Fiber laser cutting machine LN series

for metalfor thin sheet metalfor the automotive industry

Overview
The LN Series single-platform fiber laser cutting machine is engineered for precision cutting of thin to medium sheet metal. The machine uses dual-bus servo motors for improved dynamic response and achieves a dry running speed of 120 m/min with maximum acceleration of 1.5G. Its modular tabletop design facilitates transport and lowers maintenance logistics. The gantry is an aerospace-grade aluminum beam formed by 4300-ton press extrusion and aged to 6061 T6 for a high strength-to-weight ratio.

Key features

• Dual bus servo motor system — improves dynamic performance by ~30%
• Maximum acceleration: 1.5G
• Dry running speed: 120 m/min
• Modular tabletop for simplified transport and reduced maintenance costs
• Aerospace aluminum gantry (4300-ton press extrusion, aged to 6061 T6)
• Air pressure DA correction to accurately reach set outlet air pressure
• Automatic nozzle replacement for automated processing
• Intelligent Z‑axis vibration suppression to reduce cutting jitter
• Collision avoidance during movement to lower collision risk
