A laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing it to reach its melting or boiling point, while the high-pressure gas coaxial with the beam blows away the melted or vaporized metal. As the beam of light moves relative to the workpiece, it ultimately forms a cutting seam in the material, thereby achieving the purpose of cutting.

During the cutting process of a laser cutting machine, both the laser head and laser generate a large amount of heat. The function of a chiller is to provide water circulation cooling for the laser generator to reduce the temperature of the laser and ensure the normal operation of the laser cutting machine.

So, how should the chiller of a laser cutting machine be maintained in winter? Zhancheng Laser answers for you:

Firstly, the circulating cooling water in the chiller should be regularly replaced during winter.

The circulating cooling water in the chiller is prone to scale formation due to long-term use. To ensure the normal operation of the chiller, it is recommended that you replace the circulating cooling water every 1-3 months. Large chillers are usually equipped with filters, and the filter element of the filter should also be cleaned and replaced regularly. It is recommended to replace the filter element every six months to ensure the filtration of water quality.

Secondly, when the winter ambient temperature is below 0 ℃, the chiller may experience icing, which can easily damage the chiller and laser equipment. Therefore, it is recommended that you add appropriate antifreeze to the circulating water of the chiller, or keep the chiller running continuously for 24 hours to avoid icing. When the equipment needs to be shut down for a long time, it is necessary to drain the water inside the chiller, cutting head, laser and other equipment to prevent freezing damage.

Finally, the chiller needs to be placed in a ventilated and cool environment during daily use, without stacking obstacles, to ensure the safe operation of the chiller. At the same time, it is necessary to regularly clean the condenser and dust filter.
