What is laser cutting metal?
Laser cutting technology is based on the fact that the beam has a precise direction and is obtained through the operation of dedicated equipment. Since the contact of the laser beam with the surface is equal to a few microns in this case, the crystal lattice of the material reaches the temperature required to melt the metal.
The minimum contact of the beam with the surface ensures that the rest of the part will not actually heat up during operation. This can ensure the safety of personnel when using the equipment.
Another advantage is the cutting error, which meets the technical minimum requirements. At the cut, the metal melts and immediately evaporates and boils. At the same time, the distance from the laser cutting metal equipment to the part is less than one centimeter!
In work, metal parts of various thicknesses are allowed. For example, our equipment allows you to cut ferrous metals with a thickness of no more than 25 mm, stainless steel no more than 20 mm and aluminum no more than 12 mm! (More)
This work is very precise and efficient. The parts cut in this way may not undergo additional mechanical repair and will be immediately handed over to the next necessary process or use. This greatly saves the cost of the manufacturer.
Although the main purpose is to cut parts and workpieces, using laser equipment, you can mill and drill grooves of the required diameter and depth.
Laser cutting metal equipment is very suitable for engraving. In this case, do not use equipment that is difficult to use, and the diameter of the laser device should be the smallest.

The working principle of laser cutting equipment
These devices are simpler and more compact in design, but they have more power than other devices that perform metal processing by mechanical means.
The main element of the device is the rod, which is the heart of the transmitter. Therefore, the rod is excited and pumped by the continuous light flux.
A special system places the focus on the beam, and the resonator gives the beam the force needed to melt.
All units of the equipment are controlled by software using automation and software stored in the machine's memory.
The most productive gas used in this equipment is oxygen, because it can reach the highest temperature when used compared to other gases. This is due to the reaction that occurs when oxygen comes into contact with hot metal surfaces. The processing speed depends on the purity of the oxygen.
Advantages of using metal laser cutting:
Since there is no mechanical stress, any metal can be processed: from brittle to sufficiently strong materials.
The highest cutting accuracy and smooth workpiece edges. No defects in work.
The part can be used immediately without further processing.
Due to the accuracy of the work, parts of any shape can be cut.
To load the table into the device, a drawing drawn in any drawing program is sufficient.
Efficient is combined with a higher order of productivity.
The parts can be placed compactly on a piece of paper.
Overall it saves resource usage, finances and working time.
