Product Description

Product Description

Rotating Roller CNC Rebar Straightening & Cutting Line

Production Line Features

1. Rotary Straightening Principle
Uses rotating rollers for dynamic straightening, effectively reducing internal stress and maintaining rebar surface integrity.

2. High Cutting Accuracy
Cutting error is as low as ±1.5 mm, meeting strict dimensional requirements.

3. Digital Frequency Conversion Drive
Combines frequency motor, hard-tooth reducer, and inverter for low noise, precise speed control, and stable performance.

4. Servo + PLC Control System
Ensures high efficiency, low energy consumption, and accurate cutting length with minimal manual input.

5. Non-Stop Production Design
CNC buffer discharge rack supports continuous feeding and automatic packaging, improving productivity and reducing labor and space costs.

6. Wide Material Compatibility
Suitable for high-strength rebar (e.g., CRB600H), ribbed rebar, and special-shaped rebar.

Raw Material

Finished Product

Compatible with your local rebar grades

Diameters ranging from 3mm-12 mm.

(Provide the rebar grades used in your country)

Cutting length customized according to your needs

Main Applications:

1. High-Precision Components: export-grade precast elements
2. Welded Mesh Production: fine rebar mesh for walls and slabs
3. Urban Construction: noise-sensitive city centers and residential zones
4. Export Markets: EU, Middle East, Singapore, and other high-standard regions
5. Fine Rebar Processing: 3–12 mm bars for delicate structures
Key Advantages:

1. Ultra-High Accuracy: ±1.5mm cutting precision meets strict international standards
2. Gentle on Rebar: rotating rollers protect ribs – ideal for CRB600H
3. Fine Diameter Expert: specially designed for 3–12 mm thin bars
4. Low Noise Operation: gearbox-free design reduces noise for urban sites
5. Continuous Production: fully automated with CNC stacking and intelligent control

The complete production line consists of the following units:
 
Rotary decoiler, anti-twist cage, rotary CNC high-speed straightening and cutting machine, automatic alignment discharge rack, frequency conversion servo control system.

1. Rotary Decoiler
Ensures smooth and stable rebar coil feeding.

2. Anti-Twist Cage
Prevents rebar from twisting during the feeding process.

3. Rotary CNC High-Speed Straightening & Cutting Machine
Straightens and cuts rebar with high precision and speed.

4. Automatic Alignment Discharge Rack
Automatically collects and aligns finished rebar for easy handling.

5. Frequency Conversion Servo Control System
Controls speed and cutting length with high accuracy and efficiency.
