The so-called metal cutting machine is also called metal laser cutting machine. It is the energy released when the laser beam is irradiated on the surface of the metal workpiece to melt and evaporate the metal workpiece to achieve the purpose of cutting or carving. Cutting pattern limitation, automatic typesetting save material, smooth cut, low processing cost and other characteristics.
The metal cutting machine is divided into high-power metal cutting machine, optical fiber metal sheet cutting machine, and metal engraving and cutting integrated machine according to the laser power.
The laser metal cutting process also adds auxiliary gas suitable for the material being cut. When cutting steel, it is necessary to use oxygen as an auxiliary gas to generate an exothermic chemical reaction with the molten metal to oxidize the material, and at the same time help to blow away the slag in the slit. For metal parts that require high processing accuracy, nitrogen can be used as an auxiliary gas in the industry.
Most organic and inorganic materials can be cut with a laser. In the metal processing industry, where industrial production takes a large part, many metal materials, regardless of their hardness, can be cut without deformation (the thickness of industrial steel can be approached by using the most advanced metal laser cutting machine) 20mm). Of course, for highly reflective materials, such as gold, silver, copper, and aluminum alloys, they are also good heat transfer conductors, so laser cutting is difficult or even impossible (some difficult-to-cut materials can be cut with a pulsed laser beam, Due to the extremely high peak power of the pulse wave, the absorption coefficient of the material to the beam can be sharply increased instantaneously).
As a new type of tool, metal cutting machines are increasingly used in various industries. Used in metal cutting, textile fabric cutting, laser marking, laser engraving, etc.
