Cutting metal at home is a rather tedious process. And its quality often leaves much to be desired, forcing additional processing of the resulting faces. To correct the situation in many ways allows the use of special devices, including those made by hand. We will talk about one of these devices, namely the roller knife, today.

Roller knives for metal

The roller knife is gaining more and more demand and popularity today. This is due not only to the high productivity of such a device, but also to its rather simple device. The principle of operation of the mechanism is simple - two cutting disk-rollers rotate in different sides, pressing into the surface of the metal and thus cutting it. The friction between the metal and the knives ensures that the workpiece moves smoothly along the tool.

In the vast majority of cases, roller blades for cutting sheet metal include two rotating rollers - upper and lower. Depending on the variation of the cutting element used, such tools can be classified as follows:

• Parallel position knives - used to cut metal into strips, while providing a very acceptable quality;
• Edges with one inclined - this group allows not only longitudinal cutting of the material, but also cutting out ring and round blanks;
• Knives with several inclined - such devices make it possible to effectively cut workpieces of a round, curved or annular formation with a small radius.

It is worth noting that all of the above variations do an excellent job with cutting sheet steel, while the cut edges do not require additional attention and subsequent processing.

Homemade roller knives

With all its undoubted advantages, even the most simple model roller knife has a very decent cost. This is the reason for the inappropriateness of its acquisition for one-time work or periodic use. However, the optimal solution from a financial point of view still exists - it is quite possible to make a roller knife with your own hands at home.

The design of such a device can be very different. The most common variations are presented below (photo, photo 2). But in any case, the main part remains unchanged - the cutting knife. It should be made from the most durable and reliable steel alloy, the strength indicators of which must necessarily exceed those of the material being cut. If this condition is not met, the cut quality will be low, which will require additional processing of the cut edges.

Practice shows that the working life of factory-made knives is about 25 km of sheet steel, provided that its thickness is 0.5 mm. With a greater thickness, the resource will be correspondingly lower. However, the tool can be sharpened without problems and continue its effective functioning.

Speaking of resources homemade knives, then it is directly dependent on the material from which the cutting parts of the unit are made.

What can a knife be made of?

The options can be very different, here you need to pay attention to what exactly is planned to be cut. So, if it is not the most durable sheet steel in its structure, including aluminum, galvanized metal and other similar materials, the most common bearings will be a suitable solution. True, for this you will have to carry out a preliminary sharpening of their ends.

For cutting, one of the rollers, the one that will play the role of a drive one, is installed on the handle, due to which the knife will be pressed to the metal. Please note that the larger the diameter of the bearings, the faster the material can be cut.

In order for the cutting process to take place with maximum comfort and accuracy, the device can be additionally equipped with guides - this will not be particularly difficult, but in the future it is guaranteed to do good service.

The resulting tool is quite versatile and can be used in combination with a variety of metalworking equipment, including bending machines, which you can also make yourself at home.

Cutting sheet material into parts is carried out using various tools. Roller shears for cutting sheet metal are popular, the trend is due to the simplicity of design and high performance. The device is applied in the conditions of the industry and a small workshop.

Specifications of scissors

The intended purpose of roller knives is to cut steel sheets up to 1 mm thick. They are necessary at the site for the production of ventilation ducts, when working with roofing metal, when building a fence and arranging a roof.

The mechanism is used to obtain semi-finished products for the subsequent bending of profiles for various purposes. The equipment is installed in car body repair shops. In auxiliary productions, blanks are prepared for the assembly of racks and cabinets.

Shears with rollers will successfully replace the manual version or the guillotine due to a number of advantages:

• Compact dimensions and light weight.
• Simple device.
• Convenient to use.
• Just set up.
• Suitable for sheets different material: aluminum, tin, steel, roofing iron.

The finished product is obtained with a clean cut without burrs and bends. It is easy to cut sheet metal with such a device.

