Fiber laser cutting machine GIANT Series

large-formatgantry typehigh-precision

Overview
This dual-drive gantry fiber laser cutter integrates precision mechanical design with ytterbium-based fiber laser technology to deliver high electro-optical efficiency and stable 24/7 operation. The optimized drive structure balances inertia and torque for improved dynamic stability, while a modular semiconductor laser architecture supports redundant operation for continuous industrial production.

Key Features

• High-efficiency ytterbium fiber laser system with up to 35% electro-optical conversion for reduced operating costs and improved energy efficiency.
• Dual-drive gantry structure with high-torque precision reducers for accurate, stable motion control.
• Modular semiconductor and redundant fiber laser design enabling continuous 24-hour production.
• Design suited for large-format cutting with reduced downtime and strong adaptability to process changes.

Modular Cutting Platform

• Separate modular worktable and machine bed reduce thermal transfer from high-power cutting and minimize shocks and vibrations during loading/unloading.

Machine Bed

• High-rigidity, large-section steel bed with bent/inlaid/welded plates and internally welded ribs, optimized by finite element analysis (FEA) for structural stiffness.
• Manufacturing process includes annealing, rough machining, vibration aging and precision finishing to ensure long-term positional accuracy.

Machine Tool Protection

• Emergency stop buttons positioned on both sides of the crossbeam, mechanical travel switches at axis ends and buffer devices to ensure safe machine movement.

Extruded Aluminum Beams

• For formats under 4.5 m, FEA-optimized high-rigidity extruded beams with inner cavity stress dispersion reduce weight and improve dynamic performance.
• Adaptive telescopic connections between beam and pallet maintain cutting stability across varying operating conditions.

Automatic Backlash Compensation

• Integrated automatic anti-backlash mechanism on both sides of the X-axis slide ensures precise gear-rack engagement and maintains accuracy over long travel distances in large-format applications.
