Ceramic processing is a workshop dedicated to processing ceramics. Ceramic processing requires special processing tools and processing techniques. The processing of ceramic materials is a special case of mechanical processing, and the general machining workshop does not have the capability of ceramic processing.
Characteristics of ceramic processing
1. Ceramics have requirements Outer Diameter Polished Silicon Nitride Ceramic Rods Bars for size and surface accuracy, but due to the large sintering shrinkage rate, the accuracy of the size of the sintered porcelain body cannot be guaranteed, so it needs to be processed after sintering;
2. Ceramic materials have the characteristics of high hardness, high strength and high brittleness, which are difficult to process materials.
Ceramic processing method
For ceramic materials, due to their special physical and mechanical properties, they can only be processed by grinding methods at first. With the development of machining technology, a variety of processes similar to metal processing can be used to process ceramic materials.
1. Abrasive processing: grinding processing, polishing processing, abrasive belt processing, drum processing, ultrasonic processing, Outer Diameter Polished Silicon Nitride Ceramic Rods Bars shot peening processing, viscoelastic flow processing;
2. Plastic processing: diamond plastic processing, diamond plastic grinding;
3. Chemical processing: etching, chemical grinding, chemical polishing;
4. Electrical processing: EDM, electron beam processing, ion beam processing, plasma processing;
5. Compound processing: photolithography processing, ELID grinding, ultrasonic grinding, ultrasonic grinding, ultrasonic electric discharge machining;
6. Optical processing: laser processing.
