Servo-driven accuracy for fine tube assemblies
The Umprotech all-electric mandrel CNC tube bender for the US market is optimized for small-diameter tube up to Ø1.0″ and 10 ft length. Fully servo-driven axes give you repeatable, stackable bends with tight tolerance control—ideal for compact, high-density tube routings 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 and collapse on tight-radius small tube. The integrated anti-wrinkle system keeps thin-wall and high-strength tubing stable when bending close to the process limits.
Multi-radius tooling and clean flow
Multi-radius tooling lets you run multiple CLR setups on a single machine, perfect for compact tube sets that mix tight crossovers with gentle sweeps. Auto-lubrication maintains mandrels, dies, and sliding elements for long tool life, consistent surface finish, and reduced manual maintenance in production or prototype environments.
3D programming, simulation, and anti-collision
The control platform delivers 3D programming with simulation so operators can verify bend sequences before running production. 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
Extend 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 keeps seam orientation under control for safety-critical and cosmetic assemblies in small tube sizes.
*Actual performance varies with material grade, wall thickness, tooling design, and process setup.
