Provided is a centrifuge media separator for separating blast particulate from fine particulate carried by air flowing from a blast cabinet and through the media separator. The centrifuge media separator comprises an upper panel, a lower panel, and an outer wall. The upper panel has a central opening formed therein. The outer wall is configured in a truncated logarithmic shape and which extends between the upper and lower panels. The outer wall has at least one particulate escape aperture formed therein. The upper panel, lower panel and outer wall collectively define a curvilinear air passageway having an inlet and an outlet. An air foil extends from the outer wall in to the air passageway. The distance than the air foil extends in to the air passageway is adjustable. The inlet is configured to allow a flow of air to enter the air passageway and circulate therethrough toward the outlet. The escape aperture is configured to exhaust the blast particulate out of the passageway. The central opening is configured to exhaust the fine particulate out of the passageway.

A method for vibroblasting surfaces using a vibroblasting machine, said vibroblasting machine being equipped with at least one toroidal shaped process vat (50) which is set in a rotary motion and is suitable for containing workpieces whose surfaces are subjected to a vibroblasting processing, said method including a phase of inputting fine particles belonging to a sandblasting media into said process vat (50) to proceed with a sandblasting action of the surfaces of the workpieces being processed, and a phase of evacuation of said fine particles, characterized in that the phase of inputting fine particles belonging to the sandblasting media into said process vat (50) occurs from top to bottom or tangentially to the circumference of said process vat (50) and to the surface of the vibrating mass (75) of the workpieces and of the media.

A waterjet system in accordance with at least one embodiment of the present technology includes a cutting head and an associated catcher assembly. The cutting head directs an abrasive-containing waterjet toward a workpiece supported by a cutting deck of the catcher assembly. The catcher assembly also includes a tank and a container fluidly connected to the tank. The tank contains abrasive-containing liquid in which the waterjet diffuses after the waterjet passes through the workpiece. The container collects abrasive at least primarily by shielding abrasive-containing liquid within the container from at least some turbulence of abrasive-containing liquid within the tank during operation of the waterjet system. The catcher assembly also includes a quick-release coupling through which the container is removably connected to the cutting deck. Operating the quick-release coupling allows the container to be removed to dispose of the collected abrasive.

A blasting or stripping booth is provided creating a generally downward flow for treatment of fluid and particle flow, which reduces operator exposure to potentially hazardous debris. The booth comprises an enclosure defining an upper region for a workpiece, a lower region, and a separator assembly. In some instances the separator assembly includes individual separator units which are discrete units, each having a generally square or rectangular plan view configuration which are arranged in an array for providing the required process flow capabilities. Further embodiments utilize structures forming the separator which have an elongated trough-like configuration. These embodiments find a particular application in large-scale stripping or blasting booth used in production environments where workpieces may flow through a treatment system in a serial manner. Other suitable applications include batch type processing of parts.

A shot treatment device includes, a rotary table rotatable in a first rotation direction about a first rotation shaft extending along a vertical direction, a plurality of placement tables arranged at intervals in a circumferential direction on an upper surface of the rotary table, an ejector configured to eject shot media, a first inspection detector configured to inspect surface properties of a workpiece, a shot chamber in which shot media is ejected to a workpiece, and a first inspection chamber provided downstream in the first rotation direction from the shot chamber. The ejector ejects shot media to a workpiece held on a first placement table that has entered the shot chamber, and the first inspection detector capable of ascending and descending is disposed above a second placement table that has entered the first inspection chamber and inspects surface properties of a workpiece held on the second placement table.

Various examples of the disclosure relate to a blast machine having a process chamber. A tumble belt, for example, can be arranged in the process chamber. Techniques for venting the process chamber are described. Techniques for fastening the tumble belt are described. Techniques for operating blasting nozzles are described.

The invention relates to a method and an apparatus for producing three-dimensional models by layering technology, using a core cleaning station.

The subject of the invention is an abrasive blast machine for surfaces of large-scale workpieces comprising a housing (O) constituting a working chamber, a kinematic mechanism for moving the effector, an abrasive recirculation system, an effector feeding system with recirculated abrasive, characterized in that the kinematic mechanism is a multipart kinematic mechanism (MK) with at least four-axis, and in that, the effector is an impact turbine (T), which produces the treatment tool and directs it to the workpiece.

An apparatus capable of efficiently performing a metal surface processing. The abrasive peening apparatus includes a processing tank storing abrasive particles and peening liquid, and including a bottom portion in which a workpiece is immersed in the peening liquid; a dispensing chamber having a plurality of recesses on an upper surface, and disposed in the bottom portion to dispense the peening liquid; a stirring nozzle disposed at a center of the recess directing vertically upward and connected to the dispensing chamber to eject the peening liquid; a peening nozzle immersed inside the processing tank to eject the peening liquid toward the workpiece; and a moving device moving the peening nozzle relative to the workpiece.

The invention relates to implement the sealing, porosity and sweeping functions, combined. For this purpose, the present invention proposes to confine the waste and to suction the waste at the ejection head by means of a sufficiently flexible connection, such as to remain in contact with the machining area. According to an embodiment, a portable machining machine (1) operated by a pressurized jet (112) includes a waste recovery system (5), an injection head (11) which is provided with a nozzle (111) having an axis (A1) that is substantially perpendicular to the surface to be machined (4a) and which is driven by a digitally controlled two-axle guide system, the ejection head (11) being extended by an enclosure (12) to the surface area to be machined (4a). In addition, the enclosure (12) comprises a tubular portion (121) consisting of two walls (12a, 12b) which slide coaxially along the axis (A1) and a double-pivot articulation device (123). The enclosure (12) has a porous annular wall (124) in a plane substantially perpendicular to the axis (A1) of the nozzle (111), said annular wall (124) having sufficient resilience to keep the enclosure (12) in permanent sealing contact with the surface to be machined (4; 4a, 4b).
