Controlling Apex and Angle on conical ferrules is much more difficult than with step ferrules, namely because we need to control the “depth of cut” – the amount of ferrule material we remove during the polishing process. This means we must ensure the polishing films we use have exceptional lot-to-lot abrasive consistency. Also, since the abrasive cut-rate of polishing films declines the more times we use the film, we will likely need to reduce the number of times we reuse the films in our process (this will increase polishing costs). Because the step ferrule is unaffected by depth of cut, abrasive cut-rate variation has much less effect on our results.

With both conical and step ferules, the Radius we generate has a similar effect on measured Apex and Angle. In general, targeting a Radius at the lower end of our tolerance limits will improve our chances of acceptable Apex Offset and Angle measurements.
