Grinding wheel for polishing and grinding ceramic tile biscuit, manufacturing method of grinding wheel and polishing and grinding apparatus and polishing and grinding method for ceramic tile biscuit

Abstract

The invention relates to a grinding wheel for polishing ceramic tile blanks, a manufacturing method, a polishing device and a polishing method, and belongs to the technical field of ceramic tile processing. Wherein, the grinding wheel includes a mandrel, an elastic layer and a grinding layer. In the radial direction of the grinding wheel, the elastic layer is fixed between the mandrel and the grinding layer. The grinding layer consists of grinding blocks. By arranging an elastic layer between the grinding block and the mandrel, the missing throwing rate can be effectively reduced.

Description

Technical field [0001] The invention relates to an abrasive tool and a manufacturing method and use method thereof, in particular to a grinding wheel for polishing a ceramic tile blank and a manufacturing method thereof, a polishing device constructed with the grinding wheel, and a polishing device for ceramic tiles. The method of polishing and grinding the blank. Background technique [0002] In the process of ceramic tile production, a layer of glaze is laid on the ceramic tile blank by glazing or spraying. In order to improve the flatness of the tile surface and reduce the use of glaze, before the glaze or spraying process, It is necessary to use a grinding wheel to polish the surface of the ceramic tile. [0003] Such as figure 1 Shown is a kind of grinding wheel 01 commonly used for polishing ceramic tiles. It is composed of a mandrel 011 and a cylindrical grinding layer 012. The grinding layer 012 is sleeved outside the mandrel 011 and fixedly connected to it. During the pr...

Problems solved by technology

[0003] like figure 1 Shown is a grinding wheel 01 commonly used for polishing ceramic tile blanks, which is composed of a mandrel 011 and a cylindrical grinding layer 012. The grinding layer 012 is sleeved outside the mandrel 011 and fixedly connected with it. During the process, the grinding surface 0120 of the grinding layer 012 is in hard contact with the surface of the tile green, and the amount of grinding is large, so it can be quickly polished; In the case of high and low around or high in the middle of the bottom at both ends, there will be 30% missed throws

[0004] In order to reduce the missed throwing rate, abrasive belts are usually used instead of grinding wheels to polish the surface of the tile green body. Although the missed throwing rate is reduced, the polishing life of the abrasive belt is as short as one day, and the abrasive belt needs to be replaced frequently, which is not conducive to reducing Production cost of tiles

[0005] In addition, since the polishing and grinding of the tile green is dry grinding, it is mainly cooled by wind, but the air cooling effect is not very ideal, and it is easy to cause the grinding heat effect on the surface of the grinding wheel and the surface of the tile green
