Amid the global manufacturing industry's shift toward intelligence and sustainability, laser cutting machines, as core equipment for high-precision machining, rely heavily on the reliability of their cooling systems to ensure production efficiency and support the industry's low-carbon transition. Currently, the laser processing sector faces dual challenges: On one hand, high-end manufacturing fields such as aerospace and new energy vehicles demand stricter requirements for machining accuracy and continuous operation (e.g., machining tolerances must be controlled within ±0.01 mm), making cooling system performance a critical bottleneck. On the other hand, extreme operating environments (e.g., high-temperature workshops, dusty workshops) increase cooling system failure rates by 35% compared to standard conditions, resulting in annual downtime losses exceeding 1 million yuan. Traditional "post-failure repair" approaches no longer meet the industry's needs for quality and efficiency improvements. In this context, research on cooling system fault diagnosis and maintenance strategies holds significant industrial value. It can help enterprises reduce operational costs by 25%-30%, build reliability advantages in high-end manufacturing competition, and accelerate the transition to intelligent production models.
