Laser cutting machines represent a significant investment, ranging in price from hundreds of thousands to millions. Extending the machine's service life helps save on production costs and maximizes profitability; therefore, daily maintenance and care are crucial. The following outlines six key areas of maintenance:
1. Circulating Water Replacement and Water Tank Cleaning: Before operating the machine, ensure the laser tube is filled with circulating water. The quality and temperature of the water directly affect the laser tube's lifespan. Consequently, regularly replacing the water and cleaning the tank is essential-ideally on a weekly basis.
2. Fan Cleaning: Prolonged use causes significant dust accumulation inside the internal fans, leading to loud noise and impairing exhaust and odor removal capabilities. The fan must be cleaned whenever suction is insufficient or smoke extraction is obstructed.
3. Lens Cleaning: The machine is equipped with various mirrors and focusing lenses that reflect and focus the laser beam before it is emitted from the laser head. Lenses are prone to accumulating dust and other contaminants, which can cause laser power loss or lens damage. Therefore, daily cleaning is required.
Precautions during cleaning: 1. Wipe lenses gently to avoid damaging the surface coating. 2. Handle with care to prevent dropping. 3. When installing the focusing lens, ensure the concave side faces downward.
4. Guide Rail Cleaning: Guide rails and linear axes are core components responsible for guidance and support. High machining precision relies on the guide rails and linear axes maintaining excellent guiding accuracy and movement stability. During operation and processing, significant amounts of corrosive dust and smoke are generated. Long-term accumulation of these deposits on the guide rails and linear axes can severely impact machining precision, cause corrosion spots, and shorten the equipment's lifespan. Clean the guide rails every two weeks, ensuring the machine is powered off beforehand.
5. Tightening Screws and Couplings: After a period of operation, screws and couplings at motion joints may loosen, compromising the stability of the mechanical movement. Therefore, it is necessary to monitor the transmission components while the machine is in operation. If any issues-such as unusual noises or abnormalities-are detected, prompt reinforcement and maintenance are essential. Additionally, after the machine has been in use for a period of time, all screws should be tightened individually using the appropriate tools; the initial tightening should be performed approximately one month after the equipment is put into service.
