How to diagnose and deal with abnormal noises when the laser cutting machine is running?

As an indispensable equipment in modern industry, the laser cutting machine is widely favored by the manufacturing industry for its efficient and precise cutting capabilities. However, in actual operation, the laser cutting machine sometimes has abnormal noises during operation, which not only affects the normal operation of the equipment, but also may have an adverse effect on production efficiency and product quality. This article will provide practical solutions for laser cutting machine users from the two aspects of diagnosis and treatment of abnormal noises.

1. Diagnosis of abnormal noises

The abnormal noises when the laser cutting machine is running may come from many aspects. The following are some common causes of abnormal noises and their diagnosis methods:

‌Mechanical component problems‌

‌Bearings and lubrication‌: After long-term use, the bearings may be worn or insufficiently lubricated, resulting in noise caused by metal friction. During diagnosis, the wear and lubrication status of the bearings can be checked, and the lubricant can be replaced or supplemented if necessary.

‌Gear transmission‌: Excessive gear transmission clearance or gear damage may cause noises of impact or abnormal meshing. At this time, the meshing condition and transmission clearance of the gears should be checked to ensure smooth gear transmission.

‌Drive belt‌: If the drive belt is loose or aged, it may slip or shake, causing abnormal noise. During diagnosis, the tightness and wear of the drive belt can be observed, and the aged or loose belt can be replaced in time.

‌Drive system failure‌

‌Motor problem‌: Damage to the motor bearing, internal jamming or winding problems may cause humming or abnormal vibration noise. During diagnosis, the operating status and bearing condition of the motor can be checked, and replacement or repair can be performed if necessary.

‌Linear guide and lead screw‌: Linear guides or lead screws that lack lubrication will make sharp friction sounds due to increased friction. At this time, the lubrication of the guides and lead screws should be checked, and lubricants should be added in time.

‌Abnormal load‌

‌Exceeding the load range‌: Plates that exceed the load range of the equipment may increase the mechanical burden and cause abnormal noise due to overload operation of the motor. During diagnosis, the load condition of the equipment should be checked to ensure that it operates within the rated load range.

‌Improper plate placement‌: Plates that are not placed correctly or have foreign objects stuck in them may cause shaking and impact sounds. At this time, check the placement of the plate and whether there are foreign objects inside the equipment.

‌Operation environment problems‌

‌Uneven ground‌: The laser cutting machine is installed on an uneven ground and is unstable, which may cause resonance and noise. During diagnosis, check the installation ground and fixation of the equipment to ensure smooth operation of the equipment.

‌Dust and debris‌: Dust, debris or foreign objects are stuck in the slide rails, transmission chains and other parts, which will affect the operation and make abnormal sounds. At this time, the dust and debris inside the equipment should be cleaned.

2. Treatment of abnormal noise

For the above-mentioned abnormal noise causes, the following treatment measures can be taken:

‌Strengthen equipment maintenance‌

Regularly inspect and maintain the mechanical parts of the laser cutting machine to ensure that the bearings, gears, transmission belts and other parts are in good condition.

Regularly lubricate the linear guides and lead screws to reduce friction and wear.

‌Optimize the transmission system‌

Regularly inspect and repair the motor to ensure that the motor runs smoothly and without abnormal noise.

Adjust the parameters of the transmission system, such as transmission clearance, belt tightness, etc., to ensure smooth and accurate transmission.

‌Reasonable load control‌

Select appropriate plates for cutting according to the rated load range of the equipment to avoid overload operation.

Ensure that the plates are placed correctly to avoid foreign objects getting stuck in the equipment and causing abnormal noise.

‌Improve the operating environment‌

Ensure that the laser cutting machine is installed on a flat and firmly fixed ground to avoid resonance and noise.

Regularly clean the dust and debris inside the equipment to keep the equipment clean and tidy.

‌Professional maintenance service‌

If the abnormal noise problem cannot be solved, you should contact professional maintenance service personnel for inspection and repair in time.

During the maintenance process, you should cooperate with the maintenance personnel to provide the use of the equipment and the fault phenomenon so as to quickly locate the problem and repair it.

3. Conclusion

The abnormal noise during the operation of the laser cutting machine is a complex problem, which may involve multiple factors. By strengthening equipment maintenance, optimizing the transmission system, reasonably controlling the load, improving the operating environment, and seeking professional maintenance services, the abnormal noise problem can be effectively solved to ensure the normal operation and production efficiency of the laser cutting machine. At the same time, users should also pay attention to the daily maintenance and maintenance of the equipment during use to extend the service life of the equipment and reduce maintenance costs.
