Choosing a Spring End Grinder: Downfeed vs. Crash Grinding Explained

Spring end grinding is often the last step separating a coiled part from a finished component that sits flat and square in its assembly. Choosing the right grinding method — downfeed or crash — depends on your part geometry and production volume.

DOWNFEED GRINDING

The grinding wheel feeds down gradually onto the spring end, producing a controlled, precise finish well suited to tighter tolerance requirements and a wider range of spring sizes.

CRASH GRINDING

The spring end is ground in a single pass against the wheel, offering faster cycle times for high-volume production where the tolerance requirement is less demanding than downfeed grinding provides.

OUR END GRINDER LINEUP

WHY THIS MATTERS

The right grinding method affects both part quality and cycle time — get it wrong and you're either over-processing low-tolerance parts or under-delivering on tight-tolerance ones. Share your tolerance requirement and volume, and we'll match the right grinding approach to your part.
