CNC Spring Forming Machine | Cam-Driven Wire Coiling
Watch a cam-driven CNC wire forming machine coil and shape spring wire at multiple stations - precise compression springs made automatically.
Key Specifications
- Materials
- Spring steel wire
Key Features
- Forms coils and legs automatically at high speed
- Multiple cam stations work in sync on every part
- Precise wire feed controls spring pitch and length
- Robust hardened tooling for long production runs
How Are Compression Springs Formed Automatically at Speed?
Short answer: On a cam-driven CNC wire forming machine. This video shows spring wire fed through a central collet into multiple synchronized cam stations that coil, shape and cut small compression springs continuously - precise geometry at production speed.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Feed | Powered wire feed and guide | Accurate wire advance per cycle |
| Grip | Central collet chuck | Wire held at the forming point |
| Form | Synchronized cam stations | Coil pitch and legs shaped together |
| Cut | Knife at the head | Finished spring released, cycle repeats |
Key Applications
- Compression, extension and torsion spring production
- Automotive, appliance and furniture spring components
- Hardware factories moving off manual coiling
- High-volume custom wire form production
Cam-Driven Forming vs. Single-Axis CNC Bending
| Criterion | Single-axis bender | Cam-driven forming machine |
|---|---|---|
| Coil winding | Limited | Dedicated coiling cams |
| Stations per cycle | Sequential | Many cams in sync |
| Output speed | Moderate | Very high continuous rate |
| Best for | Frames, hooks | Springs and coiled parts |
FAQ
Can this machine make custom spring geometries? Yes - cam timing, wire feed and tooling are set per spring design, so coils, hooks and legs follow your drawing.
What wire range does the spring machine handle? The demonstrated unit runs small-diameter spring steel wire; the machine series covers sizes up to heavy coil spring wire.
How is spring length consistency maintained? The servo wire feed meters exact advance each cycle while the collet grips at the same point, keeping pitch and free length stable.