Scissors can be purchased at a specialized store or made independently. It all depends on the volumes performed and the economic component. With a daily cutting rate of 30–50 meters or more, an industrial design will be required.

Description of scissors

The task of dividing a sheet of metal into parts is solved by destroying strength bonds in a local segment.

The power part consists of two cutting rollers-discs with multidirectional rotation. Their cutting edges lie in the same plane. During rotation, the rollers are pressed into the surface and cutting occurs due to shear deformation. The sheet blank is fed to the tool by means of the friction of the knives against the metal.

The design of the cutting mechanism includes two rotating rollers located one above the other. Depending on the design of the cutting part, roller knives are distinguished:

• With one slanted edge for straight longitudinal cutting and cutting of round and ring workpieces.
• With parallel position of knives, cutting the material in strips with high quality. Most common.
• With multiple beveled edges for easy cutting of curved, round and ring-shaped workpieces with small radii.

All types of scissors provide cutting of sheet material with high quality, without the need for subsequent cleaning of the cut edge.

To increase productivity and obtain a smooth cut, the body with roller knives is installed on a stationary machine.

The cutting equipment includes a bed with supporting surfaces, equipment for fixing the material and a roller knife. The latter contains a body made of steel assortment, an overhead handle, cutting rollers, a mechanism for adjusting gaps in several planes.

The material for the cutting discs is tool steel.

The manufacturer lays down a work life of an average of 25 km in order to cut sheet metal with a thickness of 0.5 mm. With an increase in thickness, the service life decreases proportionally. The cutting element is subject to regrinding, which significantly increases the term of active operation.

How to make a roller knife

A purchased model of roller shears, even of the simplest design, is unprofitable for purchase in a small workshop or private household. You have to use it infrequently, and the device is expensive. The best solution is to make scissors with your own hands.

The design of the mechanism may be different, but the basis will always be a cutting knife in the form of a roller. The selected material for the manufacture of knives determines the performance of the device and the quality of the cut. Knives must be strong and reliable, with a surface hardness that significantly exceeds the hardness of the material being cut. Otherwise, a high-quality cut will not work, the edges will have to be further processed.

Homemade roller knives are made from bearings. To do this, the ends are sharpened to form a cutting edge. The drive roller is mounted on the handle. When working with it, they press the knife into the workpiece. The lower roller is installed permanently. In the process of cutting, you need to press the handle with the roller with one hand, and pull the sheet of metal with the other.

Selecting a larger bearing diameter will increase cutting speed.

For convenience and accurate cutting, guides are additionally installed.

Adjustment is carried out using oval holes, a set of gaskets and special bolts.

If you master the techniques of metalworking, the manufacture of a cutting device takes 7-10 days, along with the setting.

Every industry or individual involved in metalworking needs a metal cutting machine that meets cost, performance and safety requirements. Today, a large number of different metal processing methods are distinguished - metal processing with plasma, laser and pressure, as well as manual metal cutting with scissors. If you have not yet decided on the optimal method and suitable equipment for metal cutting, our article will help you do this.

Types of metal cutting

The process of metal cutting is the separation of blanks from cast, sectional or sheet metal. The most common and effective from an economic point of view today are such methods as plasma, laser and gas cutting. Very often, metal is cut with press scissors, which are capable of punching grooves and holes. different forms in steel of various strengths.

When choosing one of the metal processing methods listed above, it is recommended to focus on the quality of the work process itself, the amount of final waste and the accuracy of execution. An important point there is also the possibility of creating a small batch of parts in the most compressed lines at the best cutting price in specialized industries.

Moreover, the choice of one of them is justified taking into account certain criteria, such as work efficiency, end result, product cost. At the same time, there is a certain list of metals and alloys with which it is advisable to work with one or another equipment.

Gas cutting of metal

Gas cutting is a process of cutting metal products, which is based on the property of metals that are heated to a certain temperature (1200-1300 degrees) to burn in pure oxygen. Thanks to gas cutting of sheet metal in our time, it is possible to carry out a wide variety of types of processing - preparation of edges for the welding process, straight cutting of metal, cutting at an angle.

