I. Optical Path System Maintenance
Cleaning of Optical Components: Regularly inspect surfaces of reflectors, focusing lenses, and other components for dust, oil stains, or ablation marks. For contamination, use a specialized dust-free cloth and ethanol (purity ≥99.9%) to gently wipe in the same direction to avoid scratching the lenses. Replace damaged lenses or those with peeling coatings promptly.
Fiber Cable Inspection: Ensure the fiber has no bends (minimum bending radius usually ≥30cm), damage, or loose connectors. If transmission efficiency decreases (e.g., 明显 slower cutting speed), have professionals detect and replace the fiber.
II. Cooling System Maintenance
Water Quality and Level Management: Use deionized water or pure water (conductivity ≤5μS/cm). Check the water tank level weekly and add water if below the minimum mark. Replace all cooling water every 2-3 months to prevent scale buildup and pipe blockage.
Equipment Operation Status: Check if the water pump makes abnormal noises or if water flow is smooth (observe the flow indicator). Regularly remove dust from the compressor and condenser surfaces (blow with compressed air monthly) to ensure good heat dissipation and avoid shortening the laser's service life due to overheating.
III. Transmission System Maintenance
Lubrication and Wear Inspection:
Apply specialized lubricants (e.g., lithium-based grease) to components like guide rails, lead screws, and racks for each shift. If 卡顿 or abnormal noises occur during operation, check for foreign objects or wear.
Clean iron filings from gear transmissions regularly and apply gear oil. Inspect the tension of timing belts and replace them immediately if aged or cracked.
Accuracy Calibration: Use a laser interferometer to calibrate the equipment's positioning accuracy and repeat positioning accuracy annually (error usually ≤±0.05mm/m). If the deviation is too large, adjust the guide rail parallelism or replace worn components.
IV. Control System Maintenance
Data Backup and Software Update: Regularly (monthly) back up CNC system parameters, processing programs, and alarm records to prevent data loss from system failures. Stay updated with control software patches released by the manufacturer to optimize cutting algorithms and stability.
Anti-Interference Treatment: Equip the control system power supply with voltage stabilizers and filters to avoid electromagnetic interference (e.g., keep away from high-frequency equipment). Shield connection cables to prevent signal transmission anomalies.
V. Gas System Maintenance
Auxiliary Gas Management:
For metal cutting (e.g., oxygen, nitrogen), check if cylinder pressure is stable (typically oxygen ≥0.8MPa, nitrogen ≥1.0MPa). Ensure pressure reducers and pipeline joints have no leaks (detect with soapy water).
Replace gas filters quarterly to prevent oil, water vapor, and other impurities from entering the cutting head, which could affect cutting quality and lens life.
Cutting Head Protection: When cutting highly reflective materials (e.g., aluminum or copper plates), install specialized protective lenses or reduce power to prevent reflected light from damaging internal optical components. Inspect the cutting head nozzle for blockage or wear before each startup and replace it in a timely manner (typically recommended every 500 hours).
VI. Electrical System Maintenance
Circuit and Component Inspection: Every six months, check if wiring terminals in the distribution cabinet are loose and if cable insulation is aged. Replace contactors and relays immediately if their contacts are ablated. Secure encoder cables of motors to avoid damage from pulling during operation.
Grounding and Safety: Ensure the equipment's grounding resistance ≤4Ω, verify the effectiveness of leakage protection devices, and prevent electric shock risks. Test the functions of safety devices such as laser protective baffles and emergency stop buttons monthly.
