Abstract: The purpose of the present invention is to provide a shot peening apparatus for which size increase is limited by projecting a shot material evenly on a workpiece using a single projector. The present invention provides a shot peening apparatus equipped with a workpiece-conveying mechanism for conveying a workpiece and a projector for projecting a shot material at the workpiece. The workpiece-conveying mechanism is equipped with: a pair of rollers, which extend in the workpiece conveyance direction, on which the workpieces are loaded, and which are rotated centered on the longitudinal axis line; an endless chain; and conveyance members for pressing and conveying workpieces in the conveyance direction. The projector is a centrifugal projector and is equipped with: a control cage into which the shot material is supplied and in which a first opening and a second opening are formed; and a bladed wheel, which is provided with multiple blades having a backward-sloping section that slopes toward the back in the rotation direction and which rotates centered on the central axis line of the control cage. The first opening and the second opening of the control cage are separated from each other in the circumferential direction of the control cage and are disposed offset from each other in the direction of the central axis line of the control cage.

Abstract: A first inspection step nondestructively inspects a surface side state of a treatment target to be subjected to shot processing of shooting shot media at the treatment target and evaluates that the treatment target is failed when an inspection result deviates from a first allowable range predetermined. A condition setting step sets a shot processing condition in response to the inspection result of the first inspection step for the treatment target evaluated as not failed in the first inspection step. A shot processing step performs shot processing of shooting shot media at the treatment target evaluated as not failed in the first inspection step in the shot processing condition set in the condition setting step. A second inspection step after the shot processing step nondestructively inspects a surface side state of the treatment target.
