About PBA-CNC Aluminum Benders

Aluminum profile bending machines (also called aluminum benders) are used to form aluminum profiles.

An aluminum bender is the forming of aluminum profiles in one axis by a multi-roll bending machine. If the semi-finished product is not moved during the bending process, the distance between the rollers, their diameter, and the depth of immersion determine the bending radius. To produce particularly large bends, the material is pulled through the roller bending machine and moved alternately. The distance between the rollers is gradually adjusted.

In most cases, roll bending is the most flexible and cost-efficient bending method. A profile is guided between three adjustable bending rolls and gradually bent in the desired radius.

Roll bending is the ideal bending method for profiles with complex designs and different radii. BIT’s PBA CNC profile bending machine has become specialized in 3D aluminum profile bending machines.

Advantage of BIT CNC aluminum bender

Repeatability and accuracy: The first bend of the day is the same as the bend on the night shift. Servo electric gives you this every time.
Accurately controlled ‘Z’-axis: When forming non-symmetrical sections, able to control the twist of the section accurately.
Variable centers:
To get the most from a machine you should be able to get the widest capacity.
An operator should be able to learn to bend complicated bends in a single day. Bends with tangents, and multi-radius bends all should be formed easily and smoothly.

Features of PBA-CNC series aluminum bending machine


The steel plate is quenched and tempered, and each surface is a grind. After the combination, the upper and lower surfaces a grind, and the surface is electroplated with hard chromium.
The structure has high strength, good structural stability, and can withstand particularly large tensile forces.
The minimum spindle spacing is 100mm, and the minimum bending radius is 60mm


The secondary reducer is driven by the CNC servo motor, and the reducer drives the mold spindle to rotate through the universal drive shaft and the timing belt
With relatively large driving torque, it is suitable for bending various cross-section profiles.


Structure: The special speed reducer is driven by the CNC servo motor, and the special speed reducer drives the linearly movable speed reducer to realize the precise positioning of the intermediate spindle.
Advantages: The positioning accuracy (≤0.01mm) can be ensured when the spindle is moving forward and backward, and it is suitable for difficult variable-curvature arc machining.
The operation screen can be slid and rotated left and right (patent number: 2016+20865768.X), which facilitates the observation of the feeding and discharging process while operating.
The appearance of the machine is beautiful, the surface of the frame and the guard plate is pickled, phosphate, and electrostatic sprayed;

aluminum profile bending process


  • The profile is bent and formed at one time;
  • Bendable shapes: C shape, U shape, 3R shape, multi-segment arc program (two-dimensional variable curvature), etc.
  • Automatic calculation function of the rebound amount of the profile (the bending radius of the first profile is inaccurate, and the second profile can be bent accurately according to the calculation result)
aluminum profile bending process
  • Auxiliary calculation: knowing the chord length and chord height, the radius and arc length can be obtained
  • Self-diagnosis function: equipment failure can judge the quality of components
  • Manual adjustment function: inaccurate size arc can be corrected by manual function
  • The interface has the ability to switch between Chinese and English, and provide prompts and alarm information;
