Umprotech CNC Tube Bender · Ø3.0in x 20ft · 4.0D Mandrel
All-electric mandrel CNC tube bender engineered for US job shops, OEMs, and fabrication cells requiring precise, repeatable tube bending up to Ø3.0" and 20 ft length. Designed for demanding applications where tight radii and high surface quality are critical.
Capacity: Ø3.0" · Max Length: 20 ft · Mandrel CLR: up to 4.0×D · Axes: 3, 5, or 8 (servo-driven)
Key advantages for US buyers
- Mandrel bending up to 4.0×D CLR supports both gentle sweeps and tight layouts for a wide range of tube assemblies.
- All-electric, servo-driven axes ensure repeatable, high-precision bends for consistent part quality in production runs.
- Handles tube diameters up to Ø3.0" and lengths up to 20 ft—ideal for long hydraulic lines, HVAC coils, automotive frames, and structural components.
- Multi-radius tooling and quick-change features enable efficient setups for high-mix, low-volume or batch production.
- 3D programming with simulation and anti-collision monitoring reduce setup time and protect tooling during complex multi-plane bending.
- Automation-ready with options for booster bending, auto loader/unloader, and weld seam detection for lights-out or safety-critical operations.

Capabilities & typical applications
This CNC tube bender is a core tool for high-precision tube fabrication, whether as a standalone cell or integrated with saws, lasers, or welding stations. Its envelope and mandrel capability make it suitable for both prototype and production environments.
- Automotive and motorsports lines: roll cages, chassis tubes, and exhaust systems
- HVAC and refrigeration circuits: long coils and custom bends
- Hydraulic and pneumatic tubing: industrial and mobile equipment assemblies
- Furniture frames and architectural elements
- Medical and laboratory systems: precision tube sets
- General fabrication: light structural tube work and custom assemblies
- High-mix/low-volume jobs, repeat orders, and prototyping
Implementation & support for US shops
We work closely with US job shops, OEMs, and fabricators to ensure a smooth commissioning process. Our team reviews your parts, materials, and process needs to confirm the right configuration before purchase. We support you through installation, basic programming, tooling strategies, and operator training—so your team is productive from day one.
- Pre-installation review: power, floor space, material flow, and safety
- Sample part review: confirm fit, cycle time, and best practices
- Operator training and handover for efficient ramp-up
- Ongoing support for programming, maintenance, and process optimization
Next step: send us your sample tube drawings (DXF/STEP/PDF) and we’ll confirm fit, cycle time, and recommend the optimal configuration for your workflow.
