Differences in Polishing Processes for Different Ferrule Diameters
Large Diameter Ferrule Face Grinding Process（FC/SC/ST-PC）
| Process | Rubber Pad | Polishing Film | Auxiliary Liquids | Time | Pressure |
| Degumming | PR5X-500-80 | GA5D 30um | Distilled water | 30s | Pressurization after 10 rpm |
| Rough grinding | PR5X-500-80 | DR5D 5um | Distilled water | 30s | Pressurization at start |
