This fully automatic steel bar bending machine features a high-precision CNC system at its core, significantly improving upon the inefficiencies of traditional manual bending. It is specifically designed for large-scale projects like bridges and tunnels, accommodating carbon steel, rebar, and shaped steel with diameters of up to 60mm.
The machine operates at a high speed of 12 bends per minute, with an angle error of no more than 0.5°, making it ideal for a variety of molding requirements, including complex arcs and right angles.

rebar bender Machine usage scenarios
- The accurate bending of rebar and profiled steel takes just 20 seconds to complete a standard 90° bending hook, making it ideal for beam-column nodes, shear walls, and other large-scale construction sites, especially in ultra-high-rise and complex buildings.
- This equipment can also handle large curvature arch rebar and is capable of customizing bends for heavy components, such as those found in the main cable anchorage areas of suspension bridges and tunnel lining ring tendons.
- It features an adjustable baffle system that allows for quick switching between processing modes for straight threads, crescent ribs, and other shaped bars, which is essential for reinforcing road infrastructure.
- With its high-speed bending capability, the steel bar bending machine enables continuous production of prefabricated parts like pipe pile end plates and stacked plate truss bars, achieving a yield rate of up to 98%.
- By replacing different high-hardness molds, this steel bar bending machine can reliably produce special steel reinforcement components in S-shape and spiral shapes, which are commonly used in constructing shaped steel structures, such as stadium domes and supports for industrial equipment.
How does a Desktop CNC steel bar bender work?
The steel bar bending machine operates primarily by using a horizontal working disc that rotates around a vertical axis to bend the rebar. Here’s how it works:
Driven by a transmission mechanism
The motor sends power to the working disc via either belt or gear transmission, allowing for adjustments in the rotating speed and torque through a speed regulating device.
Center shaft and forming shaft alignment
The steel bar is positioned correctly on the working disc, and bending occurs in both directions by utilizing the alignment of the center pin and bending pin, along with the motor’s forward and reverse rotation.
Plastic deformation of the steel bar
As the steel bar experiences the pressure and friction from the molding axis, it gradually undergoes plastic deformation. This process ensures accurate and efficient bending of the steel bars through a precise transmission mechanism and mold interaction.
Additionally, to accommodate the bending requirements for rebar of various diameters, the working plate features multiple holes for inserting compression bending pins, allowing for the replacement of center pins of different sizes as needed.
