Several cutting methods of laser cutting machine

As the name suggests, a laser cutting machine is a device for cutting processing by laser. The cutting machine equipment will choose different cutting methods according to the material of the processing material. So the following editor will introduce in detail several cutting methods of laser cutting machine.
  1, laser vaporization cutting
Laser vaporization cutting is a high-energy and high-density laser beam used by the laser cutting machine to heat the workpiece, increase the temperature, and vaporize the material into steam in a short time. When the steam is ejected, it will be on the material. A cut is formed, so that the cutting effect is achieved. However, the heat of vaporization of general materials is very large, so high-power laser beams should be used when the materials are heated. The materials used in laser vaporization cutting generally include thin metal materials and non-metal materials.
  2, laser melting and cutting
   Laser melting cutting is a laser cutting machine that heats the material to a certain temperature and melts it, and then sprays non-oxidizing gas through a nozzle coaxial with the beam, and uses the gas pressure to discharge the liquid metal to form an incision. The energy required for laser melting and cutting is only 1/10 of that of vaporization cutting, and the metal does not need to be completely vaporized. Generally, the materials suitable for laser melting and cutting are stainless steel, titanium, aluminum and their alloys, etc., which are all materials or active metals that are not easily oxidized.
  3, laser oxygen cutting
  Laser oxygen cutting is a laser cutting machine that uses a laser as a preheating heat source, and an active gas such as oxygen as an auxiliary gas for cutting. After the gas is ejected, the gas and the metal are oxidized and a large amount of oxidation heat is released. At the same time, the molten oxide and melt are blown out of the reaction zone to form a cut in the metal. Generally, the materials suitable for laser oxygen cutting are carbon steel, titanium steel, heat-treated steel and other easily oxidized metal materials.
  4. Laser scribing and controlled fracture
  Laser scribing and controlled fracture use a high-energy density laser beam to scan the surface of the material. The outside of the material is heated to emit a small groove, and then a certain pressure is applied, so the laser will cut along this small groove. This kind of cutting generally uses brittle materials.
  The cutting methods used by the laser cutting machine when facing different materials are also different, so when you operate and use the equipment, you need to pay more attention to avoid wrong operation and affect the cutting quality of the equipment.
