Fiber laser is a new type of fiber laser developed in the world, which outputs high-energy density laser beams and gathers them on the surface of the workpiece, so that the area on the workpiece illuminated by the ultra-fine focus spot instantly melts and vaporizes, and the automatic cutting is realized by moving the spot irradiation position through the numerical control mechanical system, with high speed and high precision.
In order to better use the laser cutting machine, let's take a look at what affects the speed of the cutting machine:
1、 Thickness and roughness of materials
Laser cutting is suitable for cutting thin plates. The thickness of carbon steel with good effect is less than 12mm and stainless steel with less than 6mm. The processed quality is significantly enhanced and the efficiency is guaranteed. If the material <1mm is cut, the incision will also be extremely smooth. Material surface roughness also determines the cutting quality. Generally, the smoother the material, the better the cutting quality.
2、 Working power and mode of laser equipment
Research has proved that the higher the power of the laser equipment, the better the effect will be even if cutting the same plate. The mode of laser cutting has a certain degree of agreement with the material.
3、 Focus position
The focus of laser cutting machine can be on, and the precision and accuracy of cutting can meet the desired requirements.
4、 Cutting speed
In fact, no matter what kind of material can make the cutting speed extremely consistent with the material, the cutting effect is better at this time. Too fast or too slow will affect the laser cutting.
5、 Auxiliary gas pressure and type
The higher the pressure of the auxiliary gas, the higher the purity of the gas, the less impurities adhered to the material, and the smoother the cutting edge. Generally speaking, the speed of oxygen cutting is fast, and the cutting effect of nitrogen is good and the cost is low. The cutting effect will vary with different gases.
