A CNC stirrup bending machine is a piece of automated equipment that processes steel rebar into closed-loop shapes. These shapes, known as stirrups, hold concrete columns and beams together. This machine straightens the incoming wire, bends it to the required angle, and cuts it to length—all in one cycle. It runs on pre-set programs, so every piece matches the design. Manual bending cannot match this speed or repeatability. This equipment handles round steel and deformed steel bars (ribbed bars) without changing the setup.
The table below lists technical data for four models: YG-1, YG-2, YG-3, and YG-4. Buyers should match the wire diameter and power to their daily output needs.
This equipment offers clear advantages over older manual methods.
Accurate Bending Every Time:The CNC system controls both the feeding length and the bending angle. With ±1 mm length tolerance and ±1° angle tolerance, the finished stirrups fit perfectly into formwork. There are no rejects caused by human tiredness.
High Output with Less Labor:One person can run the machine. The automatic cycle straightens, bends, and cuts without stopping. For YG-3, the bending speed reaches 1000° per second, which means hundreds of pieces per hour. This output often replaces 8 to 12 manual workers on site.
Works with Two Wires at Once:Many models support double-wire processing. This feature doubles production in the same time. For example, YG-2 processes two 8 mm round bars simultaneously. That is a direct way to lower per-piece costs.
Simple Operation and Low Maintenance:The touchscreen stores common shapes. Operators pick the pattern, and the machine handles the rest. The cutting system uses durable mechanical blades. Only these blades need periodic change. No complex hydraulic oil changes or filter replacements are required.
For projects that need closed hoops, this unit works as a reliable rebar hoop bender. It also serves as a cnc hoop bending machine for round or polygonal shapes. Users often call it a CNC steel bar hoop bending machine when producing large-diameter rings for pipes or culverts. The same machine changes from squares to diamonds to polygons with just a few screen taps.
Q: What is the difference between single-wire and double-wire processing?
A: Single-wire processes one rebar at a time. Double-wire processes two rebars side by side. Double-wire doubles your output per hour but requires smaller diameters (up to 10 mm round or 10 mm deformed).
Q: Does this machine work with ribbed (deformed) steel?
A: Yes. The straightening rollers and bending head handle deformed bars without damaging the ribs. Just select the correct diameter range for your model.
Q: How accurate is the cut length?
A: All four models hold length to ±1 mm. This meets standard construction tolerances for reinforcement placement.
Q: What power supply is needed?
A: These machines run on standard 380V, 3‑phase, 50 Hz. Total power ranges from 14 kW to 32 kW. Check your local supply before purchase.
Q: What shapes can it produce?
A: Squares, rectangles, triangles, diamonds, pentagons, polygons, and custom closed shapes. The control system stores up to 200 different patterns.
Q: How many workers are needed?
A: One operator is enough. The machine feeds, bends, cuts, and ejects the finished part automatically.
Q: Can I get a price for a specific model?
A: Yes. The price depends on the model and optional accessories like extra pins or custom tooling. Contact us with your diameter and output requirements for an exact quote.
