What is the purpose of laser metal cutting machine?

- 2022-12-29-

Laser cutting machine is broadly used in many industries and a variety of materials.

Sheet steel processing, marketing and signal making, excessive and low voltage electrical cupboard making, mechanical parts, kitchenware, automobile, machinery, steel handicrafts, saw blades, electrical parts, glasses industry, spring sheets, circuit boards, electric powered kettles, scientific microelectronics, hardware, knives and measuring equipment and different industries.


Laser cutting generally has the following main purposes:

1) Laser vaporization cutting uses high energy density laser beam to heat the workpiece, so that the temperature rises rapidly and reaches the boiling point of the material in a very short time. Time, the material begins to evaporate and form steam. The steam is ejected at a high speed, and at the same time, a notch is formed in the material. The heat of vaporization of materials is generally large, so laser vaporization cutting requires large power and power density. Laser vaporization cutting is mainly used for cutting extremely thin metal materials and non-metallic materials (such as paper, cloth, wood, plastic and rubber).

2) Laser fusing When laser fusing, the metal material is melted by laser heating, and then non oxidizing gases (Ar, He, N, etc.) are ejected from the nozzle coaxial with the beam, and the liquid metal is discharged by the strong pressure of the gas, Make a cut. Laser melting cutting does not need to completely vaporize the metal, and the required energy is only 1/10 of that of vaporization cutting. Laser melting cutting is mainly used to cut materials that are not easy to be oxidized or active metals, such as stainless steel, titanium, aluminum and their alloys.

3) The principle of laser oxygen cutting is similar to that of oxyacetylene cutting. It uses laser as preheating heat source and active gas such as oxygen as cutting gas. On the one hand, the blown gas acts on the cutting metal, generating oxidation reaction and releasing a large amount of oxidation heat; On the other hand, molten oxides and molten materials are blown out of the reaction zone, forming a notch in the metal. The oxidation reaction in the cutting process will generate a lot of heat, so the energy required by laser oxygen cutting is only 1/2 of that of melting cutting, and the cutting speed is far higher than that of laser vaporization cutting and melting cutting. Laser oxygen cutting is mainly used for carbon steel, titanium steel, heat treatment steel and other easily oxidized metal materials.

4) Laser scribing and controlled fracture laser scribing use high energy density laser to scan the surface of brittle materials, so that the materials are heated and evaporated into small grooves, and then apply certain pressure, so that the brittle materials will crack along the small grooves. Open. The lasers used for laser scribing are generally Q-switched lasers and CO2 lasers. Controllable fracture is to use the steep temperature distribution generated by laser slotting to generate local thermal stress in the brittle material, so that the material breaks along the small groove.

From the above points, the XT Laser team has summarized the following advantages.

The laser cutting machine reduces the production cost of industrial manufacturing enterprises. Traditional industrial processing equipment mainly uses conventional tools for cutting. In the aspect of machining effect, the cutting surface of the workpiece after cutting is rough and uneven, which requires secondary machining and grinding. Secondly, the tool will also cause wear and needs to be replaced frequently. Compared with the laser cutting machine, the cut workpiece is formed once without the need for secondary grinding process, saving time, labor and manpower, and greatly improving the production efficiency. The laser cutting machine uses the electro-optic conversion principle to cut the workpiece, so as to realize the cutting without contacting the workpiece. So there will be no tool wear. From the above, the laser cutting machine has greatly reduced the production cost of the enterprise.

Laser cutting machine can bring production efficiency to industrial manufacturing enterprises. Before cutting the workpiece, the traditional industrial processing will carry out a series of complex operations such as measuring and drawing lines on the workpiece, wasting time. However, laser cutting machine uses computer control technology to achieve cutting. As long as the cutting program is input into the computer, the laser cutting machine can easily achieve perfect cutting according to the program, saving time and manpower. The second is cutting speed. The cutting speed of the laser cutting machine is several times that of the traditional cutting machine, which shortens the processing time.

The advantages of laser cutting machine compared with CO2 laser cutting machine and YAG laser cutting machine are mainly reflected in the high photoelectric conversion rate, low power consumption, and the ability to cut stainless steel plates and carbon steel plates. When cutting the same thick plate, the laser cutting machine has the fastest cutting speed, small cutting seam, good spot quality and the highest accuracy. Therefore, these traditional cutting methods will be gradually eliminated in the future.
