Pyramid Grinding Disc

Abstract

The invention relates to the technical field of grinding equipment, in particular to a pyramid grinding disc, which comprises a cylindrical base body, at least one bottom surface of the base body is connected with a grinding layer, and the grinding layer comprises a grinding bottom layer, a plurality of grinding edges, the grinding bottom layer and the grinding The blade is integrally formed, and the grinding bottom layer is located between the base body and the grinding blade. The grinding blade is an annular protrusion centered on the center of the base body. The grinding blade is connected to the grinding bottom layer through the root. After the end of the grinding blade is worn, the exposed part forms a new end, and the workpiece can be ground, so that the end of the grinding blade can maintain a certain roughness, and the grinding can be continued. Therefore, the pyramid grinding disc of the present invention can be The cutting rate is ground and maintained for a long time, and the operator applies almost the same pressure conditions during the whole grinding process, which can carry out smooth and continuous processing, which is convenient for processing, and it is easy to obtain a good and consistent fine grinding effect.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a pyramidal grinding disc capable of finely grinding crystal materials such as gemstones, silicon wafers and wafers. Background technique [0002] In the industry, it is often necessary to treat the surface of the workpiece to achieve a certain level of flatness, especially for crystal materials such as sapphire, silicon wafers, wafers, and substrates, which have higher requirements for surface treatment. Therefore, it is necessary to grind the surface of the workpiece with a grinding disc and a grinding liquid. [0003] From a microscopic point of view, the surface of general solid materials has a certain degree of roughness and porosity. For grinding discs, the surface has tiny, sharp protrusions. When the grinding disc moves relatively on the workpiece, these sharp protrusions The surface of the workpiece can be ground. In the prior art, the granular material is u...

AI Technical Summary

Problems solved by technology

In the prior art, the granular material is usually molded to form a disc-shaped grinding disc, and its working surface is a plane, which can increase the working area of ​​grinding, but after working for a period of time, the workpiece and the grinding disc will be worn The debris fills the surface of the grinding disc, reducing its surface roughness, causing the cutting rate of the grinding disc to drop rapidly, forcing the operator to exert more pressure, which will increase the labor intensity of the operator and increase the risk of overcutting
