The main components of metal optical fiber laser cutting machine are circuit system, transmission system, cooling system, light source system and dust removal system. The parts to be protected for daily key points are mainly cooling system (to ensure constant temperature), dust removal system (to ensure dust removal), light path system (to ensure beam quality) and transmission system (to ensure normal operation for key points). In addition, good operating environment and correct operating habits are also conducive to extending the service life of equipment. How to maintain the equipment during the operation of the laser machine?

1、 Cooling system maintenance

The water inside the chiller needs to be replaced regularly, and the general replacement frequency is one week. The quality and temperature of 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 ℃. If the water is not changed for a long time, it is easy to form scale and then block the waterway, so the water must be changed regularly.

2、 Keep the water flowing at any time. 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 (preferably 15-20 ℃); When the water is cut off, the tube end will burst due to heat accumulation in the laser cavity, and even damage the laser power supply. Therefore, it is necessary to check whether the cooling water is unblocked at any time. When the water pipe has a hard break (dead bend) or falls, so that the water pump fails, it is necessary to repair it in time, so as to avoid power drop or even damage to the metal optical fiber laser cutting machine.

3、 Dust removal system maintenance

After long-term use, the metal optical fiber laser cutting machine fan will accumulate a lot of dust, which will affect the exhaust and deodorization, and will also generate noise. If it is found that the suction of the fan is insufficient and the smoke exhaust is not smooth, first close the power supply, remove the air inlet pipe and air outlet pipe on the fan, remove the dust inside, then turn the fan upside down, move the blades inside until they are clean, and then install the fan properly.

After the machine works for a period of time, the surface of the lens will be covered with a layer of dust due to the working environment, and then the reflectivity of the mirror and the transmittance of the lens will be reduced, which will affect the operating power of the laser. At this time, use absorbent cotton dipped in ethanol to carefully scrub the intestine along the center of the lens to the edge. The lens shall be lightly scrubbed, and the coating on the surface shall not be damaged; The scrubbing process shall be handled with care to prevent falling; The concave surface must be downward when focusing the mirror device.

4、 Drive system maintenance

The metal optical fiber laser cutting machine will produce smoke and dust in the long-term cutting process. The fine smoke and dust will enter the equipment through the dust cover, and then attach to the rail rack. Long term accumulation will add rail rack wear. The rack guide rail is a relatively precise accessory. Dust accumulates on the surface of the guide rail and linear shaft for a long time, which has a great impact on the processing accuracy of the equipment, and will form corrosion spots on the surface of the linear shaft of the guide rail, shortening the service life of the equipment. Therefore, in order to ensure the normal and stable operation of the equipment and the processing quality of the products, we must carefully do a good job in the daily protection of the guide rail and the linear shaft, and regularly do dust removal. After cleaning up the dust, grease the rack and lubricate the guide rail with lubricating oil. The bearings should also be oiled regularly, so as to maintain sensitive driving, accurate machining and extend the service life of the machine tool.
