Unlike manual roll bending or standard roll bending machines, the TR20RL provides
programmable control of coil direction and multiple radii within a single part. This CNC
Horizontal Roll Bender is designed to form right-hand or left-hand coils with programmable clockwise (CW) or counterclockwise (CCW) bending. This CNC Roll Bender is built for flexibility and repeatability. It allows manufacturers to produce coiled tubing, heat transfer coils, and variable-radius parts without relying on manual bending methods.
With CNC program storage and a programmable servo electric ram, the TR20RL supports
multiple-radius bending in a single workpiece, helping teams improve consistency and reduce setup time even in low-volume production.

CNC Roll Bending for Right- & Left-Hand Coils
The TR20RL allows manufacturers to produce either clockwise (CW) or counterclockwise (CCW) coils on a single machine, eliminating additional setups while improving repeatability across production.
One Machine. Two Coil Directions.
Operators can program the TR20RL for either right-hand or left-hand coil production, making the machine adaptable to a wide range of part geometries and industry requirements.
Switching coil direction is handled through CNC programming, eliminating the need for separate machines or manual adjustments between jobs.
Without CNC Roll Bending
- Repeat parts require re-measuring and layout.
- Multi-radius parts are difficult to reproduce.
- Results depend heavily on operator skill.
With the TR20RL
- Programs are stored and reused.
- Coil direction is programmable (CW/CCW).
- Multiple radii are CNC controlled.
- Repeatable results from part to part.
Multiple-Radius CNC Bending in a Single Part
A programmable servo-electric ram allows the TR20RL to produce multiple radii within a single workpiece, reducing secondary operations while improving repeatability for complex tube geometries.
Built for Heat Transfer and High-Pressure Applications
The TR20RL is commonly used where tubing must reliably transfer heat, pressure, or both. CNC roll bending helps manufacturers create consistent coil geometries for demanding industrial applications.
Heat Transfer
Coiled tubing is widely used to move heat from one medium to another. The TR20RL supports consistent coil formation across a range of thermal management and fluid movement applications.
High-Pressure & Delay Lines
The machine is also suited for forming steel and stainless-steel transfer lines used in high-pressure systems where repeatable geometry and controlled routing are essential.
Build the Part Once. Run It Again Later.
Manual roll bending often requires templates, tape measures, and repeated adjustments every time a part is recreated. With the TR20RL, operators can program the part, save the setup, and return to it later with minimal preparation.
This improves consistency while reducing time spent recreating parts, making the system especially valuable for repeat and low-volume production.

Built for Production Safety
The machine includes multiple safety features designed for industrial manufacturing environments, including:
Customizable for Tube Diameter Requirements
The standard system is designed around a targeted tubing range, designed for high-volume tube production.
However, Winton can customize the tube magazine loader and automatic tube feeding system configuration for different tubing diameter requirements and production needs.
Because high-volume automated tube production is often dedicated to a specific tubing size or narrow diameter range, systems are typically designed for repeatable production within a targeted range.
Frequently Asked Questions
What is a CNC horizontal roll bender used for?
A CNC horizontal roll bender is used to form tubing into coils or large-radius bends, including right-hand or left-hand coils for heat transfer, pressure systems, and structural applications.
Can the TR20RL bend both right hand and left-hand coils?
Yes. The TR20RL can be programmed for either right-hand or left-hand coil bending.
Operators select the required coil direction for the part program, allowing the machine to
produce CW or CCW coils depending on the application. It does not bend both
directions simultaneously in the same operation.
Can this machine bend multiple radii in one part?
Yes. The programmable electric ram allows multiple-radius bending within a single workpiece.
Why use CNC instead of manual roll bending?
CNC roll bending improves repeatability, reduces setup time, and allows programs to be stored and reused instead of manually recreating parts.
