Systems for managing abrasive media in cavitated fluid include a set of sensors in communication with cavitated fluid in a processing tank and a processor coupled to the set of sensors. The processor is configured to determine a density of an abrasive media in the cavitated fluid in the processing tank and facilitate maintaining the density of abrasive media in the cavitated fluid in the processing tank at a level that is greater than or equal to a threshold level of abrasive media. The processor is further configured to command the abrasive media addition device to add the recycled abrasive media to the processing tank to increase the density of abrasive media in the cavitated fluid in response to determining that an average density of abrasive media is less than the threshold density of abrasive media.

To provide a cavitation processing device that provides proper cavitation effect for an appropriate processing position. The cavitation processing apparatus includes a nozzle configured to eject cavitation fluid; a direction changing member configured to change a flow direction of the cavitation fluid, the direction changing member having groove for guiding the flow direction of the cavitation fluid, the groove configured to suppress cavitation bubbles contained in the cavitation fluid from dispersing; and a workpiece fixing member on which a workpiece is arranged.

Provided is a cavitation processing apparatus for providing cavitation effects such as residual stress evenly on the surface and inner part of the component. The cavitation processing appratus includes: a nozzle that ejects cavitation fluid to a workpiece; a direction changing member that changes a flow direction of the cavitation fluid that collided with the workpiece to be branched toward inside; a driving apparatus including a rotary shaft, the driving apparatus that rotates the workpiece together with the rotary shaft; and a support member supporting one end of the rotary shaft.

A shot processing apparatus is equipped with a work set jig, a hanger transport device, a projection machine, a projection positioning unit and a clamp unit. The work set jig is equipped with a base member including an upper and lower pair of cross members and a vertical member. A workpiece is settable at the base member between the upper and lower pair of cross members. The hanger transport device is, with the work set jig in a hanging state, movable along a guide path in the shot processing apparatus and is capable of stopping thereon. The projection machine projects projection media at a workpiece set at the base member inside a projection chamber which the workpiece is conveyed into. The projection positioning unit positions the work set jig at a stopping position in the projection chamber. The clamp unit fixes a workpiece between the upper and lower pair of cross members.

A workpiece drive for rotating a circular workpiece in a descaling device has a carrier and at least three support roller modules. Each of the support roller modules has a bearing and a support roller for the circular workpiece. The support roller has a longitudinal axis, a lateral surface and a radius between the longitudinal axis and the lateral surface, and the radius decreases in a longitudinal direction along the longitudinal axis. The bearing supports the support roller rotatably around the longitudinal axis. Each of the support roller modules has a drive and the drive is designed to rotate the support roller around the longitudinal axis. The bearings are arranged on the carrier in such a way that the longitudinal axes have a point of intersection and lie in a plane perpendicular to the earth gravity field vector and such that the longitudinal directions are directed towards the point of intersection.

A depowdering apparatus for depowdering a cake comprising a build part includes a depowdering chamber, a blast nozzle, and a build elevator. The depowdering chamber includes a bottom surface and a build inlet extending through the bottom surface, where the build inlet includes an inlet axis that is substantially vertically oriented. The blast nozzle is positioned within the depowdering chamber and oriented to direct a fluid stream toward the inlet axis. The blast nozzle is laterally spaced from the inlet axis and operable to revolve about the inlet axis on a travel path encircling the inlet axis. The build elevator is arranged below the build inlet in a vertical direction and is operable to raise the cake comprising the build part through the build inlet and into the depowdering chamber along the inlet axis as the blast nozzle is revolved about the inlet axis on the travel path.
