In a comparative experiment on ultrasonic vibration grinding and traditional grinding, the impact of varying grinding parameters on grinding force and surface roughness was tested. Also, the mechanism of removing plastic and brittle properties of hard-brittle materials was analyzed based on the testing results. The study demonstrates that the grinding efficiency for hard-brittle materials can be improved using ultrasonic vibration grinding method although the roughness is slightly high. It is a practical technology for processing hard-brittle materials. Key words: hard and brittle materials; silicon wafer; ultrasonic vibration grinding; roughness 0 引 言 主轴 近些年，硬脆材料（如工程陶瓷、硅片等）的
