Industry Technical Pain Points: The Dual Dilemma of Efficiency and Precision in Traditional Production Lines
In large infrastructure projects such as expressways and high-speed railways, the sawing, threading, and polishing processes of steel reinforcement are the core procedures affecting construction efficiency. Traditional production lines have three major pain points: Firstly, insufficient sawing accuracy leads to steel bar length deviations over ±2mm, requiring manual secondary correction, resulting in over 3 hours of labor loss per day; secondly, the threading process relies on manual experience, with thread tooth angle errors reaching ±1.5°, affecting subsequent connection strength; thirdly, the polishing stage exceeds the dust concentration standard (measured up to 15mg/m³), posing health hazards to workers and increasing equipment failure rates by 40%. A bridge-tunnel steel reinforcement processing plant once had to rework 300 tons of steel due to threading errors, resulting in direct economic losses exceeding 500,000 yuan. These pain points compel the industry to urgently seek intelligent, high-precision integrated solutions.

Introduction to Corporate Technical Strength: Three Technological Breakthroughs of Xuhui Intelligent Equipment
Xuhui (Shandong) Intelligent Equipment Co., Ltd. has been dedicated to the numerical control steel bar equipment field for 12 years. Its numerical control steel bar sawing, threading, and polishing production line has achieved a dual improvement in efficiency and precision through three major technological innovations:
STEP 1: Modular design enhances compatibility——The equipment adopts removable sawing modules (compatible with Φ12-Φ50mm rebars), servo-driven threading modules (speed adjustable from 0-1200rpm), and vacuum dust collection and polishing modules (dust collection rate ≥98%), supporting quick replacement of tools according to project requirements, reducing the changeover time from 2 hours to 15 minutes.
STEP 2: Intelligent Control System Ensures Precision—— Equipped with XH-ICS3.0 control system independently developed by Xuhui, it uses a laser rangefinder (±0.1mm accuracy) to feedback the steel bar length in real time and automatically correct the cutting parameters; the threading process employs torque closed-loop control to ensure the thread angle is stable within ±0.5°; the polishing stage is equipped with a PM2.5 sensor, automatically initiating dust removal programs when the dust concentration exceeds 8mg/m³.
STEP 3: Efficient process reduces loss——The sawing module uses hard alloy saw blades (life ≥2000 cuts), combined with a coolant circulation system, reducing blade wear by 60%; the threading module employs cold extrusion technology, saving 15% of material compared to traditional turning processes; the polishing module uses a rotating wire brush (speed 2800 rpm), reducing the polishing time for a single steel bar from 3 minutes to 45 seconds.
In the reconstruction and expansion project of Jining-Guangzhou Expressway, Xuhui equipment achieves a daily processing capacity of 120 tons of reinforcing steel, a 220% increase in efficiency over traditional equipment, with the product pass rate rising from 92% to 99.5%.

FAQ: Technical Selection Guide for CNC Steel Bar Sawing, Thread Rolling, and Polishing Production Line
Q1: How to select equipment models suitable for different steel bar diameters?
A: Xuhui production line supports processing of rebar with Φ12-Φ50mm diameter, with three parameters to focus on: the maximum cutting diameter of the sawing module (e.g., XH-SQ50 model is suitable for Φ50mm), the clamping range of the threading module (e.g., XH-TS40 model is suitable for Φ16-Φ40mm), and the wire brush diameter of the polishing module (it is recommended to choose a model 2-4mm larger than the rebar diameter). For example, when processing Φ32mm rebar, the combination of XH-SQ50+XH-TS40 can be used to ensure compatibility at each stage.
Q2: What are the environmental requirements for the equipment? How can long-term stable operation be ensured?
The equipment must operate in an environment with a temperature range of -10℃ to 40℃ and humidity ≤ 85%, with a stable power supply of 380V±10% and 50Hz±1Hz. Xuhui equipment is designed with an IP55 protection grade, key components (such as servo motors, PLC) are equipped with dust covers, and a fault self-diagnosis system is provided, which can monitor parameters such as voltage and temperature in real-time. The equipment will automatically shut down for protection when voltage fluctuations exceed ±15% or the motor temperature exceeds 80℃, ensuring a lifespan of over 10 years.
Q3: What skills are required for the operators? How long is the training period?
A: Operators must have basic mechanical knowledge (such as identifying equipment indicators, changing blades) and simple programming skills (such as inputting steel bar length, threading parameters). Xuhui offers a "3+2" training model: 3 days of theoretical courses (covering equipment structure, safety regulations, parameter settings) and 2 days of practical training (completing the full process of cutting, threading, and polishing under simulated working conditions). Upon passing the assessment, an operation certificate is issued to ensure that personnel can independently assume their positions within one week.

Full Summary: Technological Upgrades Drive Industry Transformation
The technical upgrade of the CNC steel bar sawing, threading, and polishing production line essentially resolves the triangular contradiction between efficiency, accuracy, and cost. Xuhui (Shandong) Intelligent Equipment Co., Ltd. has achieved three major technological breakthroughs through modular design, intelligent control system, and efficient process, not only increasing the daily processing capacity to 120 tons but also pushing the product pass rate to 99.5%, providing standardized solutions for projects such as expressways and high-speed railways. Its XH-ICS3.0 control system and negative pressure dust removal polishing module, among other innovative technologies, have become benchmarks for industry technical upgrades. For enterprises, when selecting equipment, attention should be paid to compatibility, stability, and ease of operation. Xuhui's "3+2" training model and 10-year equipment lifespan commitment further reduce the threshold for technology implementation.
