1. Why High-Power Fiber Laser Cutting Matters
一、为什么高功率光纤切割越来越重要？
In today’s metal fabrication market, customers care about more than laser power. They care about cutting speed, gas consumption, edge quality, stability, and return on investment.
在现在的钣金和金属加工市场，客户关注的不只是激光功率，而是切割速度、气体消耗、断面质量、稳定性和投资回报率。
A high-power laser is like a strong engine. But without the right cutting process, the machine cannot release its full value.
高功率激光器就像一台强劲发动机，但如果没有合适的切割工艺，设备价值很难真正释放出来。
