following indicators:

• thickness of the metal being processed;
• its type;
• the complexity of the parts that need to be cut.

Thermal cutting of sheet metal is carried out not only by plasma. There is also laser cutting of metals.

Laser cutting

The cost of such cutting is much higher than plasma cutting. Laser cutting allows you to process metal material up to 20 mm thick. It is carried out on a special machine, the cutting tool of which is a laser beam.

The machine on which laser cutting of metal is performed is controlled by a computer, which allows the process to be fully automated. Due to the high cost of laser equipment, it is considered economically justifiable to use this method when it is impossible to carry out cutting using traditional methods.

Order for cutting sheet metal

You can place an order for metal cutting in Vladimir as follows:

• Using specialized computer programs, a cutting map is drawn up. It is necessary so that the dimensions of the parts, their configuration, and possible holes are reflected on paper, as in a document. It also allows you to make maximum use of the area of ​​​​the rolled metal sheet to obtain the largest number of parts and serves as the basis for drawing up an invoice for cutting costs.

According to the cutting map, technical specifications for cutting for a manual plasma cutter are drawn up. For a CNC machine, a technological process for processing a part is designed, calculating the trajectories of movement of the working parts of the machine and recording it on a program medium.

Sketches for plasma cutting

Both in the city and in the countryside, the tradition of decorating your own space with original things, made to order or with your own hands, is returning. Expressing your aesthetic needs in decorating your home or garden has become easier with the advent of plasma metal cutting.

Unlike hot forging, which has been used for centuries to create fences, porch canopies, weather vanes, fireplace and stove doors, the plasma cutting process requires less physical effort. Artistic cutting of metal with plasma is a faster manufacturing process, forging, and the design is more delicate and delicate.

Heating the metal to very high temperatures does not in any way affect its technical characteristics due to the short-term contact of the processed material with the flame. Due to this, no sagging is formed on the cuts, which means that the finished product will not require sanding.

The most painstaking work in the artistic cutting of metal with plasma is creating sketches for cutting. Not being an artist, you will have to use the method of enlarging the drawing you like to the required size, projecting it onto a sheet of metal using a light bulb placed in a box located behind the image on paper. This homemade enlarger is used if there is no slide projector in the house from ancient times. The size of the image is varied by moving the pattern towards the beam of light or removing it to the required distance.

Artistic metal cutting can vary in cutting technique. To create a garden sculpture, you need a clear outline of the object. It is better if the cutting takes place in long, clear lines. Also, this method of guiding a cutting arc along the contour of an element is necessary for cutting out large elements in a fence, on gates and other decorative details. Small cuts are created by short "strokes" of flame across a sheet of metal.

Operating principle of a plasma cutter

Equipment for plasma cutting of metals consists of:

• power source - an inverter that converts alternating current into direct current, increasing its frequency several times (a voltage of 220 or 380 V is required for connection, the equipment produces a voltage of up to 400 V and a current of 25–125 A);
• torch – plasmatron with nozzle and power button;
• ground cable;
• compressor (compressed air cylinder).

A plasma cutter works as follows: an electric arc is ignited, into which compressed air enters. When heated, it is converted into plasma, which cuts any metals, ceramics and other materials. The temperature at which plasma cutting occurs is approximately +20,000 °C, which is 6 times higher than during oxygen processing of metals.

We recommend articles on metalworking

• Steel grades: classification and interpretation
• Aluminum grades and areas of their application
• Defects in metal products: causes and search methods

Unlike oxy-fuel cutting, which cuts materials using the pressure of compressed gas coming from a cylinder under a pressure of 10 atmospheres, the operating speed of a plasma cutter is 1,500 m/s. Parts produced using a plasma installation are distinguished by a clean, narrow cut edge and a minimal amount of slag.

