How To Solve The Abnormal Alarm Of Laser Cutting Head?
Laser cutting machine is a kind of high-precision processing equipment, but in the use of the process may appear a variety of faults. Among them, the laser cutting head abnormal alarm is a relatively common failure phenomenon. So, how to solve the laser cutting head abnormal alarm? We will introduce it in detail below.
●The reason for abnormal alarm
In the use of laser cutting machine, if the cutting head abnormal alarm, it is likely to be caused by the following reasons:
1. The optical lens is defaced or broken;
2. The optical path is not normal;
3. Insufficient or excessive laser power;
4. Incorrect distance between the laser cutting head and the workpiece;
5. Insufficient or excessive gas flow;
6. The surface of the workpiece is not flat or the height is not consistent.
●Solution for abnormal cutting head alarm
For different reasons of abnormal alarm of laser cutting head, we can take the following methods to solve:
1. Clean the optical lens: first of all, you need to turn off the laser cutting machine power supply, and then gently wipe the optical lens with alcohol or detergent to ensure that its surface is clean and dust-free. If the lens has been broken, you need to replace the new optical lens.
2. Check the optical path: check whether the optical path is normal, whether there are loose or damaged parts. If there are, they need to be replaced or repaired.
3. Adjust the laser power: in the cutting head abnormal alarm, you can try to adjust the laser power size, in general, the power is too large or too small will lead to abnormal alarm.
4. Adjust the distance between the cutting head and the workpiece: according to the different materials and thickness of the workpiece, you need to adjust the distance between the laser cutting head and the workpiece to ensure that the distance is appropriate.
5. Adjust the gas flow: according to the different materials and thickness of the workpiece, adjust the gas flow to ensure that the gas flow is moderate, both to protect the optical lens, but also to ensure the cutting effect.
6. Flatten the surface of the workpiece: If the surface of the workpiece is uneven or inconsistent in height, it needs to be processed or trimmed to ensure that the surface is flat.
●Precautions
1. Before carrying out any repair or replacement work, you need to turn off the power of the laser cutting machine and wait for it to stop running completely.
2. In the optical lens cleaning, you need to use a special cleaner or alcohol, do not use corrosive or harmful substances.
3. In the laser power adjustment, you need to adjust gradually according to the actual situation, not a one-time too big or too small adjustment.
4. When adjusting the distance between the cutting head and the workpiece, it is necessary to adjust gradually according to the actual situation, and shall not be adjusted too large or too small at once.
5. In the use of laser cutting machine, the need for regular maintenance and maintenance of equipment, pay attention to operating standards and safety.
In summary, the solution to the abnormal alarm of the laser cutting head needs to be determined according to the specific situation. When using the laser cutting machine, you need to pay attention to the maintenance and repair of the equipment, and follow the operating norms and safety requirements to avoid the occurrence of failures. If the abnormal alarm problem cannot be solved, it is recommended to contact the manufacturer or professional maintenance personnel in time to ensure the normal operation of the equipment and processing results.
