Abstract

The invention discloses a glass-ceramic binding agent for a superhard grinding wheel, a preparation method of the glass-ceramic binding agent, the superhard grinding wheel, a manufacturing method of the superhard grinding wheel, and a composite grinding wheel. The glass-ceramic binding agent is composed of a basic ceramic bond and an additive. The basic ceramic bond is prepared from, by mass, 55%-65% of SiO2, 2%-10% of Al2O3, 5%-20% of B2O3, 0-5% of CaO, 0-5% of K2O, 5%-15% of Na2O, 0-5% of Li2O, 0-5% of BaO, and 0-8% of ZnO. The additive is one or more of ZnO, Y2O3, ZrO2, CaF2, Na3AlF6 and Na2SiF6. According to the glass-ceramic binding agent, the variety and adding amount of the additive can be regulated flexibly, simply and quickly.

Description

technical field [0001] The invention relates to the field of abrasives, in particular to a glass-ceramic bond for superhard material grinding wheels and a preparation method thereof, a superhard material grinding wheel and a preparation method thereof, and a composite grinding wheel. Background technique [0002] Superabrasives (diamond, cubic boron nitride) have the advantages of high hardness, good wear resistance, and good thermal stability, and have been widely used in grinding tools, such as superhard material abrasives. In the preparation process of superhard material abrasive tools, it is necessary to use a bonding agent to consolidate the superhard abrasive into a certain shape, so that the abrasive mill has a certain hardness and strength. However, during the grinding process, due to the insufficient strength of the superhard material abrasive tools, problems such as excessive abrasive shedding and grinding wheel breakage often occur. Not only the grinding effect is...
