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 device itself, but at the same time, the accuracy also changes with the factors of materials and materials.
External 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 the laser cutting process, 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.
Factors of the equipment itself:
1. The quality of the laser beam: the smaller the spot after the laser beam is concentrated, the smaller the slit, and the higher the processing accuracy;
2. The vibration level of the worktable: When laser cutting, the worktable vibrates with the vibration of the laser head. High-precision worktable with stable linear guide and stepper motor, the higher the cutting accuracy;
What needs to be recognized is that the accuracy of the laser cutting machine is not only related to the equipment itself, but also to external factors. When we use the laser cutting machine, we must set and adjust the relevant parameters of the equipment according to the specific processing materials and user quality requirements, such as: power, focus position, cutting speed, auxiliary gas, etc. Meet the user's requirements for product accuracy.
