径向超声振动磨削与纵向超声振动磨削 ,其主要差别是磨粒与工件的接触状态不同 ,在径向超声振动磨削中 ,磨粒与工件的接触是间断性的 ,它的临界速度特征符合现有的振动切削理论 ,而在纵向超声振动磨削中 ,磨粒与工件是永久性接触 ,不存在磨粒与工件表面分离的特点。根据它们的差别作者建立了磨粒纵向超声振动切削模型 ,得到了纵向超声振动珩磨临界速度的新概念及其计算公式。
Radial ultrasonic vibration grinding and longitudinal ultrasonic vibration grinding, the main difference is that the contact state of the abrasive particles and the workpiece is different. In the radial ultrasonic vibration grinding, the contact between the abrasive particles and the workpiece is discontinuous, and its critical speed The characteristics are consistent with the existing theory of vibration cutting, while in the longitudinal ultrasonic vibration grinding, the abrasive particles are in permanent contact with the workpiece, and there is no characteristic that the abrasive particles are separated from the workpiece surface. According to their differences, the authors established the abrasive longitudinal ultrasonic vibration cutting model, and obtained the new concept and calculation formula of the critical speed of longitudinal ultrasonic vibration honing.
