研磨抛光是机械加工领域中精密光整加工的重要手段。在传统研磨抛光中,特别是对硬脆性材料进行研磨抛光时,存在高硬度、低断裂韧性和化学性质稳定等特点,对其进行研磨抛光时很难获得理想的加工效率和优越的表面质量等问题。压电超声辅助研磨抛光属于振动研磨技术的一种,它将超声振动磨削技术应用于研磨加工,其高频振动能有效减小研磨力,提高加工效率,可充分发挥硬研磨工艺特点。该文结合压电超声辅助研磨抛光特性和研究方法现状,对国内外超声辅助研磨抛光硬脆材料的发展动态进行了综述与展望。

Grinding and polishing is an important means of precision finishing in the field of machining.In traditional grinding and polishing,especially when grinding and polishing hard and brittle materials,there are characteristics such as high hardness,low fracture toughness and stable chemical properties.It is difficult to obtain ideal processing efficiency and superior surface quality when grinding and polishing.The piezoelectric ultrasonic assisted grinding and polishing is a kind of vibration grinding technology,which applies ultrasonic vibration grinding technology to the machining process.Its high frequency vibration can reduce the grinding force,improve the processing efficiency,and can give full play to the characteristics of hard grinding process effectively.According to the research status of the characteristics and mechanism of ultrasonic assisted grinding and polishing,the development trends of the ultrasonic assisted grinding and polishing of the hardness and brittle materials at home and abroad are reviewed and prospected.
