What are the factors that affect the processing accuracy of laser metal cutting machine?

What are the factors that affect the processing accuracy of  laser mental cutting machine?
1. Processing material

When the laser mental cutting machine processes metal, the cutting accuracy is different in the face of different materials. Even if it is the same material, if the composition of the material is different, the cutting accuracy will be different. Therefore, the workpiece material also has a certain influence on the laser cutting accuracy. In general, the smoother the material, the higher the processing accuracy.

Therefore, when processing different metal materials, you can make samples in advance to find out the most suitable parameter settings for such materials.

2. The shape of the laser beam

The beam emitted by the laser of the laser mental cutting machine is cone-shaped, so the slit is also tapered. The shape of the laser beam is also a major factor affecting the cutting accuracy of the metal laser cutting machine. The smaller the spot after the laser beam is focused, the smaller the slit and the higher the processing accuracy.

Under the condition of this tapered laser beam, the greater the thickness of the workpiece, the lower the accuracy, so the larger the slit. Therefore, when processing metals of different thicknesses, proper laser power can be selected to obtain better results.

3. Precision of worktable

When the laser mental cutting machine is processing, the worktable vibrates with the vibration of the laser head. High-precision worktable with stable linear guide and stepper motor will increase the cutting accuracy; if the worktable is uneven or other reasons, it will also affect the processing accuracy of the laser mental  cutting machine.

4. Auxiliary gas and nozzle

During the process of  laser mental cutting machine, auxiliary gas and nozzle play the role of cleaning and controlling the cutting speed. The existence of uneven pressure and temperature in the airflow will cause the density of the airflow field to change, thus focusing the beam energy, causing refocusing or beam divergence, and affecting the accuracy of metal cutting.
