Drawings of braziers for plasma cutting. Methods for artistic metal cutting

artistic cutting metal (another common name is curly) is the creation or application of original drawings, inscriptions or other pictorial elements to sheets of material. It can be performed using special equipment, most often machine tools, which allow the processing of durable and hard material such as steel and other metals and alloys. To work on such equipment, as a rule, professional skills are not required, it is enough to carefully study the instructions and processing techniques.

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

• laser;
• plasma;
• hydroabrasive;
• guillotine.

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

laser cutting

When processing and cutting the material, a powerful laser is used. 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 directed impact, there is a rapid heating, melting, and then evaporation or blowing of the material in the area subjected to cutting. At the same time, the technology makes it possible to obtain a narrow cut with an extremely small zone of influence on the treated surface.

Laser cutting has a number of advantages:

• relatively low cost (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 technological processes(when using serviceable equipment);
• the absence or extremely small deformation of the material, which is achieved through narrowly focused processing;
• the ability to create a wide variety of complex contours;
• no need for subsequent finishing or surface treatment.

Thanks to the features of the technology, using laser cutting, you can make drawings of any complexity that do not require additional processing, since the edges and edges immediately turn out smooth and even.

The disadvantages of laser cutting include the inability to work with aluminum and its alloys with stainless steel. This is due to 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

It is carried out with a plasma jet, which is used as a cutting tool. It is created like this:

• 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 a short circuit;
• pressurized gas is supplied from the nozzle;
• under the action of an electric arc, it turns into a plasma jet, the temperature of which reaches 30 thousand degrees, and the speed is 1.5 thousand m / s.

With the help of figured plasma cutting, it is possible to process a sheet with a thickness of up to 10 cm, and with the use of some industrial machines - up to 20 cm.

Plasma cutting of metal has the following advantages:

• the ability to create drawings and figures of any complexity;
• high-quality, clean and smooth cut;
• the possibility of processing all types of metals;
• the 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 without compromising the quality of the workmanship. Compared to cutting with laser equipment, plasma has a greater productivity and a range of materials that can be processed.

To disadvantages this method cutting include:

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

Given the advantages and disadvantages of each of the described processing methods, practitioners are inclined to believe that plasma cutting is the most in demand, as it has the best price-quality ratio.

Art cutting equipment

For each technology used in processing, a significant number of different equipment has been developed.

laser cutting

Machine tools for laser metal processing are quite expensive. They are produced by many foreign companies, the most famous of which are: Trumpf (Germany), ESAB (Sweden), MultiCam (USA), Mazak (Japan), Bystronic (Switzerland), etc. Despite the fact that the technology has been used for two decades, only relatively large industrial enterprises can afford to purchase new equipment from listed companies.

However, it should be taken into account that the market is widely represented by the offer of equipment of this category, which was already in use, but is in working condition. Even in this form, it almost always surpasses numerous Chinese-made analogues, which, even new ones, do not differ in either processing quality or operational reliability.

Plasma cutting

There are two types of equipment for metal plasma processing:

• inventory plasma cutter. Compact, characterized by economical energy consumption, but more demanding on voltage stability;
• transformer plasma cutter. More reliable, but requiring significant energy consumption, has a large size.

When choosing equipment for plasma cutting of metal, the following criteria are taken into account:

• power;
• work performance;
• the material from which the burner is made;
• appearance and design of the unit.

Plasma cutting equipment is extremely widely represented on the modern market, so everyone can easily find a model that suits him.

Conclusion

The use of laser or plasma cutting of metal allows you to get a quality product at a relatively low cost, thanks to the use modern technologies and the latest advances in material processing.

It is interesting to learn the experience of people who used various technologies for artistic metal cutting in practice. It can be stated in the comments under the article.