Essence of technology

It is customary to start cutting from the edge of the sheet. The surface to be cut must be free of rust, scale and dirt. Oxygen and gas are supplied to the burners from cylinders, where they are kept in a compressed state. The mass of one cylinder is 70 kg. The working pressure of oxygen per square meter is 300 kN, and that of gas reaches 50 kN.

In this case, the pressure can be adjusted in the reducer of the device, which is screwed onto the fitting of the oxygen cylinder. The reducer is equipped with a manometer high pressure, which shows the pressure of oxygen in the cylinder, and is also equipped with a pressure gauge low pressure, which provides information about the working pressure.

A sheet of metal is burned through and cut with a jet of oxygen, which is supplied under high pressure. The resulting iron oxides flow out in a molten state and are blown out of the cut cavity. The technology of metal gas cutting involves the use of a cutter, which is a kind of welding torch with a special device for supplying oxygen.

Types of gas cutting

In this type of welding, hydrogen (coke, oil and natural) and acetylene, kerosene and gasoline vapors are traditionally used, which can reach temperatures of 3200 degrees during combustion. Depending on the combustible gas used, hydrogen-oxygen, acetylene-oxygen and gasoline-oxygen cutting, as well as machine and manual cutting, are distinguished.

A separate type of gas cutting is flux-oxygen cutting, which allows you to separate metals that are difficult to cut - chromium-nickel and high-chromium steels, aluminum alloys and cast irons. In this case, the procedure is facilitated by powdered fluxes, which are blown together with oxygen.

In addition to separation oxygen cutting, when the cutting jet is almost perpendicular to the metal surface, oxygen treatment is used, during which the cutting jet is directed to the metal surface at an acute angle.

In this way, sheets of carbon medium and low alloy steels are cut, which have a thickness of 1 to 200-300 millimeters. In the video about gas cutting of metal, you will see that gas cutting of steel thicker than 2 meters is considered possible. Oxyfuel cutting is widely used in color and ferrous metallurgy as well as in private construction.

Requirements

To complete this process, a number of requirements must be met. Remember that the metal must have a higher melting point than the combustion temperature in oxygen. On the contrary, metal oxides should have a melting point lower than the melting point of the selected metal.

Make sure that the level of thermal exposure is sufficient to ensure the continuity of the cutting process. The metal to be treated must not have too high a thermal conductivity, as otherwise the heat energy will be rapidly dissipated. According to these criteria, which apply to gas cutting, low-carbon and low-alloy steels and iron are ideally suited for this procedure.

Advantages of gas cutting

The main advantage of gas cutting of metal is the ability to cut sheets of metal that have a large thickness - up to 200 millimeters. In this case, the width of the cut is 2-2.5 millimeters. With the help of equipment for gas cutting of metal, it is possible to draw a vertical cut edge, which will not be hardened during the process.

It is impossible not to mention the economic efficiency of this technology - gas cutting does not require large financial investments. The minimum requirements associated with maintenance process. The undoubted advantage of gas metal welding is the fact that it does not require any mechanical processing.

Plasma cutting of metal

Cutting metals using a plasma jet instead of a cutter is called plasma cutting. The plasma flow is formed as a result of blowing a compressed electric arc gas, which heats up and ionizes in the process - it breaks up into positively and negatively charged particles. The plasma stream usually has a temperature close to 15,000 degrees Celsius.

Plasma cutting methods

Allocate surface and separating plasma cutting. However, in practice, it is the separating technology of metal cutting that has received wide use. The cutting process itself is carried out by two methods - a plasma arc and a jet.

When cutting metal with a plasma arc, it is included in electrical circuit. The arc mentioned above occurs between the workpiece and the tungsten cutter electrode. If you chose the second method, then remember that in the torch, the arc is formed between two electrodes. The sheet to be cut is not included in the electrical circuit.

