Zirconium oxide ceramicRing mirror polishing is one of the ceramic plane polishing processes , the main components of its material arezirconia. Pure zirconia is generally white, and appears yellow or gray when containing impurities. Due to its characteristics, many problems will arise during the processing of zirconia ceramic rings. How to solve them, Mingrui precision zirconia ceramics manufacturer will introduce them to you below.
1 The thickness of the ceramic ring is extremely small. During the processing process, it is easy to cause chipping and edge collapse due to the grinding force of the grinding equipment, thus affecting the finished product qualification rate.
2 Problems with the zirconia material itself. Because the structure of the zirconia ceramic material itself will change correspondingly under different temperature environments, we must do a good job of cooling during the grinding process to avoid material changes due to temperature, resulting in imperfect polishing results
Solution:
1. Before rough grinding, the materials should be initially screened, mainly to screen out problematic materials visible to the eye, such as materials with wrong colors and impurities. Avoid unnecessary losses due to material problems.
2. In view of the extremely thin characteristics of the ceramic ring itself, special tests were carried out and a new fixing method was used to test the critical point of the perfect combination between the pressurizing method and the fixing method, so as to To achieve the best fit between the workpiece and the grinding disc.
3. In view of the fact that the crystal state of zirconia is prone to change due to temperature, we specially set up a complete set of cooling devices for it.
4. During the grinding and polishing process, we adopt the process of rough polishing, semi-fine polishing, and fine polishing, using an appropriate amount of copper or iron plates, and using ceramic plates as polishing paper. Mirror polishing machine for processing.
