Description
Technical Field

Background
In the fields of electronic information and precision engineering, high-hardness brittle materials such as semiconductor materials, ceramic materials and the like play an important role. For successful application in the above-mentioned fields, such materials generally need to be processed very precisely to ensure extremely high precision and extremely low surface roughness. However, the characteristics of the high-hardness brittle material make the material difficult to process, and abrasive particle processing, particularly fine abrasive particle processing, is a mainstream mode of processing the material. The abrasive grain processing comprises free abrasive grain processing and fixed abrasive grain processing, and the free abrasive grain processing can naturally obtain lower surface roughness, but for high-hardness brittle materials, the free abrasive grain processing efficiency is lower, and the shape accuracy of a workpiece is difficult to ensure; the fixed abrasive particles are only suitable for processing coarser abrasive grains due to the limitation of the agglomeration effect of fine abrasive grains, and the workpiece is difficult to obtain smaller surface roughness.
Therefore, in the method, the fine-grained abrasive particles are easier to uniformly disperse in liquid, the fine-grained abrasive particles are uniformly dispersed in a certain solution, and then the gel is generated through chemical reaction to realize retention and holding of the abrasive particles. The gel binder polishing tool can well meet the processing requirements of hard and brittle materials, and has extremely wide application prospects.
However, the gel grinding tool is mainly prepared manually at present, the efficiency is low, the quality is difficult to ensure, and the development of the semi-solid abrasive processing technology is limited. Therefore, the realization of automated mass production of gel abrasive tools is of great importance for the development and application of semi-solid abrasive machining.
