Problems solved by technology

[0005] The Chinese patent with publication number CN201210274354 discloses a fiber-reinforced matrix and its preparation method. Although it can well strengthen the grinding wheel matrix and realize simultaneous grinding, the main raw material selected is phenolic resin, which has low heat resistance. The grinding wheel made of it is difficult to withstand the high grinding heat generated during high-speed grinding, and the matrix preparation process is relatively complicated

Abstract

The invention discloses a grinding wheel used for grinding an outer circle and an end face synchronously. The grinding wheel comprises a base body and an abrasive material layer. The base body is prepared from, by weight, 10-20 parts of imide resin powder, 60-85 parts of metal powder, 2-10 parts of resin glue, 1-5 parts of metal glue, and 2.5-5.5 parts of a silane coupling agent. The abrasive material layer is a resin grinding wheel ring or a ceramic grinding wheel ring or a grinding wheel block. According to the grinding wheel, the resin glue and the metal glue are mixed to be used for pouring the base body, so that a resin phase and a metal phase are effectively bonded together, and thus the bonding performance and other performance are improved; and the rigidity, tenacity, heat conductivity and high-temperature performance of the base body are improved, synchronous wastage between the base body and the abrasive material layer can be achieved in the grinding process of the grinding wheel, and thus the performance of the grinding wheel and the surface quality of a machined workpiece are not affected.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing and processing, and in particular relates to a grinding wheel for synchronous grinding of outer circle and end face and a preparation method thereof. Background technique [0002] When grinding a ring-shaped or rod-shaped workpiece with a step, the outer circle of the workpiece and the end face of the step need to be processed to a certain size and surface quality. The currently used outer cylindrical grinding wheel includes SiC grinding wheel, superhard grinding wheel and composite material matrix. Superhard grinding wheels can realize the grinding of such workpieces, but there are certain defects and deficiencies. [0003] SiC grinding wheel grinding and processing such workpieces can realize synchronous grinding of the outer circle and the end face, but the efficiency is low, the grinding wheel is frequently dressed, and the service life is low. [0004] Since the superhard gr...
