Factors affecting the processing quality of laser cutting machine

Laser cutting is a more common processing method in laser processing, and it is also a relatively simple one. The processing quality of the laser cutting machine is mainly reflected in the processing accuracy and surface quality, and the cutting surface quality is determined by the slit width of the incision and its surface roughness, the range of the heat affected zone, the ripple of the incision section and whether there is hanging slag. The main factors affecting the cutting quality of the material surface are as follows:

First of all, laser power is one of the important factors affecting the processing quality of laser cutting machine. Lower power may result in an inability to penetrate the material completely, resulting in an incomplete or non-smooth cut. Too high a power may cause excessive melting and oxidation, causing the incision to deform or crack, so be sure to configure the right power. Secondly, the focal length also has a significant impact on the processing quality of the laser cutting machine. Choosing the right focal length can ensure that the energy is focused on the desired location and achieve accurate and clear cutting results. If the focus position deviates from the predetermined position, it may lead to a dimensional error of the part or an increase in surface roughness.

In addition, in the process of laser cutting machine, air flow and nozzle design is also one of the key factors. In laser cutting, the airflow can blow away the molten material, protect the focusing lens and even provide part of the cutting energy. Proper adjustment of air pressure can effectively remove slag and prevent burns from clogging nozzle orifice; At the same time, optimizing the nozzle structure can provide better flow and more stable and uniform purging effect. A final factor to consider is the need to know the properties of the material being processed. Different materials, shapes and thicknesses will affect laser energy absorption, transmission and scattering. For example, there are some reflective materials in metal materials, and the reflection problem needs to take corresponding measures to reduce the reflection loss.In non-metallic materials, the appropriate parameters need to be determined according to their absorption characteristics.

Many factors work together on the processing quality of the laser cutting machine, and there is a complex interactive relationship between each other. By effectively adjusting these influencing factors and optimizing the adjustment according to the specific situation, the cutting quality can be higher and the processing can be completed more stably and reliably.
