About CNC Tube Bending
CNC tube bending utilizes computer-controlled machinery to achieve highly precise and repeatable bends in metal tubing. This automated process translates digital designs into complex multi-plane geometries, including tight radii, compound curves, and back-to-back bends. It supports a wide range of materials—such as stainless steel, aluminum, and copper—across various diameters and wall thicknesses. Precision tooling, often including internal mandrels, maintains cross-section integrity and minimizes deformation, even for thin-walled or high-strength alloys. This capability is essential for producing consistent, high-accuracy tubular components efficiently, meeting exact specifications for prototypes, low-volume runs, or complex assemblies across industries.

High-Precision, Repeatable Bends for Complex Components
Achieve consistent, multi-angle accuracy (±0.1°) with our computer-controlled rotary draw bending process. Using
precision dies and mandrels, we cold-form tubes (OD: 6mm–75mm | Walls: 0.5–4mm) while maintaining cross-section
integrity across radii from 2×D to 12×D. This method is ideal for applications like exhaust systems, roll
cages, and chassis components requiring tight tolerances and repeatability.
Leverage ISO 9001-certified workflows to accelerate production—from rapid prototyping to high-volume runs. We deliver structurally critical parts faster than traditional sourcing, without compromising on precision or quality.

Unmatched Geometric Flexibility for Complex tubular Designs
Experience maximum design freedom with advanced hybrid tube bending technology, which seamlessly integrates rotary draw and roll bending within a single CNC platform which enables the production of multi-radius bends and curves without the need for retooling between operations. Capable of processing tubes from 6mm to 75mm OD with wall thicknesses of 0.5–4mm, this method accommodates both tight radii (as low as 2D) and large sweeping curves (≥7×D) in a single setup.
Our ISO-certified manufacturing partners produce multi-radius components in a single operation for complex prototypes, and low-volume production runs.
CNC Laser Cutting for Tubular Components
Quick Quote
Precision Preparation for Flawless Bending and Assembly
Multi-axis CNC laser cutting technology delivers ultra-precise, burr-free cuts on tubular structures with complex geometries. This process ensures clean, ready-to-bend components with ±0.5mm positional and ±0.1mm dimensional tolerance, eliminating the need for secondary machining and minimizing material waste. Ideal for notching, hole patterning, and end-forming on stainless steel, aluminum, and alloys, our laser cutting systems prepare tubes up to 75mm OD.
By integrating laser cutting with our bending capabilities, we offer a streamlined, single-source solution that reduces production steps and accelerates turnaround.
CNC Tube Bending Tolerances
This table shows the typical precision levels for different tube bending methods. Mandrel and Hybrid bending offer the tightest accuracy for demanding projects, like aerospace parts. Rotary Draw bending provides reliable consistency for most industrial needs. Roll bending is ideal for simpler, large-curve applications where ultra-high precision isn’t required. All methods ensure trusted performance for your designs.
