Laser cutting machine can be used for metal and non-metal cutting. Use a laser beam to melt the surface of the material. This paper will introduce the advantages and cutting methods of laser cutting machine.

Advantages of laser cutting machine

1. Efficient

Due to the transmission characteristics of laser, laser cutting machines are usually equipped with multiple NC workbenches, and can completely control the entire cutting process. In the running process, the NC program can be applied to the cutting of parts with different shapes by changing the NC program, so that 2D cutting and 3D cutting can be carried out.

2. Fast

The 1200W laser can cut 2mm thick low carbon steel plate, and the cutting speed can reach 600cm/min; For 5mm thick polypropylene resin board, the cutting speed can reach 1200cm/min. In the process of laser cutting, there is no need to clamp and fix the material.

3. Good cutting quality

3.1: The laser cutting incision is narrow, both sides of the incision are parallel and perpendicular to the surface, and the dimensional accuracy of the cutting part can reach ± 0.05mm.

3.2: The cutting surface is smooth and beautiful, and the surface roughness is only tens of microns. Even if there is no machining, laser cutting can also be used as the final process, and parts can be used directly.

3.3: After the material is laser cut, the width of the heat affected zone is very small, and the material properties near the slit are almost unaffected. The workpiece deformation is small, the cutting accuracy is high, the geometric shape of the slit is good, and the cross section shape of the slit is relatively regular.

4. Cutting non-contact

In the process of laser cutting, there is no direct contact between the cutting torch and the workpiece, and there is no tool wear. To process parts with different shapes, it is not necessary to change the "tool", just change the output parameters of the laser. The laser cutting process has low noise, small vibration and little pollution.

5. More cutting materials

Compared with oxyacetylene cutting and plasma cutting, there are many types of laser cutting materials, including metal, non-metal, metal matrix and non-metal matrix composites, leather, wood and fiber.

Advantages and cutting methods of laser cutting machine?

Cutting method of laser cutting machine

1. Vaporization cutting

It means that the removal of processing materials is mainly carried out through evaporation of materials.

2. Reaction melting cutting

In melt cutting, the auxiliary air flow not only blows away the molten material in the cutting seam, but also reacts with the workpiece, thus increasing the heat source in the cutting process. This cutting is called reactive melt cutting. Generally, the gas that can react with the workpiece is oxygen or a mixture containing oxygen.

3. Fusion cutting

In the process of laser cutting, if an auxiliary blow molding system coaxial with the laser beam is added, the removal of molten material in the cutting process is not only due to the vaporization of the material itself, but also mainly due to the blow molding of high-strength materials. Accelerate the auxiliary air flow to remove molten material. The cutting process is called melting cutting.

4. Laser scribing

The method is mainly used for: semiconductor materials; Use a high power density laser beam to draw a shallow groove on the surface of the semiconductor material workpiece, because the groove will weaken the bonding force of the semiconductor material. It can be broken by mechanical method or vibration method. The quality of laser scribing is measured by the size of surface debris and heat affected zone.
