How to extend the service life of laser cutter?

The laser cutter is a tool inmanufacturer’s production, the quality and service are very important, the maintenance is also very important. We will share how to extend the service life of laser cutter in this article.

Firstly, maintenance of the optical system  of  laser  cutter

After the device has been running for a period of time, some dust will stick to the surface of the lens. This dust will have a great impact on the reflectance of the lens and the transmittance of the lens, which will reduce the power of the laser. At this time, it is necessary to clean the lens. The dust, but you must be careful when cleaning up. The lens is a damaged item. Please handle it gently. Do not touch the lens with sharp or hard objects.

The steps and precautions for cleaning the lens are as follows: First, use absorbent cotton dipped in ethanol to wipe carefully along the center to the edge of the lens. The lens needs to be wiped gently, and the surface coating should not be damaged. Be sure to keep the concave surface down when installing the focusing lens. In addition, the use of ultra-high-speed piercing should be minimized at ordinary times. And the use of conventional piercing can prolong the service life of the focusing lens.

Secondly, maintenance of the dust removal system of laser cutter

The dust removal fan will accumulate a lot of dust after long-term use. If it is not cleaned regularly, it will lead to insufficient wind power and unsmooth smoke exhaust. This will affect the effect of exhaust deodorization and generate a lot of noise. You must pay attention to it during the cleaning process. To be safe, first turn off the power and remove the device on the fan. First remove the inlet and outlet ducts, clean up the dust inside, turn the fan upside down, flip the fan blades inside until it is clean, and then install the fan. It is best to keep the fan cleaned once a month.

Thirdly, maintenance of the transmission system of laser cutter

During the long-term cutting process of the equipment, will generate dust and smoke. Small smoke and dust will enter the equipment through the dust cover and adhere to the rail rack. Long-term accumulation will increase the wear of the rail rack. Rack guide rails are relatively precise accessories. Large amounts of dust are on the surfaces of guide rails and linear shafts for a long time, which has a great impact on the processing accuracy of the equipment. And will form corrosion points on the surface of the linear shaft of the guide rails, shortening the service life of the equipment.

Therefore, in order to make the equipment work normally and steadily and ensure the processing quality of the products, it is necessary to do a good job of daily maintenance of the guide rail and linear axis, and regular dust removal and cleaning. After cleaning the dust, grease the rack and lubricate the guide rail with lubricating oil. Each bearing should also be oiled regularly, so as to maintain flexible driving, precise machining and prolong the service life of the machine tool.

Fourthly, maintenance of cooling system of laser cutter

Need to replace the water in the cold water cabinet regularly. Generally, it needs to replace once a week. The quality and temperature of the circulating water directly affect the service life of the laser tube. Generally, manufacturers will require customers to use pure or distilled water, and the water temperature must below 35 degrees. If you do not change the water for a long time, it is easy to form scale, which will cause the pipeline to block, so you must change the water regularly.

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℃ water temperature is better); when the water is cut off, the tube end will burst due to the heat 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 bend (dead bend) or falls off, and the water pump fails, it must be repaired in time to avoid power drop or even equipment damage.

Fifthly, working environment requirements of laser cutter

The production workshop where the equipment is placed should be dry and well ventilated. The indoor temperature should preferably be between 4-33°C.  Also should prevent the equipment from condensation in summer and anti-freezing measures should be taken in winter. The equipment should be placed far away from places with electromagnetic interference, away from places with large electricity and strong earthquakes.

The interference of large electricity will cause the equipment to malfunction from time to time. Although it is not inevitable, also must prevent it. Therefore, the equipment should not be placed with large electric welding. Nearby equipment, such as machines, giant electric mixers, etc. Not to mention strong vibrations, ground vibrations will obviously cause deviations in the accuracy of laser engraving.

Sixthly, some other matters needing attention of laser cutter

During the operation of the equipment, the operator should always observe the operation of the equipment. If an abnormality occurs, immediately stop the operation of the equipment, cut off the power supply. And promptly report to a professional to inspect and repair the equipment. Do not disassemble and repair the equipment without permission. Perform regular statistics on the use of the equipment, and if there is an effect deviation, it should replace in time to prevent it before it happens. If you don’t know whether produced the material, do not process it, so as to avoid potential dangers and damage the laser equipment.
