In the manufacture of various structures from metal or in the production of blanks, laser cutting of metal is increasingly used. This is one of the economical and rather progressive methods of the so-called metal cutting. If we define the concept of laser cutting, then, first of all, it is cutting, cutting of a sheet according to a given drawing by means of a focused laser beam. Almost any metal alloy can be cut in this way.
The end result is a workpiece with smooth edges, a narrow cut and a small heat-affected zone, which reduces subsequent processing costs. High productivity is another indisputable plus of laser cutting. This is especially noticeable when cutting thin metal sheets. At the same time, the speed sometimes reaches 1.2 meters per minute, while maintaining excellent surface quality. Cutting control, fully automatic, takes place with the help of a certain computer program, which is usually already included in the laser installation.
Thanks to this program, you can get at the output of workpieces of any configuration, shape, volume. Of course, the high cost of the installation does not allow this equipment to be used in small production. But for mass or batch production, it is indispensable, since other methods of cutting metal are laborious, and sometimes impossible.
Most laser equipment is based on the principle of a gas or solid-state laser, operating in either pulsed or continuous mode.
There are two types of laser cutting: melting and evaporation. True, the latter method is very energy-consuming, so most industries use the melting method. In such cutting, the molten metal does not enter the cutting channel due to the jet of gas supplied under pressure. This process is called gas laser cutting using inert gas, oxygen or regular air, which is much more economical.
Cutting speed and edge quality are directly related to gas selection. The highest quality cut is obtained when using nitrogen, however, the speed is reduced by almost three times.
Today, laser cutting of metal is ahead of and crowds out other methods for cutting metal. Moreover, it is the most demanded service. Laser cutting is referred to if
- sheet metal has a fairly large thickness (up to 8 mm);
- precision metal cutting is required;
- there is a need to combine the optimal cost of work with high performance;
- it is required to minimize waste by pre-distributing the parts on the sheet;
- minimum deformation of the product must be achieved.
