Fiber Laser Cutting Machine

What is a metal laser cutting machine?
Metal laser cutting machine is a kind of CNC laser cutting machine for sheet metal, metal plate, metal profile, metal tube and metal tube. It is the best metal cutting solution for metal manufacturers. Metal laser cutting machine can be used for 2D/3D metal of stainless steel, galvanized steel, carbon steel, low carbon steel, cold rolled steel, hot rolled steel, copper, brass, alloy, iron, silver, gold, titanium, aluminum, bronze Cutting project. Laser metal cutting machine is equipped with frame, laser power supply, laser generator, reflector path, laser cutting head, water cooler, control panel and CNC (computer numerical control) system.

How does a metal laser cutting machine work?
The energy of the laser is concentrated into a high-density beam in the form of light. The laser beam is transmitted to the working surface to generate enough heat to melt the material. The high-pressure gas coaxial with the beam directly removes the molten metal to achieve the purpose of metal cutting. It can be seen that there is a fundamental difference between laser metal cutting and CNC machining. The laser metal cutting machine uses the laser beam emitted by the laser generator to focus on the laser beam irradiation conditions of high power density through an external circuit system. The laser heat is absorbed by the workpiece material, and the temperature of the workpiece rises sharply. After reaching the boiling point, the material begins to vaporize and form holes. As the relative position of the beam and the workpiece moves, a gap will eventually be formed in the material. The process parameters (cutting speed, laser power, gas pressure, etc.) and movement trajectory during slitting are controlled by the numerical control system, and the slag at the slit is blown away by a certain pressure of auxiliary gas. When laser cutting metal, it is necessary to add auxiliary gas suitable for the material to be cut. When cutting steel, oxygen must be used as an auxiliary gas to produce an exothermic chemical reaction with the molten metal to oxidize the material and at the same time help blow away the slag in the slit. For metal parts with high machining accuracy, nitrogen can be used as an auxiliary gas in the industry.
