How to solve the problem of poor cutting quality during the use of a laser cutting machine?

I. Cutting Quality Issues

  1. Rough cutting surface/burrs

    • Cause Insufficient power, focal length offset, insufficient gas purity (e.g., unstable nitrogen/oxygen pressure).
    • Solution Adjust power/speed matching parameters, check lens contamination or nozzle damage.

  2. Burning/blackening of cutting edges (Metal materials)

    • Cause Insufficient auxiliary gas (e.g., nitrogen) pressure or flow mismatch.
    • Solution Replace high-purity gas (≥99.9%) and calibrate gas pressure (e.g., 15-20 Bar for stainless steel cutting).

  3. Incomplete cutting or perforation failure

    • Cause Material thickness exceeds equipment limits (e.g., 6kW cutting 20mm carbon steel is a reasonable threshold), or lens aging.

II. Equipment Operation Failures

  1. Laser alarm/shutdown

    • Common codes Overly high water temperature (cooling system blockage), power failure (unstable voltage).
    • Solution Regularly clean the cooling filter, install a voltage regulator.

  2. Abnormal noise from guide rails/gears

    • Cause Lack of lubrication or dust accumulation over time.
    • Maintenance Clean the guide rails with special grease monthly, avoiding metal debris residue.

  3. Optical path offset (Cutting shape distortion)

    • Calibration Use a red light positioning instrument to check the coaxiality of the reflecting mirror/focusing mirror.

III. Operation and Software Issues

  1. Graphic cutting misalignment

    • Possible causes Software parameters (such as DPI settings) do not match the machine, or the drive belt is loose.

  2. Control system freezes/crashes

    • Prevention Regularly clear system cache, avoid risks of pirated software cracking.

IV. Environmental and Consumable Issues

  1. Frequent damage to lenses/nozzles

    • Root cause Metal vapor back-splash (anti-splash spray can be added) or human collision.
    • Cost control Purchase coated lenses (lifespan extended by 3 times, but Price is 30% higher).

  2. Unstable power supply (Especially in laboratory/construction site scenarios)

    • Suggestion Equip with UPS or dedicated line to prevent voltage fluctuations from damaging the power module.

V. Safety Warnings

  • Dust explosion Aluminum/magnesium alloy cutting requires specialized dust removal equipment (spark ignition risk).
  • Laser radiation Operators must wear protective eyewear (special goggles are required for 1064nm fiber laser).

Quick Self-Inspection Process ：

  1. Check parameters → 2. Check gas/optical path → 3. Check consumables → 4. Measure voltage/cooling
    If the problem persists, contact the manufacturer for remote diagnosis or core component replacement (such as the laser module) as a priority.
