Umprotech CNC Tube Bender · Ø4.0in x 20ft · 3.0D Mandrel
All-electric mandrel CNC tube bender engineered for US fabrication shops, OEMs, and automation cells. Handles up to Ø4.0" tube, 20 ft length, and tight 3.0×D CLR bends with servo-driven precision. Ideal for mid- to large-diameter tube assemblies requiring repeatable, high-spec results.
Max Tube OD: Ø4.0" · Max Length: 20 ft · Mandrel CLR: up to 3.0×D · Axes: 3, 5, or 8 (servo-driven)
Key advantages for US buyers
- All-electric, servo-driven axes deliver consistent, repeatable bends up to Ø4.0" and 20 ft tube lengths.
- Mandrel package supports tight 3.0×D centerline radii for high-spec, thin-wall, or high-strength tubing.
- Multi-radius tooling enables complex assemblies with both tight crossovers and broad sweeps on a single setup.
- 3D programming and simulation with anti-collision protection reduce setup time and protect tooling.
- Available in 3-, 5-, or 8-axis configurations to match your automation and part complexity needs.
- Optional auto loader/unloader and weld seam detection streamline high-throughput, hands-off production.

Capabilities & typical applications
This CNC tube bender is a core asset for forming cells, welding prep, and integrated production lines. Its capacity and mandrel support make it a fit for both contract manufacturing and OEM environments handling high-mix, high-spec tube work.
- Hydraulic and process lines requiring precise, repeatable bends
- Automotive and truck exhaust systems, chassis, and frame components
- HVAC and industrial piping with long or multi-radius runs
- Architectural tube work and custom fabrication projects
- Assemblies with thin-wall or high-strength tubing at aggressive CLR values
- High-mix/low-volume prototyping and repeat production in job shops
Implementation & support for US shops
We work closely with US job shops, OEMs, and integrators to ensure a smooth commissioning process. Our team reviews your tube specs, materials, wall thickness, and part drawings to confirm fit and optimal configuration before purchase.
- Pre-installation review of power, floor space, and material flow
- Assistance with basic programs, bend sequences, and tooling strategies
- Operator training and handover for rapid productivity
Next step: Send us your sample parts or tube drawings (DXF/STEP/PDF) and we’ll confirm cycle time, fit, and recommended configuration for your application.
