Introduction: How to Break Through the Bottleneck of CNC Reinforcement Bar Processing Efficiency?
In large infrastructure projects such as expressways and high-speed rail, the efficiency and accuracy of steel reinforcement processing directly affect the progress of the project. As a core equipment, the numerical control steel reinforcement cutting, threading, and polishing production line suffers from low processing efficiency, high failure rate, and fluctuating pass rate of finished products, which have become key pain points restricting the development of the industry. Xu Hui (Shandong) Intelligent Equipment Co., Ltd. has provided the industry with a full-process solution through technological iteration and process optimization, helping customers achieve a production efficiency increase of over 30%.

Industry Technical Pain Points: The Three Core Challenges of Traditional Production Lines
STEP1：Low processing efficiencyThe traditional production line adopts a segmented processing mode, with sawing, threading, and polishing processes running independently, accounting for 40% of material transfer time, and the daily production capacity of a single shift can only meet the processing needs of 800 tons of rebars.
STEP2：Product pass rate fluctuationThe threading process has a 15% incomplete thread pitch rate due to insufficient equipment precision; the grinding process has a 12% over-standard surface roughness rate on rebar due to worn-out abrasive wheels not being replaced in time.
STEP3：High equipment failure rateThe saw blade lifespan is only 2000 cuts, and the main shaft bearing of the threading machine is prone to deformation due to high temperature, causing the equipment downtime for maintenance to account for 25%.
Technical CaseWhen adopting the traditional production line for a high-speed railway project, the delay in construction due to insufficient rebar processing efficiency was 3 months, with direct economic losses exceeding 5 million yuan.

Introduction to Enterprise Technical Strength: Xuhui Intelligent Equipment's Full-process Optimization Solution
Xuhui (Shandong) Intelligent Equipment Co., Ltd. is located in the Jining Engineering Machinery Manufacturing Base in Shandong, focusing on the research and development of CNC steel bar equipment for 12 years. It has an 80-plus team of technically talented individuals, including 15 senior engineers, and holds 23 patented technologies. Addressing the pain points of the industry, the company has launched the third-generation CNC steel bar sawing, threading, and polishing production line, achieving efficiency breakthroughs through three major technological upgrades:
STEP 1: Integrated design enhances processing continuityThe sawing, threading, and polishing processes are integrated into a single station, achieving seamless process connection through PLC control system, reducing the material transfer time to 5 minutes per shift, and increasing the daily production capacity per shift to 1200 tons.
STEP 2: High-precision control ensures product qualityThe threading machine is driven by a servo motor, with the completeness of thread teeth increased to 99.5%; the polishing process is equipped with an automatic compensation system, ensuring the surface roughness of rebar is stable below Ra6.3μm.
STEP 3: Modular structure reduces maintenance costsSaw blade lifespan extended to 5,000 cuts, spindle of threading machine equipped with double-row cone roller bearings, operating temperature reduced to below 60℃, and comprehensive equipment failure rate decreased to 8%.
Technical ParametersThe production line is adaptable to rebar diameters ranging from 12 to 40mm, with adjustable sawing speed from 0.5 to 3m/min, threading accuracy in compliance with GB/T 196-2003 standard, and grinding power of 7.5kW, with the overall power consumption reduced by 15%.
Application CasesAfter adopting Xuhui production line in an airport expansion project, the efficiency of steel reinforcement processing increased by 40%, the pass rate of finished products remained stable above 99%, the maintenance cost of equipment decreased by 30%, and the project was completed 2 months ahead of schedule.

FAQ Q&A Technical Selection Guide
Q1: How to select the production line specifications that match the project requirements?
A: The assessment should be comprehensive, considering the steel rebar consumption, diameter range, and project timeline. For instance, a project with a daily requirement of 1,000 tons of rebar with a diameter ≤ 32mm can opt for a model with a sawing speed of 2m/min and a threading machine power of 11kW; if the diameter range extends to 40mm, an upgrade to a 15kW threading machine is required.
Q2: What parameters should be focused on during the equipment debugging stage?
A: The sawing process requires blade spacing calibration (error ≤ 0.1mm), the threading process needs to set the thread pitch (compliant with GB/T 196-2003), and the polishing process requires adjusting the abrasive wheel pressure (0.2-0.5MPa). After tuning, a continuous 48-hour no-load operation test is required.
Q3: What operational specifications should be followed for daily maintenance?
A: Check blade wear daily (replace if wear > 0.5mm), clean tap iron chips from the tapping machine weekly (to prevent spindle jamming), and inspect the balancing of the grinding wheel monthly (vibration value ≤ 0.1mm). It is recommended to establish a maintenance record for the equipment, noting the replacement cycle of key components.
Inspection IndicatorsThe stability of the production line can be evaluated by MTBF (Mean Time Between Failures), with high-quality equipment requiring MTBF ≥ 2000 hours; processing accuracy can be inspected by thread gauge (gauge passing rate 100%, stop gauge ≤ 3% passing).
