1. Excellent beam quality: This series of fiber laser marking machines are much better than the traditional marking machine, condensation diameter is less than 20um, divergence angle is 1/4 of the semiconductor pumping source laser, used in accurate marking. 2. Low use-cost: high turnover ratio between electricity and laser, the whole machine power consumption is less than 500W, which is 1/10 of light pumping source laser. 3. Fast marking speed, 2-3 times faster than the traditional marking machine. 4. Long working life: using fiber laser as pumping source, working hours can reach as long as 100,000 hours. 5. Rotary worktable system is optional, thus, accomplish marking on cambered surface. 6. Air-cooling, no water chiller needed like YAG laser marker, easy transportation.
