A shot-processing device is provided, and by it they are effectively reused and prevented from being taken out of a cabinet and from scattering. A structure (40) for a flow path that connects the inside of the cabinet (12) and a suction port (70A) of a dust collector (70) includes a part of a route for circulation of a circulating machine (32) and a second flow path (40Y) that connects a chamber for blowing air and the suction port (70A). In the structure for the flow path a classifying part (35) is provided. It includes a first cyclone (36) that classifies particulate objects that include shots as shots that have a diameter that makes them reusable and as the other particulate objects and includes a part of the first flow path (40X), and a second cyclone (44) that includes a part of the second flow path.

A shot-peen forming system includes a shot-sourcing chamber and a plurality of conduits, each having a first end and a second end. The first ends are coupled to the shot-sourcing chamber for receiving a portion of shot. A plurality of peen-forming jets are coupled to the second end of a respective one of the plurality of conduits. The plurality of jets are each adapted to fire shot in one of a plurality of predetermined directions to simultaneously deliver shot to a workpiece. An omnidirectional shot peening delivery system includes a plurality of nozzles positioned for shot peening from a plurality of angles, respectively. A shot distributor is adapted to receive shot through an inlet and distribute shot to the plurality of nozzles, and a workpiece holder is adapted to constrain a workpiece for receiving shot from the plurality of nozzles simultaneously to provide conformity during shot-peen forming.

A powder chamber, in particular for powder polishing devices, including a casing and two functional sectors, whereby the two functional sectors are arranged to be opposite to each other, and whereby at least one functional sector is designed to provide an opening for a working medium such as air or a mixture of powder and air, and whereby the two functional sectors are designed to allow the powder chamber to be locked. The two functional sectors are preferably arranged along an axis and are rotationally symmetric.

Reduced noise abrasive blasting assemblies and systems are described. The new assemblies and systems are comprised of standard blast hose, accelerator hose, couplings and nozzle. The improved abrasive blasting system maintains abrasive particle velocity while decreasing the exit gas velocity and consequently decreasing sound production. This is accomplished through an acceleration section with reduced inner diameter and sufficient length to provide the necessary abrasive particle velocity. The new system maintains the productivity and efficiency of conventional abrasive blasting systems but with greatly reduced acoustic noise production and reduces operator fatigue due to the lower weight of the carried portion of the system.

A water jets cutting machine includes a first rotating seat driven by a first motor to rotate about a first rotation axis, a second rotating seat driven by a second motor to rotate about a second axis, a water jets cutting head, an inertial measurement unit (IMU) for detecting an inclination angle of the water jets cutting head, and a controller connecting the first and second motors and the IMU. The controller is able to control the first and second motors to instantaneously conduct compensation for angular deviation of the water jets cutting head according to attitude and position signals which are fed back to the controller by the IMU.

A wet blast machine for cleaning or preparing surfaces comprises: a treatment source for providing a pressurised mixture of treatment material; a nozzle, the nozzle comprising: an inlet for receiving the pressurised mixture of treatment material; an outlet for ejecting the pressurised mixture; and at least one hole in a wall of the nozzle, the hole for feeding one or more products into the nozzle such that one or more surfaces of the product are exposed to the treatment material whilst within the nozzle, allowing for a more efficient wet blast of the products.

A deadman switch system includes a primary deadman switch actuator and a secondary deadman switch actuator for controlling the flow of an air/abrasive mix through a flow line of a delivery system. The secondary deadman switch is positioned in series with a primary deadman switch actuator such that the controlled flow will not function unless first the primary deadman switch and then the secondary switch are closed. The preferred embodiment of the switch is a low-profile configuration adapted to be mounted in axial alignment with the flow line in a manner to minimize interference with normal operation of the system. The switch can include multiple open/close elements, for selectively controlling different flow functions.
