Further, described matrix is steel alloy.
Further, the granularity of the diamond abrasive is 100~270 mesh.
Further, a kind of diamond resin vitrified abrasive preparation method, it is characterised in that：Including following operative step：
Step one：Granulated after the resinoid bond, the diamond abrasive, the vitrified bond are well mixed, then uniformly it is fitted into mould, it is compressing under a predetermined, then the green compact high temperature sintering that will be molded, so as to obtain the abrading block of diamond resin vitrified abrasive；
Step 2：Matrix is Nian Jie with the abrading block that the step one is obtained so as to prepare diamond resin vitrified abrasive.
Further, the predetermined pressure is 20MPa.
Further, the sintering temperature is 750~820 DEG C.
Diamond resin vitrified abrasive prepared by use vitrified bond of the invention and resinoid bond has high in machining efficiency, integrated cost is low, novel environment friendly, it is nontoxic, the characteristics of being easy to use and promote, can effectively lift the processing efficiency of Buddha's warrior attendant glass, reduce processing cost, the pollution to environment is reduced, high hardness material attrition process use requirement is met.In addition, bonding agent firing temperature of the invention is strong 750~820 DEG C of holds to abrasive material, diamond used is greatly reduced under the process system of design damages, and process of lapping medium plain emery wheel is without finishing.
With reference to specific embodiment, the present invention is further detailed explanation.
