Ceramic surface polishing is a more precise processing method in ceramic processing. Alumina ceramics can also obtain a greater smoothness (Ra0.1) after grinding or polishing, as follows Mingrui Ceramics Factory will introduce to you its precision polishing process.
In order to improve the accuracy of the product, most alumina ceramic materials need further finishing treatment after completing the sintering process to achieve a higher surface finish.
Because the hardness of alumina ceramic materials is relatively good, harder grinding and polishing tile materials need to be used for finishing, such as SIC, B4C or diamond, etc.; and in precision During the processing, the lubricity of the surface of the alumina ceramic material must be improved in advance.
In terms of finishing of alumina ceramic materials, the more common method is to grind step by step from coarse to fine abrasives, and then polish the surface. When polishing, you can choose to use less than 1μm Micron Al203 powder or diamond paste is used for grinding and polishing. Of course, laser processing and ultrasonic processing can also achieve the purpose of grinding and polishing alumina ceramics.
The above is a finishing process to improve the surface finish of alumina ceramic materials, and then to enhance the mechanical strength of alumina ceramics, which is alumina ceramic strengthening technology . In fact, advanced processes such as electron beam vacuum coating, sputtering vacuum coating or chemical vapor evaporation are used on the surface of alumina ceramics to temper the alumina ceramics.
