Problems solved by technology

[0005] However, during the grinding process of bonded abrasives, the abrasive is prone to passivation due to the high pressure and impact force it bears, making it difficult to perform effective grinding for a long time. It not only wastes production time and labor costs, but also causes unstable and degraded product quality.

Abstract

The invention provides a diamond grinding material grinding tool. The diamond grinding material grinding tool is made of the following raw materials including diamond, auxiliary grinding materials, sodium chloride, filling materials and binding agents. The invention provides an addition agent which can enhance diamond exposure in the usage process of the diamond grinding material grinding tool. Sodium chloride is added to the formula of the diamond grinding material grinding tool, and therefore the exposure of diamond in the grinding process can be enhanced, the phenomenon of passivation of diamond in the grinding process is effectively avoided, and the grinding force of the diamond grinding tool is improved. A method is easy and convenient to operate and low in cost, and can effectively reduce the surface roughness of a processed product and improve the surface quality of the processed product.

Description

technical field [0001] The invention belongs to the technical field of superhard material tool manufacturing and optical device processing, and relates to a diamond abrasive abrasive, in particular to a diamond bonded abrasive abrasive. Background technique [0002] Consolidated abrasives are abrasives (grinding materials). The abrasives are fixed on the surface of the grinding tool by auxiliary materials such as binders, and the tools with a certain shape and certain grinding ability are made, including grinding wheels, grinding discs, grinding Abrasive belts, grinders, grinders, abrasive belts and ultra-fine polishers, etc. [0003] The use of fixed abrasive grinding is called fixed abrasive grinding. Fixed abrasive grinding is improved and innovated to address the shortcomings of discrete abrasive grinding. It is made of special abrasives for grinding by solidifying the abrasive paste. Compared with discrete grinding, the grinding efficiency and grinding quality have bee...
