Description

technical field [0001] The invention relates to an abrasive tool and a manufacturing method thereof, in particular to a vitrified metal bonded abrasive tool and a manufacturing method thereof. Background technique [0002] Abrasive tools include grinding layers. For some small abrasive tools, the whole is usually a grinding layer, such as small cup-shaped grinding wheels; Grinding the mandrel with the required pressure and power, the grinding layer is usually made from the raw material through pressing and / or sintering steps. [0003] In the process of polishing the workpiece with abrasive tools, a large amount of heat will be generated. In order to dissipate the heat in time, it is usually cooled with grinding fluid; however, grinding fluid is not used in some polishing processes. For example, in the process of polishing tile biscuits, only dry grinding can be carried out, mainly by air cooling, but the cooling effect is not ideal. [0004] In order to solve the above pro...

Problems solved by technology

[0003] In the process of polishing the workpiece with abrasive tools, a large amount of heat will be generated. In order to dissipate the heat in time, it is usually cooled with grinding fluid; however, grinding fluid is not used in some polishing processes. For example, in the process of polishing ceramic tiles, only dry grinding can be carried out, mainly by air cooling, but the cooling effect is not ideal

[0004] In order to solve the above problems, the thermal conductivity and lubricating properties of the grinding tool are improved by adding graphite as an additive; however, there are the following problems in using graphite as an additive: (1) During the sintering process of the grinding tool, due to the As high as 600-800 degrees Celsius, and the sintering atmosphere is air atmosphere, graphite will be partially oxidized and invalidated; (2) During the dry grinding process, due to local high temperature and air atmosphere, graphite will be partially oxidized and invalidated

These problems are usually solved by increasing the amount of graphite used, and using the increased amount of graphite to fill the part that has failed due to oxidation, but this will reduce the grinding performance such as the life and sharpness of the abrasive tool
