CNC fiber laser cutting machine maintenance is essential to ensure equipment performance, extend service life, and improve cutting quality. The following is a maintenance guide for fiber laser cutting machines, covering daily, regular, and long-term maintenance to help keep the equipment running efficiently and extend its service life.
Only when the lens is clean and the optical path is unobstructed can the laser beam output be stable.
Well-maintained guide rails and racks can maintain the accuracy of the cutting trajectory and avoid burrs and burnt edges.
A stable cooling system can prevent laser power fluctuations and improve cutting consistency.
Timely cleaning of dust and iron slag can prevent corrosion or jamming of components.
Reasonable lubrication can delay mechanical wear and avoid early failures.
Regularly check the status of the laser to extend the life of core components.
Daily maintenance can detect hidden dangers in advance and avoid sudden shutdowns.
Good maintenance can reduce the probability of damage to key components such as motherboards, power supplies, and lasers.
Small problems can be discovered and solved early to avoid major failures caused by delays.
Reasonable maintenance can reduce the frequency of replacing expensive components such as lenses, lasers, and water cooling systems.
Cleaning the electrical control cabinet and checking the cables can reduce safety risks such as electrical fires.
A normal exhaust system can prevent smoke and dust accumulation and ensure a healthy operating environment.
Stable and efficient equipment can ensure that orders are completed on time and enhance corporate reputation.
Reduce downtime and rework and improve overall production capacity.
Maintenance of a CNC fiber laser cutting machine is a key measure to ensure efficient, safe and stable operation of the equipment. The following is a comprehensive fiber laser cutting machine maintenance guide, covering daily and regular maintenance content and precautions, suitable for operators and maintenance personnel.
Clean the protective lens, focusing lens and collimating lens (if any) to avoid dust and oil.
Wipe gently with special lens paper and anhydrous alcohol.
Ensure the normal supply of auxiliary gas (such as nitrogen and oxygen).
Check whether the air pipe is leaking or broken.
Check whether the laser operation interface is abnormal (power, temperature, alarm).
Check whether the cooling water temperature is within the set range (such as 20℃±1℃).
Clean the residue and debris in the cutting area to prevent carbon deposition.
Wipe the guide rails and sliders and add lubricating oil (if it is not a linear motor structure).
Ensure smooth exhaust to prevent dust accumulation.
Check whether the fan or filter is blocked.
Clean the filter, check whether the coolant has deteriorated and whether the liquid level is normal.
If the water quality deteriorates, replace it with deionized water or pure water.
Check whether it is loose or hit; check whether the cable is worn.
Add lubricating oil to the screw, guide rail or gear rack.
Check whether the automatic lubrication system is operating normally (if any).
Focus system and Z-axis inspection
Check whether the Z-axis return to zero and the autofocus function are sensitive and accurate.
Check whether the sensor is faulty or contaminated.
Clean dust and keep good ventilation.
Check whether the fan, power supply, and terminal are loose or aging.
Export cutting process parameters, control system configuration, etc. to prevent loss.
Check whether the output power is attenuated.
Contact the manufacturer or professional maintenance personnel for comprehensive inspection and maintenance.
Use laser interferometer or alignment tool to check machine tool geometric accuracy and repeat positioning accuracy.
Adjust bolts, transmission parts, etc. when necessary.
- Replace water cooler filter elements, air filters, dust removal equipment filter elements, etc.
All maintenance work must be performed with power off.
Use specified types of lubricants and coolants.
Regularly train operators to avoid equipment damage caused by misoperation.
Contact the manufacturer regularly for annual inspections or remote diagnosis services.
- Regularly check whether the laser power is attenuated.
- Maintain stable ambient temperature and humidity to prevent condensation.
- Do not disassemble the light source module or circuit board without authorization.
- Frequently check whether the protective lens and focal lens are clean.
- Calibrate the autofocus system regularly.
- Ensure good air tightness to prevent the lens from being contaminated.
- Use water quality recommended by the manufacturer.
- Be careful to avoid condensed water dripping into electrical components.
- Maintain good ventilation and heat dissipation.
- Keep clean and lubricated to prevent metal powder or dust from entering.
- If abnormal noise or shaking occurs, it should be checked in time.
- Keep the electric cabinet dry and ventilated.
- It is strictly forbidden to rinse with water or wipe with a wet cloth.
- It is recommended to install a voltage stabilizer and lightning protection device.
- Only trained personnel are allowed to operate.
- It is strictly forbidden to open the protective cover or moving parts during operation.
- Update the operating system and software programs regularly.
- Record the time and content of each maintenance and establish a maintenance file.
- Enable the remote monitoring and diagnostic services provided by the manufacturer (if any).
Problems | Possible causes | Recommended treatment methods |
Poor cutting | Dirty lens, nozzle offset, insufficient air pressure | Clean, replace nozzles, check air source |
Power reduction | Laser attenuation, insufficient water cooling | Contact the manufacturer for calibration, replace water |
Abnormal alarm | System overheating, abnormal voltage, component failure | Check environment and power supply, and shut down for maintenance if necessary |
Deteriorated accuracy | Guide rails, rack wear, mechanical looseness | Adjust compensation or replace parts |
The importance of fiber laser cutting machine maintenance is reflected in many aspects such as stable operation of the equipment, extended service life, and ensuring cutting quality. The above is a detailed summary of fiber laser cutting machine maintenance. Reasonable maintenance is more economical and efficient than frequent repairs.
