For cutting and engraving metal on modernEnterprises often use special types of machines - laser. This type of equipment in comparison with the traditional has a number of undeniable advantages. Such machines are used mainly for processing small batches of blanks. In this case, cutting and engraving can be done on products made from a variety of materials: plastic, plexiglas, fabric, etc. But most often, equipment of this type is used to process wood and metal blanks.
Of particular complexity is the construction of suchThe equipment, like a laser machine for cutting and engraving, is no different. The principle of its operation is relatively simple. Pre-manually developed drawing cutting or engraving blanks. Next, the product is fixed on the table of the machine. Cutting or engraving are made using a special laser head. There is no mechanical contact between the cutting tool and the product. Cutting is performed by a beam heated to a very high temperature. In the place of the cut, the metal simply melts. It is removed with a stream of gas.
On modern machines of this type, different in design working tools can be used. Laser cutting is done with heads:
Solid state.They are made on the basis of yttrium aluminum garnet. Heating is performed using high-voltage discharge lamps. The generation mode in this case can be both pulsed and constant.
With diode pumping.This is a relatively new kind of lasers. The discharge lamps in them are replaced with high-power LEDs. Such lasers are quite expensive, but also more convenient to use and safe. The fact is that in this equipment the elements under high voltage are completely absent.
CO2 lasers.This type of equipment today is considered the most perfect. With its use it is possible to cut not only steel and wood, but also, for example, aluminum, which is distinguished by its high light reflecting ability.
This element in modern laser equipment usually has an end-to-end design. Such tables are convenient because on machines, supplemented by them, it is possible to process blanks of absolutely any length.
If desired, a modern laser cutting machineand engravings can be supplemented with all sorts of elements that significantly enhance its functionality. For example, such nodes as a lifting table, allowing to increase the height along the Z axis, turning devices designed for engraving cylindrical parts, honeycomb surfaces for processing workpieces of very small sizes, etc. are very popular.
Like any other production equipment,such machines can be automated using a numerical control system. The rather high cost is what usually distinguishes such a laser machine. CNC, however, makes this type of equipment much more productive and convenient to use. It is simply impossible to make any mistakes in the engraving and cutting on such a machine. After all, they are managed by means of a special, developed specifically for this particular type of software procurement. The only case where problems may arise with the use of such a machine is errors in the development of drawings.
Удобство использования оборудования этого типа lies in the fact that any manual work on it is not necessary. The operator of the laser machine only monitors the quality of the blanks coming out from under the cutter and the uninterrupted operation of its work. Typically, such equipment is complemented by a remote control.
The advantages of such equipment as a laser machine for cutting and engraving, there are many. These include primarily the fact that:
Due to the absence of mechanical contact, the possibility of crushing the workpiece or the appearance of any scratches on it is excluded.
Cutting and engraving on such equipment can be done with the highest degree of accuracy.
The cut when cutting blanks is very clean. Therefore, the ends of the resulting products do not require additional processing.
Гравировка или раскрой деталей на таких станках may have absolutely any degree of complexity. Even very small elements of patterns and inscriptions on such machines come out neat and look great.
In addition, the use of modernlaser machine allows good savings on material. After all, waste in the processing of workpieces on such machines almost never happens. Also, laser machines are valued for their small size and low weight. It is possible to install such equipment in the workshop without using a foundation.
Most often equipment such as a machinelaser cutting of metal or any other materials, use all sorts of companies engaged in the manufacture of promotional products. With such equipment it is very convenient to make all kinds of stamps, seals, souvenirs, posters of complex design, etc. In addition, laser patterns make patterns for the textile industry and beautiful interior elements of different materials. The equipment of this variety is also used in the areas of:
construction;
aircraft manufacturing;
light industry;
machine building;
shipbuilding.
Parameters of laser machines depending on the scopeuses and designs may be different. Below for an example we present to your attention a table with the characteristics of the model RJ 1390, designed to work with wooden blanks. It is very user-friendly and efficient laser machine. CNC is also provided for.

As you can see, this is actually a good laser machine for wood. When using it, you can make products of almost any complexity, and quite quickly.
For engraving and cutting blanks from thisThe material is commonly used modern powerful model with CO2 tool. The laser metal cutting machine can be used for working with ordinary steel, stainless steel, aluminum, brass, copper, etc. The power of the laser beam in such units is very large. On the modern market there is equipment of this type designed for cutting sheets up to two centimeters thick.
For each type of metal is developed its owntechnology cutting or engraving. So, the machines intended for cutting of a stainless steel are usually supplemented with the nodes which are responsible for processing of a detail with nitric acid. This substance protects the metal from oxidation and fire due to high temperature. For copper, since this metal is very hard, machines with very powerful tools are used. Laser cutting on such equipment is usually carried out at very low speeds. To work with copper, machines are used mainly with solid-state heads.
The easiest way to process on the laser equipment is steel and brass. In this case, no additional devices are required, and the setting is made elementary.
How much can a modern laser cost?machine? The price of equipment of this type depends on many factors. Small models are in the range of 90-100 thousand rubles. For a more powerful machine, equipped with all sorts of additional devices, you will have to pay from 200 to 500 thousand rubles.
Thus, a modern laser machine forcutting and engraving - reliable, productive and high-quality equipment. It is advisable to use it mainly in small and medium-sized workshops. Perhaps the cost of buying such a machine will be serious. However, this type of equipment will pay for itself due to high speed of work and saving on material very quickly.