Before you think about how to choose a plasma cutter, you should familiarize yourself with the principles of its operation:

1. The plasma cutter nozzle contains a cathode and an anode, between which, under the influence of voltage from a current source, an electric arc occurs. At the same time, the compressor supplies compressed air to the nozzle through a filter drier. Passing through the electric arc, the air is saturated with ions and turns into plasma. Such a duty arc occurs only in a plasma torch.
2. The burner is brought to the workpiece. After the pilot arc closes on the workpiece, due to the positively charged ground cable connected to it, the arc becomes cutting. The length and width of the plasma beam is adjusted by changing the current strength and the diameter of the nozzles used. Cutting is done by moving the torch along the intended contour.

3. At the end of the work, the burner is removed from the workpiece, the arc again becomes standby. Then it is extinguished, but for some time air continues to flow, cooling the nozzle.

How to make a plasma cutter from an inverter - instructions

If desired, any owner can make such equipment with his own hands. However, in order for a homemade plasma cutter to do its job effectively, all the rules must be followed. In such a case, an inverter will be practically irreplaceable, since with the help of this device a reliable supply of current will be ensured. Due to this, there will be no interruptions in the operation of the plasma cutter, and it will also be possible to reduce energy consumption. However, it also has disadvantages: it is designed for cutting material of a smaller thickness than when using a transformer.

Selecting elements

If you decide to make a plasma cutter yourself, then you should prepare the necessary materials and equipment:

An inverter or transformer with the required power. In order not to make a mistake when purchasing this device, you need to tell the seller in the store about the thickness of the material you plan to use it for cutting. Based on this, the selection of a suitable mechanism will be made. Considering that cutting will be done manually, it is advisable to purchase an inverter, which is associated not only with its lightness, but also with its ability to reduce energy costs.

Plasma cutter or plasma torch point. When choosing it, you must rely on the same criteria as in the case of an inverter. The important point here is that direct impact equipment is designed to work with conductive materials, while an indirect impact plasma cutter is more suitable for working with products that are not capable of conducting electricity.

Compressor for air circulation

Here you should pay attention to its power, according to which it should be correlated with other selected components.

Cable-hose package. His task will be to combine all the above-described elements.

Assembly

Even before you start assembling a homemade plasma cutter, it doesn’t hurt to find out whether the components you purchased are compatible with each other. If you have never made a plasma cutting machine with your own hands before, it is advisable to seek help from more experienced craftsmen. After analyzing the power of each element needed, they will give you their recommendation. You should definitely make sure you have a protective set of clothing. You will have to use it when the time comes to test the performance of a homemade plasma cutter. If we talk about the procedure for assembling plasma cutting equipment, it includes the following steps:

At the first stage, it is necessary to prepare all the necessary elements for assembly and protective clothing.

Next, you should resolve the issue with an uninterruptible power supply.

Then you need to take an inverter or transformer, as well as a cable of suitable thickness and electrodes

Pay special attention to the last element, which should be made of beryllium, zirconium, thorium or hafnium. Such materials are considered the best choice for air plasma cutting

Hafnium may also be considered as an alternative because it will provide greater safety to the welder or craftsman who will be doing the work of separating the sheets. The listed elements must be connected to each other in order, the result should be an electric arc.

Next, a hose is connected to the compressor. It is through this that air will flow into the plasma cutting machine. The second edge must be connected to the plasma torch.

Take a small piece of aluminum and test the operation of the device you have made. Pay special attention to the security of connections.

Regardless of whether you plan to make a plasma cutter with your own hands or buy it in a store, you should first study all the models, get acquainted with the principles of their operation and design options. An important point is the type of material that is planned to be cut using this equipment in the future. You can simplify your selection task if you first watch a video that shows the operating principle of a manual plasma cutting machine and the technology for working with it.

Quality of parts

Comparing the quality of the resulting parts and based on the cost of consumables, we can come to the conclusion that laser cutting is more effective than plasma cutting for thinner sheet materials, and plasma cutting for thicker ones. It should be taken into account that operating costs for both types of cutting vary widely and are largely determined by the geometric parameters of the workpiece, the number of holes in it, and the type and thickness of the material being cut.

