Umprotech CNC Tube Bender – Ø3.0in, 20ft, 3.0D Mandrel
All-electric, servo-driven mandrel tube bender for US job shops and OEMs requiring precise, repeatable bends in long, mid-to-large diameter tubing. Designed for complex routing, high-mix production, and reduced manual intervention.
Max tube OD: Ø3.0" · Max length: 20 ft · Mandrel CLR: up to 3.0×D · Axes: 3, 5, or 8 (servo-driven)
Key advantages for US buyers
- Handles tube diameters up to Ø3.0" and lengths up to 20 ft—ideal for hydraulic lines, structural members, and long assemblies.
- Mandrel bending up to 3.0×D CLR with mandrel extractor, wiper die, and pressure die assist—controls ovality and wall thinning on tight-radius bends.
- All-electric, servo-driven axes deliver repeatable, stackable bends and tight tolerance control for high-mix and complex parts.
- Multi-radius tooling supports setups with multiple CLR stations—efficient for long parts with crossovers, offsets, and sweeping arcs.
- 3D programming, simulation, and anti-collision features streamline setup and reduce risk of tooling or part damage.
- Expandable with booster for ultra-tight radii, auto loader/unloader for 20 ft blanks, and weld seam detection for critical assemblies.

Capabilities & typical applications
This CNC tube bender is engineered for shops needing precise, repeatable bends in long, mid- to large-diameter tubing. It fits seamlessly into forming cells, complements laser and saw cutting lines, and supports high-mix, low-volume, or repeat production.
- Heavy-duty hydraulic and process lines up to 20 ft
- Automotive, off-highway, and powertrain tube sets (chassis, exhaust, cooling)
- HVAC, process piping, and architectural handrails up to Ø3.0"
- Structural members and long frames for machinery or construction
- High-mix/low-volume fabrication, prototyping, and contract manufacturing
Implementation & support for US shops
Our team understands the demands of US fabrication, job shop, and OEM environments. We assist with pre-installation checks—power, floor space, tube flow, and safety—plus review your parts and materials to confirm fit before purchase.
We support your team with programming guidance, tooling strategies, and bend sequence optimization. Training and handover are coordinated to ensure your operators are productive from day one.
- Pre-installation planning for 20 ft tube handling and shop layout
- Sample part review (DXF/STEP/PDF) to validate process fit
- Guidance on tool selection, maintenance, and automation integration
Next step: Send us your sample parts or process requirements, and we’ll confirm fit, cycle time, and ideal configuration for your shop.
