A Guide For Fiber Laser Cutting Machine Maintenance


The fiber laser cutting machine is the main cutting tool in sheet metal processing. Its application brings better cutting results. Regular maintenance is essential to ensure optimal performance and longevity. In addition, a good working environment and correct operating habits can also extend the service life of the equipment. However, users often ignore this problem. This can easily lead to a decrease in the cutting efficiency and shorten the use time. So, how do you do daily fiber laser cutting machine maintenance? Please read on to get more tips.

Fiber Laser Cutting Machine Maintenance

The following is laser cutting machine maintenance checklist. You can follow the tips below. Follow the manufacturer’s guidelines and seek professional help if needed.

1. Fiber Laser Cutting Equipment Machine Tools

  • Regularly clean the debris around the air outlet to ensure the ventilation effect.
  • Regularly check the filter in the air circuit and remove accumulated water and debris in the filter promptly.
  • Regularly check whether the travel switch bracket and impact block bracket screws are loose.
  • It is necessary to promptly clean the dust on the ventilation fan filter of the electric control cabinet to ensure good ventilation to facilitate heat dissipation of internal electrical components.
  • Clean the guide rails of the finishing bed in time to protect the debris in the leather cavity to avoid damage to the guide rails, thereby extending the service life of the guide rails.
  • After the machine tool is installed and used for some time, the level of the machine tool should be readjusted to ensure the cutting accuracy of the machine tool.
  • The X-axis guide rail and screw, Y-axis guide and screw, Z-axis guide and screw lubricant must be checked every other week to maintain the lubrication of all moving parts and extend the life of the X, Y, Z-axis guide rails and screws. service life.
  • Depending on the workshop environment, check the surface contamination of the reflector and focusing mirror from time to time (at least once a month), and clean the optical lenses promptly to ensure their service life.

2. Optical Lenses

The lenses of fiber laser cutting machines are consumables, especially optical lenses, including protective lenses, collimating lenses, focusing lenses, etc. Ensure the usual placement, inspection, and installation to prevent lens damage and contamination. During the laser cutting process, a large amount of gas and metal impurities will be released from the working surface, and these gases and spatter will cause damage to the lens. When contaminants land on the lens surface, they absorb the energy of the laser beam, creating a thermal lens effect.
The laser is reflected and focused by the lens and then emitted from the laser head. After the equipment has been running for a while, some dust will stick to the surface of the lens. This dust will have a great impact on the reflectivity and transmittance of the lens, resulting in a reduction in laser power. At this time, the lens needs to be cleaned. But you must be careful when cleaning. Lenses are fragile items. They should be handled with care, and do not touch the lenses with sharp objects or hard objects.

The steps and precautions for cleaning the lens are as follows:

First, use absorbent cotton dipped in ethanol and carefully wipe it, rotating from the center to the edge of the lens. The lens needs to be wiped gently without damaging the surface coating. During the wiping process, handle it with care to prevent falling. Please keep the concave side downward when installing the focusing mirror. In addition, try to reduce the number of ultra-high-speed perforations used daily. Using regular perforations can extend the service life of the focusing lens.

3. Cooling System

The water chiller needs regular maintenance, and the water in the water dispenser needs to be replaced regularly. The general replacement frequency is one month to ensure the good working condition of the machine. When it comes to water, try to choose distilled water. If there are no conditions, you can choose deionized water. Each manufacturer has requirements for water quality. Remember to meet the requirements. Otherwise, long-term use of substandard water will cause scale to accumulate inside the laser. If there is a fault, please ask professional technicians to repair it. Do not disassemble the machine by yourself.

4. Dust Removal System

The exhaust dust removal system is an auxiliary component of the fiber laser cutting machine. Its main function is to promptly and effectively remove the dust generated by laser cutting, protect important precision parts of the machine tool from dust contamination, and at the same time play a role in protecting the workshop environment. The maintenance of the exhaust dust removal system can be carried out according to the maintenance table of the exhaust fan, and each maintenance situation should be recorded in detail in the maintenance registration form.

5. Fiber Laser Metal Cutting Machine Transmission System

The transmission system of the fiber laser metal cutting machine is a key part to ensure the smooth and precise movement of the laser head. Regular maintenance is necessary to keep it in top condition and avoid any potential problems. Let me walk you through some key steps in maintaining your machine’s drivetrain.

  • First, make sure all moving parts are cleaned and lubricated regularly. The guide rails must be cleaned and lubricated frequently, and the motor must also be cleaned and lubricated frequently. The machine will be able to move better and cut more accurately during travel, and the quality of the cut products will be improved. This will help reduce friction and keep everything running smoothly.
  • Also, check for any loose or damaged components and replace them if necessary.
  • Finally, don’t forget to calibrate your system regularly to ensure accurate laser cutting.
  • The environment of the workshop should be kept dry and well-ventilated, with the ambient temperature between 4°C and 33°C. Pay attention to preventing condensation on the equipment in summer, and protect laser equipment from freezing in winter.
  • During the operation of the equipment, the operator must observe the working conditions of the equipment at any time. If any abnormality occurs, immediately cut off all power supplies, promptly troubleshoot or report to the supervisor, and actively take corresponding measures. Regularly count the usage of the machine, and regularly record each part of the laser cutting machine. If there is any poor performance, replace it in time to prevent problems before they occur.

Scientific and orderly fiber laser cutting machine maintenance can effectively avoid some minor problems in the use of laser cutting machines, effectively improve the performance and service life of some accessories, and virtually improve work efficiency.