Gates and fences using laser cutting technology.

When buying housing in a good, geographically conveniently located area, we make sure not only that the layout of the apartment matches expectations, but also the general improvement of the area. The cleanliness and tidiness of the courtyards, the presence of flower beds and playgrounds, the presence of nearby green areas, ample parking - after all, your guests begin to form their opinion about the apartment not from the doorstep, but from the yard. A beautiful and well-kept yard can be called the business card of your apartment - even before looking at your home, a person will already begin to form a positive opinion. However, in urban conditions, the infrastructure and improvement of the area is usually handled by the developer himself, limiting your influence only to voluntary participation in community cleanups and maintaining the original plan in proper form. So even the greenest and most comfortable area will only indicate your selectivity when choosing living conditions, but will not convey your individuality.

Types of artistic metal cutting

Shaped metal cutting is performed in one of four main ways, which are based on the following technologies:

• laser;
• plasma;
• waterjet;
• guillotine

Each technology has advantages and disadvantages. The first two are considered the most modern and therefore progressive and widely used.

Laser cutting

Metal laser cutting uses a powerful laser to process and cut the material. More often, this technology is used on an industrial scale, where the laser beam is controlled by a special computer program. As a result of a narrowly targeted effect, the material in the area being cut rapidly heats up, melts, and then evaporates or blows out. At the same time, the technology makes it possible to obtain a narrow cut with an extremely small area of ​​influence on the surface being processed.

Laser cutting has a number of advantages:

• relatively low level of costs (compared to most alternative technologies, with the exception of plasma cutting) when processing hard alloys;
• the ability to work with brittle alloys that are easily deformed;
• safety of technological processes (when using serviceable equipment);
• absence or extremely small deformation of the material, which is achieved through highly targeted processing;
• the ability to create a wide variety of complex contours;
• no need for subsequent finishing or surface treatment.

Thanks to the peculiarities of the technology, using laser cutting it is possible to create designs of any complexity without requiring additional processing, since the edges and edges are immediately smooth and even.

The disadvantages of laser cutting include the inability to work with aluminum and its alloys with stainless steel. This is caused by the reflective properties of the material. It can only be processed using particularly powerful laser equipment.

Artistic laser cutting of metal is a high-quality way to create a pattern with the least amount of material and time.

Plasma cutting

• an electric arc is formed (between the nozzle and the electrode or between the metal and the electrode), the ignition of which occurs due to a pulse or short circuit;
• gas under pressure is supplied from the nozzle;
• under the influence of an electric arc, it turns into a plasma jet, the temperature of which reaches 30 thousand degrees and the speed of 1.5 thousand m/s.

Plasma cutting of metal has the following advantages:

• the ability to create drawings and figures of any complexity;
• high-quality, clean and smooth cut;
• ability to process all types of metals;
• speed and performance of the equipment used;
• no deformation of the material;
• safety of technological processes (if the equipment used is in good working order).

Artistic plasma cutting can be applied to materials with rust or contamination, which does not lead to deterioration in the quality of processing. Compared to cutting using laser equipment, plasma has greater productivity and a range of materials that can be processed.

The disadvantages of this cutting method include:

• a cone formed on the edge caused by a technology feature;
• slightly larger cutting width compared to laser cutting.

Gate design

Special attention is paid to it during the manufacturing process. The proposed design solutions include:

• Deaf. The canvas is completely closed from prying eyes, minimally decorated with artistic elements.
• Through. The canvas has numerous through decorative decorations.
• Combined (mixed) is the most acceptable option. Organically combines the first two (for example, the upper part is openwork, the lower part is blind).

Gates offer many possibilities for creating a unique design solution.

