摘要： The present invention discloses a multi-dimensional vibration grinding cavity body (11, 21). By adjusting amplitudes (power) and frequencies of the multi-dimensional ultrasonic vibration source (12, 22, 14, 24), such that the multi-directional macroscopic flow is formed in the cavity body (11, 21) while keeping the vibration medium to have the original characteristics to improve the performance of grinding of slurry.

摘要： The present invention discloses a grinding cavity body (11, 21, 31, 41) of multiple vibration sources, in which a plurality of ultrasonic vibration sources (121, 221, 321, 421, 122, 222, 322, 422) are disposed, capable of controlling the multi-directional macroscopic medium flow, making benefits to the vibration medium (the abrasive of the slurry) to enter the fine structure of the workpiece to be processed, and to the abrasive to vibrate itself slightly to enhance the performance of abrasive to the workpiece which needs to be ground.
