Avoid Thermal‑deformation: Maintain Consistent Accuracy for Large‑format Heavy‑plate Laser Cutting

For metal fabricators of steel‑structure and engineering machinery, long‑time high‑power thick‑plate cutting brings a common pain point: bed thermal‑deformation. Hours of non‑stop thick‑plate cutting spreads heat to machine bed and linear guides, resulting in dimensional drift, burr parts and high re‑work rate, limiting plant output.

Conventional gantry machines connect cutting zone and transmission parts together. Cutting heat transfers directly to machine frame and causes obvious accuracy loss after long production shifts.

Foster 13035 ground‑rail gantry fiber laser cutter applies heat‑isolated worktable design, physically separating cutting zone and transmission system to block heat conduction. Single‑tube welded heavy‑duty bed with inner stiffeners undergoes full stress‑relief process to deliver superior rigidity for large‑format heavy‑plate processing.

Even under full‑power continuous daily operation from 3 kW‑40 kW, it keeps positioning accuracy ±0.05 mm and repeat‑positioning accuracy ±0.03 mm. Original Bochu bus CNC and smart laser head support anti‑collision and capacitive height‑tracking. Optional ±45° bevel cutting head realizes one‑pass bevel cutting without secondary finishing.

Equipped with intelligent dynamic dust‑removal system and safety light curtains to improve workshop environment and operator safety. Suitable for carbon steel, stainless steel, aluminum and alloy plates. Less re‑work means less material waste and faster order fulfillment.
