Servo-driven accuracy for 1.25″ tube sets

The Umprotech all-electric mandrel CNC tube bender for the US market is engineered for small-diameter tube up to Ø1.25″ and 10 ft length. Fully servo-driven axes deliver repeatable, stackable bends with tight tolerance control—ideal for dense tube routings, manifolds, and light-frame assemblies.

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. The integrated anti-wrinkle system keeps thin-wall and high-strength tubes stable when running aggressive layouts.

Multi-radius tooling and clean flow

Multi-radius tooling lets you configure multiple CLR stations on a single setup—perfect for parts that mix tight crossovers with longer sweeps. Auto-lubrication maintains mandrels, dies, and sliding elements for long tool life, consistent surface finish, and reduced manual maintenance in both production and prototype environments.

3D programming, simulation, and anti-collision

The control platform delivers 3D programming with simulation so operators can verify bend sequences before cutting metal. XYZ/rotation import simplifies programming from CAD or measuring systems, while anti-collision monitoring helps protect small-diameter tooling, mandrel, and machine structure when bending complex multi-plane shapes.

Automation and high-mix 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 cut-to-length blanks. A weld seam detection option maintains seam orientation for safety-critical and cosmetic assemblies in small-diameter tube.

*Actual performance varies with material grade, wall thickness, tooling design, and process setup.
