Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. 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. 2. The grinding cavity body of multiple vibration sources of claim 1 , wherein the cavity body is polygonal with at least four sides, or cylindrical. 3. The grinding cavity body of multiple vibration sources of claim 1 , wherein the vibration frequencies of the weak ultrasonic vibration sources are 10 KHz-30 KHz, and the vibration frequencies of the strong ultrasonic vibration sources are 35 KHz-50 KHz. 4. The grinding cavity body of multiple vibration sources of claim 1 , wherein the plurality of ultrasonic vibration sources are arranged as a rectangle on the bottom of the cavity body. 5. The grinding cavity body of multiple vibration sources of claim 1 , wherein the plurality of ultrasonic vibration sources are arranged as a circle on the bottom of the cavity body. 6. 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 inside 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 converge toward a center of the cavity body. 7. The grinding cavity body of multiple vibration sources of claim 6 , wherein the cavity body is polygonal with at least four sides, or cylindrical. 8. The grinding cavity body of multiple vibration sources of claim 6 , wherein the vibration frequencies of the weak ultrasonic vibration sources are 10 KHz-30 KHz, and the vibration frequencies of the strong ultrasonic vibration sources are 35 KHz-50 KHz. 9. The grinding cavity body of multiple vibration sources of claim 6 , wherein the plurality of ultrasonic vibration sources are arranged as a rectangle on the bottom of the cavity body. 10. The grinding cavity body of multiple vibration sources of claim 6 , wherein the plurality of ultrasonic vibration sources are arranged as a circle on the bottom of the cavity body.
