Precision Tube Bending Capabilities & Tolerances | Wooley Manufacturing | Great Lakes Region, Michigan

Advanced CNC Tube Bending

At Wooley Manufacturing, we specialize in precision tube bending services powered by the Horn Metric CNC18MBE, a hybrid CNC tube bender engineered for high-performance and tight-tolerance applications. Whether you're working with mild steel, stainless steel, or non-ferrous metals, our CNC tube bending capabilities ensure consistent, repeatable results across complex geometries and demanding specifications.


Key Features of our Horn Tube Bender


  • Hybrid Electric/Hydraulic Drive: Combines servo-electric bending and tube positioning with hydraulic tooling actuation for optimal control and force.
  • Dual-Stack Tooling: Enables both mandrel bending for tight radii and roll bending for large-radius sweeps.
  • BendPro CNC Controls: Offers full simulation capabilities for precision programming and reduced setup time.
  • Servo-Driven Axes:
    • Bend-arm (C-axis) via planetary transmission
    • Carriage (Y-axis) with push-roll capability
    • Collet (B-axis) rotation for multi-plane bending
  • Hydraulic Tooling Actuation: Clamp, pressure die, and mandrel systems are hydraulically driven with early withdrawal for wrinkle-free bends.
  • Automatic Mandrel Lubrication & Tube Support: Enhances tool life and bend quality.
  • Environmentally Friendly: Low power consumption, reduced noise, and minimal heat output.

Tube Bending Tolerances

Our CNC tube bending process adheres to industry-standard tolerances, including:

  • Bend Angle Accuracy: ±0.25°
  • Bend Radius Consistency: ±0.010 in (±0.25 mm)
  • Ovality Control: Maintained within ±10% of nominal diameter
  • Wall Thinning: Typically less than 15%, depending on material and bend radius
  • Repeatability: High precision across production runs due to servo-controlled motion and CNC programming


    • Applications

    Our tube bending services support a wide range of industries, including:

    • Automotive and Off-Road
    • HVAC and Refrigeration
    • Aerospace and Defense
    • Medical Equipment
    • Industrial Machinery

    Whether you need prototype development, low-volume production, or high-volume manufacturing, our CNC tube bending capabilities deliver unmatched precision and efficiency.
