An apparatus for blasting a media onto a surface comprises an oscillating nozzle, a mount and a power source. The mount attaches the nozzle to tooling, enabling the nozzle to be raised and lowered about a vertical axis, and enabling the nozzle to be repositioned about a horizontal axis. The power source enables the nozzle to oscillate. The blasting media is sprayed through the nozzle onto the surface. The oscillating nozzle projects an enlarged dispersion pattern of the blasting media onto the surface being treated. The apparatus may include a basket positioned near the mount, enabling an operator to be positioned upon a truss and control the blasting of the media onto the surface, the basket being mounted via a swivel bearing, enabling the basket to self-level. Also, the media blasting apparatus may be controlled by an operator positioned in a remote control computer area.

A workpiece cutting apparatus includes a cutting table with a workpiece receiving surface, at least two longitudinally-extending rails extending longitudinally on opposed sides of the cutting table and substantially parallel to one another, a bridge with an elongated cutting assembly support and engagement arms at opposed ends thereof, and at least two driving assemblies. Each one of the engagement arms includes a bridge engagement member engageable with a corresponding one of the at least two longitudinally-extending rails, from below. Each one of the driving assemblies operatively connects each one of the engagement arms to the corresponding one of the at least two longitudinally-extending rails. The at least two driving assemblies are actuable to translate the engagement arms along the at least two longitudinally-extending rails. A method of cutting a workpiece using the workpiece cutting apparatus and a method for assembling a workpiece cutting apparatus are also provided.

Disclosed herein is a system for surface treating an internal surface of a part. The system comprises a tank within which the part is locatable. The system also comprises a fluid within the tank and capable of submersing the part when the part is located within the tank. The system further comprises a nozzle submersed in the fluid and configured to generate a stream of cavitated fluid directed in a first direction. The system additionally comprises a deflection tool submersed in the fluid and comprising a deflection surface that redirects the stream of cavitated fluid from the first direction to a second direction. The first direction is away from the internal surface of the part and the second direction is toward the internal surface of the part.

A carving cabinet configured to enable carving of the work-piece outside the main machine cabinet, without requiring the work-piece to be completely wrapped in a protective covering. The carving cabinet includes a housing defining an enclosure for operating the carving tool when carving the work-piece. A barrier member is coupled to the housing and is configured to substantially separate the work-piece from the enclosure when carving the work-piece. The barrier member includes a first surface facing toward the enclosure and an opposing second surface facing away from the enclosure. A carving port extends between the first surface and the second surface. The barrier member is configured to allow the work-piece to be disposable adjacent the second surface to enable carving of the work-piece through the carving port.
