Compared with the traditional manufacturing process, the metal laser cutting machine has higher processing accuracy and stronger cross section actual effect, so there is no need for secondary production processing. This is also the reason why many companies choose the metal laser cutting machine. However, many companies have found that the laser cutting precision of optical fiber laser cutting machines and equipment is sometimes not ideal,. So what are the influences on the machining accuracy of metal laser cutting machine?

1. Production and processing materials

When optical fiber laser cutting is used to produce and process metal materials, the laser cutting precision of different materials should be different. Even for the same material, if the composition of raw materials is different, the precision of laser cutting will also be different. Therefore, the workpiece material of the product also has certain harm to the precision of optical fiber laser cutting. Generally, the smoother the raw material is, the higher the machining precision is.

Therefore, in the production and processing of different metal materials, sampling can be carried out in advance to explore the most appropriate basic parameters for this type of material.

2. The appearance of laser light

The light from the laser generator of the metal laser cutting machine is conical, so the gap cut is also conical. The appearance of laser light is also a major factor that endangers the precision of metal laser cutting machine. When the light spot is small after the laser is concentrated, the kerf is small and the processing accuracy is high.

In this kind of tapered laser light standard, the thickness of the product workpiece will also affect the precision, so slitting occurs. Therefore, in the production and processing of different thin and thick metal materials, selecting the appropriate laser output power can get a strong practical effect.

3. Precision of console

During the production and processing of metal laser cutting machine, the operating platform vibrates with the vibration of the laser cutting head. The precision of laser cutting will be increased if the high-precision console is matched with a stable linear slide rail and a servo motor; If the operating platform is uneven or for other reasons, it will also endanger the precision of optical fiber laser cutting.

4. Auxiliary steam body and nozzle

In the production process of metal laser cutting machine, the auxiliary steam body and nozzle play the role of cleaning and controlling the laser cutting rate. The uneven working pressure and temperature in the cyclone will cause the transformation of the relative density of the cyclone field, which will further dry up the focusing of light kinetic energy, resulting in refocusing or light emission, endangering the precision of metal material laser cutting.