Plasma cutting is superior in performance to oxygen cutting. But if you need to cut titanium or thick metal, then it is recommended to give preference to oxygen cutting. When cutting non-ferrous metal, plasma cutting is considered indispensable. This is especially true for aluminum.

Plasma cutting machines

For the formation of plasma, it is customary to use active and inactive gases. The first group includes air and oxygen, which are used when cutting ferrous metals (copper, steel and aluminum), and inactive - hydrogen, argon and nitrogen for cutting alloys and non-ferrous metals (high-alloy steel, which has a thickness of up to 50 millimeters, brass, copper , aluminum and titanium).

To mechanize the procedure, metal cutting machines were developed - semi-automatic and portable machines of various modifications. Semi-automatic machines work with inactive and active gases, while portable machines use compressed air exclusively.

Cutting metal with plasma at home is carried out using hand-held devices, which include a cutting plasma torch, a collector, a cable-hose package and a lighter designed to excite the cutting arc. Such kits allow you to perform a limited amount of work with equipment loading no more than 50%. Therefore, it is recommended to equip them with welding converters and rectifiers for the time of operation.

Essence of technology

The beginning of the metal cutting procedure is the moment when the plasma arc is initiated. Having started cutting, it is necessary to maintain a constant distance between the metal surface and the plasma torch nozzle, which is 3 - 15 millimeters.

Strive to ensure that the current is minimal during operation, because with an increase in current strength and an increase in air flow, the service life of the electrode and plasma torch nozzle decreases. But the current level must ensure high cutting performance. The most difficult operation is punching holes, since a double arc may form and the plasma torch may fail.

Remember that the tool for cutting metal during punching should rise above the surface of the part by 20 - 25 millimeters. The plasma torch is lowered into the working position after the sheet is pierced through. If you are punching holes in sheets that are thick, it is recommended to use protective screens that have holes with a diameter of 10-20 millimeters. Screens must be placed between the plasma torch and the product.

When cutting aluminum using an argon-hydrogen mixture to increase the stability of the arc, the hydrogen content should not exceed 20%. It is customary to cut copper using hydrogen-containing mixtures. Brass needs a nitric mixture or nitrogen. After cutting, copper must be cleaned to a depth of 1-1.5 millimeters without fail. But this requirement is not at all necessary for brass.

Laser cutting of metal

Laser cutting is a fundamentally new type of metal processing, which is characterized by extremely high precision and productivity. Such cutting machines have revolutionized the world of metalworking, making the process of creating complex metal structures easier, faster and more affordable. Laser cutting in our time is confidently replacing other types of processing of metal blanks and is becoming more and more popular.

Essence of technology

Do-it-yourself metal laser cutting technology today is one of the most advanced technologies in creating various parts from sheet materials. The procedure is good for its versatility, because it allows you to work with any materials - metallic and non-metallic origin.

The laser beam is a narrow beam of light of small diameter, which has a high intensity. If the laser beam is aimed at metal surface or other hard object, the product will reach a high temperature. It is enough for the metal to begin to melt at the point of contact. But at the same time, the surface areas that are adjacent to the beam remain hot, but are not damaged.

By moving the beam over the surface, it is possible to create a very thin high-quality metal cutting line with ideally thin edges, despite the thickness of the metal being processed. The area of ​​the laser beam that hit the plane is literally measured in square microns. But at the same time, during laser cutting, the energy density that is directed to the metal is excessively high, which causes the heating region to appear.

As a result, a metal melt occurs locally, which is accompanied by the removal of substance molecules. Devices for laser cutting are ordinary coordinate tables that are mated with a head, which is controlled by the microprocessor of the machine and which moves according to a given program over the surface of the sheet being processed.

Laser cutting machines for special purposes can be produced, for example, laser cutting machines for pipes have been popular recently, which are suitable for any profiles. In this case, you can carry out processing immediately along the entire length of the part. This is enough effective method, which provides tight control of the cutting geometry when using a laser machine.