Automatic cutting

We create our products from sheet metal. The task is to accurately and efficiently cut out the required design on the sheet. For processing, we use metalworking machines that allow us to quickly and accurately create almost any picture. The main working element of the machine is the cutter, which can automatically move over the sheet of metal being processed. The sheet itself is fixed on the coordinate table, and the cutter moves along the X, Y axes of the coordinate table with high accuracy and a given speed. Also, the cutter can rise above the sheet of metal and fall closer to it (along the Z axis). The software sets the cutting parameters and movement of the cutter; this software can be used to produce metal products with very complex geometric patterns. The size of the finished product is limited by the dimensions of the coordinate table. The positioning accuracy of the cutter and the cutting parameters determine the quality of the finished product. When cutting, you can use different (according to the physical principles of their influence on the material) cutters. Waterjet and laser technologies are widely used. Waterjet cutters

They act on the metal with a thin stream of water supplied under pressure containing particles of an abrasive substance.

With this effect, microparticles are torn out of the metal (or other material) and washed off with water. This creates a cut. The water supply speed, the abrasive material itself and the size of its particles determine the cutting parameters.

With laser cutting

The determining factors are the radiation power and the diameter of the laser beam. The laser beam can be several microns in diameter, and in this case the accuracy can be very high.

These technologies have a number of advantages that allow them to be used to solve complex production problems. Our company uses air plasma cutting

. Let's look at its features in a little more detail.

Today metal products are very popular. This is a very durable material that will last for many decades without losing its original characteristics. Due to its decorative properties, metal is actively used in all spheres of human activity. Metal processing often takes a lot of time and effort.

Features of decorative metal cutting

The thinner the metal sheet and the lower its melting point, the greater the risk that by holding the cutting arc a fraction of a second longer in one place, the element may not turn out clear. To create paintings with small, closely spaced elements using plasma cutting, it is better to create on CNC plasma cutting machines.

Plasma cutting can be carried out on metals of different thicknesses. Some devices for plasma cutting provide a flame heating temperature of up to 30,000 °C, and their cutting depth reaches 20 cm. Figure cutting with such equipment parameters can be used not only to create stencil sculptures, but also for convex ones. It is more expedient and more economical to cut thick sheets of metal with oxygen rather than with a plasma torch, despite the rather high cutting speed.

Plasma arc cutting is characterized by high speed and controlled flame heating. Figure cutting is performed by a plasma jet, and not by a hard cutting object, which gives cuts without jagged edges. For some types of alloys, strong heating causes destruction of the metal structure. This is unacceptable for shape cutting. Due to the fact that when processing with a plasma cutter, a very thin section is heated and cooling occurs quickly, the structure of the metal does not change.

Advantages of plasma cutting on CNC machines

Complex geometric and floral patterns in metal art, the patterns of which must be repeated with millimeter precision, can come out with slight differences from a hand cutter. The reason for this may be a wavering hand of the master, or an accidental holding of the flame in one place. The technology for applying each artistic element is added to the CNC machine program. The flame either goes out or lights up again, but only at the moment when the cutter moves to a given point.

[Show slideshow]

The peculiarity of artistic cutting of a painting with small elements is that the cutter moves from one edge of the product to the opposite. At first glance, this is illogical, but not for working with heated metal. If you save time on moving the cutter, then you will have to lose it in the seconds required for the natural cooling of the metal. In this case, the process of figure cutting will be longer.

If everything is clear with the technology of figure cutting on a programmable machine, then for a master working with a manual plasmatron, the cutting technique will have to be worked out using the trial method.

Main technical parameters of plasma cutting, advantages

Plasma cutting is carried out using a plasma torch. All process characteristics depend on the parameters of the gas or liquid stream

Main technical parameters that are worth paying attention to:

1. Speed. When cutting a metal sheet with a plasma jet, it is directed under high pressure onto the metal sheet. The principle of the whole process is to heat the metal to the point where it starts to melt, and then blow out the residue. The optimal speed for this is from 1.5 to 4 km per second.
2. Temperature indicators. To form plasma, the air must be heated to 5-30 thousand degrees. This temperature is obtained due to the formation of an electric arc. After reaching the required temperature parameters, the air flow is ionized and ultimately changes its properties, acquiring electrical conductivity.
3. There must be an electrical circuit. The work includes plasma torches with indirect and direct effects. When a direct impact device is used, it is necessary that the metal transmit electricity and be included in the general network, but for indirect impact devices, this parameter is not required.

