Do you like this CNC rebar bending machine?

In traditional Chinese construction sites, rebar processing typically relies on manual labor, resulting in high work intensity and difficulty in ensuring precision. However, in recent years, the rise of intelligent systems and equipment has quietly changed this situation. A device called the "CNC rebar bending machine" is gaining popularity, winning favor with many construction units due to its improved processing efficiency, high precision, and ease of use. So, do the workers on the construction site actually like this equipment? Our reporter conducted an on-site investigation.

I. On-site Observation: From "Human Resources Dominance" to "Intelligent Assistance System" At a large construction site in the eastern part of the city, the reporter observed two CNC rebar bending machines in operation. After the operator, Mr. Li, simply entered the size and bending angle, the equipment automatically performed a series of actions including feeding, bending, and cutting. On average, it could produce dozens of rebar stirrups per minute, about five times faster than manual labor.

"Before, three or four of us would be busy all day, but now one person can operate the equipment, and the specifications are standardized with very few deviations," Mr. Li said with a smile. "This equipment is easy to use; even older workers can learn to operate it in half a day."

II. User Satisfaction: Reasons for Liking and Real Feelings Based on interviews with several on-site construction workers, foremen, and project managers, the reporter summarized several reasons why the CNC rebar bending machine is popular:

High Accuracy and Stable Performance: Traditional manual bending relies on the experience accumulated by skilled workers, but errors are prone to occur when they are fatigued. The CNC machine uses system control to ensure that each rebar stirrup is the same size, greatly improving the quality of prefabricated components and reducing material waste.

Reduced Labor Intensity and Improved Work Efficiency: "Before, my back would be aching after a day's work, but now I mainly monitor and adjust the parameters, which is much less physically demanding," said rebar worker Li Jianguo. This also makes it easier for construction sites to attract younger workers.

Improved Overall Construction Progress: Project manager Mr. Zhang calculated: "Although the equipment requires a significant initial investment, in the long run, it saves labor costs and shortens the production cycle, which is especially helpful for projects with tight deadlines."

Increased Safety: Automation reduces worker contact with rebar, reducing the risk of injuries such as crushing and cuts. Naturally, some master craftsmen mentioned that it takes time to adapt to the change from "manual operation to intellectual work," and that equipment maintenance requires professional skills, which may still pose a barrier for small and medium-sized construction sites in remote areas.

III. Industry Observation: Technological Popularization and Future Development Trends According to data from the China Construction Association, the average annual growth rate of the industry penetration rate of CNC steel bar processing equipment in China has been approximately 15% in the past three years, with steel bar bending machines being one of the most widely used categories. Several equipment manufacturers are promoting technological upgrades, such as adding Internet of Things (IoT) functions to achieve real-time monitoring and fault detection.

"Intelligent and eco-friendly systems are the new trends in the construction industry," emphasized Engineer Liu from a certain machinery research institute. "In the next step, CNC steel bar bending machines may be more deeply integrated with BIM (Building Information Modeling) systems to achieve automated digital processing."

IV. Reporter's Notes: Appreciation Comes from Real Value From the feedback from construction sites, the "appreciation" for CNC steel bar bending machines does not simply come from novelty, but rather from its ability to effectively solve the problems of traditional work – ensuring quality while freeing workers from tedious and repetitive tasks. This "appreciation" is actually a recognition of how technological progress promotes industry improvement. Of course, how to further reduce equipment costs and improve after-sales service, so that small and medium-sized construction sites can use and benefit from it, remains a topic that the entire industry chain needs to consider together.
