SFI-8120 JS-Z51K-12-8
CNC Spring Making Machine SFI-8120

Optimized for large spring diameters

  • 8-axis CNC system with 8 servo motors replaces traditional cam mechanisms.
  • CNC-controlled spring diameter and reducing diameter for easy setup.
  • Automatic calculation of coiling pin angle for stable circular precision.
  • Hydraulic locking on the auxiliary core cutter for low vibration and high precision.
  • Supports straight, subtend, swing, and twist cutting functions.

Machine Features

Details extracted from the provided SFI-8120 image.

The 8-axis CNC spring machine uses 8 sets of servo motors and abandons the traditional 5-axis cam reducing mechanism. The CNC system directly controls spring diameter and reducing diameter, making it easy for new operators to learn and understand. For large diameter variation, the control system can automatically set the angle between two coiling pins and calculate the most reasonable vertex position of the coiling circle to ensure precise circle size. The auxiliary core cutter mechanism adopts hydraulic locking after lifting for easy operation with low vibration and high incision precision. Straight cut, subtend cut, swing cut, and twist cut functions are included. Wire feeding uses two-speed transmission for high speed and low speed. The 5G-3D (AW5000) touch screen control system includes a remote Internet interface and a 3D automatic programming template that generates spring programs automatically; it can be equipped with an image detector.
