Umprotech CNC Tube Bender · Ø4.5in x 20ft · 3.0D Mandrel
All-electric mandrel CNC tube bender engineered for US job shops, OEMs, and fabrication cells. Handles up to Ø4.5" tube, 20 ft lengths, with mandrel support for tight 3.0×D centerline radii. Ideal for high-spec, mid- to large-diameter tube work where repeatability, surface quality, and flexible setups matter.
Max tube OD: Ø4.5" · 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 on tubes up to Ø4.5" and 20 ft long.
- Mandrel package supports tight 3.0×D CLR for demanding layouts and high-spec hydraulic/process lines.
- Multi-radius tooling enables multiple bend radii in a single setup—ideal for complex assemblies and reduced changeover.
- 3D programming with simulation and anti-collision monitoring reduces setup time and helps protect tooling and parts.
- Available in 3-axis, 5-axis, or 8-axis configurations to match your automation, rotation, and part complexity needs.
- Options for booster bending, auto loader/unloader, and weld seam detection support higher throughput and safety-critical work.

Capabilities & typical applications
This CNC tube bender is a core asset for standalone forming cells or as part of an integrated fabrication line with saws, lasers, and welding fixtures. Its capacity and mandrel support make it a strong fit for both high-mix and repeat production environments.
- Hydraulic and process lines requiring tight-radius, high-integrity bends
- Automotive and truck exhaust, chassis, and frame components up to Ø4.5" OD
- HVAC, industrial piping, and architectural tube work
- General mid-large diameter tube fabrication for job shops and OEMs
- Assemblies with multiple radii or complex multi-plane geometry
Implementation & support for US shops
We work closely with US fabricators, job shops, and OEMs to ensure a smooth commissioning process. Our team can review your parts, materials, and thickness ranges to confirm fit and recommend the right axis configuration and tooling.
We provide guidance on floor layout, power requirements, and safe material flow. Training covers 3D programming, bend sequence validation, and basic maintenance, so your team is productive quickly.
- Pre-install checks: power, floor, access, and safety review
- Sample part review and process confirmation before purchase
- Support for programming, tooling strategies, and bend sequence optimization
- Onsite or remote training and handover
Next step: Send us a few sample parts (DXF/STEP/PDF) and we'll confirm fit, cycle time, and configuration for your application.
