SFI-740
Invention patent technology with 7-axis CNC control for compact, precise spring production.
Compact, high-precision CNC coiling
- 7-axis CNC system with 7 servo motors replaces cam mechanisms.
- CNC controls outside diameter and spring diameter without mechanical slider changes.
- Servo-driven auxiliary core cutter for precise, convenient adjustments.
- Supports straight, opposite, swing, and twisting cutting functions.
- 5G-3D (AW5000) touch control with remote interface and auto-programming.
Machine Features
Details extracted from the provided SFI-740 image.
The 7-axis CNC spring machine uses 7 servo motors, abandoning the traditional cam mechanical coiling axis slider. The CNC system directly controls the outside diameter and spring diameter, so the spring rotation only needs the control system to adjust without changing the mechanical reducer slider. The auxiliary core cutter is servo controlled with the cutter, allowing both to move together and maintain the optimal position when changing spring diameter. Straight cutting, opposite cutting, swing cutting, and twisting cutting functions are included. The 5G-3D (AW5000) touch screen control system includes a remote Internet interface and a 3D auto-programming template that generates spring programs automatically; it can be equipped with an image detector.