Answering your questions, dear visitors of the site, we discussed a wide range of production problems of plasma metal processing. You can find out the details in the introductory part of the article. But, in addition to the production cutting of metals, there is an artistic cutting of metal with plasma. That's what we're talking about today

In a nutshell, this is a type of metal processing in which a plasma jet is used as a cutting tool. Gas is supplied to the plasma cutter nozzle, and an electric arc is ignited between its electrode and the metal being cut. It turns the gas into a plasma jet with a temperature of T = 5000...30000 °C and a speed of 500...1500 m/s, which can cut metal with a thickness of ≤ 200 mm (however, in practice, limiting thicknesses are economically more profitable to cut, after all, with oxygen). All the details can be found in the article and other articles of the site (we recommend that you look at the links).

Modern equipment allows high-quality and fast work on artistic plasma cutting in accordance with the sketches and drawings of the customer.

Application of products of artistic metal cutting with plasma

Now it has become fashionable to decorate in country houses premises, facades and adjacent area art products from metal, made by plasma cutting. Most often decorated:

• balconies;
• fences;
• railing;
• doors.

Garden sculpture made of metal and various decorative trifles that decorate the house, facade and plot are very popular. Metal products made by a good craftsman have a number of advantages over other decorative elements:

• it is original, elegant and beautiful;
• they are strong, durable, wear-resistant;
• compatible with most other materials.

These products are versatile and unique. If the balcony country house decorate with metal elements, then this will undoubtedly decorate the facade. And if the lattice, designed to prevent unauthorized intrusion, is made using artistic cutting, then, in addition to the main function, it will serve as a magnificent decoration.

The door is a kind of business card of the house and decorating it with metal elements will give it a certain charm and style. The decoration of the visors on the facades looks very impressive, gives the facade a feeling of some magical antiquity and looks just great. You can cut anything:

• mailbox;
• vane;
• gates, gazebo, tables and benches.

Separately, it should be said about garden sculptures. With their help, you can create a real fairy tale on the local area. The effect will be stronger if a multi-colored anti-corrosion coating is applied to them.

Today, a variety of elements of the interior of the house can be made of metal. This will bring additional harmony, coziness and comfort to the house. The situation changes dramatically if you install metal decorative items in the house - the usual interior details will look completely different.

But radical solutions should be avoided, because they can visually narrow the room and make it cold. Even if the interior is interesting, it is unlikely to satisfy you. There must be a measure in everything.

Equipment for artistic metal cutting with plasma

There are many machines on our site that will successfully cope with this task. Refer to the articles, and be sure to use the links in these articles.

Equipment equipment (CNC) gives many advantages:

• the possibility of performing a geometrically complex cut;
• high speed, despite the variety of shapes and ornate lines;
• only that part of the product on which cutting is performed is heated by plasma. This significantly increases the safety of the process;
• artistic plasma cutting of metal gives a clean cut, additional mechanical restoration which is not required;
• place heat treatment do not deform and no sagging is formed on it;
• good pattern repeatability, etc.

The operation of plasma art cutting on CNC equipment is simply an indispensable operation in the conditions of small-scale and piece production. On such equipment, you can even create paintings that will serve as a great decoration for the office and fit perfectly into the interior of any building.

Our company produces very beautiful, high-quality gates and wickets, the design of which is based on ornaments and compositions, including figures of people, animals and birds, images of trees and plants, mountains, clouds and lawns. How are these products made? In this article, we talk about the technology of air-plasma cutting, which allows us to make such things from metal that were previously made only by hand and for individual orders.

Automatic cutting

We create our products from sheet metal. The task is to accurately and accurately cut out the required pattern on the sheet. For processing, we use metalworking machines that allow you to quickly and accurately create almost any picture. The main working element of the machine is the cutter, which can automatically move over the processed sheet of metal. 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 (software) sets the cutting parameters and the 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 size of the coordinate table. The positioning accuracy of the torch and the cut parameters determine the quality of the finished product. When cutting, you can use different (according to the physical principles of the impact on the material) cutters. Hydroabrasive and laser technologies are widely used.
Waterjet cutters the metal is exposed to a thin, pressurized jet of water containing particles of an abrasive substance.

