QUESTION: We have an 8º MT polishing fixture and are getting polished angled less than 7.9º. Is there a problem with the polishing plate?
ANSWER:
Assuming you are using high quality polishing equipment, it is most likely NOT an issue with the fixture. The angle of the MT chip can be greatly affected by the Silicon Carbide grinding steps, and even more so when polishing a non-pre-angled ferrule. If, as in this case, the angles are too low, we’d recommend decreasing the polishing time during these early grinding steps. If the angled is too great, the time should be decreased. As long as the standard deviation for the angle is reasonable, you can move that average one way or the other by adjusting the process. If your standard deviation is large, meaning the results aren’t consistent, you likely have other issues.
