Mega4: Ultra-High Power 4-Chuck Heavy-Duty Laser Tube Cutting Machine
The Mega4 is Golden Laser’s flagship solution for the most demanding heavy-duty applications. Engineered specifically for ultra-long, large-diameter, and heavyweight profiles, the Mega4 utilizes a quad-chuck system to provide unrivaled stability and material utilization. With power options reaching 30kW, it is the industry standard for processing structural steel, oil pipelines, and heavy machinery components.


Key Technological Highlights
• Advanced 4-Chuck Synchronization: 
The pneumatic four-chuck system enables multi-point support and side-change cutting. This configuration achieves true zero-tailing waste and allows for the adjustment of clamping force based on material wall thickness to prevent deformation.
• 30kW Ultra-High Power: 
Designed for high-speed processing of thick-walled pipes, the Mega4 supports laser sources up to 30kW, significantly increasing throughput for heavy-industry materials.
• ±45 3D Swivel Head (Optional): 
The 3D laser head enables high-accuracy beveling and complex geometry cuts, reducing the need for secondary mechanical processing and ensuring superior weld preparation.
• Segmented Bed Architecture: 
A high-precision, three-section bed design ensures consistent axial alignment. The modular splicing mode simplifies logistics, allowing for easier transportation and rapid on-site installation.
• Massive Payload Handling: 
Capable of managing 12-meter raw materials with a total load capacity of 5 tons (bundle loading) and individual tube bearing of 100kg/m.
