SF6036Q Heavy Duty Large Tube Fiber Laser Cutting Machine 6000mm Round Square I-Beam H-Beam Profile Cutter with 12000W

SF6036Q Heavy-Duty Large Diameter Tube Fiber Laser Cutting Machine

The SF6036Q is a heavy-duty large diameter tube fiber laser cutting machine, the largest and most powerful tube-only model in the SENFENG lineup. With a 6000mm processing length (customizable for longer), it handles round tubes up to Φ360mm, square tubes up to 280mm, channel steel up to 20#, I-beams up to 25#, and H-beams. The heavy-duty three-jaw pneumatic chuck, thickened integrally welded bed with multiple stress relief treatments, and laser power up to 12000W provide exceptional thick-walled tube cutting capability up to 20mm in carbon steel. Purpose-built for steel structure engineering, bridge construction, shipbuilding, petrochemical, and heavy machinery industries, this is the definitive machine for enterprises requiring large diameter heavy profile processing.

Core Advantages

Industry-Leading 360mm Tube Capacity

With a maximum cutting diameter of Φ360mm for round tubes and 280mm for square tubes, the SF6036Q handles the largest tube sizes in the product lineup. This exceptional capacity is purpose-built for steel structure engineering, bridge construction, and heavy machinery applications where large diameter thick-walled tubes are the primary raw material.

Heavy-Duty Three-Jaw Pneumatic Chuck

The large diameter heavy-duty three-jaw pneumatic chuck delivers exceptional clamping force for the largest and heaviest tube profiles. Its robust design ensures stable, reliable clamping of heavy thick-walled tubes, maintaining precise rotation accuracy throughout extended production runs without slippage or deformation.

Complete Heavy Profile Processing Capability

Full compatibility with the broadest range of heavy structural profiles: round tubes (Φ20-Φ360mm), square tubes (20-280mm), rectangular tubes (20*30 to 280*180mm), channel steel (5#-20#), I-beams (10#-25#), and H-beams. This comprehensive coverage makes it the single-machine solution for heavy fabrication enterprises processing diverse structural steel components.

12000W Ultra-High Power Cutting

Supports fiber laser sources up to 12000W for class-leading thick-walled tube cutting capability. Achieve clean, precise cuts in carbon steel tube walls up to 20mm and stainless steel up to 12mm, covering the complete spectrum of heavy structural tube fabrication requirements.

Heavy-Duty Welded Bed Structure

The thickened integrally welded bed frame with multiple stress relief treatments delivers extreme rigidity for stable, vibration-free cutting under the heaviest workpiece loads. This robust foundation ensures consistent precision across decades of heavy-duty operation in demanding industrial environments.

Professional Heavy Tube Cutting CNC System

The high-end CNC control system supports advanced cutting functions including complex intersecting line cutting, bevel cutting, groove preparation, and multi-axis linkage. These professional-grade capabilities enable single-setup production of complex heavy tube assemblies for structural engineering applications.

Heavy-Duty Adjustable Support System

Multiple heavy-duty adjustable support wheels with enhanced load capacity prevent bending and deformation of large diameter thick-walled long tubes during processing. Precise height and spacing adjustment ensures perfect concentricity with the chuck centerline for consistent cutting accuracy.

Optional Automatic Tube Loading System

A heavy-duty tube automatic loading and unloading system can be integrated for fully automated mass production. This transforms the SF6036Q into a high-throughput manufacturing cell for large-scale structural tube processing operations.

Safety Precautions

• Use crane for large diameter heavy tube lifting; manual handling is strictly prohibited; establish special safety regulations
• Equipment foundation must be constructed as required to ensure sufficient load-bearing capacity and levelness
• Pay attention to chuck stroke and clamping force settings when clamping large diameter tubes to prevent chuck damage
• Select appropriate cutting parameters for thick-walled heavy tube cutting to ensure cutting quality and efficiency
• Adjust height and spacing of heavy-duty support wheels according to tube weight and diameter to ensure concentricity
• Regularly check fastening status of bed connecting bolts and chuck fixing bolts
• Pay attention to scrap handling when cutting large profiles; equip with special material receiving device to prevent equipment damage
• Monitor laser cooling system operation status during high-power cutting to ensure normal water temperature
