How to extend the life of laser cutting machine?
The main components of the laser cutting machine are circuit system, transmission system, cooling system, light source system and dust removal system. The main points that need to be maintained in the daily life are the cooling system (guaranteeing the constant temperature effect), the dust removal system (guaranteeing the dust removal effect), the optical path system (guaranteeing the beam quality), and the transmission system (the focus is on ensuring normal operation). In addition, a good working environment and correct operating habits also help to extend the life of the equipment.
→First, cooling system maintenance.
The water inside the water cooler needs to be replaced regularly, and the frequency of replacement is usually one week. The water quality and water temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use pure water or distilled water and control the water temperature below 35 °C. It is easy to form scale without changing the water for a long time, thus blocking the waterway, so it is necessary to change the water regularly.
Keep the water flowing at all times. The cooling water is responsible for taking away the heat generated by the laser tube. The higher the water temperature, the lower the light output power (15-20 °C water temperature is better); when the water is broken, the tube end will burst due to heat accumulated in the laser cavity, and even the laser power source may be damaged. . Therefore, it is necessary to check whether the cooling water is unblocked at any time. When the water pipe has a hard fold (dead bend) or falls off, and the pump fails, it must be repaired in time to avoid power loss or even equipment damage.
→Second, dust removal system maintenance.
When the fan is used for a long time, it will accumulate a lot of dust, which will affect the exhaust and deodorization effects, and will also generate noise. When it is found that the suction of the fan is insufficient and the exhaust is not smooth, first turn off the power supply, remove the air inlet pipe and the air outlet pipe on the fan, remove the dust inside, then turn the fan upside down, and move the fan blade inside until it is clean. Then install the fan. Fan maintenance cycle: about one month.
→Third, the optical system maintenance
After the machine is working for a period of time, the surface of the lens will be glued with a layer of ash due to the working environment, thereby reducing the reflectivity of the reflective lens and the transmittance of the lens, ultimately affecting the working power of the laser. At this time, use a cotton wool and ethanol to carefully wipe along the center of the lens to the edge. The lens should be gently wiped to prevent damage to the surface coating; the wiping process should be handled gently to prevent it from falling; be sure to keep the concave surface facing down when installing the focusing mirror. In addition, the number of ultra-high-speed perforations is usually reduced as much as possible, and the use of conventional perforations can extend the life of the focusing mirror.
→Fourth, the transmission system maintenance.
When the equipment is cut for a long time, soot will be generated. Fine dust will enter the equipment through the dust cover and adhere to the rack rack. Long-term accumulation will increase the rack rack wear. The rack guide is a relatively precise accessory. The dust is deposited on the guide rail and the linear shaft surface for a long time, which has a great influence on the machining accuracy of the equipment, and will form an etch point on the surface of the guide rail linear shaft to shorten the service life of the equipment. Therefore, in order to make the equipment work stably and ensure the processing quality of the products, it is necessary to do a good job of routine maintenance of the guide rails and linear shafts, and regularly perform dust removal. After cleaning the dust, grease the rack and lubricate the rails with oil. Each bearing should also be oiled regularly so that the drive can be kept flexible, the machining is accurate, and the service life of the machine tool is extended.
→Fifth, the working environment.
The environment of the workshop should be kept dry and well ventilated. The ambient temperature is between 4 °C and 33 °C. In summer, prevent condensation on the equipment and prevent the freezing of the laser equipment in winter.
The equipment should be kept away from electrical equipment that is sensitive to electromagnetic interference to prevent long-term electromagnetic interference. Away from the sudden large power disturbances of large power and strong vibration equipment, large power disturbances sometimes cause machine malfunction, although it is rare, it should be avoided. Therefore, such as large electric welders, giant electric mixers and large-scale power transmission and transformation equipment, etc., should be far away. Strong vibration equipment is self-evident, such as forging presses, vibrations caused by walking of close-range motor vehicles, etc., the obvious jitter of the ground is very unfavorable for precise engraving.
→Sixth, other matters needing attention.
During the operation of the equipment, the operator must observe the working condition of the equipment at any time. If abnormal conditions occur, immediately cut off all power sources, promptly eliminate the faults or report to the supervisors, and take appropriate measures. Regularly count the use of the machine, and keep a record of each part of the laser cutting machine regularly. If it is not effective, replace it in time to prevent it from happening.
Do not process a material before it can be irradiated or heated with a laser to avoid the potential hazard of smoke and vapor and damage the laser equipment.
If you follow the maintenance skills above smoothly, I believe that your Laser Cutting Machine will last longer and work more efficiently!
