Servo-driven accuracy for large-diameter tube
The Umprotech all-electric mandrel CNC tube bender for the US market is built for precision on larger tube sizes, handling up to Ø5.5″ and 20 ft tube length. Fully servo-driven axes deliver repeatable, stackable bends with tight tolerance control, ideal for structural, hydraulic, and chassis-grade geometries.
Mandrel support up to 3.0×D CLR
A robust mandrel package with mandrel extractor, wiper die, and pressure die assist supports centerline radii up to 3.0×D, controlling ovality and wall thinning on tight-radius bends. The integrated anti-wrinkle system stabilizes thin-wall and high-strength tubes, even when pushing large OD bends close to the limit.
Multi-radius tooling and clean, consistent flow
Multi-radius tooling keeps multiple CLR setups on one machine, ideal for assemblies that mix gentle sweeps and tight bends on the same tube. Auto-lubrication protects mandrels, dies, and sliding surfaces, maintaining surface finish and geometry over long production runs.
3D programming, simulation, and anti-collision
The control platform offers 3D programming with simulation so operators can validate bend sequences before cutting metal. XYZ/rotation import streamlines programming from CAD models or measuring arms, while anti-collision monitoring helps protect tooling, mandrel, and machine structure when handling long, heavy tubes.
Automation and high-throughput options
Productivity can be elevated with a booster for ultra-tight radii, plus auto loader/unloader systems to automate long-tube handling. A weld seam detection option keeps seam orientation under control for safety-critical and cosmetic assemblies.
*Actual performance varies with material grade, wall thickness, tooling design, and process setup.
