Abstract
The present invention discloses a grinding cavity body of multiple vibration sources, in which a plurality of ultrasonic vibration sources 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.
Claims10
A grinding cavity body of multiple vibration sources, comprising:
- a cavity body, configured to contain an abrasive slurry;
- and
- a plurality of ultrasonic vibration sources, disposed on a bottom of the cavity body, wherein the plurality of ultrasonic vibration sources are classified as strong ultrasonic vibration sources and weak ultrasonic vibration sources according to vibration frequencies, and the weak ultrasonic vibration sources are disposed outside the strong ultrasonic vibration sources;
- wherein the plurality of strong ultrasonic vibration sources and weak ultrasonic vibration sources respectively generate ultrasonic vibrations in two different frequencies to make the abrasive slurry flow upward from the bottom of the cavity body and spread out from the center of the cavity body.
