A guard for a part to be shot-blasted and having an axis of revolution, the guard including: a cover and a chamber shaped for receiving the part to be shot-blasted; the chamber having at least one planar section with a shape matching at least one planar section of the cover; two side guards mounted on the part to be shot-blasted and having one degree of freedom relative to the chamber and the cover, wherein the cover, the chamber and the two side guards form a box for sealing the shot, the box including a window for projecting the shot, the surface of which matches a portion of a surface of the chamber.

A method of altering an additively manufactured part can include orienting a surface of the additively manufactured part toward a rotational center that may be independent of a rotational axis defined by the additively manufactured part, flowing an abrasive media past the surface, rotating the additively manufacturing part about the rotational center; urging abrasive particles in the abrasive media past the surface abrasive media to impinge the surface with centrifugal force generated by the rotating, and improving surface finish of the surface.

Handheld dust collector (or disposable dust cabinet) for sandblasting small objects, such as extraoral sandblasting of dental devices. The apparatus may comprise a bag with an open, resealable end. An access panel on the bag allows a user to insert their fingers into the bag, such as with integrated finger cots. A filter may be provided to allow air to escape from the bag. Methods of treatment are disclosed.

Disclosed herein are systems, methods, and apparatuses for managing abrasive media in cavitated fluid. One system includes a set of sensors in communication with the cavitated fluid in the 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. A method includes determining a density of abrasive media in the cavitated fluid in the processing tank and 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 density of abrasive media. One apparatus includes modules for performing the method.

The present invention relates to a mobile blasting apparatus for injecting abrasives onto the surface of an article to be processed, the mobile blasting apparatus comprising: a body; a frame structure including a first rail extending along a first direction; a first moving device which can move the position of the body reciprocally along the first rail; and an injection device coupled to the body so as to inject the abrasives. According to the present invention, all processes can be automated without workers' manual work, so that the overall working time is reduced even when an article to be processed is large in length or volume, and there is no concern that work over a long time, strong jets of abrasives, and noxious dust would cause harm to worker health.

Fluid jet systems, components and related methods are provided which are well adapted for processing workpieces under particularly work-friendly conditions. Embodiments include fluid jet systems and related methods that reduce, minimize or eliminate a gap between a workpiece being processed and jet receiving devices that receive and dissipate the energy of a fluid jet passing through the workpiece. Other embodiments include fluid jet systems and related methods involving fluid jet processing of workpieces in a submerged condition. Still further embodiments include fluid jet systems and related methods involving position and orientation adjustment of a fluid jet receptacle to coordinate the path of an incoming fluid jet with a central axis or other feature of the fluid jet receptacle.
