When many people buy a laser cutting machine, they will care about the accuracy of the machine. To a large extent, accuracy has become a standard for measuring the quality of a machine. There are many factors that affect the accuracy of laser cutting, of course, there are factors of the equipment itself, but at the same time, the accuracy also changes with the factors of materials, materials and other factors.
1. Cutting material: Under the same circumstances, the cutting accuracy of different materials is slightly different. Even if it is the same material, if the composition of the material is different, the cutting accuracy will also be different. Generally speaking, under the same circumstances, the smoother the material, the higher the cutting accuracy;
2. Auxiliary gas and nozzle: During laser cutting, the auxiliary gas and nozzle play a role in cleaning and controlling the cutting speed to a certain extent. If there is uneven pressure and temperature in the airflow, it will cause a change in the airflow field density. Such a density gradient causes the refractive index in the field to change, thereby focusing the beam energy, causing refocusing or beam divergence.
