The first decision in sizing a CNC spring coiler isn't the brand or the control system — it's the wire diameter range you need to run. Get that wrong and every other spec becomes irrelevant. Here's how our two coiler families split that range.
CNC COMPRESSION SPRING COILER — FINE TO MEDIUM GAUGE
- Model range. CNC-508, CNC-516, CNC-528 (3-roller), CNC-208, CNC-223, and CS-250 cover fine to medium wire gauges.
- Ultra-fine capability. Down to 0.1mm wire diameter — suited to miniature springs for electronics, medical devices, and precision instruments.
- Best fit. High-precision, smaller-diameter production where consistency and fine control matter more than raw tonnage.
CNC LARGE COMPRESSION SPRING COILER — SHA SERIES
- Model range. SHA-630 through the SHA-5160~8300 and SHA-6250~8300 configurations, covering wire diameters from 1.2mm up to 30.0mm.
- Best fit. Heavy-duty industrial springs, automotive suspension components, and other applications where wire gauge and load capacity scale up significantly.
HOW TO DECIDE
- Know your full range, not just your current part. If your production roadmap includes both fine and heavy-gauge work, it's worth discussing a facility that runs both machine families rather than committing to one.
- Factor in volume and floor space. Large coilers have a bigger footprint and are sized for higher-tonnage output — share your production volume target alongside your wire range.
WHY THIS MATTERS
Matching wire diameter range to machine platform up front avoids the costly scenario of a machine that technically runs your part but never hits your tolerance or cycle-time target. Share your wire gauge range and we'll recommend the right platform.
