PR-L Heavy-Duty Large Format Fiber Laser Cutter
The PR-L series is a true industrial powerhouse designed for ultra-large format and ultra-high power thick plate cutting. Featuring a heavy-load stress-relieved bed and a long-span gantry frame, it processes full-size large sheets in a single setup. Perfect for thick carbon steel, stainless steel, and alloy plates in heavy industries.
Key Engineering Advantages
- Ultra-Heavy Bed: Stress-relieved heavy-load structure minimizes deformation when cutting thick plates continuously.
- Large Format: Extra-long worktable (up to 12m) allows for one-time forming of full sheets, eliminating re-clamping.
- Extreme Power Ready: Compatible with up to 60kW ultra-high power sources for stable thick plate piercing and excellent edge quality.
- Reinforced Gantry: Heavy-duty transmission system ensures stable high-speed running and reliable long-term precision.
- Smart Process Library: Built-in dedicated thick plate process library, fully supporting thick plate bevel cutting.
- Global Heavy Industry Ready: Supports OEM, neutral packing, and CE kits for demanding overseas heavy-industry buyers.
Built for Extreme Heavy-Duty Applications
🏗️ Ultra-Heavy Frame
The machine bed is a massive, stress-relieved steel structure. It absorbs vibrations and maintains absolute stability even during extreme 60kW thick plate piercing.
📏 Long-Span Gantry
Designed with a reinforced long-span gantry. The dual-drive servo motors are perfectly synchronized to prevent gantry skewing on ultra-wide sheets.
🔥 Thick Plate Piercing
Equipped with high-power-specific CNC software and advanced piercing routines, ensuring clean holes and smooth cuts without secondary polishing.

Frequently Asked Questions
What is the maximum working area available?
We offer standard sizes from 6025 up to ultra-large formats like 12025 (12 meters by 2.5 meters) for one-time full sheet processing, eliminating multiple re-clampings.
Does the bed deform when cutting thick plates?
No. The machine features an ultra-heavy stress-relieved bed and a long-span gantry structure designed to minimize deformation during continuous thick plate cutting.
Can it be equipped with a bevel cutting head?
Yes, we offer an optional high-power bevel cutting head, which is essential for preparing weld edges in shipbuilding and heavy steel structures.
