CNC rebar straightening and cutting machine

CNC rebar straightening and cutting machine integrates feeding, straightening, fixed‑length counting, and hydraulic cutting into a single unit. It delivers a maximum straightening speed of up to 100 m/min with cutting tolerance controlled within ±1 cm. It works with 4‑14 mm coiled round bars and deformed rebar. This automatic rebar processor fits continuous heavy‑duty production for construction‑site rebar workshops and steel‑bar distribution plants.

Our rebar straightening and cutting machine reduces labor requirements significantly. One worker can complete the whole production workflow single‑handedly. Meanwhile, it boosts dimensional accuracy for cut‑to‑length rebar. It addresses common pain points for rebar fabricators: low manual processing efficiency, large dimensional errors, and high labor costs.

machine Application Scenarios and Processable Materials

Processable Materials

• Coiled round steel and deformed rebar for construction purposes
• Various types of coiled cold‑drawn wire rods

Suitable Customer Scenarios

• Rebar processing sheds for housing construction, road & bridge, and tunnel construction sites
• Centralized rebar distribution processing plants and prefabricated component factories
• Small‑to‑medium‑sized steel bar processing workshops
• Processing enterprises requiring large‑volume fixed‑length cutting for coiled wire rods

rebar straightening and cutting machine Core Advantages

• CNC fixed‑length cutting, less material waste: Chromium‑molybdenum‑vanadium alloy metering wheel, cutting tolerance ±1 cm. Set length & quantity via CNC panel for uniform bar size, reducing scrap and improving threading & tying quality.
• Durable hydraulic cutting with smooth cuts: Premium hydraulic solenoid valve with aluminum body, copper coil and imported seals. Anti‑leakage for long‑time site operation, fast cutting response and minimal burrs.
• Simple & easy‑to‑learn operation: Stand‑alone CNC console with visualized parameters. Single‑person operation supported. Fault code alert and emergency stop enable quick troubleshooting.
• Multiple models for various production capacity: Straightening speed: 40‑100 m/min, for 4‑14 mm round steel & deformed rebar. Single‑traction / VF single‑traction / VF dual‑traction optional, plus optional 8‑m material rack, fit for small sites to large rebar factories.
• Heavy‑duty build for harsh site conditions: Thick welded frame, wear‑resistant alloy key parts. VF models adopt stepless speed regulation to reduce mechanical impact for long‑time continuous running.
• Multi‑purpose for higher utilization: Process coiled round steel, deformed rebar and cold‑drawn wire rods. One machine handles diverse processing orders.

CNC Rebar Straightening cutter Composition & Working Principle

Designed for dusty construction sites and long‑hour continuous operation, the rebar straightening and cutting machine is built with heavy‑duty wear‑resistant key components.

Main parts include optional 8‑meter material rack (prevent rebar tangling and jamming), straightening‑traction mechanism, chromium‑molybdenum‑vanadium alloy metering wheel, hydraulic cutting unit with premium solenoid valve, multi‑function CNC control console and thickened steel main frame.

1. Material feeding: Coiled rebar is placed on the material rack and automatically fed into the straightening mechanism by traction rollers.
2. Rebar straightening: Rebar passes through multiple straightening rollers to release internal stress and straighten the bent coiled material.
3. Real‑time length measurement: The chromium‑molybdenum‑vanadium alloy metering wheel tracks feeding length, and the CNC system compares it with preset values.
4. Fixed‑length hydraulic cutting: When the target length is reached, the solenoid valve activates the hydraulic cylinder for cutting; batch production quantity is configurable.
5. Finished‑product discharge: Cut‑to‑length rebar is discharged and stacked with uniform dimensions, ready for tying and threading.
6. Saved‑parameter reuse: Multiple sets of processing parameters can be stored. Switching rebar specifications only calls saved data without repeated mechanical adjustment.
