Abstract

To make a grinding wheel for nano-precision grinding, it is necessary to achieve fine-grained and uniformly dispersed abrasive grains in the bonding material. Such well-classified uniformly dispersed diamond abrasives and bonding resin particles were obtained using the method proposed in the previous report. An ultrasonic press machine was then developed to fabricate denser grinding wheels, and the grinding performances of two types of wheel were evaluated in this study. Compared to the conventional wheels, the grinding ratio was increased by threefold and the surface roughness was decreased by 60% using the developed wheels.
