Profile bending machines, also known as section bending machines, angle rollers, or angle roll machines, are industrial machines that can bend and shape a variety of materials, including metal, plastic, and wood, into curved shapes or profiles. In this article, we will discuss what a profile bending machine is, how it works, and the different types of profile bending machines available.
Profile Bending Machines: Types and Applications
A profile bending machine is an industrial machine that uses rollers to bend and shape a wide range of materials into curved shapes or profiles. The machine consists of a set of rollers, each of which has its own motor and controller, that work together to apply pressure to the material being bent. The rollers can be adjusted to apply different levels of pressure, depending on the thickness and rigidity of the material.
Profile bending machines are used in a range of industries, including construction, architecture, automotive, and aerospace, to create curved profiles for building frames, car frames, airplane wings, and other structures. These machines are designed to be durable, safe, and accurate, making them an essential piece of equipment for many industrial applications.
How Does a Profile Bending Machine Work?
A profile bending machine works by using a set of rollers to apply pressure to a material as it passes through the machine. The rollers are calibrated to apply the right amount of pressure, which creates the desired curve or profile in the material.
The process generally involves feeding the material into the machine, where it is held in place by a series of clamps or fixtures. The machine then rotates the material past the rollers, which apply pressure and bend the material into the desired shape. The material can be fed through the machine multiple times to create more complex shapes or to refine the curve.
Modern profile bending machines are highly advanced, using computer-controlled systems to ensure precise bending and shaping of the material. This technology also allows for the creation of more complex shapes and angles than would be possible with traditional bending techniques.

Programming Capability of the CNC Profile Bending Machine
One of the most important features of any profile bending machine is its programming capability. Simple programming allows operators to quickly and easily input the desired bend specifications, even for complex and multi-radius bends.
To achieve this level of simplicity, modern CNC profile bending machines for aluminum often incorporate user-friendly programming interfaces that are designed to be intuitive and easy to use. This allows operators to learn to bend complex profiles in a single day, regardless of their level of experience or skill.
One such feature that improves programming is the use of touchscreen interfaces, which provide a convenient way to input specifications, check part programs, and make adjustments on the fly. Additionally, many angle rollers come with pre-programmed settings that can be used as starting templates when creating new part programs, further simplifying the process.
Another important factor to consider is the ability of the machine to handle tangents and multi-radius bends. These features can add complexity to the bending process and require greater precision and accuracy. However, with the right programming, modern profile bending machines for aluminum can easily handle these types of bends, producing clean and accurate results every time.
Overall, simple programming is a critical feature of any successful profile bending machine for aluminum. By allowing operators to quickly and easily input complex bend specifications, these machines help to streamline the production process and ensure consistent and high-quality results.
Top 10 must-have features of the best profile bending machine
A profile bending machine(also called angle roller) is a piece of equipment designed to bend metal profiles, such as beams, tubes, and bars, into specific shapes or curves. Some features commonly found in modern profile bending machines include:
Digital controls
CNC profile bending machines for aluminum often have digital controls that allow for precise and accurate control over the bending process. This can be especially important when working with delicate or complex profiles.
Precision rollers
Aluminum is a soft metal, which means that it requires precise and gentle handling during the bending process. Many profile bending machines for aluminum are equipped with precision rollers that are specially designed to prevent damage to the material.
Re-bending app
Built-in app that allows operators to calculate and visualize the effects of re-bending a profile. This can be useful when trying to achieve precision and minimize waste.
PBA aluminum profile bending machines include a re-bending app that can help operators achieve more efficient and precise results. This can be especially useful in situations where a profile is made of a harder material or is more complex than anticipated.
If a section is a little harder material you can re-bend this automatically including the tangents to produce a good part instead of a scrap one
Bend feed-back and re-calculation app
Metal bars have slightly different harnesses from batch to batch. This gives different bend results when using and CNC bending machine due to the differing spring back. PBA profile bending machines may allow operators to measure and input the desired bend radius, as well as other parameters such as the angle of bend or shape of the profile. By inputting this information into the machine, operators can help ensure that the correct amount of spring back is accounted for during the bending process, resulting in more accurate and consistent bends.
Spring back
Accounting for slight variations in the hardness or material properties of metal bars is an important consideration when using a profile bending machine for aluminum. These variations can result in different levels of “spring back” or elasticity, which can affect the accuracy of the bending process.
To address this issue, many modern profile bending machines for aluminum incorporate digital measurement and customization features that allow operators to input specific parameters relating to the material being used. For example, the machine may be equipped with sensors that can detect the hardness of the material, which can then be used to automatically adjust the bending process to suit.
In addition to detecting hardness variations, profile bending machines may also allow operators to measure and input the desired bend radius, as well as other parameters such as the angle of bend or shape of the profile. By inputting this information into the machine, operators can help ensure that the correct amount of spring back is accounted for during the bending process, resulting in more accurate and consistent bends.
Repeatability and accuracy
Modern profile bending machines are designed to be highly repeatable and accurate, allowing for consistent and reliable results.
PBA servo electric aluminum profile bending machines for aluminum are known for their excellent repeatability and accuracy. This is because servo electric motors offer precise and repeatable movement, allowing for accurate positioning and easy adjustment of the bending angle.
- Multi-axis control: PBA profile bending machines for aluminum have multi-axis control systems that allow for greater flexibility and precision when bending complicated profiles.
- Accurately controlled ‘Z’ axis: The ‘Z’ axis refers to the position of the bending arm or roller in relation to the profile being bent. Accurately controlling this axis is critical for achieving consistent and precise results. When forming non-symmetrical sections, PBA CNC aluminum profile bending machines can be able to control the twist of the section accurately.
Variable centers
PBH profile bending machines are designed to accommodate variable centers, allowing for greater flexibility in the types of profiles that can be bent.
