Abstract: To provide a surface property inspection apparatus, surface property inspection system, and surface property inspection method capable of inspecting the surface processing state of processed material subjected to surface processing such as shot-peening, heat treatment, or nitriding with high accuracy and low vulnerability to temperature changes in the inspection environment. Surface property inspection apparatus is furnished with a AC power supply, a AC bridge circuit, and an evaluation device; AC bridge circuit comprises variable resistor with which distribution ratio γ is variable, reference detector, and inspection detector. Inspection detector is furnished with a coil wound so as to oppose the surface property inspection region of object under inspection M, and by supplying AC power from AC power supply to coil, an eddy current is excited in object under inspection M. Thus the magnetic properties of object under inspection M can be detected, and inspection of surface properties based on the output signal from AC power supply is possible.

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: The present invention provides a surface property inspection method and apparatus for inspecting the surface properties of a test object subjected to two stages of shot peening. The present invention is an apparatus 1 includes an AC power supply, an AC bridge circuit, and an evaluation apparatus. The AC bridge circuit is constituted by a variable resistor, a reference detector and inspection detector. The inspection detector includes a coil wound so as to oppose the surface property inspection area of the test object M; an eddy current is excited in the test object M by supplying AC power to the coil. A pass/fail judgment of the first shot peening can be made by inspecting the surface properties of a test object subjected to a second shot peening only after the second shot peening is completed.
