在超声波复合振动机理的基础上，分别对纵向振动和两种横向振动组成的Ⅰ型、Ⅱ型超声波复合振动的加工特性进行了较系统的试验研究．研究结果表明：Ⅰ型超声波复合振动可以对未烧结陶瓷等非导电限性材料的异型孔穴、窄槽进行高效加工，而Ⅱ型超声波复合振动适用于对上述材料进行精细加工． Based on the mechanism of ultrasonic compound vibration, the processing characteristics of the type I and type II ultrasonic composite vibrations consisting of longitudinal vibration and two kinds of transverse vibration are systematically studied. The results show that the type Ⅰ ultrasonic vibration can be used to process irregular shaped cavities and narrow grooves of nonconductive materials such as unsintered ceramics, while the type Ⅱ ultrasonic vibration is suitable for the fine processing of the above materials.