With such exposure, microparticles break out of the metal (or other material) and are washed off with water. Thus, a cut is formed. The rate of water supply abrasive material and the size of its particles determine the cutting parameters.

At 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 - 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 for metal processing air plasma cutting. Let's dwell on its features in a little more detail.

Air plasma cutting

The cutting tool in plasma cutting is a plasma arc. Plasma is a high-temperature state of matter. The arc temperature (up to tens of thousands of degrees) allows you to cut almost any material. High operating temperatures make it possible to use this technology for high-speed metal cutting.

Metal is cut by a working plasma jet. The arc must be torn away from the torch nozzle, otherwise the nozzle itself will melt and the torch will fail. Plasma is created by an electric arc in a gas stream supplied through a nozzle. Gas under pressure of several atmospheres passes through a thin nozzle of the nozzle. The narrow jet creates a very precise cut. An electric arc is created between the electrodes (torch nozzle and sheet metal). The temperature of the arc depends on the power of the electric discharge. At temperatures from 5000 to 30000 degrees Celsius, the gas passing through the nozzle at a speed of 500 to 1500 m/s turns into a plasma. In this way, the air-plasma cutter allows you to absolutely accurately and quickly create metal products. The quality with this technology is so high that additional processing of the cut is not required.

Products Metal-City

metal city produces a wide range of products made using air-plasma metal cutting technologies.

You can get acquainted with such goods in detail on the pages.

CNC is by far the most common way to create metal decorative elements and metal jewelry,

as well as the manufacture of signboards, stands using metal elements. Decorative metal elements are used to decorate gazebos, benches, gates, fences and other structures. Previously, they used the hot forging method for their manufacture. Today, products made on machine tools are becoming very popular.

Advantages of artistic laser cutting

Decorative has become widespread today. The main advantages of this method include:

• the ability to work with thin metal;
• a significant reduction in the time to manufacture the product;
• the possibility of obtaining openwork products with thin elements;
• the finished product does not require additional processing. All cuts are clear, without sags and notches.

curly on a CNC machine allows you to make decorative elements and souvenirs from sheet metal exactly the same. Manual cutting with a laser does not guarantee such a result, the master's hand may tremble, resulting in noticeable differences in individual rapports of the pattern.

Features of laser cutting

To obtain a clear contour in the cut out pattern, it is necessary to ensure constant speed incisor. If you hold it in one place for at least a fraction of a second, then this element will turn out to be not clear. That is why, to create complex compositions with a large number of small and closely spaced parts, you should use machines whose operation is controlled by automation. A feature of the work of a CNC machine that performs artistic metal cutting is that the work is carried out in several places at once. The cutter is constantly moving along the sheet of metal from one end to the other. This is due to the need to cool the metal during operation. Artistic technology essentially does not differ from the processes of industrial metal cutting and sheet metal cutting. The design project is converted into vector format and the file is loaded into the computer of the laser machine. Further processing is carried out automatically, under the control of the operator. In our production, we usecomplex model LK 6020With maximum power 3000 W., which allows you to process a sheet 6 meters long, up to 2 meters wide. Sheet thickness of carbon steel grades such as st. 3, 20, 09G2S and others can reach up to 20 mm, the thickness of the processed stainless steel sheet (12X18H10T, AISI 321, etc.) up to 12 mm.

Reviews on the quality of work carried out

We accept orders for the manufacture of various decorative elements metal, which can be used for various purposes. The quality of the products produced does not cause any complaints from our customers.

Cost of decorative laser cutting

Decorative elements made of metal, on which is carved openwork pattern are in great demand. The cost of a service such as cutting artistic metal depends on the complexity of manufacturing and the amount of work to be done. The final price can only be calculated after discussion individual features products and sketches. Also on cost finished products additional processing affects, if necessary, we will perform grinding or painting.
