NC50 bender for bending large diameter, the bending angle can be adjusted 0 ° -180 bending radius 20-450m / m. 10HP motor and uses a 6-inch grayscale touch screen, high-efficiency operation is extremely simple PLC architecture program can store up to 200 groups each program can be set to 20 different angles into the bend angle using the encoder (ENCODER), precision ± 0.1 degrees guided modes including auxiliary push function, along with the repeated advance and retreat guided mode function enables to shorten the length and reduce interference. SSR control components using high-performance, increase the mechanical stability. An external modem, software upgrades and data lines can show Hao mechanical condition, to facilitate future maintenance work can be set to a variety of angles to contact each other take turns bending, while omitting handling trouble. Data can be stored more than two years, and to make data storage plus battery longer.
