Development of Vitrified Diamond Grinding Wheel for Engineering Ceramics

Abstract

Newly developed engineering ceramics are very difficult to be ground using conventional diamond grinding wheel because of their poor dressability and low cutting ability. In this study, a rigid and porous vitrified diamond grinding wheel was made so that a diamond grain might not deteriorate and it might be tightly bonded to the bond bridge using proper frit bond at lower firing temperature. According to the grinding test results, the grinding force was very low and dimensional accuracy of ground ceramics was very excellent.
