Descripción
Umprotech CNC Tube Bender – Ø6.0in x 20ft, 4.0D Mandrel
All-electric, servo-driven CNC tube bender engineered for US job shops, OEMs, and fabrication cells. Handles up to Ø6.0" tube, 20 ft lengths, and 4.0×D mandrel bending for demanding structural, hydraulic, and chassis applications.
Max Tube OD: Ø6.0" · Max Length: 20 ft · Mandrel CLR: up to 4.0×D · Axes: 3, 5, or 8 (servo-driven)
Key advantages for US buyers
- All-electric, servo-driven axes for precise, repeatable bends on large-diameter tubes up to Ø6.0" and 20 ft long.
- Mandrel bending up to 4.0×D CLR—ideal for both gentle sweeps and moderately tight radii on structural and high-strength tubes.
- Multi-radius tooling supports complex part geometries and reduces changeover time for high-mix production.
- Integrated anti-wrinkle system and pressure die assist help maintain tube integrity, even on thin-wall or high-strength materials.
- 3D programming with simulation and anti-collision monitoring streamlines setup and protects tooling during long, multi-stack bends.
- Automation-ready: booster for tight radii, optional auto loader/unloader, and weld seam detection available for high-throughput lines.
Key technical specifications
Max tube OD: Ø6.0"
Handles large-diameter hydraulic, structural, and process tubes without compromise.
Max tube length: 20 ft
Supports long-run parts for chassis, construction, and architectural assemblies.
Mandrel bending: up to 4.0×D CLR
Delivers a wide bending envelope—from gentle sweeps to moderately tight radii—while controlling ovality and surface finish.
Axes: 3, 5, or 8 (servo-driven)
Choose the right level of automation and flexibility for your part complexity and throughput needs.
Tooling & support: Multi-radius tooling, mandrel extractor, wiper die, pressure die assist, anti-wrinkle system, auto-lubrication
Engineered for consistent results and long tool life, even in demanding production environments.
Controls: 3D programming, simulation, XYZ/rotation import, anti-collision
Streamlines programming from CAD or measuring arms and reduces setup risk for long, heavy tubes.
Capabilities & typical applications
This CNC tube bender is designed for integration into standalone cells or as a complement to fiber lasers, saws, and welding fixtures. Its capacity and flexibility serve both high-mix job shops and OEM production lines.
- Structural frames, chassis rails, and roll cages for construction and agricultural equipment
- Hydraulic and process lines for industrial machinery and heavy-duty vehicles
- Exhaust, intake, and fluid handling systems for automotive and aerospace
- Architectural features and large-radius handrails for commercial and public spaces
- Suitable for high-mix/low-volume prototyping or repeat production of long, large-diameter parts
Implementation & support for US shops
Our team works closely with US job shops and OEMs to ensure every installation is a success. We review your floor space, power, and material flow requirements, and can validate your parts and thickness ranges before purchase. Our support covers:
- Pre-installation planning: power, access, and safety checks
- Part review and bend sequence validation for your typical jobs
- Basic programming, tooling setup, and best practices for mandrel bending
- On-site training and commissioning to get your team productive quickly
Next step: Send us your sample parts or drawings (DXF/STEP/PDF) and we’ll confirm fit, cycle time, and optimal configuration for your needs.
