In order to obtain a more precise quality zirconia ceramic is also used in micro-machining, so as to improve processing efficiency, cost reduction purposes. In the fine structure of the entire process, the most critical issue is to control the dimensional accuracy, what factors will affect by it?
Under normal circumstances, can be judged by comparing the microstructure of zirconia ceramic processing quality has a rule is obtained zirconia ceramic green strength greater the zirconia ceramic, the better the quality of the processing. Since zirconia ceramic raw embryo will be a certain volume shrinkage after sintering, the green body under pressure to suppress shrinkage will also change, so as to obtain the correct size of the fine structure, the dimensional accuracy of the factors in the size of the key control .
Micro machining, the tool is essential, and it will also appear worn, according to the volume loss rate and introduced a calculation tool axis loss amount of empirical formula. Finally, since the system axis deformation, tool wear, something to compensate for shrinkage results show that processing and baking size and target size is basically the same.
