Manual and mechanical coiling built the spring industry — but as tolerances tighten and product mixes grow more complex, the limits of operator-dependent production become the constraint. Here's what changes when coiling moves to CNC control.
WHERE MANUAL/MECHANICAL COILING FALLS SHORT
- Operator-dependent variation. Manual adjustment introduces part-to-part variability that's hard to eliminate, even with skilled operators.
- Slower changeover. Switching between spring specifications on mechanical equipment often requires manual re-tooling and re-calibration.
- Limited geometry. Complex or asymmetric spring geometries are difficult or impossible to hold consistently without programmable multi-axis control.
WHAT CNC CONTROL ADDS
- Programmable repeatability. Once a program is set, every part coils to the same specification — run after run, shift after shift.
- Faster changeover. Stored programs let operators switch between spring specifications in a fraction of the time mechanical re-tooling requires.
- Complex geometry capability. Multi-axis CNC control enables variable-pitch, conical, and other advanced spring geometries that mechanical coilers can't reliably produce.
WHY THIS MATTERS
Consistency is what separates a part that passes incoming inspection from one that gets rejected — and CNC coiling is what makes that consistency achievable at volume, across a growing range of spring geometries.