Advantages of laser technology

The undoubted advantages of laser technology include:

• complete absence of physical deformations and marriage during the operation of the machine;
• the possibility of functioning of the machine with ductile metals;
• the absence of microcracks on the surface of the finished product;
• precision processing accuracy of the laser machine;
• high speed of work;
• small cutting thickness;
• wastelessness of the machine;
• high level of automation of the laser cutting process;
• acceptable cost of cutting metal.

Use of laser cutting

Work on a laser machine occurs by burning sheet material through a laser beam. Due to the absence of direct contact between the part and the cutting head, the equipment allows processing safely fragile products, successfully copes with carbide material, and easily provides high-speed cutting of thin sheet steel.

The technology is also considered beneficial in situations where products are produced in small batches, because the costs of manufacturing expensive molds for casting are excluded. The equipment is able to cope with steel of any condition and quality, it works well with aluminum, aluminum alloys, copper, brass.

A very significant nuance of such a technological process is simplicity in relation to working with flat and three-dimensional parts, as well as complex contours.

Laser cutting is one of the technologies in which the cost of the product when creating complex products almost does not depend on the size of the batch that is processed by the machine. That is why laser cutting technologies are widely used in private construction and households, while the time to obtain the final result is minimal.

Guillotine cutting of metal

For high-quality and fast cutting of metal, special sheet shears - guillotines are used. The name of such metal-cutting machines comes from the similarity of the work of scissors with a medieval execution tool. But today guillotine shears are used for harmless purposes.

Choice of sheet shears

The main criteria for choosing a guillotine is the type of production: piece or serial, the thickness of the metal sheet, the length of the metal slitting line and mechanical strength. Consumers, depending on their goals, can choose simple manual or electromechanical guillotines. Many models of sheet shears are additionally equipped with industrial electronics and options that increase the productivity of metal cutting.

Despite the abundance of drive types, all models of guillotines have the same principle of operation. To begin with, the sheet to be cut is placed on the desktop along the set stops between the lower and upper knives. First, it is worth pressing a sheet of metal against the guillotine table with a pressure beam. Then the upper knife moves and the metal is cut. The finished parts can then be transported from the metal cutting area.

The accuracy of cutting metal sheets by means of guillotine shears is ensured by the sheet pressing mechanism. Cutting, as a rule, is carried out according to the markup or stop: it is customary to install accurate rear rulers on guillotines, which allow achieving high accuracy of the cutting procedure. Some models are equipped with a return tray for collecting cut metal.

When choosing a certain model of scissors, you need to carefully consider the list of required functions, because the advantages of work do not always consist in a large number of them, while the price of such a machine depends directly on this indicator. For work at home, a guillotine with a set of only the necessary functions is quite suitable; multifunctional scissors are required in large industries.

Types of guillotines

According to the principle of the device, sheet shears can be manual, pneumatic, hydraulic, mechanical, automatic, and also combine several combinations at the same time. Manual and pneumatic guillotines are among the simplest and are used for straight cutting of metal sheets.

Electromechanically driven hydraulic shears are easy to operate and high level labor, which can be noted in the video about cutting metal. Cutting accuracy is ensured by adjusting the position of the knives. Hydraulic guillotine shears with automatic or manual adjustment of the gap that forms between the knives are very popular.

Use of guillotine shears

Guillotines are designed for cutting in the transverse and longitudinal directions of metal sheets that have different thicknesses. Some types of sheet shears are capable of cutting round, square or angled metal. The main characteristics of guillotines that are used for cutting metal are the length and maximum thickness of the cut.

The use of guillotines allows you to get an accurate cut of the material without notches and dents, while the equipment does not damage the polymer coating and metal color. Depending on the technical capabilities, guillotine shears are used in mass and individual production.

