laser cutting machine common cutting method

In modern society, the use of laser cutting machines is very wide. What are the common laser cutting methods? Presumably, many people don't know. Now, Junyi has come to popularize some common cutting methods for laser cutting machines. I hope that you can learn more about the intractable diseases of related laser cutting machines.

laser cutting machine common cutting method 1: laser melting cutting

When using a laser to melt and cut, the metal object is heated and melted by a laser beam, and then a non-oxidizing gas (Ar, He, N, etc.) is blown through a nozzle coaxial with the beam, and the liquid metal is discharged by the strong pressure of the gas. An incision is made. And the laser melt cutting does not need to completely vaporize the metal, and the required energy is only 1/10 of the vaporization cut.

This laser melt cutting is mainly used for the cutting of some non-oxidizable materials or active metals, such as stainless steel, titanium, aluminum and their alloys. It is also a laser cutting machine cutting method developed by Jiatai Laser Technology Co., Ltd.

laser cutting machine common cutting method 2: laser vaporization cutting

A high energy density laser beam is used to heat the workpiece, causing the temperature to rise rapidly and reach the boiling point of the material in a very short time, and the material begins to vaporize to form a vapor. The steam is ejected at a very high speed, forming a slit in the material as it is ejected. The vaporization heat of the material is large, so laser vaporization requires a large amount of power and power density.

Laser vaporization cutting is often used for cutting very thin metal and non-metallic materials such as paper, cloth, wood, plastics and rubber.

laser cutting machine common cutting method 3:laser oxygen cutting

The principle of laser oxygen cutting is similar to oxyacetylene cutting. It uses a laser as a preheating heat source and uses an active gas such as oxygen as a cutting gas. The injected gas reacts with the cutting metal on the one hand to generate a large amount of heat of oxidation; on the other hand, the molten oxide and the molten material are blown out from the reaction zone, and a gap is formed in the metal. Since the oxidation during the cutting process generates a large amount of heat, the energy required for laser cutting oxygen is only 1/2 of that of melting and cutting, and the cutting speed is much greater than laser vaporization cutting and melt cutting. Laser oxygen cutting is now mainly used by metal laser cutting machines to cut easily oxidizable metal materials such as carbon steel, titanium steel and heat-treated steel.

laser cutting machine common cutting method 4: laser dicing and control fracture

Laser scribing is performed by scanning a high-energy-density laser on the surface of a brittle material. After the material is heated, it evaporates into a small groove, and then a certain pressure is applied, and the brittle material is cracked along the small groove. Lasers for laser scribing are generally Q-switched lasers and CO2 lasers.

Controlling fracture is a steep temperature distribution created by laser grooving, which creates local thermal stresses in the brittle material that cause the material to break along the small grooves.
