The maintenance and care of a laser cutting machine requires periodic operations focusing on its core components (cooling system, dust removal system, optical path system, transmission system, etc.). Considering the current summer environmental conditions, specific maintenance points are as follows:

I. Cooling System Maintenance (Key to Extending Laser Tube Life)

Circulating Water Management: It is recommended to change the circulating water monthly (using purified or distilled water) to prevent scale buildup and blockage of the water channels. In summer, the water temperature should be controlled between 27℃ and 28℃ (not lower than the dew point temperature inside the laser). If it exceeds 38℃, the water should be changed immediately or the temperature lowered (e.g., by adding ice).

Water Flow Check: Before starting the machine daily, check that the cooling water is flowing smoothly, avoiding sharp bends (dead bends) or detachment of water pipes to prevent laser tube bursting or power reduction due to water interruption.

II. Dust Removal System (Fan) Maintenance (Ensuring Smoke Exhaust Effectiveness)

Cleaning Cycle: Clean approximately every three months. If insufficient suction or poor smoke exhaust is detected, turn off the power, disassemble the fan's inlet and outlet pipes, remove internal dust, reverse the fan to clean the blades, and test suction after reinstallation.

III. Optical Path System (Lens) Maintenance (Ensuring Beam Quality)

Daily Cleaning: Before daily work, check the reflectors (3 pieces) and focusing lens (1 piece). Wipe them from the center to the edge with ethanol-soaked cotton (handle gently to avoid damaging the surface coating); the focusing lens must be installed with the concave side facing down. Regular Inspection: Check the lens for contamination at least once a month and clean it promptly to avoid laser loss or lens damage.

IV. Transmission System Maintenance (Ensuring Operating Accuracy)

Guide Rail Cleaning and Lubrication: Clean the guide rails every two weeks (power off) to remove corrosive dust and smoke residue; lubricate the X/Y/Z axis guide rails and lead screws monthly (use grease for the Z-axis) to reduce wear.

Screw and Coupling Tightening: Monthly inspection of screws and couplings at moving parts. Tighten any loose screws or abnormal noises promptly to ensure smooth mechanical movement.

V. In-Depth Maintenance at Different Cycles

Weekly: Inspect the laser gas mixing unit (clean oil/water), cooler filter (clean exhaust screen and internal screen), and compressed air separator (drain condensate). Semi-annually (or after 2000 hours of operation): Inspect the laser head cooling water pipes for corrosion and the excitation power supply oil tank for leaks; clean the internal lenses of the laser resonator and adjust the light output mode.

VI. Operation and Environmental Precautions (Extending Equipment Lifespan)

Environmental Control: Maintain the workshop temperature between 15℃ and 30℃ in summer (to prevent condensation inside the laser) and reduce dust and smoke accumulation;

Standard Operation: Always disconnect the power during maintenance to avoid accidental operation; adjust power, speed, and other parameters according to the material during cutting to avoid overloading;

Replacement of Wear Parts: Inspect lenses and nozzles every 3-6 months and replace them promptly if worn; the laser tube has a lifespan of approximately 1-2 years (replace when power decreases or the beam becomes unstable), and original factory parts should be preferred. By implementing the above maintenance measures, the lifespan of the laser cutting machine can be effectively extended, ensuring cutting accuracy and stability.
