Abstract

The invention relates to a preparation method of a ceramic bond diamond grinding wheel, and belongs to the technical field of ceramic materials. The ceramic bond prepared by the invention can realize the low-temperature sintering of the diamond grinding wheel; the ceramic bond has thermal expansion performance with the diamond abrasive, can avoid or reduce the thermal stress generated between the diamond abrasive grains and the ceramic bond when the grinding wheel is working, and improve the bond The ability to bond and hold the diamond abrasive particles; the ceramic bond has high toughness, and the appropriate toughness can ensure the cutting effect of the diamond abrasive micro-edge, improve the impact resistance of the grinding wheel during grinding, and ensure the shape stability of the grinding wheel; ceramics The bonding agent has good wetting and coating properties for the diamond abrasive, which is beneficial to improve the bonding strength between the two and the overall strength of the grinding wheel; the addition of lanthanum oxide rare earth metal oxide or other subgroup metal oxides in the present invention can effectively optimize the glass network structure, improve the strength and hardness of the ceramic bond, and enhance the grinding performance of diamond abrasive tools.

Description

technical field [0001] The invention relates to a method for preparing a vitrified bond diamond grinding wheel, which belongs to the technical field of ceramic materials. Background technique [0002] Diamond is the substance with the highest hardness known so far. In order to exert the grinding performance of diamond, it is usually necessary to prepare it into an abrasive tool with certain specifications, properties and uses with the help of binders and other auxiliary materials. [0003] Vitrified bonded diamond abrasive tools have important application value and broad application prospects in the field of mechanical processing due to their good heat resistance, water resistance, oil resistance, acid and alkali resistance, good shape retention and high grinding efficiency. However, in the process of abrasive tool preparation, on the one hand, due to the relatively low oxidation resistance temperature of synthetic diamond abrasives, the sintering of vitrified bond abrasive ...
