8 axis CNC spring machine has 8 sets of servo motors, completely abandoned the traditional 5 axis CAM reducing mechanism whose operation is cumbersome, and use the CNC system directly control the spring diameter and reducing diameter, new workers easy to learn and easy to understand. When coil spring with large diameter variation, the control system can set any changes of the angle between two coiling pin and automatically follow the most reasonable vertex positions of the coiling circle with different sizes, to ensure the circle size precision, new workers easy to learn and easy to understand. The assist mandrel mechanism adopts the hydraulic locking function, and it is fixed by the hydraulic jacking after lifting, which is easy to operate, with small vibration and high incision precision; The functions of straight cut, subtend cut, swing cut, twist cut are complete; Wire feeding mechanism has two speed transmission which are high speed and low speed; The control system matches the remote Internet interface, and the software has a graphical automatic programming template. After inputting the required value, the system will automatically generate a spring program, and the required coiled spring can be completed by slight modification. The machine can be equipped with imaging measuring instrument.