After reading our article, you got acquainted with the main types of sheet metal cutting. Recalling once again - guillotine, laser, plasma and gas cutting. Each of them has its own advantages and disadvantages. Remember that each type of metal cutting is associated with the use of special equipment and tools, which requires the consumer to have certain skills and the strictest safety precautions.

Sheet metal cutting can be characterized as a technological process, as a result of which a metal product is divided into parts, acquiring specified shapes and sizes.

The article describes sheet metal processing, talks about metal cutting methods, describes roller shears, automatic lines, etc., and also considers special equipment for sheet metal processing (machine, cutter, etc.).

Cutting methods are divided into two main groups: mechanical and thermal.

Before choosing a specific type of cutting, you need to know the advantages of each type, the essence of the process, and also in what cases a particular type of cutting is used.

The basis of mechanical cutting is a cutting tool that has characteristics of strength and hardness higher than that of the metal being processed.

Another such method of processing is called cold. Machining includes guillotine, band saw and waterjet cutting and grinder cutting.

Cutting with scissors and grinder

For cutting metal in this way, special guillotine shears are used, which can be used for thin-sheet metals (profiled sheet, galvanization).

The cutting element is a knife. Guillotine shears are mechanical, automatic, pneumatic, hydraulic.

Manual and pneumatic guillotine shears have the lowest prices of all types of equipment designed for straight metal cutting.

However, an inexpensive tool has low productivity, so you have to put in a lot of effort.

Therefore, most often preference is given to special power tools or industrial equipment, which work much easier and faster.

An electric tool is a grinder (angle grinder).

This is due to the fact that abrasive wheels reduce the protective characteristics of the metal. When cutting with a grinder with your own hands, you must follow safety precautions: your eyes and hands must be closed.

The main danger when working with a grinder is the flight of fragments.

Effective cutting with a grinder is made by the heel of the disk - the near lower part of the circle. Every 5 minutes, the tool must be turned off to avoid overheating.

If the grinder cuts long pipes, then you need to start from the hanging edge. Thick parts are cut straight with a grinder.

Guillotine shears work according to the following principle: the cutting sheet is placed on the table between the knives.

The metal must be pressed against the table with a beam, and then the upper knife must be moved.

Guillotine shears provide precise cutting of metal, which is explained by the clamping mechanism. Guillotine shears are designed for longitudinal and transverse cutting of sheet metal. This slitting attachment is the most popular.

A different kind of tool is applicable for square, round and corner metal, due to the fact that the knife is located at any angle. The main characteristics of the device are the length and thickness of the cut.

Guillotine shears provide an even cut without roughness, the knife does not spoil the paint and polymer coating and the characteristics of the workpiece.

There are also circular shears for longitudinal cutting, which is carried out by rotating round knives.

The lower and upper circular knives rotate in different directions at the same speed. The movement of the workpiece is provided by friction against the knife.

Predominantly, sheet metal cutting shears are used for roofing works for longitudinal processing.

Circular shears work like this: the sheet to be processed is placed on the machine, inserted between the support and pressure rails.

Then the sheet is fixed with clamps and the circular shears are moved along the cutting line. When the circular shear begins to rotate, the knife cuts the product.

Circular shears are easy to use when cutting metal with your own hands (especially if the cutting lines are pre-marked). The knife produces precise and high-quality cutting.

This tool is designed for longitudinal cutting only. Quite popular are automatic lines.

Automatic lines consist of a feeder, an unwinder, a material feeder, a cutting unit and a control panel.

Automatic slitting lines have the main advantage that there is no need to involve people, since all operations on the line are carried out under the control of one person.

Roll shears are often used. The roller knife is used for straight and curly cutting. The roller cutter is suitable for cutting round and oval, square shapes.

Band saw cutting

Roller shears are not suitable for such cutting, but a machine with a tape cutter is used, which has teeth, the distance between which is selected based on the quality of the material being processed.

Cutting has excellent characteristics: high productivity, good workmanship, thin cut, not exceeding 2 mm.

