Fiber Optic Laser Cutting Machine After-Sales Maintenance Service

Due to its high technicality and complexity, repair and maintenance services are very important to ensure the stable operation of the machine and extend its service life. This article introduces some key points of after-sales maintenance of fiber laser cutting machines.

After-Sales Service Quality

1. Timeliness of Response

It mainly depends on the response speed from reporting to repair. Generally speaking, the more grid-based layout of the station points, the faster the response speed and the stronger the response ability.

2. Timeliness of Problem Solving

It mainly depends on whether the fault can be quickly checked and solved.
The stronger the technical ability of the after-sales service team, the faster it can find the cause and provide solutions efficiently.

3. Economic Cost of Service

• Warranty Time

The longer the warranty time, the lower the economic cost.
But please note: the warranty time of the whole machine is not equal to the warranty time of the accessories.

• Service Costs Outside the Warranty Period

For services beyond the warranty period, the charging standards of different manufacturers are different. It is best to understand them clearly before sale.

• Replacement Cost of Spare Parts

If the spare parts are damaged beyond the warranty period and need to be replaced, the cost of spare parts and the allocation capabilities of different manufacturers need to be considered.

Maintenance Service

1. General Maintenance

Cleaning: Clean all parts of the machine regularly, including the laser head, guide rails, lenses, etc., to prevent dust and impurities from affecting the cutting quality and machine performance.
Lubrication: Regularly check and lubricate moving parts such as guide rails and gears to maintain their good motion performance.
Calibration: Regularly calibrate the laser generator and cutting head to ensure cutting accuracy.

2. Fault Diagnosis and Repair

Fault Detection: Use professional diagnostic tools to check the cause of system errors or performance degradation.
Part Replacement: Replace damaged or aged parts such as laser tubes, lenses, sensors, etc.
Software Upgrade: Update the machine's operating system and control software to improve efficiency and compatibility.

3. Technical Support

On-site Service: Provide on-site maintenance services, performed by professional technicians.
Remote Support: Provide technical support via telephone or the Internet to solve operational problems or minor faults.
Training Service: Provide training for operators, including daily maintenance, troubleshooting and safe operation of the machine.

4. Spare Parts Supply

Ensure quick access to original or compatible high-quality spare parts to reduce machine downtime.

5. Contract Maintenance Service

Provide regular maintenance service contracts, including preventive maintenance, regular inspections and priority response services, to help customers manage maintenance costs and ensure continuous operation of the machine.

6. Emergency Response

Provide rapid response services to deal with sudden machine downtime or serious failures to minimize production losses.

Common Problems and Solutions

1. Unstable or Inaccurate Pipe Cutting Length

Check whether the front baffle is loose or inaccurately positioned. If there is a problem, the front baffle should be fixed to ensure that it does not loosen. Check whether the conductive device is loose or has poor contact. If there is such a problem, the conductive device should be tightened and the contact copper sheet or spring should be clean and smooth.

2. Cutting Process is not Continuous

Check whether the rotation angle of the rotary chuck is less than 360 degrees during cutting. If so, the rotation angle parameter should be changed to 365-375 degrees. Check the pressure gauge to ensure that the air pressure is sufficient and there is no air leakage. Check whether the laser lens is dirty or the focus is improperly adjusted. If necessary, replace the lens and readjust the focus. Check whether the nozzle is blocked or damaged. If damaged, replace it in time.

3. There are too Many Burrs Inside and Outside the Cut Pipe

Check whether the copper nozzle is loose or stuck with iron slag, and ensure that the copper nozzle is tight and clean. Recalibrate the height adjuster and clamp the pipe first during calibration. Check whether the laser head protective lens is damaged or has black spots, replace it in time and ensure that the lens is clean. Check whether the focus is adjusted properly.

4. Deformation of Small Holes During Processing

If a lower-power laser cutting machine is used, a pulse perforation method should be used when processing small holes to obtain a better surface finish. For higher-power laser cutting machines, it may be necessary to change from a pulse perforation method to an explosive perforation method to reduce the burning phenomenon in non-processing areas.

5. Abnormal Sparks

Check whether the laser head nozzle is worn out. If necessary, replace the nozzle in time. Check whether the thread at the joint between the nozzle and the laser head is loose. If there is a problem, the operation should be stopped immediately and the thread should be tightened.

6. Lubrication and Maintenance Issues

Apply lubricant to the chuck regularly to ensure motion accuracy, but pay attention to correct lubrication operations to avoid adverse effects. Use specific grease for lubrication and adjust the lubrication frequency according to working conditions. Clean the dust and residue on the chuck and slide regularly to keep the surface clean.

7. Mechanical and Electrical Issues

Check whether there is too much dust on the guide rails of the laser tube cutting machine, clean the dust and add lubricating oil to the slider. Check whether the wires connecting the motor and the driver are in good contact, and make corresponding adjustments if necessary. Check whether the reset function is normal. If there is a problem, check the motherboard parameters, sensor and magnet position, etc.
