Abstract
The cavitation process is performed on the inner surface of the target hole. The cavitation processing method includes; attaching a cap having a through hole to an inlet of a target hole of a workpiece; immersing the workpiece and a nozzle into a processing liquid; and ejecting a jet of the processing liquid from the nozzle located outside of the target hole to an inside of the target hole through the through hole such that a cavitation process is performed on a processing region that is located downstream of a non-processing region covered by the cap on an inner surface of the target hole.
Claims20
A cavitation processing method, comprising:
- attaching a cap having a through hole to an inlet of a target hole of a workpiece;
- immersing the workpiece and a nozzle into a processing liquid;
- and
- ejecting a jet of the processing liquid from the nozzle located outside of the target hole to an inside of the target hole through the through hole such that a cavitation process is performed on a processing region that is located downstream of a non-processing region covered by the cap on an inner surface of the target hole.
A cavitation processing apparatus configured to perform a cavitation process on a workpiece having a target hole having an inlet, the cavitation processing apparatus comprising:
- a cap attached to the inlet, the cap including,
- a head portion having a male thread portion, and
- a through hole configured to penetrate the head portion and the cover portion;
- a nozzle located outside the target hole, the nozzle configured to eject a jet of processing liquid through the through hole to an inside of the target hole;
- and
- a tank configured to store the processing liquid for immersing the workpiece with the cap and the nozzle.
