1) Melt cutting

In this way, when the laser irradiates the surface of the metal material, the laser heat causes it to melt rapidly, passing through the high-pressure inert gas (such as nitrogen, argon, helium, etc.) coaxial with the beam. Blowing molten metal away from the material and then creating a kerf.

2）Vaporization cutting

The surface of the material is irradiated with extremely high power density light to vaporize the material in a very short time, and the vapor is blown away from the surface of the material to form an incision. Vaporization cutting is mostly used for very thin metal materials and non-metal materials, such as plastics, wood, etc.

3) Oxygen cutting

Oxygen, as a combustion accelerant, can react violently with the metal heated to melt by the laser, generating a large amount of oxidation heat. Therefore, oxygen cutting is actually the “aerobic” version of melting cutting. Since metal combustion generates heat, oxygen cutting saves more energy than melting cutting, but the cutting speed is much faster than melting cutting and vaporization cutting. Oxygen cutting is mainly used for cutting easily oxidized metal materials such as carbon steel and titanium steel.

4) Scribing and Controlled Break Cutting

Scribing and cutting use a high-energy-density laser to scan the surface of a brittle material. After the material is heated, it evaporates into a small groove. When a certain amount of pressure is applied to the material, the brittle material will crack along the small groove. Controlled fracture is the steep temperature distribution produced by laser grooving, which creates localized thermal stresses in brittle materials, causing the material to fracture along small grooves. For example the glass cutting.
