Driven by the dual impetus of the continuous advancement of intelligent construction policies and the improvement of quality and efficiency in infrastructure projects, the CNC rebar cutting production line, as a core piece of equipment in the rebar processing field, is gradually replacing the traditional manual processing mode and has become a standard equipment for major projects such as high-speed railways, bridges, and urban rail transit. Integrating automation, intelligence, and high precision, this equipment has completely revolutionized the operation mode of rebar processing and provided key support for the industrial transformation of the construction industry.

The equipment adopts a high-precision servo drive system with full closed-loop control, combined with imported PLC and CNC control systems, to achieve precise control over the cutting process. The processing length accuracy can reach ±1mm, and the angle accuracy is controlled within ±1°, far exceeding the industry average. The innovative scissor-type inclined cutting edge design not only enhances cutting capacity — improving efficiency by 1/3 compared with equipment of the same tonnage — but also effectively reduces rebar deformation and ensures flat and uniform cutting edges. For rebars of different specifications, the equipment can cut multiple rebars simultaneously: it can cut 12 pieces of Φ12mm rebar at a time and 1 piece of Φ32mm rebar at a time, greatly improving the efficiency of batch processing.
Equipped with a high-performance hydraulic drive system, it has a maximum shearing force of up to 600KN and a shearing frequency of 20 times per minute. The maximum daily output within 8 hours can reach 9,666 pieces, which is 3-5 times more efficient than traditional processing equipment. It is equipped with a distributed oil injection system and an automatic lubrication system to ensure the long-term stable operation of the main machine head, controlling the equipment failure rate below 0.8%. The optimized pneumatic transmission design adopts stainless steel main pipelines, which reduces compressed air loss and enables faster response of solenoid valves, further enhancing the equipment's continuous operation capability.
Through precise parameter control and material optimization, the raw material loss rate is controlled within 5%, significantly reducing engineering material costs. The equipment uses low-energy-consuming motors and high-efficiency hydraulic systems: when cutting Φ25mm rebar, the working pressure only needs 15Mpa, reducing energy consumption by 40% compared with traditional equipment. At the same time, the noise is controlled below 75 decibels, complying with green construction standards.

It is equipped with an advanced human-machine interface, which can preset 100 types of processing parameters and support parameter memory and recall functions, realizing "foolproof operation" — operators can take up their posts after simple training. Some high-end models integrate IoT remote monitoring functions, which can real-time monitor the equipment's operating status and blade wear, and automatically compensate for cutting parameters to achieve predictive maintenance.
Adopting a modular combination design, it allows users to choose a single-bin or multi-bin material storage system according to actual needs. Combined with bidirectional material discharge and a movable raw material platform, it not only improves site utilization but also reduces labor intensity. The overall floor area of the equipment is approximately 27m×4m×2m. Meanwhile, it supports combination with a
CNC rebar bending center to form a cutting-bending linkage line, realizing integrated processing from raw materials to finished products.
It is equipped with an anti-jump automatic pressing device and a multi-level finished product storage mechanism, which effectively avoids safety hazards caused by rebar displacement during processing and comprehensively improves operation safety. The equipment has passed the ISO9001 quality management system certification; its core components adopt well-known domestic and foreign brands, and the application of imported seals further extends the equipment's service life, making its durability twice that of traditional models.
This production line is widely used in fields such as rebar processing and distribution centers, large bridge projects, high-speed railways, urban rail transit, water conservancy projects, and prefabricated buildings, and is particularly suitable for the cutting processing needs of large batches of bar rebars. In major projects such as the Yangtze River-to-Han River Water Diversion Project and the Huizhou-Zhaoqing Expressway, this equipment has achieved remarkable results: a 10% increase in production efficiency, a 68% reduction in labor costs, a total cost saving of over one million yuan for the projects, and a 100% qualified rate of finished products.
In response to different regions and engineering environments, the equipment can be customized to meet the needs of special working conditions such as plateaus and high temperatures, with an installation qualification rate of 100%. With the advancement of the "Belt and Road" Initiative, such equipment has been exported to many countries and regions, becoming an important representative of "Intelligent Manufacturing in China" going global.
A professional team provides full-process services from pre-sales model selection guidance and drawing review to installation and commissioning. For special situations such as limited site space, the equipment layout can be optimized to avoid installation rework. A nationwide service network and permanent service stations have been established, with a 24-hour service hotline opened. Fault reports are responded to within 15 minutes, general problems are solved within 2 hours, and on-site maintenance is provided within 24 hours for emergency situations. At the same time, comprehensive spare parts supply and equipment maintenance services are provided, significantly reducing customers' later operation costs.
Against the backdrop of the continuous expansion of the CNC rebar processing equipment market scale, the
CNC rebar cutting production line, with its core advantages of precision, efficiency, intelligence, and environmental protection, is becoming an important engine for the high-quality development of the construction industry. In the future, with the in-depth integration of AI technology and the Internet of Things, such equipment will be upgraded towards a more intelligent and flexible direction, providing better processing solutions for global infrastructure projects.
