I. Maintenance and Upkeep
(1) Daily Maintenance
- Cleaning:
- After each use, clean the equipment’s worktable and the machine body to remove dust and debris. Clean the accumulated burnt residues on the laser head.
- Regularly clean optical components, such as mirrors and lenses, to prevent dust, oil, and other contaminants from affecting the transmission and focusing of the laser.
- Equipment Status Check:
- Before starting work, inspect the equipment’s appearance to ensure there are no abnormal conditions.
- Check whether the power supply line, air source line, and other connections of the equipment are secure.
- Examine if there are any loose, worn, or damaged parts on the equipment.
- Check if the buttons for the X-axis zero point, Y-axis zero point, Z-axis zero point, and laser readiness are damaged.
- Cooling System Check:
- Check the water level in the cooling tank and regularly replace the cooling water to ensure it is clean.
- Clean the filters and heat sinks of the cooling system to prevent blockages that could affect cooling performance.
- Light Path Check:
- Before starting the machine each day, observe whether the focusing lens of the laser machine is contaminated and clean it if necessary.
- Motion System Check:
- Inspect the mechanical moving parts of the equipment, such as guides, screws, and sliders, and apply lubricating oil or grease to ensure smooth movement.
- Check the tension of belts and chains, and adjust or replace worn parts in a timely manner.
- Electrical System Check:
- Check whether the electrical connection lines are loose and clean the dust on electrical components.
- Regularly inspect the working condition of the power supply, controller, and other electrical equipment to ensure they are functioning properly.
(2) Periodic Maintenance
- Weekly Maintenance:
- Conduct a comprehensive cleaning of the equipment, including the exterior, laser light path, cooling system, and control system.
- Check whether the energy of the laser beam is stable. If there are fluctuations, adjust it in a timely manner.
- Check if the water quality of the cooling system meets the requirements. If not, replace the cooling liquid promptly.
- Monthly Maintenance:
- Perform a deep cleaning of the equipment’s optical mirrors using specialized mirror cleaning solution and ultrasonic cleaner.
- Check whether the focusing accuracy of the laser beam meets the requirements. If there are deviations, adjust it in a timely manner.
- Check if the water pump of the cooling system is working properly. If there are faults, repair or replace it in a timely manner.
- Check the gas mixing unit of the laser for oil or water. If present, clean it promptly.
- Check the gas dryer filter of the laser. If more than 1/4 of the color turns red or white, replace it in a timely manner. The normal color is blue.
- Quarterly Maintenance:
- Lubricate the mechanical components of the equipment, including guides, screws, and motors.
- Check whether the output power of the laser beam meets the requirements. If there is a decrease, adjust it in a timely manner.
- Check if the filter of the cooling system is blocked. If so, clean or replace it in a timely manner.
- Annual Maintenance:
- Conduct a comprehensive inspection and repair of the equipment, including mechanical components, electrical components, and optical components.
- Perform maintenance and upkeep on the laser source of the equipment, such as replacing the laser tube and adjusting the light path.
- Conduct a comprehensive cleaning and maintenance of the cooling system, replacing the cooling liquid and filter.
- Upgrade and maintain the control system of the equipment to ensure its performance and stability.
II. Maintenance Precautions
- Before carrying out maintenance and upkeep, the power supply of the equipment must be turned off, and the equipment must be allowed to cool down before proceeding with the operation.
- When checking and cleaning the laser light path, protective glasses must be worn to prevent laser damage to the eyes.
- When maintaining the cooling system, the pressure in the cooling system must be released first to prevent the cooling liquid from spraying out and causing injury.
- When repairing the equipment, the operation must be carried out by professional technicians to prevent equipment damage or personal injury due to improper operation.

(2) Spare Parts Management Suggestions
- Establish Spare Parts Archives:
- Create a “health record” for each critical component, such as laser tubes and mirrors, to record the installation date and usage duration. This helps in planning replacements in advance.
- Choose Suitable Spare Parts:
- Prioritize certified consumables and spare parts from the original manufacturer. Avoid using substandard alternatives to
ensure the equipment’s performance and longevity.
- Reasonably Stock Spare Parts:
- Based on the equipment’s usage frequency and component wear, maintain a reasonable stock of commonly used spare parts, such as laser tubes, focusing mirrors, and nozzles, to minimize equipment downtime.
- Properly Store Spare Parts:
- Regularly clean and maintain stored spare parts to prevent damage or aging. For components that require special storage conditions, such as optical elements, store them in a dry, clean, and dust-free environment.
- Regularly Inspect Spare Parts:
- Periodically check the performance of spare parts in use. Replace any damaged or aged components promptly.
