CNC Rebar Cutting, Threading and Polishing Production Line: An Intensive Intelligent Equipment for Rebar Processing in Infrastructure Construction

The CNC Rebar Cutting, Threading and Polishing Production Line developed by Shandong Zhongji Luyuan Machinery is an integrated equipment specifically designed to address the pain points of "low efficiency, poor precision and heavy pollution" in traditional rebar processing. This production line integrates three core processes of "cutting, threading and polishing", and realizes full-process automated operation through a CNC system. It has been applied in key projects such as the reconstruction and expansion of Ji-Qing Expressway and Jinan Metro Line 6, becoming a core equipment for infrastructure projects to reduce costs, improve efficiency and enhance processing standardization.

I. Core Advantages: Solving Four Major Pain Points of Traditional Processing

1. Efficiency Leap: 4-Fold Capacity Increase, 60% Reduction in Labor Costs

• Traditional processing: For ribbed steel bars with a diameter of 25mm, 3 workers are required to operate in division of labor, and the per capita daily processing volume is less than 1.5 tons;

• Production line processing: Only 2 workers (1 main operator + 1 assistant) are needed, and it can process 30-35 tons of ribbed steel bars with a diameter of 20-32mm per day (8 hours). The efficiency is increased by 4 times, the labor cost is directly reduced by more than 60%, and the manual transfer link between processes is reduced, shortening the processing cycle.

2. Strict Precision Control: 99.8% Qualification Rate, Meeting National Standards

• The cutting precision reaches ±1mm, far exceeding the ±3mm error standard of traditional manual work, and the rebar length consistency is higher;

• The threading adopts a rolling process, and the fullness of the thread profile and taper comply with the standard of GB/T 1499.2-2018 Steel for Reinforced Concrete. The qualification rate is stably maintained at 99.8% through third-party testing;

• The polishing link uses the linkage of multiple sets of wire wheels, so that the ends of rebars are free of burrs, avoiding installation deviations in subsequent connections, and the rework rate is reduced from 12% (traditional) to 0.2%.

3. Green and Safe: Low Noise and Dust-Free, Conforming to Modern Construction Standards

• It adopts low-noise motors and shock-absorbing structures, and the operating noise is controlled below 75 decibels, which is lower than the workshop noise limit;

• Key parts are equipped with infrared safety light curtains and emergency stop buttons. When operators approach dangerous areas, the equipment automatically shuts down, achieving zero risk of mechanical injury.

4. Low-Cost Operation and Maintenance: Modular Design, 30% Reduction in Maintenance Costs

Adopting a modular structure layout, core components (such as cutting mechanisms and threading dies) have strong versatility, and daily maintenance does not require a professional team; at the same time, the energy consumption design is optimized, saving 18% more electricity than similar equipment. The later maintenance cost is 30% lower than the industry average, and the cost-effectiveness of long-term use is significant.

II. Technical Parameters: Covering Mainstream Infrastructure Processing Needs

III. Application Scenarios: Adaptable to All Infrastructure Fields

• Transportation Engineering: Processing of pile foundation rebars and support rebars for highway/railway bridges and subway tunnels, adapting to different diameter and length requirements;

• Housing Construction Engineering: Processing of load-bearing rebars for high-rise building foundations and shear walls, ensuring the precision of thread connection;

• Water Conservancy Engineering: Processing of foundation rebars for reservoir dams and water transmission pipelines, adapting to complex outdoor operating environments;

• Municipal Engineering: Processing of structural rebars for comprehensive pipe corridors and urban viaducts, meeting the needs of intensive construction.

IV. Service Support: Full-Cycle Guarantee for Commissioning

• Customized Adaptation: Adjust the production line parameters and layout according to the project's rebar specifications and production capacity requirements;

• On-Site Commissioning: After the equipment is delivered, engineers will conduct on-site installation and commissioning to ensure commissioning within 24 hours;

• Specialized Training: Provide training on CNC systems, safe operation and daily maintenance for operators, and operators can take up their posts only after passing the assessment;

• After-Sales Response: 24-hour online after-sales service, with fault diagnosis responded to within 1 hour and core components replaced within 48 hours.