Plasma cutting is popular because it has a number of obvious advantages:

• has much higher productivity compared to simple laser cutting;
• versatility – plasma cutting is suitable for a wide variety of metals;
• precision and high quality of cutting - “clean” edges without overheating and with a minimum cutting width;
• safety, since there are no explosive cylinders;
• low level of environmental pollution.

Relevance of using technology

The uniqueness of laser cutting lies in the ability to process products without mechanical impact on their base. Due to this, it is possible to form objects and decorative elements of incredible beauty from ordinary rough blanks. Moreover, they differ not only in their aesthetics, but also in their functional aspect.

That is why decorative laser cutting of metal is in increasing demand today not only in industry, but also in production. And the products obtained with its help are indispensable in everyday life and in a variety of sectors of human activity. Among the most frequently manufactured products, the following should be noted:

• Creation of decorative panels with perforation and different patterns;
• Pattern cutting of various metal structures for various purposes;
• Manufacturing of blanks and parts for their subsequent use in various industries;
• Creation of signs, all kinds of logos, inscriptions and other things;
• Production of housings for various equipment with their subsequent painting;
• Creation of elements for decorating or branding products;
• Cutting pipes, making inductor plates and much more.

Advantages and disadvantages of plasma cutting

As with other methods of cutting or cutting rolled metal, plasma cutting has both advantages and some disadvantages.

About the benefits

• Plasma cutting equipment is less expensive than laser equipment;
• The plasma torch easily copes with thick-walled rolled metal, which is inaccessible for laser cutting;
• Plasma can be used to cut any rolled metal, as well as conductive metals: steel, cast iron, copper, brass, titanium;
• The thickness of the cut made by plasma equipment depends on the type of device and tips. Devices that have a minimum cutting thickness significantly reduce the percentage of metal loss with an increase in concentrated plasma flow;
• the cut does not require additional processing;
• it is possible to perform complex shaped cutting;
• non-metallic materials can be cut with plasma;
• safety of plasma cutting equipment. This parameter is ensured by the absence of cylinders containing compressed gas. They are the cause of explosions or fires;
• with automatic cutting, especially with CNC machines, user intervention is minimal, which allows rational use of the labor of maintenance personnel.

With so many advantages, there are not so many disadvantages.

1. Twenty centimeter thick metal is not available for plasma cutting.
2. It is necessary to monitor the deflection angle, which should not exceed 50.
3. One machine – one cutter. It is impossible to cut with two cutters at the same time.

How to choose a plasma torch?

To cut metal with a plasma cutter yourself, it is important to buy equipment. Before making a purchase, it is recommended to take into account the properties and parameters of the device

They will have a great influence on the functions of the plasma torch. The price will also vary

Before making a purchase, it is recommended to take into account the properties and parameters of the device. They will have a great influence on the functions of the plasma torch. The price will also vary.

Plasma cutting can be done by two types of plasma cutting machines:

1. Inventory - has a compact size, its operation requires a small amount of energy, the device is lightweight with an attractive design. At the same time, it does not turn on for long; voltage drops will negatively affect the device;
2. Transformer - long switching time, if the voltage jumps, the plasma cutter does not fail. The size and weight of the unit are quite large; such a plasma cutter also consumes a lot of energy.

IMPORTANT TO KNOW: Gas (oxygen) metal cutting

When choosing a plasma torch for cutting with your own hands, it is recommended to pay attention to the parameters. Such a plasma cutter will be able to maximally satisfy the needs of the master and get the job done

Power

Depending on the characteristics of the product that needs to be cut, the power is selected. The size of the nozzle and the type of gas will also differ.

