Laser cutting of metal
Are you interested in the technology of laser cutting of metal rolls of metals, steels and alloys from the supplier company AvecGlob? Here you will find interesting information on this topic /
The essence of the process
Lasers are used for many purposes, including cutting metal plates or sheet metal. On soft steel, stainless steel and aluminum plates, the laser cutting process is very precise, gives excellent cutting quality, has a small width and a small heat-affected zone, and also allows you to cut very complex shapes and obtain small cross-sections.
The laser beam is a light column with a very high intensity of the energy beam, with the same wavelength value. In the case of a conventional CO 2 laser, this wavelength is in the infrared region. This is the reduced part of the spectrum of light, so it is invisible to the human eye. The beam is only about 2… 2.5 mm in diameter, when it moves from the laser cavity, which creates a beam through the trajectory of the beam of the machine. It can be directed in different directions by several mirrors, before finally focusing on the plate or sheet, which are subject to cutting.
Sequence of laser cutting
The focused laser beam passes through the nozzle opening just before it hits the plate. Also, a compressed oxygen or nitrogen gas flows through this nozzle opening. Focusing of the laser beam can be performed with a special lens or a curved mirror, this occurs in the laser cutting head.
The beam should be precisely focused in such a way that the shape of the focusing spot and the density of energy in this place are absolutely round and matched in the nozzle.
High power density leads to rapid heating, melting and partial or complete evaporation of the material. When cutting mild steel, the thermal radiation from the laser beam is sufficient to start the cutting process in oxygen. When cutting stainless steel or aluminum, the laser beam simply melts the material, and high-pressure nitrogen is used to blow molten metal out of the cut.
Supplier — the company AvekGlob — offers at affordable prices from the manufacturer various metals and alloys, blanks for which can be obtained using laser cutting. The assortment and the number of such blanks are completely determined by the customer’s wishes. The supplier guarantees the timely delivery of products to any address specified by the consumer
Equipment for laser cutting
On laser cutting machines with CNC, the laser cutting head moves along the metal plate along the contour, which is preset by the control program. The capacitive height control system maintains a very precise distance between the end of the nozzle and the cut plate. This distance is important because it determines where the focal point is relative to the surface of the cut sheet or plate. The quality of the cutting can be influenced by the rise or fall of the focal point directly above the surface of the workpiece, on the surface or under its surface.
Laser cutting is a stable, reliable and very precise cutting process, which is used in precise machine and instrument engineering.
