Servo-driven accuracy for 3″ tube up to 14 ft
The Umprotech all-electric mandrel CNC tube bender for the US market is built for mid- to large-diameter tube up to Ø3.0″ and 14 ft length. Fully servo-driven axes deliver repeatable, stackable bends with tight tolerance control—ideal for hydraulic lines, structural members, and chassis components where routing is complex and consistency is critical.
Mandrel support up to 3.0×D CLR
A complete mandrel package with mandrel extractor, wiper die, and pressure die assist supports centerline radii up to 3.0×D, helping control ovality, collapse, and wall thinning on tight-radius bends in 3″ tube. The integrated anti-wrinkle system stabilizes thin-wall and high-strength tubing when working near process limits across the full 14 ft envelope.
Multi-radius tooling and controlled flow
Multi-radius tooling lets you set up multiple CLR stations on the same machine—ideal for parts that mix tight crossovers, offsets, and sweeping arcs. Auto-lubrication maintains mandrels, dies, and sliding elements for long tool life, consistent surface finish, and reduced manual maintenance in continuous production.
3D programming, simulation, and anti-collision
The control platform provides 3D programming with simulation so operators can validate bend sequences and clearance before cutting metal. XYZ/rotation import streamlines programming from CAD or measuring systems, while anti-collision monitoring helps protect tooling, mandrel, and machine structure when bending complex multi-plane shapes with long stick-outs.
Automation and throughput options
Expand capability with an optional booster for ultra-tight radii within the 3.0×D envelope, plus auto loader/unloader systems for hands-off handling of 14 ft blanks. A weld seam detection option keeps seam orientation under control for safety-critical, pressure-rated, and cosmetic assemblies.
*Actual performance varies with material grade, wall thickness, tooling design, and process setup.
