Zirconium oxide ceramic is a new material in the machinery manufacturing industry. The hardness of zirconia ceramics is relatively high and stable. They have many superior characteristics such as strong sex, so they are loved by people. However, the processing of drilling holes in zirconia ceramics is very difficult, and a little carelessness may cause surface damage. Product types: ceramic plungers, ceramic pumps Core, ceramic valve core, ceramic piston, ceramic bushing, ceramic sucker, microporous ceramic, etc.; Materials: alumina, zirconia, silicon nitride, carbide silicon. The following is the method of drilling holes in zirconia ceramics introduced by the editor.
Zirconia ceramic drilling processing method:
Among the zirconia ceramic drilling processing methods, the efficiency of mechanical processing is generally relatively high, so it is widely used in industry, especially in diamond grinding wheel grinding, grinding and polishing. Most other processing methods of zirconia ceramics are suitable for drilling, cutting or micro-machining. When cutting, most of the time it is enough to use a diamond grinding wheel for grinding and cutting. When drilling holes, follow the instructions.Different hole diameters are processed by ultrasonic processing and grinding and grinding respectively.
Main problems in drilling and processing of zirconia ceramics:
Depending on the drilling process of zirconia ceramics, the sintered body can also be directly ground and processed to achieve the design accuracy. In terms of processing process, zirconia ceramics are almost the same as metal parts, but the machining allowance of zirconia ceramics is very large. When rough machining of unfired or calcined ceramics, it is easy to have insufficient strength or surface processing defects, or the final processing shape you require cannot be obtained due to insufficient clamping and other reasons. Since the shrinkage cannot be kept uniform during sintering, the roughDuring processing, the size must not be too close to the final size, so the margin left for finishing is very large.
Based on the above introduction, we should already know that there are many ways to drill holes in zirconia ceramics, but the processing costs are too high, and the precision of drilling holes in zirconia ceramics is relatively poor. , the main reason is that the hardness of zirconia ceramics is too high, so there are many methods for drilling holes in zirconia ceramics.
