The importance and implementation guide of regular maintenance of laser cutting machines

In today's industrial manufacturing field, laser cutting machines have become indispensable processing equipment for many companies with their high precision and high efficiency. However, like any high-precision mechanical equipment, the performance and service life of laser cutting machines depend to a large extent on their maintenance and maintenance. This article will discuss in detail the importance of regular maintenance of laser cutting machines and provide a set of practical maintenance implementation guidelines to help companies better maintain and use laser cutting machines.

1. The importance of regular maintenance of laser cutting machines

‌Extend the service life of equipment‌

As a precision processing equipment, the internal components of the laser cutting machine, such as lenses and laser tubes, are easily damaged or aged after long-term use. Regular maintenance can detect and replace these damaged parts in time, thereby extending the overall service life of the equipment.

‌Maintain stable equipment performance‌

The performance of the laser cutting machine directly affects the precision and quality of the processed parts. Regular maintenance can ensure that the various performance indicators of the equipment are in the best condition and avoid processing quality problems caused by the decline of equipment performance.

‌Preventing Failures‌

Through regular inspection and maintenance, potential hidden dangers of failure can be discovered and eliminated in time, and sudden failures of equipment during processing can be avoided, which will affect production progress and efficiency.

‌Improve Equipment Safety‌

Laser cutting machines will generate high temperatures and laser radiation when working, which poses certain safety hazards. Regular maintenance can ensure that the safety protection devices of the equipment are intact and effective, and reduce the probability of safety accidents.

2. Implementation Guide for Regular Maintenance of Laser Cutting Machines

‌Daily Maintenance‌

‌Cleaning Optical Components‌: Before work every day, use anhydrous industrial alcohol or acetone to clean the reflector and focusing mirror to ensure that the mirror surface is free of dust or damage. At the same time, be careful to avoid direct contact with the lens with your hands to prevent scratches or corrosion.

‌Check the laser path‌: Before use every day, check whether the laser is emitted from the center of the nozzle. If it deviates, readjust the calibration.

‌Cutting Head Adjustment‌: Adjust the height of the cutting head to the appropriate drilling position before cutting to ensure cutting accuracy.

‌Workbench and connecting line inspection‌: Check and clean the workbench every day to keep it clean and tidy. At the same time, check whether the X, Y, and Z axes can return to the origin, whether the origin switch striker position is offset, whether the connection line is tightened and disconnected, and whether the control box fan is normal.

‌Cooling system maintenance‌ ‌Regularly replace the circulating water‌: Clean the chiller regularly and replace the internal circulating water. It is recommended to use distilled water without impurities (such as pure water or mineral water) and avoid tap water to prevent scale from blocking the waterway. The recommended replacement frequency is once a month.

‌Check the water temperature‌: Ensure that the temperature of the cooling water is controlled within an appropriate range to ensure the stable operation of the laser.

‌Dust removal system maintenance‌ ‌Clean the fan‌: Regularly clean the dust inside the fan to prevent increased noise and poor exhaust caused by dust accumulation. When the fan has insufficient suction and poor exhaust, it should be cleaned in time.

‌Optical path system maintenance‌ ‌Regularly check the lens‌: Regularly check the surface contamination of the reflector and focusing lens, and clean the optical lens in time to ensure its service life. When cleaning, pay attention to using the correct cleaning method and tools to avoid damaging the lens surface coating.

‌Transmission system maintenance‌

‌Lubrication and tightening‌: Regularly check and clean the guide rails, lead screws and other transmission parts of the X-axis, Y-axis and Z-axis, apply an appropriate amount of lubricating oil to keep them lubricated. At the same time, check and tighten each connection part to prevent looseness from affecting the accuracy of the equipment.

‌Electrical system maintenance‌

‌Regularly check the electrical cabinet‌: Ensure that the electrical cabinet and the wiring terminals are not loose or corroded, and keep the electrical system safe and reliable.

‌Environmental control‌

‌Keep the equipment working environment clean and tidy‌: The production workshop where the equipment is placed must be kept dry and well ventilated to avoid excessively high or low ambient temperatures. At the same time, regularly check and clean the filter at the air inlet to prevent blockage from affecting the cooling effect.

3. Conclusion

Regular maintenance of laser cutting machines is of great significance for extending the service life of equipment, maintaining stable equipment performance, preventing failures and improving equipment safety. By following the above maintenance implementation guidelines, enterprises can more effectively manage and maintain laser cutting machines, ensure their long-term stable operation, and provide strong guarantees for production. At the same time, this will also help enterprises maintain their leading position in the fierce market competition and achieve sustainable development.
