Description

Technical Field

[0001] The utility model belongs to the field of grinding, in particular to a ceramic sheet edge grinding device. Background Art

[0002] The preparation process of ceramic sheets usually includes the following steps:

[0003] Material preparation: Select appropriate ceramic materials, such as alumina (Al2O3), zirconium oxide (ZrO2), silicon nitride (Si3N4), etc., and grind and mix them as needed to obtain a uniform material.

[0004] Pressing molding: Put the prepared ceramic material into the mold and apply a certain pressure to form the material into the desired shape and size in the mold. Commonly used molding methods include dry pressing molding, injection molding, compression molding, etc.

[0005] Sintering: The formed ceramic sheet is placed in a high temperature environment for sintering. During the sintering process, the ceramic material will undergo chemical reactions and grain growth at high temperatures, making it dense and strong. The sintering temperature and time are regulated according to the characteristics and requirements of the material.

[0006] Surface treatment: The sintered ceramic sheets may need surface treatment, such as grinding, polishing, coating, etc., to improve surface quality and performance.

[0007] Inspection and Packaging: The quality of the ceramic sheets is inspected to ensure that they meet the standards and requirements. The ceramic sheets are then packaged for transportation and storage.

[0008] Among them, in the process of grinding, a grinder is needed for grinding. For small-sized items such as ceramic sheets, a handheld grinder is usually used for grinding. In this process, an object needs to be used to press the ceramic sheet. Only when the ceramic sheet is fixed can it be polished. Pressing can be done by hand, or by using an object to press down. These are inconvenient for operating the grinding process. Utility Model Content
