Abstract

The invention discloses a preparation method of an abrasive tool. In this method, the matrix is ​​first placed in the mold, and then the grinding head material is added, so that the grinding head material surrounds a section of the matrix, and isostatically pressed to obtain a green mold body; the green mold body is baked and dried, and the The drying temperature is 90-120°C, and the baking time is 5-8h; after the green mold body is baked and dried, it is sintered at a high temperature. room temperature, made. The abrasive tool prepared by the method of the present invention is prepared by using a combination of diamond micropowder, metal powder and wollastonite as abrasives, fluorite, feldspar and garnet as auxiliary additives, bonded by an adhesive, and strengthened by tire powder. The abrasive tool has high bending strength and hardness, and a large wear resistance coefficient, which is suitable for grinding hard metal alloy materials.

Description

technical field [0001] The invention belongs to the technical field of grinding material preparation, and in particular relates to a preparation method of an abrasive tool. Background technique [0002] Abrasives are tools used for grinding, grinding and polishing. Most of the grinding tools are artificial grinding tools made of abrasives and bonding agents, and natural grinding tools are also directly processed into natural ore rocks. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasive tools are also used in the processing of non-metallic materials such as grain processing, paper industry, ceramics, glass, stone, plastic, rubber, and wood. [0003] The structure of abrasive tools is roughly divided into three categories: tight, medium and loose. Abrasives with a loose structure are not easy to be passivated during use, and generate less heat during the grinding process, which can reduce heat deformation and burns of ...
