The CNC Rebar Cutting, Threading and Polishing Production Line is an automatic integrated equipment integrating cutting, threading and polishing, specially designed for rebar end processing in construction projects. It is suitable for common specifications of rebars such as deformed steel bars and round steel bars with a diameter of 12-50mm. The equipment adopts full CNC intelligent control, which can realize integrated operations of automatic rebar feeding, precise cutting, efficient threading and fine polishing, without manual intervention in the connection of each process. It integrates auxiliary functions such as fault self-inspection, finished product sorting and waste collection. It is easy to operate and efficient in processing, widely used in infrastructure projects such as high-rise buildings, highway bridges, municipal engineering and large workshops. It can greatly improve the efficiency and quality of rebar end processing, replace the traditional segmented manual processing mode, reduce labor input and processing losses, and ensure the consistency and standardization of batch processing.
