Precision CNC Laser Metal Cutting Parts CNC Sheet Metal Parts

Laser cutting parts use a focused high-power density laser beam to irradiate the workpiece, so that the irradiated material rapidly melts, vaporizes, ablates or reaches the ignition point. cut open. Laser cutting is one of the thermal cutting methods.

1) Laser vaporization cutting

A laser beam with high energy density is used to heat the workpiece, so that the temperature rises rapidly, reaching the boiling point of the material in a very short time, and the material begins to vaporize to form vapor. These vapors are ejected at a high velocity, and at the same time as the vapors are ejected, cuts are formed in the material. The vaporization heat of the material is generally large, so a large power and power density are required for laser vaporization cutting.

Laser vaporization cutting is mostly used for the cutting of extremely thin metal materials and non-metallic materials (such as paper, cloth, wood, plastic and rubber, etc.).

2) Laser melting cutting

When laser melting and cutting, the metal material is melted by laser heating, and then non-oxidizing gas (Ar, He, N, etc.) is sprayed through a nozzle coaxial with the beam, and the liquid metal is discharged by the strong pressure of the gas to form a cut. Laser melting cutting does not need to completely vaporize the metal, and the energy required is only 1/10 of the vaporized cutting.

Laser melting cutting is mainly used for cutting materials that are not easily oxidized or active metals, such as stainless steel, titanium, aluminum and their alloys.

3) Laser oxygen cutting

The principle of laser oxygen cutting is similar to that of oxyacetylene cutting. It uses a laser as a preheating heat source and an active gas such as oxygen as a cutting gas. On the one hand, the blown gas interacts with the cutting metal to produce an oxidation reaction, releasing a large amount of oxidation heat; on the other hand, the molten oxide and melt are blown out from the reaction zone to form a cut in the metal. Since the oxidation reaction in the cutting process generates a lot of heat, the energy required for laser oxygen cutting is only 1/2 of the melting cutting, and the cutting speed is much higher than that of laser vapor cutting and melting cutting. Laser oxygen cutting is mainly used for easily oxidized metal materials such as carbon steel, titanium steel and heat-treated steel.

4) Laser scribing and controlled fracture

Laser scribing uses a high-energy-density laser to scan the surface of a brittle material, so that the material is heated and evaporated into a small groove, and then a certain pressure is applied, and the brittle material will crack along the small groove. The lasers used for laser scribing are generally Q-switched lasers and CO2 lasers.
