Commissioning Tips For 10kw+ Fiber Laser Cutting Machine

“10,000 watts” has been a highly sought-after topic in the laser industry in the past two years.

Currently, the 10,000 watt laser has been increasingly recognized and accepted by the market.

During this time, we have received feedback from some users regarding challenges they faced during the commissioning of the 10,000 watt laser cutting process.

To address these difficulties, we have compiled a list of common problems and provided corresponding solutions for your reference.

Commissioning method of cutting process of thick carbon steel plate

  • To debug the cutting process of carbon steel with fiber laser cutting machines that have a power over 10,000 watts, start by referring to the cutting process parameter table to achieve a bright surface on the thickest carbon steel and stabilize the cutting process for the thickest carbon steel.
  • After adjusting the perforation process parameters, ensure that the cutting efficiency and quality meet your requirements.
  • After adjusting the cutting and perforation process, carry out a small batch cutting to verify the consistency of the process and its effect.

Cutting nozzle heating1. Increase nozzle size
2. Clean the lens if the lens is dirty
3. Lower the cutting focus
Rough cutting surface1. Raise the cutting focus
2. Reduce nozzle size
3. Reduce cutting gas
4. Increase cutting speed
Cutting slag hanging1. Improper cutting speed
2. Increase the cutting air pressure
3. Improper cutting focus
Inconsistent cutting surface1. The nozzle outlet is not round
2. The laser is not in the center of the nozzle

Commissioning method of cutting process of thick stainless steel plate

  • For lasers with a power over 10,000 watts, refer to the laser cutting process parameter table and start by debugging the cutting effect on stainless steel with varying thicknesses.
  • After adjusting the perforation process parameters, ensure that the cutting efficiency and quality meet your requirements.
  • After adjusting the cutting and perforation process, carry out small batch cutting to verify the consistency of the process and its effect.

2. Increase the cutting air pressure
3. Reduce the negative focus
Slow efficiency1. Dirty lens
2. Increase the cutting air pressure
40mm: small amount of slag hangingCutting layered1. Reduce frequency
2. Raise the positive focus
3. Increase the cutting pressure
Yellow cutting surface1. Reduce the duty cycle
2. Raise the positive focus
3. Increase the cutting air pressure

Test method for cutting stability

To ensure the stability of the equipment during mass production and maintain consistent product quality, stability tests should be conducted prior to formal batch processing.

Testing material6-10mm stainless steelTest graphicsHelical line
Testing time5-10minTest gasNitrogen
Testing method1. Adjust the stainless steel cutting parameters to ensure that the cutting surface is free of slag and stratification
2. Cut continuously at full power for 5-10min to check whether the cutting surface is consistent;
3. In case of increasing slag hanging, blue light after cutting for a period of time, continuous cutting and other problems, it indicates that the cutting focus is offset. It is necessary to check the cutting head lens (dirty lens, poor lens quality, thermal lens problem) and the focus position.
Don't forget, sharing is caring! : )
