The working principle of the laser cutting machine is mainly the interaction between the laser and the material, and the action process is mainly divided into two phenomena: microscopic and macroscopic. The microscopic phenomenon is mainly the quantum reaction process, and the macroscopic phenomenon includes the absorption, reflection, refraction, energy conversion and transmission of the laser light by the material. The factors that affect the cutting quality of laser cutting machines are very complicated. In addition to the characteristics of the material itself, there are also some influences on the hardware of the equipment. Let’s take a look at it together.
1. Laser output power and mode
The higher the output power of the laser, the better the cutting quality will be on the same thickness of the plate. The better the laser’s cutting pattern fits the material, the better the cutting quality will be. In addition, it affects the dimensional accuracy of the workpiece, the width of the slit, the roughness of the cutting surface and the width of the heat-affected zone.
2. The thickness of the metal material
The metal laser cutting machine is suitable for cutting thin plates. The cutting effect of carbon steel below 12mm and stainless steel below 6mm is obvious, the quality is the best, and the efficiency can also be guaranteed. For example, when the material thickness is 1mm, the material cut is extremely smooth.
3. The smoothness of the metal surface
In general, the smoother the surface of the material, the better the quality of the cut. Through independent research and development, DXTECHLASERUS laser metal laser cutting machine has an automatic sensing system, which can automatically adjust the height of the cutting head according to the different thickness of the material.
4. Focus position during cutting
It is very simple, the focus of the metal laser cutting machine is aligned, and the precision and accuracy of the cutting can meet the requirements.
5. Cutting processing speed
No matter what kind of material the laser cuts, if the matching between the cutting speed and the material can be achieved the best, then the cutting effect at this time is the best, too fast or too slow will affect the processing effect of the metal laser cutting machine.
6. Pressure and type of auxiliary gas
The higher the pressure, the higher the purity of the gas, the less dross the material adheres to, and the smoother the cut. Different gas types have different cutting speeds and effects. Generally speaking, oxygen cuts the fastest, nitrogen cuts the best, and air cuts the cheapest.
There are many factors that affect the cutting quality of laser cutting machines. Fully understanding various factors in the cutting process of laser cutting machines can find technological ways to improve the surface quality of processed materials and improve the quality of processed surfaces.
