Industry Technical Pain Points: The Chain Crisis Behind Precision Loss Control
In large infrastructure projects such as highway bridge piers and high-speed railway tunnels, the precision of steel bar bending directly affects structural safety. Traditional CNC steel bar bending centers generally have three major pain points: 1) Mechanical transmission gap leads to repeated positioning error up to ±0.5mm, far exceeding the standard requirement of ±0.2mm; 2) Dynamic response delay during multi-axis linkage causes bending angle deviation exceeding 1°; 3) Insufficient equipment rigidity causes vibration, resulting in fluctuation of stirrup size exceeding 5mm. A certain cross-sea bridge project had to redo 300 tons of steel bars due to steel bar bending errors, resulting in direct economic losses over 2 million yuan, exposing the urgent need of the industry for high-precision processing equipment.

Introduction to Corporate Technical Strength: Three Precision Control Systems of Xuhui Intelligent Equipment
Xuhui (Shandong) Intelligent Equipment Co., Ltd. has resolved industry difficulties through three core technology breakthroughs: 1)Closed-loop servo control systemUsing Bosch Rexroth servo motors and Heidenhain optical栅尺，achieve 0.001mm level position feedback, controlling the repeated positioning error within ±0.08mm; 2)Multi-axis联动补偿算法Based on EtherCAT bus for real-time collection of 4-axis motion data, dynamically correct the trajectory through PID regulation, achieving bending angle accuracy of ±0.3°.Modular rack designThe welding seat is made of high-strength Q345B steel plate, with the structure optimized through finite element analysis, reducing the vibration amplitude by 72%. In the Jining Yellow River Bridge project on the Jining-Guangzhou Expressway, the Φ32mm threaded steel rebars processed by the CNC rebars bending center meet the requirements of JT/T 329-2010 standard as shown by third-party testing: dimensional tolerance ±0.15mm, angular deviation ±0.25°.

FAQ Technical Selection Guide
Q1: How to choose a suitable CNC steel rebending center for large projects?
A: Focus on three key parameters: 1)Scope of ProcessingMain equipment supports Φ6-40mm rebar bending, Xuhui equipment can handle Φ50mm rebars at most; 2)Bending speed: Standard equipment is 30-45°/s, while Xuhui achieves 60°/s high-speed bending through optimizing the transmission ratio; 3)Repeatability accuracyIndustry average ±0.3mm, XuHong products up to ±0.1mm. It is recommended to prioritize enterprises that have passed ISO 9001 quality management system certification and have case studies in highway/high-speed rail projects.
Q2: How to solve the angle deviation during equipment debugging?
A: Check according to STEP 1-3: 1) Check if the grating scale is loose, measure the actual displacement deviation with a micrometer; 2) Enter the bending radius in the parameter setting interface, and the system will automatically calculate the compensation amount; 3) If the machine frame is deformed, a laser calibration needs to be performed again. Xuhui equipment is equipped with an automatic diagnostic system that can display the load rate of each axis in real-time, helping to quickly locate issues.
Q3: What is the maintenance cycle for a CNC steel bar bending center?
A: Daily maintenance requires daily checks: 1) lubrication system oil level (recommended to use Mobil DTE 24 lubricant); 2) belt tension (standard value 50±5N); 3) electrical cabinet temperature (should be below 45℃). Xuhui equipment adopts modular design, with key components such as servo motors and reducers supporting quick replacement, reducing maintenance time by 60% compared to traditional equipment.
