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

Compared with the traditional production process, the metal laser cutting machine has higher processing accuracy and stronger cross-sectional effect, without secondary production processing. This is also the reason why many companies choose metal laser cutting machines. As everyone knows, many companies have found that the laser cutting precision of fiber laser cutting machines and equipment is sometimes not ideal. So what are the aspects that affect the processing accuracy of the metal laser cutting machine?

1. Production and processing materials

When fiber laser cutting produces and processes metal materials, the precision of laser cutting for different materials is different. Even if it is the same material, if the composition of the raw material is not the same, the precision of laser cutting will be different. Therefore, the workpiece material of the product is also harmful to the precision of fiber laser cutting. In general, the smoother the raw material, the higher the processing accuracy.

Therefore, when producing and processing different metal materials, samples can be carried out beforehand, and the most suitable basic parameters for this type of material can be explored.

2. The appearance of laser light

The light from the laser generator of the metal laser cutting machine is cone-shaped, so the cut gap is also cone-shaped. The appearance of laser light is also a major factor that endangers the precision of laser cutting of metal laser cutting machines. After the laser is concentrated, the light spot is small, the slit is small, and the processing accuracy is high.

Under this kind of cone laser light standard, the thickness of the product workpiece will also affect the level of precision, so kerf appears. Therefore, in the production and processing of different thin and thick metal materials, a strong practical effect can be obtained by selecting a suitable laser output power.

3. The precision of the console

During the production and processing of the metal laser cutting machine, the operating table vibrates along with the vibration of the laser cutting head. The high-precision operating table is equipped with a stable linear slide and servo motor, and the precision of laser cutting will increase; if the operating table is uneven or other reasons, it will also harm the processing accuracy of fiber laser cutting.

4. Auxiliary steam and nozzle

During the production process of the metal laser cutting machine, the auxiliary vapor body and the nozzle play the function of cleaning and controlling the laser cutting rate. The uneven working pressure and temperature in the cyclone will cause a change in the relative density of the cyclone field, which will cause the focus of the kinetic energy of the light to be focused, resulting in refocusing or light emission, and endangering the precision of laser cutting of metal materials.
