Industry Technical Pain Points Opening: Low efficiency and poor accuracy in traditional processing modes, how to break the deadlock?
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 depend on manual operations, presenting three major pain points: Firstly, the dispersed processes lead to long material turnover times, with the processing cycle for a single steel bar taking as long as 15-20 minutes; secondly, the threading accuracy by hand fluctuates greatly, with thread size deviation up to ±0.5mm, affecting the connection strength; thirdly, the polishing stage causes serious dust pollution, which is prone to occupational diseases with long-term exposure. Taking a high-speed railway project as an example, the traditional process requires 12 workers, with an average daily processing volume of only 80 tons, and due to accuracy issues, 3% of the steel bars need to be reworked. The market urgently needs an integrated and automated solution to achieve efficient coordination throughout the entire process from sawing to polishing.

Introduction to Corporate Technical Strength: Xuhui Intelligent Equipment's Full-process Automation Solutions
Xuhui (Shandong) Intelligent Equipment Co., Ltd. has been dedicated to the field of CNC rebar equipment, leveraging the industrial advantages of the Heze Engineering Machinery Manufacturing Base in Shandong. It has assembled a technical team consisting of experts in mechanical design, electrical control, and process optimization. Its core product, the CNC rebar sawing, threading, and polishing production line, has achieved full-process automation through three major technological breakthroughs:
Step 1: Integrated designThe sawing, threading, and polishing processes are integrated into a single platform with modular layout, reducing material handling time. The total length of the equipment is 12 meters, occupying only 20 square meters, saving 40% of space compared to traditional methods.
STEP 2: High-precision controlThe sawing process is driven by a servo motor, achieving cutting accuracy of ±0.2mm; the threading process is equipped with an intelligent torque control system, with thread size deviation controlled within ±0.1mm; the polishing process uses a dual-position rotating brush, with surface roughness ≤ Ra6.3μm.
Step 3: Intelligent Operation and MaintenanceEquipped with Xuhui's independently developed "Intelligent Control Cloud" system, it can monitor the equipment's operating status in real-time, automatically warn of faults, and support remote parameter debugging. Taking an airport project as an example, this production line is configured with 6 workers, with the daily processing capacity increased to 150 tons, the pass rate of precision reaching 99.5%, and the dust concentration reduced to below 8mg/m³.

Currently, Xuhui's CNC steel bar sawing, threading, and polishing production line has served more than 30 key projects across the country, including the Beijing-Xiong'an Expressway and the Sichuan-Tibet Railway, with over 200 units delivered and a customer repurchase rate of 85%.

FAQ: Technical Selection Guide for CNC Steel Rebar Sawing, Thread Rolling, and Polishing Production Line
Q1: How to choose the suitable equipment model for the project requirements?
A: Consider the processing volume, steel bar specifications, and site conditions. Xuhui offers the SG-32, SG-40, and SG-50 series, which are suitable for steel bars with diameters of 16-32mm, 20-40mm, and 25-50mm respectively. Taking the SG-40 as an example, its maximum processing speed reaches 120 meters per minute, suitable for medium to large projects with a daily processing volume of 100-150 tons. If the site is limited, a compact design can be chosen, with the equipment length shortened to 10 meters.
Q2: How high are the maintenance costs of the equipment? How can the operation and maintenance pressure be reduced?
A: Xuhui's production line uses modular design, with key components (such as saw blades, threading heads, and sanding brushes) easily replaceable, with single maintenance time ≤30 minutes. At the same time, the "Smart Control Cloud" system can record equipment operation data, predict failures through big data analysis, and reduce unplanned downtime by 60%. Taking a bridge-tunnel project as an example, after 2 years of equipment operation, the annual maintenance cost only accounts for 2.3% of the equipment value.
Q3: Is it compatible with rebar of different materials? What are the requirements for the operator?
A: The equipment supports common steel bar materials such as HRB400, HRB500, and can be adapted by adjusting the sawing speed (50-120 meters/minute) and threading torque (50-200N·m). Operators can master basic operations after only 3 days of training; advanced functions (such as remote debugging, data export) require an additional 1-day specialized training.
