A Method to Solve the Fragmentation of Grinding Ultrathin Zirconia Ceramics

Ultra thin zirconia ceramic sheets are prone to fragmentation and edge collapse during grinding. Due to their crystalline nature, being too thin can result in the workpiece being unable to withstand the grinding force brought by the grinding equipment. Crystal breakage during friction extrusion and other processes is very easy. The technical difficulties in grinding zirconia ceramics are all caused by the characteristics of zirconia itself. It can be seen that the characteristics and parameters of each workpiece affect the configuration of grinding equipment, consumables, machine structure, and process procedures.

It is necessary to use zirconia ceramic fixation method to test the perfect value of the pressure system and fixation system, so as to achieve the optimal fit between the workpiece and the grinding disc, so that the zirconia ceramic will not withstand excessive grinding force and cause the workpiece to break during grinding.

In addition, the grinding of zirconia ceramics requires professional surface grinding machine technology, and different zirconia ceramic materials require the selection of different grinding consumables and accessories for operation. These are also some conclusions drawn by zirconia ceramic grinding machine processing engineers from practical applications.
