Why do zirconia ceramics have dimensional tolerances after finishing?

Zirconia ceramic products have precision errors or tolerance ranges after ceramic machining, so what is the reason for its appearance? Pintejin Ceramics Factory will give you an analysis.

​Zirconium oxide ceramic grinding is a kind of machining method to eliminate chips on the surface of the workpiece. Therefore, the dimensional change in the process of zirconia ceramic machining should be continuous. In the process of zirconia ceramic grinding, it can always reach a high level. accuracy. The grinding and polishing of zirconia ceramics is often the last process in the machining of a workpiece, and it is also a process that determines the accuracy of the workpiece. There is a certain relationship between the grinding accuracy of zirconia ceramics and the surface roughness of the workpiece.

Zirconia ceramic gasket In addition to the influence of the grinding disc of the zirconia ceramic grinding equipment on the workpiece, external factors will also have a certain impact on the workpiece. These effects are the reasons for the changes in the workpiece during the grinding process, which are roughly as follows. The elastic deformation between the equipment and the workpiece caused by the grinding of zirconia ceramics; and the vibration factor generated in the grinding process. To improve the grinding accuracy of zirconia ceramics, the rigidity of the workpiece is determined by the requirements irrelevant to grinding. Different from general grinding, the elastic deformation produced has a great relationship with the machining.

In the grinding of zirconia ceramics, the correct feed depth cannot process the ideal workpiece precision size. Repeated grinding of zirconia ceramic workpieces is extremely important. In the case of zirconia ceramics grinding, the zirconia ceramic workpieces are The amount of feed has a lot to do with the workpiece during continuous feeding. The difference between the workpiece after zirconia ceramic machining is that it will change with the number of times the zirconia ceramic is ground. The shape error of the roughest workpiece of zirconia ceramics cannot be eliminated in one-time grinding of zirconia ceramics.
