Laser cutting machine is a kind of equipment that uses laser beam to achieve material cutting. It has the advantages of precision, efficiency and flexibility, and has been widely used in industrial manufacturing, architectural decoration and other fields. However, laser cutting machine in the use of the process will also appear some common problems, the following will introduce some common problems and solutions.
First, the beam quality problem
1. Beam deflection: When the laser cutting machine beam deflection is found, you can first check whether the light path is normal, such as whether the beam is orthogonal to the light source. If the light source is orthogonal to the beam, the optical instrument can be used to adjust the light path so that the beam remains straight.
2. Beam distortion: laser cutting machine beam distortion problem may be due to the lens is not clean or lens misalignment caused. The solution is to clean the lens regularly and adjust the light path using optical instruments.
Two, cutting quality problems
1. Uneven cutting surface: If the cutting surface is uneven, it may be caused by tool wear or inappropriate tool material selection. The solution is to replace the tool or adjust the tool material in time.
2. The cutting surface has burrs: When the cutting surface is found to have burrs, it may be caused by unstable laser power or too fast cutting speed. The laser power or cutting speed can be adjusted to ensure smooth cutting surface.
Three, cooling system problems
1. The water temperature is too high: the laser cutting machine needs to reduce the temperature of the light source through the water cooling system to ensure the normal operation of the equipment. If the water temperature is found to be too high, you can check the working status of the water cooling system, such as whether the pump is running normally, and whether the water pipe is smooth. At the same time, the heat dissipation of the water cooling system can be increased to ensure the normal use of the equipment.
2. The water pressure is too low: When the water pressure is too low, the laser cutting machine may not work properly, which may be caused by water pipe blockage or water pump failure. The solution is to check whether the water pipe is blocked, if there is a blockage, you need to clean the water pipe; If the pump is faulty, replace the pump.
Four, gas system problems
1. Unstable gas pressure: Unstable gas pressure may lead to uneven cutting, unclear cutting gap and other problems. The solution is to adjust the gas pressure and keep it stable. At the same time, clean the gas system regularly to prevent clogging.
2. Too large or too small gas flow: too large gas flow may lead to overheating of cutting, and too small gas flow may lead to a decline in cutting quality. The solution is to adjust the gas flow to maintain the appropriate cutting effect.
5. Security issues
1. Laser radiation: Laser radiation generated by laser cutting machine has certain harm to the human body. When using the laser cutting machine, you need to wear protective glasses and ensure that there is no personnel in the working area of the laser cutting machine to avoid danger.
2. Gas leakage: Gas leakage may cause safety accidents such as fire or explosion. When using a laser cutting machine, it is necessary to regularly check the tightness of the gas system to ensure that the gas does not leak.
Summary: Although laser cutting machine has a wide range of applications in industrial production, there are still some common problems. By understanding and solving these problems, the normal operation of the laser cutting machine can be guaranteed and the cutting quality and safety can be improved. At the same time, regular maintenance and maintenance of the laser cutting machine can extend the service life of the equipment and improve production efficiency.
