Industry Technical Pain Points: The Efficiency and Precision Dilemma of Traditional Reinforcement Bar Processing
In large infrastructure projects such as highways and high-speed railways, the efficiency and accuracy of steel bar processing directly affect the progress and quality of the project. Traditional steel bar sawing, threading, and polishing processes rely on manual operations, and there are three core pain points:
STEP 1: Inefficient——Single-process independent operation, time-consuming in manual handling and clamping, the processing cycle for a single steel bar can last up to 8-10 minutes, difficult to meet the needs of large-scale construction.
STEP 2: Insufficient Precision——Manual measurement and operation errors cause the threading length deviation to exceed ±1mm, the surface roughness after polishing exceeds the standard, affecting the strength of steel bar connections and the quality of concrete pouring.
STEP 3: Rising Costs—— Multi-process decentralized operations require several operators, with labor costs accounting for over 30% of the total processing costs, and the equipment occupies a large area, resulting in low site utilization.
A bridge-tunnel project was returned due to insufficient precision in steel bar threading, resulting in a delay of 15 days and direct economic losses exceeding 2 million yuan, highlighting the limitations of traditional processing modes.

STEP 2: High-precision control——Utilizing laser positioning and servo motor driving technology, the threading length deviation is controlled within ±0.2mm, and the surface roughness is achieved at Ra3.2μm, meeting the GB/T 1499.2-2018 standard.
STEP 3: Intelligent ManagementEquipped with a production data collection system, it can monitor the equipment operation status and processing parameters in real-time, support remote fault diagnosis and parameter optimization, and reduce manual intervention.
This production line has been applied in an airport expansion project, processing 200 tons of rebars daily, saving 40% of labor costs compared to traditional technology, and improving product pass rate to 99.5%, receiving high praise from customers for its "efficient, accurate, and stable" performance.

FAQ: Technical Selection Guide for CNC Steel Bar Sawing, Thread Rolling, and Polishing Production Line
Q1: How to select the suitable equipment model for the project scale?
A: Xuhui production line offers various specifications, with the small model (sawing length 1-6m) suitable for standardized steel bar processing and distribution centers, the medium model (6-12m) for high-speed railway and airport projects, and the large model (12-18m) for ultra-long steel bar processing such as cross-sea bridges. Selection should be based on the daily processing volume of the project (e.g., below 50 tons for the small model, 50-150 tons for the medium model, and above 150 tons for the large model) and site conditions (equipment footprint of about 20-50㎡).
Q2: What are the requirements for raw materials of the equipment?
A: Supports hot-rolled ribbed steel bars (HRB400, HRB500) and cold-rolled ribbed steel bars (CRB550, CRB600H), diameter range 12-40mm. Raw materials must be free of severe rust and bending, otherwise it may affect sawing accuracy and threading quality. It is recommended to equip with Xuhui's independently developed rebars straightening machine for pre-treatment.
Q3: How to ensure long-term stable operation of the equipment?
A: Xuhui offers a "3+2" service guarantee: 3 years of full machine warranty, free replacement of consumables (such as saw blades, threading dies) within 2 years; regular on-site maintenance by technicians, and operation training services. Key components of the equipment (such as servo motors, PLC) use international brands like Siemens, Schneider, with a failure rate below 0.5%.
