The air humidity is high in summer due to the rising temperature. As the saying goes, sharpening the knife will not hurt the firewood cutter. Temg Electromechanical Co., Ltd. withdraws that learning the scientific maintenance of the laser cutting machine can not only avoid some minor failures, improve the cutting efficiency, but also improve the service life of some accessories.
1、 Avoid condensation of dew
The temperature of cooling water shall not be too different from that of air. The laser and optical lens of the laser cutting machine are both water-cooled. As the water in the air will condense into water when it is cold, when the temperature of the cooling water is 5-7 degrees lower than the room temperature, there will be dew condensation on the surface of the laser and optical lens, which greatly affects the light output efficiency of the laser and the transmission of the optical lens, and has a great impact on the laser energy and the service life of the optical accessories. It is recommended that the majority of laser cutting machine users set the water temperature at 30-32 degrees, and control the temperature difference between cooling water and room temperature to be greater than 7 degrees.
Damp and hot weather will also make RF laser inside and outside, glass laser tube outside and around, laser power supply and various parts of laser equipment wet or dewy, which will lead to a variety of failures, thus seriously affecting the normal production of users. The fault caused by the above reasons is not within the normal warranty scope.
At this time, it should be noted that:
1. When the laser equipment is shut down, the water cooler should also be shut down to prevent moisture or condensation under shutdown due to excessive temperature difference;
2. It is recommended that the air conditioner should not be turned off in harsh environments to keep the indoor temperature constant. Or every time you start the machine, turn on the air conditioner for half an hour and then turn on the power of the chiller and laser equipment.
3. The laser equipment is of open design. It is recommended to isolate the air conditioning room to control the indoor temperature and humidity, which is equivalent to that the laser equipment works in an isolated space (no dust, no humidity and constant temperature), which can effectively avoid failures caused by moisture or condensation and high temperature;
2、 Maintain cooling system and cooling water
As the temperature rises in summer, the working pressure of the cooling system of the laser cutting machine increases. It is recommended to check and maintain the internal snow pressure of the cooler before the high temperature comes. The equipment pressure of different manufacturers is also different. It is recommended to consult the specific parameters of the equipment manufacturer before maintenance.
Due to the high temperature in summer, the deterioration rate of cooling water will also be accelerated. It is recommended that users of laser cutting machines use regular distilled water or pure water, and regularly clean the scale, so as not to cause the scale attached to the laser and the pipe to affect the laser power. Different types of laser cutting machines have different methods for cleaning scale. Please operate under the guidance of the equipment manufacturer.
3、 Guide rail maintenance
The guide rail shall be cleaned regularly to remove dust and other sundries, and ensure that the laser equipment's normal rack is wiped and lubricated regularly to ensure that it is lubricated and free of sundries. Regularly clean and lubricate the machine, so that the machine can be in a better position and cut more accurately, and the quality of the cut products will be improved.
4、 Metal laser cutting machine
As the dust of metal laser cutting machine is mainly metal powder, it is recommended to regularly clean the dust in the gas cabinet of the laser cutting machine and check the working condition of the cooling fan.
The laser cutting head is fragile in the metal laser cutting machine. After a long time, the laser cutting head is damaged. Regular inspection and maintenance. If there is deformation or other appearance, you should know that the laser cutting head has been damaged, and replace it. If it is not changed, the cutting quality will be affected and the cost will be increased. Some products may need to be treated twice to reduce production efficiency. Look for professional production laser head cutting, and carefully check when purchasing to avoid the problem of time use.
5、 Summary
The climatic characteristics of each season vary greatly. Laser cutting machines are expensive processing and equipment with high precision requirements. Scientific and orderly maintenance based on climatic characteristics can effectively avoid minor problems in the laser cutting process and improve the service life of laser cutting machines.
