With its high efficiency, precision and flexibility, laser cutting machines are widely used in metal processing, electronic manufacturing, advertising decoration and other industries. However, in actual operation, some problems may be encountered, which affect the normal working efficiency and cutting quality of the laser cutting machine. Today we will introduce the common problems that may be encountered in the process of using laser cutting machines and their solutions to help users better maintain and operate the equipment.
1. Cutting quality issues：
Problem description: Burrs, deformation, melting, and non-smooth cutting surface appear on the cutting edge.
Solution：
Adjust the focal length: The focus position has a direct impact on the cutting quality, and the focal length needs to be adjusted according to the thickness and type of material.
Check the nozzle and lens: Blockage of the nozzle or defacement of the lens will affect the quality of the laser beam. Regular cleaning and replacement are necessary.
Cutting parameters: Set the appropriate power, speed and pressure parameters according to different materials to avoid setting too large or too small parameters.
Use auxiliary gases: Selecting appropriate auxiliary gases (such as oxygen and nitrogen) can improve the cutting quality and speed.
2. Insufficient laser power：
Problem description: The laser output power is insufficient, resulting in impenetrable cutting or slow cutting speed.
Solution：
Check the laser: The performance and life of the laser will gradually decrease with the use time, and regular maintenance and calibration are required.
Cooling system inspection: The temperature of the cooling water is too high or too low will affect the laser power. It is necessary to keep the cooling water clean and at the appropriate temperature.
Optical path alignment: Deviation from the optical path of the laser beam will cause power loss, and the optical path system needs to be calibrated regularly.
3. Equipment alarm and failure：
Problem description: The equipment suddenly alarms or automatically shuts down during work.
Solution：
Check the electrical system: Loose wiring or component failure in the electrical system may cause the equipment to alarm, and it needs to be checked and fastened one by one.
Regular maintenance: Regularly inspect and maintain all components of the equipment, including lasers, cooling systems, optical path systems and transmission systems, to prevent failures.
Software upgrade: Update the control software in a timely manner, fix known vulnerabilities and improve stability.
4. Material adaptability issues：
Problem description: The cutting effect of different materials varies greatly, and some materials are difficult to be cut or have poor cutting effect.
Solution：
Material selection: Choose materials suitable for laser cutting and avoid materials that contain highly reflective or volatile components.
Parameter adjustment: For different materials, adjust the appropriate laser power, cutting speed and auxiliary gas.
Pretreatment materials: For materials with thicker surface coating or oxide layer, surface treatment can be carried out first to improve the cutting effect.
5. Insufficient operator skills：
Problem description: The operator is not familiar with the equipment, which leads to low cutting efficiency or frequent failures.
Solution：
Training and assessment: Organize equipment operation training regularly to improve the skill level of operators.
Write operation manuals: Provide detailed operation manuals and troubleshooting guides to help operators quickly solve common problems.
Experience sharing: Encourage the exchange of experience between operators to jointly improve the level of operation.
Laser cutting machines play an important role in modern industry, but they will inevitably encounter various problems in the process of use. By understanding and mastering these common problems and their solutions, users can better maintain equipment, improve production efficiency and cutting quality. I hope this article can provide a valuable reference for the majority of laser cutting machine users. Although the laser cutting machine is complicated, as long as it masters the correct operation and maintenance methods, it can exert its relatively high efficiency and become a right-hand man in production.
