When using a laser cutting machine, common issues mainly focus on cutting quality, equipment operation, and material handling.

The following are the most common problems and solutions during the use of laser cutting machines organized by JINAN M-SHINE:

 The cutting edge is not smooth or has many burrs

Possible reasons:

-Insufficient or excessive laser power

-Cutting speed too fast/too slow

-Incorrect focal length (lens contamination or misalignment of focal length)

-Insufficient gas pressure (such as insufficient purity of nitrogen and oxygen)

-Impurities or uneven thickness on the surface of the material

resolvent:

-Adjust power and speed parameters (refer to material parameter table, gradually test).

-Clean or replace the lens, recalibrate the focal length.

-Check gas purity and pressure (such as high-purity nitrogen required for cutting stainless steel).

-Replace with high-quality materials to ensure a smooth surface.

The material cannot be cut through during cutting

Possible reasons:

-Power setting too low

-Cutting speed too fast

-Lens or nozzle contamination/damage

-Material thickness exceeds equipment capacity

resolvent:

-Reduce speed or increase power (note not to exceed the upper limit of the device).

-Clean or replace lenses and nozzles, and check if the optical path is offset.

-Confirm whether the material thickness matches the equipment power (e.g. 1000W CO ₂ laser usually cuts carbon steel ≤ 6mm)

Laser head collision or scratching of materials

Possible reasons:

-Platform unevenness or material warping

-Focal length sensor malfunction

-Manual height adjustment setting error

resolvent:

-Use a leveling machine or pad to ensure the material is flat.

-Calibrate or replace capacitive/mechanical sensors.

-Manually test the height before cutting and enable the "floating height adjustment" function.

 laser cutting machine Sudden stop/error during device operation

Possible reasons:

-Overheating trigger protection (water cooling system failure)

-Voltage instability or power outage

-Software crash or communication interruption

resolvent:

-Check whether the water temperature of the chiller (recommended 20-25 ℃) and the water pump are normal.

-Install voltage regulator and ensure good grounding.

-Restart the software and device, and check the data cable connection.

Deformation or inaccurate size of cutting graphics

Possible reasons:

-Transmission system issue (loose guide rail/belt)

-Software parameter compensation error

-Material thermal deformation

resolvent:

-Tighten the guide rail screws, lubricate the slider, and check the belt tension.

-Calibrate the "pulse equivalent" or "axis compensation" in the software.

-Optimize the cutting path to reduce local overheating (such as segmented cutting).

Frequent contamination or damage to lenses/nozzles

Possible reasons:

-Material coating or cutting residue rebounds

-Impurity of gas leads to oxidation

-Improper installation (excessive tightening or poor sealing)

resolvent:

-Use splash proof agents when cutting galvanized sheets and regularly clean the light path.

-Replace high-purity auxiliary gas (such as 99.9% or more nitrogen).

-Install the nozzle according to the manual torque to avoid collision.

 The laser cutter machine software cannot import files or freezes

Possible reasons:

-File format incompatibility (such as non DXF, AI formats)

-The graph has unclosed paths or redundant nodes

-Insufficient computer configuration

resolvent:

-Convert file formats and use CorelDRAW or AutoCAD to repair graphics.

-Remove duplicate lines to ensure the path is closed.

-Upgrade computer memory and close background programs.

Daily maintenance suggestions

1. Daily: Clean lenses, check gas pressure, and clean up waste materials.

2. Weekly: lubricate the guide rail, calibrate the optical path, and check the cooling system.

3. Monthly: Clean the fan ducts and check the stability of the circuit.
