What are the advantages of laser cutting?
As a new cutting process, laser cutting is becoming more and more popular in the application field. Laser cutting uses a laser beam to irradiate the surface of the workpiece. Through the conversion between electro-optical and thermal energy, the temperature where the beam hits rises rapidly and the material melts. Pores are formed after gasification. As the beam moves, the hole connections gradually form lines. So what are the advantages of laser cutting? It has these parameters! Take a look!
What are the advantages of laser cutting?
1. Good cutting quality
The laser spot is small, the energy density is high, and good cutting quality can be obtained. The laser cutting seam is narrow, the cutting accuracy error is small, the section is beautiful and clean, the roughness can be accurate to the micron level, the laser cutting hot zone is small, the material is basically not affected by special deformation, and the laser cutting material can be used directly without polishing and other processes.
2. High cutting speed
Laser cutting is highly scalable, equipment work is done through programming, and equipment can be matched with automatic loading and unloading facilities without manual intervention. The working efficiency of laser cutting machine is much higher than that of traditional cutting equipment. Laser cutting does not require fixture tooling, which saves some tooling replacement time for mold material cutting. The cutting work of the equipment can be carried out for a long time, and it is equipped with a water cooling device to keep the equipment at a normal temperature all the time.
3. Non-contact cutting
Laser cutting does not require contact with the workpiece, nor does it require the loss of abrasive tools such as saw blades. When processing various workpieces, there is no need to change the fixture and adjust the cutting parameters. The entire device operates without physical contact and the corresponding noise is minimal. The cutting residue is dust particles, which are easy to clean and have little pollution to the environment.
Laser cutting has these parameters:
1. Laser power
In order to laser cut a material, it is necessary to bring the material to a certain energy. The total energy is multiplied by the laser power times the time the laser beam irradiates the workpiece. For plates of the same material thickness, to achieve the energy required for melting, the higher the laser power, the shorter the cutting time.
2. Working mode
Continuous fiber or pulse type can choose continuous work or intermittent work by adjusting the operation mode. According to different process requirements, selecting the appropriate working method can obtain better processing results.
3. Cutting speed
The cutting speed has a certain influence on the actual cutting effect. Under the same laser power, for example, the speed of 1.2m/min can achieve excellent cutting effect, but after the speed is adjusted to 1.3m/min, the section may have a little rough marks or few uncut parts, if If the speed is too low, the cut section will melt excessively. In principle, the higher the laser power, the faster the cutting speed of the same thickness plate.
