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.

 

1. The importance of fiber laser cutting machine maintenance

1) Ensure stable cutting quality

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.

 

2) Extend the service life of CNC fiber laser cutting machines

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.

 

3) Reduce failure rate and reduce downtime

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.

 

4) Save maintenance costs

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.

 

5) Ensure operational safety

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.

 

6) Improve production efficiency and delivery capabilities

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.

 

2. How to properly maintain a fiber laser cutting machine?

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.

 

- Daily maintenance (daily)

Check the laser head lens:

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.

 

Check the gas pipeline and air pressure:

Ensure the normal supply of auxiliary gas (such as nitrogen and oxygen).

Check whether the air pipe is leaking or broken.

 

Check the laser status:

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 bed and slide rails:

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).

 

Check the exhaust system:

Ensure smooth exhaust to prevent dust accumulation.

Check whether the fan or filter is blocked.

 

- Weekly maintenance

Check the water cooler:

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.

 

Inspect the structure of the laser head:

Check whether it is loose or hit; check whether the cable is worn.

 

Lubrication system maintenance:

Add lubricating oil to the screw, guide rail or gear rack.

Check whether the automatic lubrication system is operating normally (if any).

- Monthly maintenance:

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 the inside of the electric control cabinet:

Clean dust and keep good ventilation.

Check whether the fan, power supply, and terminal are loose or aging.

 

Software and parameter backup:

Export cutting process parameters, control system configuration, etc. to prevent loss.

 

- Quarterly or semi-annual maintenance

Complete inspection of the laser:

Check whether the output power is attenuated.

Contact the manufacturer or professional maintenance personnel for comprehensive inspection and maintenance.

 

Machine tool accuracy inspection and adjustment:

Use laser interferometer or alignment tool to check machine tool geometric accuracy and repeat positioning accuracy.

Adjust bolts, transmission parts, etc. when necessary.

 

Replace filter elements and consumables:

- Replace water cooler filter elements, air filters, dust removal equipment filter elements, etc.

 

- Notes

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.

 

3. Maintenance recommendations for key parts

1) Laser (core equipment)

- 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.

 

2) Cutting head

- 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.

 

3) Chiller

- Use water quality recommended by the manufacturer.

- Be careful to avoid condensed water dripping into electrical components.

- Maintain good ventilation and heat dissipation.

 

4) Guide screw and gear rack

- Keep clean and lubricated to prevent metal powder or dust from entering.

- If abnormal noise or shaking occurs, it should be checked in time.

 

5) Electric control system

- 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.

 

4. Safety and operation maintenance recommendations

- 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).

 

5. Prevention and treatment suggestions for common problems


Common problems and solutions table:
