A shot processing apparatus including: a cabinet with a processing chamber formed therein, the processing chamber allowing a workpiece to be conveyed thereinto; a ejecting mechanism ejecting a shot media to a hole of the workpiece; and a conveyance device conveying the workpiece between a preparation position for the workpiece and the cabinet, wherein the conveyance device includes a plate-like rotary table provided to be rotatable about a rotation axis, being provided with a conveyor for moving the workpiece on an upper surface of the rotary table, and allowing the plurality of workpieces to be arranged thereon, the rotary table connects the conveyor to the preparation position and the cabinet at a predetermined rotational position, and the shot processing apparatus has an inspection area for inspecting a state of the hole of the workpiece, between the preparation position and the rotation axis of the rotary table.

Disclosed herein are components, systems, and methods for performing a finishing operation on an article. Finishing operations include, but are not limited to removal of powder from a surface, improving surface finish, and peening. Embodiments of the disclosed components, systems, and methods include the use of waterjets to impact a surface of the article with an abrasive. Impacting the surface of the article with the abrasive alters a characteristic of the article without cutting through the portion of the article.

A cavitation nozzle is disclosed, including a plate, a hollow body, and a cap removably engaged with the hollow body and holding the plate against a distal end of the hollow body. The plate may have a central aperture and a distal surface, wherein the distal surface is bisected by a groove and the hollow body is configured to deliver high pressure fluid through the central aperture. The delivered high pressure fluid may be discharged as a cavitating jet.
