💡 Why does a precision index pin lose its mark when vibrating machines run constantly?
The fix is pretty handy once you realize you gotta balance the spring preload with your clamping torque instead of cranking the nut down.
- Match the threaded locating sleeve thickness to your base plate to prevent rotational slip under heavy torque loads.
- Clear out accumulated cutting fluid and metal chips from the bearing cavity so the detent ball seats cleanly every time.
- Swap out weakened compression springs before they cause positional wandering on your production floor.
