Abstract

The invention discloses a ceramic resin composite bonding agent grinding wheel and a preparation method thereof, comprising the steps as follows: step I, a resin bonding agent, a grinding material, filler, and a pore forming agent are subjected to compression molding, and sintering is conducted at the high temperature of 700 to 850 DEG C so as to form a ceramic grinding wheel; step II, the resin bonding agent is dissolved by acetone or alcohol, a curing agent is added therein so as to blend resin bonding agent liquid; step III, the resin bonding agent liquid prepared in step II is put into a rubber mold, simultaneously, the ceramic grinding wheel is put into the rubber mold, the opening of the rubber mold is sealed, and the sealed mold is put into a cold isostatic press for pressing; step IV, the resin bonding agent grinding wheel subjected to processing of step III is put into an oven for roasting. The ceramic resin composite bonding agent grinding wheel not only keeps the original characteristics of a resin bonding agent diamond grinding wheel that the grinding efficiency is high, and the self-sharpening property is good, but simultaneously has the advantages of a metal bonding agent diamond grinding wheel that the rigidity is high, the heat resistance is high, and the molded surface is kept well.

Description

technical field [0001] The invention relates to a preparation method of an abrasive tool, which belongs to the field of preparation of porous abrasive tools, in particular to a ceramic resin composite bond grinding wheel and a preparation method thereof. Background technique [0002] At present, there are mainly three types of diamond and cubic boron nitride grinding wheels according to the type of bond: resin bond, metal bond, and vitrified bond. The three bond system grinding wheels have their own advantages and disadvantages during processing, and cannot completely meet the requirements. For example, the vitrified bonded diamond grinding wheel can easily control the porosity during the preparation process, and enough pores are used to store the grinding fluid and improve the self-sharpening of the grinding wheel. Compared with the resin bonded abrasive tool, its shape retention is better, and the processing size High precision; Compared with metal bond abrasives, it has t...
