How to solve the abnormal alarm of laser cutting head?
The laser cutting machine is a high-precision processing equipment, but various faults may occur during use. Among them, the abnormal alarm of laser cutting head is a common fault phenomenon. So, how to solve the abnormal alarm of laser cutting head? Let's introduce it in detail below.
1. Causes of abnormal alarm
When using the laser cutting machine, if the cutting head abnormal alarm occurs, it is likely caused by the following reasons:
1. The optical lens is dirty or broken;
2. The optical path is abnormal;
3. The laser power is insufficient or too large;
4. The distance between the laser cutting head and the workpiece is incorrect;
5. The gas flow is insufficient or too large;
6. The surface of the workpiece is uneven or the height is inconsistent.
2. Solutions to common alarms
For different reasons for abnormal alarms of laser cutting heads, we can take the following methods to solve them:
1. Clean the optical lens: First, you need to turn off the power of the laser cutting machine, and then gently wipe the optical lens with alcohol or detergent to ensure that its surface is clean and dust-free. If the lens is broken, you need to replace it with a new optical lens.
2. Check the optical path: Check whether the optical path is normal and whether there are loose or damaged parts. If there are, they need to be replaced or repaired.
3. Adjust the laser power: When the cutting head alarms abnormally, you can try to adjust the laser power. Generally, too much or too little power will cause abnormal alarms.
4. Adjust the distance between the cutting head and the workpiece: It is necessary to adjust the distance between the laser cutting head and the workpiece according to the different materials and thicknesses of the workpiece to ensure the appropriate distance.
5. Adjust the gas flow: According to the different materials and thicknesses of the workpiece, adjust the gas flow to ensure that the gas flow is moderate, which can protect the optical lens and ensure the cutting effect.
6. Flatten the workpiece surface: If the workpiece surface is uneven or the height is inconsistent, it needs to be processed or trimmed to ensure the surface is flat.
3. Precautions
1. Before any maintenance or replacement work, you need to turn off the power of the laser cutting machine and wait for it to stop running completely.
2. When cleaning the optical lens, you need to use a special cleaner or alcohol, and you must not use corrosive or harmful substances.
3. When adjusting the laser power, it is necessary to adjust it step by step according to the actual situation, and it should not be adjusted too much or too little at one time.
4. When adjusting the distance between the cutting head and the workpiece, it is necessary to adjust it step by step according to the actual situation, and it should not be adjusted too much or too little at one time.
5. When using the laser cutting machine, it is necessary to regularly maintain and service the equipment, and pay attention to operating specifications and safety.
In summary, the solution to the abnormal alarm of the laser cutting head needs to be investigated and solved according to the specific situation. When using the laser cutting machine, it is necessary to pay attention to the maintenance and service of the equipment, and follow the operating specifications and safety requirements to avoid the occurrence of faults. 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 and processing effect of the equipment.
