PRODUCT DETAILS



The CNC stirrup bender features an advanced straightening system with a unique curved mechanism that processes ribbed bars without surface damage. Its vertical design allows independent adjustment for each steel bar, ensuring precise alignment while preventing twisting. The high-performance alloy steel rollers offer exceptional wear resistance for long-lasting operation.  


For bending accuracy, the machine incorporates precision forming control near the corner section, guaranteeing consistent angle quality. This intelligent design maintains tight tolerances while handling various reinforcement shapes, from standard stirrups to complex custom configurations. The combination of robust construction and smart processing ensures efficient, high-quality output.

FAQ


1. What shapes can your CNC stirrup bender produce?

Our machine can fabricate rectangular, square, circular, polygonal (triangle to octagon), spiral, seismic hooks (135°/180°), 3D trusses, and custom curves (parabolic, involute, etc.).


2. What is the accuracy of your machine?

We guarantee ±0.5° bending angle precision and ±1mm dimensional tolerance, ensuring high-quality reinforcement every time.


3. What rebar sizes can the machine handle?

It processes Ø4mm to Ø16mm (or larger, depending on model)—both plain and ribbed steel bars.


4. How fast is production compared to manual bending?

Our CNC bender is 5–10x faster, producing up to 1,500–2,000 stirrups/hour (varies by shape/size).


5. Can it integrate with BIM/CAD software?

Yes! The machine supports CAD/CAM file imports (DXF, DWG) and is BIM-compatible for seamless workflow integration.


6. What maintenance does the machine require?

Minimal upkeep: daily cleaning, weekly lubrication, and monthly servo system checks (full guidelines provided).


7. Do you offer training and technical support?

We provide on-site/remote training, 24/7 technical support, and detailed operation manuals.


8. What’s the ROI (Return on Investment) period?

Most clients recover costs within 6–12 months due to labor savings, reduced material waste, and boosted productivity.
