Umprotech CNC Tube Bender · Ø5.0in x 20ft · 4.0D Mandrel
All-electric, servo-driven CNC tube bender engineered for US job shops, OEMs, and fabrication cells handling large-diameter tube up to Ø5.0" and lengths to 20 ft. Mandrel bending down to 4.0×D CLR, with multi-radius tooling and advanced automation options for demanding, high-mix production.
Max tube OD: Ø5.0" · Max length: 20 ft · Min CLR: 4.0×D · Axes: 3, 5, or 8 (servo-driven)
Key advantages for US buyers
- Handles large-diameter tube up to Ø5.0" and lengths to 20 ft—ideal for heavy-duty hydraulic, structural, and process lines.
- Mandrel bending down to 4.0×D CLR, with full mandrel extractor, wiper die, and pressure die assist for tight-radius, high-integrity bends.
- All-electric, servo-driven axes deliver repeatable, stackable bends and precise multi-plane geometry for complex assemblies.
- Multi-radius tooling supports part families with varying radii—reduce changeovers and increase throughput for high-mix jobs.
- 3D programming with simulation and anti-collision monitoring minimizes setup risk and protects tooling on intricate tube shapes.
- Optional booster, auto loader/unloader, and weld seam detection for increased automation and process control.
Key technical specifications
Maximum tube OD: Ø5.0"
Accommodates large-diameter tube and pipe for structural, process, and exhaust applications.
Maximum tube length: 20 ft
Supports long stock for chassis rails, process lines, and architectural components.
Minimum centerline radius (CLR): 4.0×D (mandrel supported)
Enables tight-radius bends while controlling ovality and wall thinning—essential for hydraulic and pressure lines.
Axes: All-electric, servo-driven (3, 5, or 8 axes)
Choose the right axis count for your part complexity and automation needs.
Tooling system: Multi-radius, mandrel extractor, wiper die, pressure die assist
Configure for part families or demanding geometries without frequent tool swaps.
Support systems: Anti-wrinkle, auto-lubrication
Maintain surface quality, reduce manual maintenance, and extend tool life in production environments.
Controls & automation: 3D programming, simulation, anti-collision, XYZ/rotation import
Streamline setup, validate bend sequences, and integrate with CAD or tube measuring systems.
Capabilities & typical applications
This CNC tube bender is designed for integration in standalone forming cells or as part of a larger fabrication line with lasers, saws, or welding stations. Its capacity and flexibility make it a strong fit for US shops running high-mix, large-diameter tube jobs.
- Heavy-duty hydraulic and process lines (up to Ø5.0" OD)
- Truck, bus, and off-highway exhaust and chassis members
- Structural and architectural tube work (long, complex bends)
- HVAC, industrial piping, and pressure-rated assemblies
- General large-diameter tube fabrication for job shops and contract manufacturers
- High-mix/low-volume or repeat production requiring tight tolerances and consistent geometry
Implementation & support for US shops
We partner with US job shops and OEMs to ensure every installation is production-ready. Our team reviews your parts, materials, and process flow to confirm fit and optimize configuration before purchase. We support pre-install planning (power, floor space, access), and provide training on programming, tooling strategies, and maintenance.
- Application review: sample parts, thickness, and material checks before order
- Guidance on bend sequences, tooling selection, and simulation setup
- On-site or remote training to get your team productive quickly
- Integration support with upstream (saw, laser) and downstream (welding, assembly) processes
Next step: Send us your sample part drawings or specs (DXF/STEP/PDF) and we’ll confirm fit, recommend configuration, and estimate cycle time for your jobs.
