Product Description
Bar Cutting & Bending Machine: High-Precision CNC Rebar Processing Solution
Modern construction demands efficiency and precision that manual rebar processing simply cannot deliver. The bar cutting & bending machine from Shandong Zhongji Luyuan Machinery Co., Ltd. represents a breakthrough in intelligent steel reinforcement fabrication. This horizontal CNC steel bar bending center processes rebar ranging from φ12–50 mm with bending angles from 0–180° and lengths up to 12 meters.
Built on a fortified heavy-duty steel structure, this servo-driven framework accomplishes generation rates of 80–120 pieces per hour whereas keeping up bowing point blunders inside ±0.5° and length deviations beneath 1 mm. Fueled by an cleverly CNC touch control framework and upheld by 27.7kW add up to control (12kW/h genuine utilization), the machine conveys enterprise-grade execution for framework ventures worldwide.
Since 2016, with RMB 50 million in enlisted capital, our company has provided mechanized rebar handling arrangements to about 100 nations, collaborating with China Railroad, CRCC, CSCEC, and other industry leaders.
Why Choose Our Bar Cutting & Bending Machine
Unmatched Processing Efficiency
Your rebar fabrication facility needs equipment that maximizes output without sacrificing quality. Our double-head synchronous bending technology processes multiple bars simultaneously—up to 6 bars of φ12mm or 2 bars of φ25mm in a single cycle.
The servo-driven system operates at bending angular speeds of 48°–72°/s with moving speeds reaching 1m/s. This translates to consistent daily output that replaces 5–8 manual workers while reducing rebar waste by over 10%.
One operator can master the PLC touch screen interface within just 1 hour. Parameter storage functionality allows instant switching between different specifications without manual recalibration.
Precision Engineering for Critical Infrastructure
Bridge construction, nuclear power plants, and high-speed rail projects demand absolute accuracy. Our bar cutting & bending machine delivers bi-directional bending for φ10–32mm rebar and single bending for φ36–50mm bars.
The vertical bending design ensures dimensional consistency across thousands of pieces. Whether you're fabricating right angles, hooks, stirrups, or complex special-shaped reinforcements, each piece meets structural code requirements.
Minimum edge length starts at 80mm with a minimum bar length of 1250mm. Maximum edge dimensions reach 10,000mm, accommodating diverse project specifications from foundation work to superstructure assembly.
24-Hour Continuous Operation Capability
Your project timelines don't allow for equipment downtime. The heavy-duty machine body with servo drive system withstands 24-hour continuous stable operation without performance degradation.
The torsion-resistant structure maintains alignment during long-term use. Low failure rates and simplified maintenance protocols keep your production line running while minimizing service interruptions.
Total power consumption remains economical at 12kW/h actual usage despite the 27.7kW capacity, making it cost-effective for high-volume processing centers.

Key Performance Advantages
Intelligent Automation System
The PLC + touch screen control eliminates manual measurement errors. You can store unlimited processing parameters and recall them with one-key operation for repeat orders.
The system supports continuous automatic processing of multiple shapes and specifications. Safety protection systems include emergency stop functions, guard interlocks, and overload detection.
Superior Material Compatibility
Process both deformed bars and round bars from φ6–50mm diameter. The machine handles high-strength HRB500 grade rebar when equipped with high-torque motors and hardened alloy gears.
Cutting blades maintain HRC 55-60 Rockwell hardness for extended service life. High-quality four-sided blades perform 10,000+ cuts before rotation or replacement.
Space-Saving Vertical Design
The vertical bending configuration reduces your facility's footprint compared to traditional horizontal-only machines. This design particularly benefits urban processing centers where floor space commands premium costs.
Despite its compact orientation, the reinforced structure handles maximum-diameter bars without flexing or vibration issues.
Frequently Asked Questions
Q: How often should hydraulic oil be replaced in this machine?
A: Perform the first oil change after 100 working hours. Subsequent changes should occur every 1,500–2,000 hours depending on environmental dust levels. Use ISO VG 46 hydraulic oil for optimal performance.
Q: Can this machine process HRB500 grade high-tensile rebar?
A: Yes, the machine handles HRB500 grade steel when configured with high-torque motors and hardened alloy gears specifically rated for high-tensile materials. Confirm your requirements at order time.
Q: What causes inconsistent bending angles during operation?
A: Inconsistent angles typically result from loose limit switches or worn bending bushings. Regular calibration and lubrication of the rotating disk resolve most accuracy issues. Check these components during routine maintenance.
Q: What is the expected lifespan of the cutting blades?
A: Under standard conditions with proper maintenance, cutting blades perform 10,000+ cuts before requiring rotation. Four-sided blade design allows rotation to fresh cutting edges, extending total lifespan to 40,000+ cuts.
Q: Can the machine operate in outdoor or high-humidity environments?
A: The mechanical components are robust, but the electrical cabinet requires IP55 rating or higher. We recommend protective shelters for rainy conditions to prevent electrical short circuits and extend component life.
Q: How many operators does this equipment require?
A: Only one operator is needed for full operation. The intuitive interface and automated feeding systems eliminate the need for multiple personnel. New operators become proficient within 1 hour of training.
Q: What quality control tests ensure machine reliability?
A: Each unit undergoes 8-hour continuous load testing, angle accuracy verification (ensuring ±0.5° tolerance), maximum diameter shearing tests, hydraulic pressure stability tests, and electrical insulation resistance checks before shipment.
Q: Is technical support available internationally?
A: Yes, our professional after-sales team provides technical assistance across nearly 100 export markets. Remote diagnostics, video support, and on-site service are available depending on your location.
