2+2 Type Auto Copper Tube Decoiling Straightening Cutting machine
This 2+2 Type CNC
Pipe Straightening and Cutting Machine is a high-efficiency integrated Pipe Straightening and Cutting Machine dedicated to precision processing of various coiled metal tubes. It integrates automatic decoiling, high-precision straightening and fixed-length cutting in one, realizing one-stop processing of coiled tubes and meeting efficient standardized blanking demands for thin-walled metal tubes.
As a stable and reliable
CNC Tube Straightening-Cutting Combo Equipment, it adopts a professional 2+2 type straightening structure, which can effectively eliminate bending, distortion and internal stress of tubes, ensuring uniform straightness and high dimensional accuracy. Equipped with advanced tube chipless cutting technology, it cuts tubes smoothly without burrs and scraps, avoiding material waste and subsequent polishing and trimming procedures.
Driven by a high-performance servo system, this
Servo-Driven Tube Straightening & Flying Cut Machine runs stably with fast response speed and precise fixed-length control, adapting to continuous batch production efficiently. It is mainly used for precision cutting and processing of copper tubes, aluminum tubes and other metal pipes for air conditioners, water heaters and other refrigeration and heating equipment. With high automation, simple operation and stable performance, it effectively improves production efficiency and processing quality, making it an ideal equipment for pipe precision processing in related manufacturing fields.
