In recent years, many scholars have applied the diamond grinding method to systematically study the theory and process of plastic grinding of brittle materials of zirconia ceramics, brittle-plastic transition, material properties, cutting force and other parameters. Plastic way surface formation mechanism and geometric accuracy of zirconium ceramic parts, including research and development of related machine tool and grinding wheel technology. 1. Machining of zirconia ceramics: The machining of zirconia ceramic materials is not only suitable for semi-sintered body ceramics, but also for fully sintered body zirconia ceramics. The cutting process of semi-sintered zirconia ceramics is to reduce the machining allowance of fully sintered body ceramics as much as possible, thereby Read more

Grinding usually refers to the use of micron-scale abrasive particles with a hardness that is farther away from the material to be processed, and the micro-cutting and rolling action generated by the hard grinding disc to achieve the removal of trace materials on the machined surface, so that the shape and size of the workpiece are accurate. Reach the required value, reduce the surface roughness, and reduce the machining method of machining the metamorphic layer. 1. Grinding Mechanism Advanced ceramic materials are hard and brittle materials that are difficult to machine. In the grinding process of such materials, the material to be processed is removed by the rolling action or Read more

Zirconia ceramics and materials containing zirconia ceramics are widely used. Due to the excellent physical and chemical properties of zirconia, it has a prominent position in engineering ceramics and advanced ceramics, such as industrial ceramic rods, ceramic plungers, and ceramic shafts. Wait. Due to its high melting point and chemical inertness, pure zirconia can be used as a refractory material, however, the transformation from tetragonal to monoclinic during thermal cycling can cause severe bulk cracking of the material. Many applications of zirconia therefore require it to be alloyed with alkaline earth oxides or rare earth oxides to give it a fully or partially stable structure. At present, the alloying elements Read more
