Contamination within the ferrule bore is wearing the bore, creating larger bore diameter: Ferrule bore wear is unavoidable over time—as thousands of ceramic ferrules are inserted and removed from a stainless steel fixture, the bore will wear. However, contamination of the bore, particularly with abrasive particles naturally resulting from the polishing process (the “slurry” referred to above), can accelerate this wear.
As the bore diameter becomes larger, the ferrule is held to less than 90-degrees to the polishing surface, resulting in larger Apex Offset and Angle values.
