High speed rotary punching machine is a new developed punching machine, which can punch the metal sheet with high speed, which can reach 80-100 meters per minute.The structural of the meatl rotary punching machine is there are up rollers and down rollers with teeth and notching, high rotary running and punching. Holes diameter, holes center distance, holes shapes, it is determined by the rotary rollers molds.

HIgh speed rotary punching machine can be designed according to the requirements, such as the raw material steel strips width, thickness, holes pattern, holes center distance. Below i can introduce you a rotary punching line which designed to make the hoop iron. Whole line of rotary punching machine is including below parts: un-coiler, leveling, rotary punching, cut to legnth, receiving table or re-coiler.

Below are some specifications and pictures of the whole machine line, please check it. if you have any need of the rotary punching machine, please write me your requirements, we can design your perfect rotary punching line.
