Revolutionize your steel bar processing with the Automatic 4-12 mm CNC Steel Bending Machine—a versatile, high-precision solution designed for automated fabrication of stirrups, hook bars, and plate bars in diameters ranging from 4mm to 12mm. Engineered for efficiency and precision, this CNC-powered machine is ideal for railways, highways, bridges, airports, housing construction, and steel processing plants, delivering consistent results for projects of all scales.
Perfect for diverse construction and fabrication needs, this machine excels in:
Infrastructure Projects: Producing stirrups and reinforcements for railway tracks, highway bridges, and airport runways
Residential & Commercial Construction: Forming hooks and hoops for concrete slabs, columns, and foundation systems
Steel Fabrication Plants: Mass-producing standardized or custom-shaped bars for precast elements and structural components
Its adaptability makes it a critical asset for any project requiring precise, repeatable steel bar bending.
As a fully automatic CNC steel bar hoop bending machine, it streamlines the production of intricate shapes:
Stirrups: Create closed or open loops in square, rectangular, or diamond profiles
Hook Bars: Form 90°/135°/180° hooks for structural connections
Plate Bars: Bend flat bars into custom angles for architectural or industrial applications
The machine’s advanced control system supports multi-step bending sequences, allowing operators to program complex shapes with ease, reducing reliance on manual labor and minimizing errors.
Processes 4-12mm diameter steel bars (including mild steel, ribbed rebars, and alloy variants), catering to most standard construction requirements. For heavier-duty needs, it can also handle 14-16mm bars with optional upgrades, ensuring flexibility for specialized projects.
Incorporates curve straightening mechanism for pre-processing raw bars, eliminating kinks and ensuring straightness before bending. This feature enhances material consistency, reduces waste, and improves the accuracy of final components.
The magnetic feeding system (under development) will further automate material handling, providing precise, contactless positioning for bars. Currently, the machine uses the automatic step feeding function to advance bars incrementally, ensuring consistent length and spacing for repeated bending tasks—ideal for high-volume production.
CNC Precision: Achieves bending angles with ±1° accuracy and length tolerance within ±2mm, meeting international standards (e.g., ASTM, BS).
User-Friendly Interface: Intuitive touchscreen allows quick programming of bend sequences, storage of 100+ custom templates, and real-time production monitoring.
Durable Construction: Heavy-duty steel frame and corrosion-resistant components ensure reliable operation in harsh workshop environments.
Energy Efficiency: Low-power servo motors reduce energy consumption by 30% compared to traditional hydraulic systems.
✅ Time Savings: Automates 80% of the bending process, cutting production time by half
✅ Cost Efficiency: Reduces material waste by 20% and labor costs through minimal manual intervention
✅ Precision Assurance: Curve straightening and CNC control deliver uniform, high-quality results
✅ Scalability: Handles both small-batch custom orders and large-scale production runs
Whether you’re a contractor working on a high-rise or a fabricator specializing in precast elements, the Automatic 4-12 mm CNC Steel Bending Machine delivers the speed, precision, and reliability needed to stay competitive.
