How to reduce the fragmentation of ultra-thin zirconia ceramics in the grinding process

Zirconia ceramic is a new type of high-tech ceramics, which not only has the conditions of high strength, hardness, high-temperature resistance, acid and alkali corrosion resistance, and high chemical stability but also has higher toughness than ordinary ceramics. zirconia is also used in various industries, such as shaft seal bearings, cutting components, molds, auto parts, etc., and even can be used in the human body, such as artificial joints.

Zirconia can be divided into ultra-thin zirconia ceramic pieces according to their thickness. Because it is ultra-thin, a big problem encountered in production is that it is easy to break when grinding. Why does this happen? And how to solve it? Let’s find out.

The ultra-thin zirconia ceramic sheet is easy to break (especially the edge) during grinding, mainly because it belongs to crystal material, and the workpiece is too thin to bear the grinding force brought by the grinding equipment, and it is easy to break the crystal in the process of friction and extrusion.

All the difficulties in the grinding technology of zirconia ceramics are brought about by the characteristics of zirconia itself. Thus it can be seen that the characteristics and parameters of each kind of workpiece will indirectly put forward requirements for the configuration of grinding equipment, consumables, machine structure, and technology.

The solution is to adjust the equipment and technical process for a period, test the pressure system, and fix the perfect value of the system so that the workpiece and the grinding disc reach the best-fit state so that the zirconia ceramic grinding will not bear too much grinding force and cause the workpiece to be broken.

In addition, the grinding of zirconia ceramics needs professional surface grinder technology, and different zirconia ceramic materials need to choose different grinding materials and accessories for operation. These are also some conclusions drawn by the processing engineers of zirconia ceramic grinding machines from the practical application.
