Factors Affecting The Surface Roughness Of Laser Cutting

Laser Equipment Manufacturer believes that laser cutting surface roughness mainly depends on the following three aspects:

1. Intrinsic parameters of the cutting system, such as spot mode, focal length, etc.

2. Process parameters that can be adjusted during the cutting process, such as power size, cutting speed, auxiliary gas type and pressure;

3. Physical properties of the processed material, such as the absorption rate of the laser, the melting point, the viscosity coefficient of the molten metal oxide, and the surface tension of the metal oxide.

In addition, the thickness of the workpiece also has a large effect on the quality of the laser cut surface. Relatively speaking, the smaller the thickness of the metal workpiece, the higher the roughness level of the cutting surface, so choosing a suitable Laser Cutting Machine has a positive effect on improving production efficiency.
