Umprotech CNC Tube Bender · Ø5.5in x 20ft, 3.0D Mandrel
All-electric, servo-driven mandrel tube bender for US job shops, OEMs, and fabrication cells. Handles up to Ø5.5" tube, 20 ft length, and supports tight-radius bends down to 3.0×D CLR. Designed for structural, hydraulic, and chassis-grade work where repeatability and part integrity are critical.
Max OD: Ø5.5" · Max Length: 20 ft · Min CLR: 3.0×D · Axes: 3, 5, or 8 (servo-driven)
Key advantages for US buyers
- Mandrel bending up to 3.0×D CLR for tight-radius, high-integrity bends on large-diameter tubes.
- Handles tube diameters up to Ø5.5" and lengths up to 20 ft for structural, hydraulic, and chassis assemblies.
- All-electric, servo-driven axes (3, 5, or 8) provide consistent repeatability and precise stackable bends.
- Multi-radius tooling enables complex assemblies with multiple bend radii on a single setup.
- 3D programming and simulation with anti-collision monitoring reduce setup time and protect tooling.
- Automation-ready with booster, auto loader/unloader, and weld seam detection options for high-throughput production.

Capabilities & typical applications
This all-electric CNC tube bender is engineered for integration in standalone forming cells or as part of a complete fabrication line with saws, lasers, and welding fixtures. Its large capacity and tight-radius capability make it a fit for demanding, high-mix or repeat production environments.
- Hydraulic lines and fluid transfer tubes for heavy equipment
- Chassis and frame components for trucks, off-road, and agricultural vehicles
- Structural and architectural tubing for construction and large assemblies
- Exhaust, intake, and aerospace tube sets requiring precise, repeatable bends
- General job shop and contract manufacturing for large-diameter or long tube work
Implementation & support for US shops
We work closely with US job shops and OEMs to ensure a smooth installation and ramp-up. Our team can review your part drawings, materials, and production requirements to confirm fit and recommend the right configuration.
- Pre-installation review: power, floor space, tube handling, and safety
- Part and process validation: sample bends, cycle time estimates, and setup planning
- Training on programming, tooling, and maintenance for fast productivity
- Ongoing support for troubleshooting, upgrades, and process optimization
Next step: Send us your sample parts or drawings, and we’ll confirm fit, cycle time, and the best configuration for your shop.
