Umprotech CNC Tube Bender – Ø6.0in x 20ft, 3.0D CLR (Mandrel)
Heavy-duty, all-electric CNC tube bender engineered for US job shops, OEMs, and automation cells. Handles up to Ø6.0″ tube, 20 ft lengths, and 3.0×D CLR with full mandrel support. Built for high-precision, high-mix tube bending where repeatability and tight radii matter.
Max tube OD: Ø6.0″ · Max length: 20 ft · Max CLR: 3.0×D · Axes: 3, 5, or 8 (servo-driven)
Key advantages for US buyers
- All-electric, servo-driven axes deliver repeatable accuracy on large-diameter tube up to Ø6.0″ and 20 ft lengths.
- Mandrel bending supports tight 3.0×D CLR, minimizing ovality and wall thinning for structural, hydraulic, and chassis applications.
- Multi-radius tooling and quick-change capability for complex parts with both gentle sweeps and tight bends on a single setup.
- 3D programming with simulation and anti-collision monitoring reduces setup time and protects tooling when handling long, heavy tubes.
- Optional booster, auto loader/unloader, and weld seam detection support high-throughput, safety-critical, and production environments.
- Available in 3-axis, 5-axis, and 8-axis configurations to fit a range of automation and part complexity needs.

Capabilities & typical applications
This CNC tube bender is designed for integration in high-mix fabrication cells, large-part production, or as a standalone solution for demanding tube work. Its 6.0″ OD and 20 ft length envelope make it ideal for:
- Heavy-duty hydraulic and process lines
- Structural and chassis tubing for vehicles and equipment
- Construction and agricultural machinery frames
- Exhaust and intake systems for industrial and off-road vehicles
- Architectural tube features and large-radius bends
- Aerospace and defense tube assemblies
- Job shops handling high-mix/low-volume or repeat production of large-format tube parts
Implementation & support for US shops
We work closely with US job shops, OEMs, and integrators to ensure a smooth implementation. Our team reviews your parts, material specs, and floor plan to confirm fit and utility requirements before purchase. We assist with programming, tooling strategies, and bend sequencing to get your team productive quickly.
- Pre-installation review of power, floor space, and material flow
- Application review for tube size, wall thickness, and part complexity
- Training on 3D programming, simulation, and safe operation
- Support for integration with upstream saws, lasers, or downstream welding cells
Next step: Send us your sample parts or drawings (DXF/STEP/PDF) and we’ll confirm fit, cycle time, and best configuration for your workflow.