Such a machine is capable of processing any alloys. One of the advantages is the ability to cut at any angle.

The machine also has disadvantages: the inability to perform curly cutting.

Waterjet cutting is used for materials of different hardness: concrete, stone, different types metal, etc. basis this method is the use of a mixture of abrasive materials and water.

The machine feeds the mixture with a high pressure pump, reaching the highest speed, which ensures cutting.

This method is one of the most promising, it allows cutting thin metals without abrasive materials, only with water.

Thermal types

Thermal cutting of sheet metal is based on thermal action, after which the cut point melts and burns. The main methods are gas, plasma and laser cutting.

gas cutting

Cutting and bending with the use of oxygen and combustible gases has affordable prices. The method is not applicable to all materials. Can be performed and curly cutting.

The condition for high-quality cutting is the combustion temperature of the metal, which exceeds the melting point.

The technology principle is as follows: the surface is heated up to 3000°, which depends on the metal being processed.

This temperature is achieved using a mixture of combustible gas and oxygen.

For a quality cut, the amount of gas supply and the speed of the torch must be correctly adjusted.

Basically, this method is used for installation work, in the production of metal structures.

The method is not without drawbacks, which include a large width of the seams and subsequent processing.

Also, with uneven heating of the surface, deformation and deterioration of the quality of the metal occur.

The advantage is the ability to process products up to 20 cm thick, with a cut of 2.5 mm.

Plasma cutting

Plasma sheet metal cutting is a modern method that uses a plasma jet instead of a cutter.

The basis of the method is the use of gaseous substances in a high-temperature plasma state, obtained under the influence of an electric arc discharge.

Cutting can be done in two ways: jet and arc. When arcing, the sheet is included in the circuit, the arc is formed between the metal and the electrode. In jet cutting, a cut is formed between two electrodes.

Homemade devices can act as a plasma cutter

The plasma flow occurs on the plasma torch, which has an electrode that forms an electric arc.

Plasma cutting is used for cutting and bending various metals up to 20 cm thick.

Due to the high temperature, there is no thermal effect on the areas near the cut, which prevents deformation of the sheet, and also does not impair the characteristics of the metal.

This is especially important when working with stainless steel. Curly cutting can also be performed.

Do-it-yourself plasma cutting and bending are performed by hand-held devices, in which the start of cutting is the moment the plasma arc appears.

During the process, a distance of up to 15 mm must be maintained between the plasma torch nozzle and the metal.

laser cutting

The laser machine for cutting and bending metal is the latest equipment. Sheet metal laser cutting is based on the thermal energy of a narrowly focused laser beam.

The main advantages of the technology can be called accuracy, cleanliness of processing, thin cut.

The method is used for jewelry and other products that require complex curly cutting and bending. It is advisable to use the method for metal with a thickness of not more than 15 mm.

Prices for equipment are not the lowest due to the novelty of technology.

The essence of the method is as follows: a high-intensity laser beam is directed at the metal, heating the product.

After that, the surface begins to melt at the point of contact, and the adjacent areas also heat up, but do not deform and do not lose their characteristics. Moving, the beam creates a thin cut line with smooth edges.

The tool for laser cutting is represented by coordinate tables mating with a head controlled by microprocessors.

Laser machines perfectly process fragile products, carbide materials.

Sheet metal processing is carried out different ways(roller knife, machines, cutters, etc.), from which you can choose suitable option cutting and bending by hand. And for bending, homemade fixtures can be used.

The canning industry is gaining momentum, supplying the market with countless amounts of agricultural conservation. Reliable safety of food products is provided by tinplate. Obtaining quality raw materials to promote a business is essential. Tin plate cutting ensures the production of various packages, containers, containers, containers, etc. The company "Tinplate-Service" is ready to offer the best services.

Types of cutting of white food tin

Sheet metal cutting can be done in two main ways: manual and automatic. manual method is aimed at cutting strips, blanks along the contour, grooves with scissors or hacksaws.
