When the laser cutting machine is processed, the cutting surface will have some conditions, such as impenetrable cutting, rough cutting surface is not smooth, hanging slag, wavy or vibration marks, over-burning or heat-affected area is too large, diagonal stripes or uneven cutting, burr and so on. Once these problems occur, the operator needs to come up with solutions in time to avoid waste of materials caused by more workpiece waste.

Laser cutting machine cutting surface is not smooth may be caused by a variety of factors, the following are some common reasons and corresponding adjustment suggestions:

1. Poor laser beam focusing: the laser beam is not correctly focused on the material will also lead to a reduction in cutting quality. Check and adjust the focal length of the laser head to ensure accurate laser focus.

2. Improper setting of cutting parameters: unreasonable setting of laser power, cutting speed, focal length and other parameters may lead to rough cutting surface. Too high or too low laser power will affect the cutting quality, too high may cause the material to overheat, melt or burn, too low may cut incomplete. Should be adjusted to the appropriate range according to material type and thickness.

3. Auxiliary gas problem: the auxiliary gas (such as oxygen, nitrogen) used in laser cutting is not pure enough or the flow rate is set improperly, which will affect the removal of slag in the cutting process, resulting in rough cutting surface. The gas supply system should be checked and the gas type and flow rate adjusted.

4. Material selection and setting do not match: different materials have different adaptability to laser cutting, and corresponding parameter Settings are required. If the parameters are not optimized for a particular material, poor cutting quality may result.

5. Machine software and firmware: laser cutting machine control software and firmware problems may also lead to inaccurate cutting. Check and update to the latest version to ensure that algorithms and control signals are accurate.

6. Mechanical and optical parts status: laser cutting machine optical lens, cutting head or moving parts if there is dirt, wear or calibration inaccurate, will directly affect the quality of cutting. Regular cleaning and maintenance is necessary.

7. Working environment factors: dust, temperature and humidity in the working environment may also affect the cutting quality. Keep the environment clean and control the appropriate temperature and humidity conditions.
