Zirconium oxide ceramics is one of the special ceramics. The purpose of processing zirconia ceramics is to process the zirconia ceramics to meet the requirements required for the purpose. So what are the processing difficulties of zirconia industrial ceramics? First, let’s understand the processing methods of zirconia ceramics.
Zirconium oxide industrial ceramic processing method
Among the processing methods of zirconia industrial ceramics, mechanical processing methods are more efficient, so they are also widely used in industry. Most other processing of zirconia industrial ceramics are more suitable for drilling, cutting or micro-machining.
Main difficulties in processing zirconia industrial ceramics
Although there are many methods for processing zirconia industrial ceramics, the processing cost is high, the processing efficiency is low, and the processing accuracy is also relatively poor.
One of the main reasons is that the hardness of zirconia industrial ceramics is very high. For green or calcined industrial ceramics, cutting is mainly used for rough processing, and grinding is used for finishing after sintering. Depending on the different conditions of the zirconia industrial ceramics, the sintered body can be directly ground and processed without processing to achieve the design accuracy. In the process of processing zirconia industrial ceramics, the machining allowance is large, which is prone to insufficient strength or surface processing defects, or the required final processing shape cannot be obtained due to insufficient clamping and other reasons.
Another problem with the processing of zirconia industrial ceramics is that the cost of processing tools is relatively high, and high-priced sintered diamond and CBN tools need to be used during cutting. Finishing is also mainly done with diamond grinding wheels, so the cost of the tools is higher than that of metal cutting. The cost of the tools used is dozens to hundreds of times.
The strength of zirconia industrial ceramics is very sensitive to processing, which is difficult to achieve and has low processing efficiency. Therefore, the processing cost of zirconia industrial ceramics is much higher than that of ordinary materials.