So, with a power of 60-90A, a plasma cutter can cope with metal 30 mm thick.

If you need to cut a large thickness, it is recommended to buy a plasma cutter with a power of 90-170A.

When choosing a unit, consider the current strength and voltage that it can withstand.

Time, material cutting speed

This indicator is measured in cm, which the machine can cut in 1 minute. Some plasma cutters can cut metal in 1 minute, while others can cut it in 5.

In this case, the thickness of the material will be the same.

If it is important to reduce cutting time, then it is worth considering the cutting speed. The devices differ in operating time - the duration of cutting metal without overheating

If it is indicated that the operating time is 70 percent, this means that the plasma cutter will operate for 7 minutes, after which it must cool down for 3 minutes.

If it is necessary to make long cuts, it is recommended to choose units with a long operating time.

Plasma cutter torch

It is worth assessing the material that will have to be cut. The plasma cutting torch must have the power to cut it efficiently.

It is worth considering that working conditions can be difficult and cutting can be intense.

Additional elements can be attached to the handles of such plasma cutters to support the nozzle tip at a certain distance. This makes the work much easier.

If a plasma cutter will be used to cut thin metal, then you can choose a unit whose burner receives air.

If you plan to plasma cut thick metal, you should prefer a plasma torch, the torch of which will be supplied with nitrogen.

External characteristics

When doing plasma cutting with your own hands, you most often choose portable plasma cutters, which are compact in size.

They are not difficult to operate without sufficient experience; shape cutting is available.

Stationary units are heavy and are designed for cutting thicker materials; their price will be correspondingly higher.

Advantages of laser cutting

If we talk about its main advantages, then first of all you need to pay attention to the following:

• Improving the productivity of the technological process by increasing the speed of material processing;
• The ability to use laser cutting of metal not only for individual, but also for mass production of products;
• Computer cutting control with the ability to form workpieces that most accurately match the design and drawing documentation;
• Non-contact processing with the possibility of eliminating the formation of static voltage on the surface of products;
• Minimal deformation of the workpiece due to the compact zone of thermal interaction of the laser beam with the processed base;
• Possibility of cutting of varying complexity with the formation of contours of arbitrary configuration.

What metals can be cut?

Using plasma technology, almost any metal can be processed:

1. Cutting and cutting of sheet metal from steel, titanium, non-ferrous metals (copper, aluminum, etc.) and their alloys (including bronze, brass, etc.).
2. Cutting steel of different thicknesses and workpiece shapes. Processing of carbon and alloy steels of almost all grades is provided, incl. high alloy stainless steels. Plasmatrons can be used to cut strips (narrow long steel strips) and cut rolled steel.
3. Cutting cast iron. Plasma ensures deep cutting, which makes the method more effective compared to other technologies.
4. Cutting and processing of pipes of different diameters. Special pipe cutters with centralizers are used. In addition to cutting, you can process the surface of pipes, chamfer, clean welds, and process edges.
5. Formation and processing of holes.
6. Shaped cutting of metal blanks. Special equipment even allows for artistic carving and production of parts of complex shapes.

Types of cutting tinplate

Sheet metal cutting can be done in two main ways: manual and automatic. The manual method is aimed at cutting strips, blanks along the contour, grooves using scissors or hacksaws. This process is very labor-intensive and takes a lot of physical effort. When cutting, you should follow safety precautions to avoid getting splinters in your eyes.

Cutting on automatic lines is a priority and more in demand. The equipment consists of several devices:

• Serving;
• Unwinding;
• Cutting block;
• Control panel.

All operations are carried out automatically without the involvement of workers, which is very convenient. Only one operator controls. After cutting, finished blanks are stacked in packs of up to 2 tons and sent to wholesale and retail customers.
