Advantage of Aluminium Bending Machine PBA
Consistent accuracy; Consistent shape production; Simple development of irregular shapes; and Reliability for both low and high volumes.
Repeatability and Accuracy: Fully servo-driven for commonly used models provides higher repeat positioning accuracy ≤0.01mm. Allows for precise control over aluminum bending, which results in greater accuracy and repeatability.
Adjustable Distance Front Roller: Operators maximize the machine’s capabilities by adjusting variable centers to accommodate different workpieces, ensuring optimal bending quality and the smallest bending radii.
Springback Quick Solution: PBA’s CNC system addresses springback for precise aluminum bending. Operators measure the actual radius to find the compensation coefficient, streamlining production with a quick two-step process for enhanced efficiency.
Historically, precision aluminum extrusion roll bending has required three principal elements: operator skill, repeat position accuracy, and Automatically correct and compensate for dimensional tolerances caused by the material characteristics of aluminum profiles. Today the last two have made it possible to bring a relatively low-skilled operator up to speed in precision aluminum bending very quickly.

- Conventional machines: Variable frequency drive motor driving gear reducer, transitioning through a universal joint drive shaft, torque increases with speed, large motor inertia, leading to poor system stability and low positioning accuracy.
Top 2 features of the X and Y-axis Ensure: Month to month, even the most complex profiles can be bent precisely and consistently!
Horizontal Positioning is Preferred
- PBA aluminum bending machines are vertical spindle and horizontal installations that high-precision bending for aluminum profiles of varying lengths, and are best suited for handling long, narrow workpieces, and also good for creating tight bends without deformities.
- Vertical aluminum bending machines not suitable for processing biger aluminum profiles, can be more difficult to operate and they’re not as precise as horizontal machines.
Notes: When bending large workpieces or large-diameter aluminum profiles, horizontal positioning is preferred. Proper support in the chosen position prevents the weight of the workpiece from affecting the final results. Bending in a horizontal position is also utilized to address clearance issues at customer facilities.
X-axis Variable Center Distance
- PBA is the variable geometry aluminum profile bending machine, variable centers adjust the machine to perform like a large or small machine, and are suitable for bending aluminum profiles and for heavy metal fabrication work.
- Conventional machines: The X-axis center distance of commonly used aluminum profile bending machines for door and window profiles in the market is not adjustable.

Before inquiring about an aluminum bending machine, it’s essential to gather pertinent information to ensure we recommend an informed decision aligning with your specific bending requirements.
Aluminum Alloys: Note the specific aluminum alloys you’ll be bending (e.g., 6061-T6). The hardness state of aluminum is important.
Drawings: Drawings of aluminum extrusions and bending process drawings. - Which aluminum profiles can be bent?
Aluminum profiles come in various sizes and specifications, and their bending capability depends on several factors (bending method, equipment, and bending radius). For example, extrusions with wall thicknesses from 2 to 15 mm can be bent, with bending radii as small as 300 mm. These are all possible.
When handling larger profiles, using the right machinery is crucial. This machinery carefully applies controlled force during the bending process to maintain the profile’s structural integrity.
The most common aluminum extrusion bending processes are roll bending, stretch bending, and mandrel bending. The method you choose should depend on the type of profile you’ve designed, its application, and production quantity.If you have aluminum bending requirements, you can consult the BIT aluminum bending team. With over 20 years of experience, we can help you achieve the perfect aluminum bend.
- What Alloys Are Best for Aluminium Bending?
In the industry, several commonly used aluminum alloys are ideal for bending due to their properties:
- 6063: Known for its superb formability and corrosion resistance, making it ideal for architectural applications.
- 5052: Offers high strength and good formability, commonly used in marine and automotive industries.
- 6061: Versatile with strong mechanical properties, suitable for structural applications when bent with the right techniques.
- 3003: Good for general-purpose bending, with decent formability and corrosion resistance, though not as strong as other alloys.
- 5083: Exceptional strength makes it ideal for marine use, though it requires specialized equipment for bending.
- Do the moving or rotating parts of the PBA machine need lubrication and what lubricant should be used?
The lead screw that moves back and forth needs to be lubricated, and the rotating ones are not used.
Just use a mixture of gear oil and butter.
