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 cutting method by applying a particle beam of metallic glass onto a substrate to cut or partially cut the substrate with high production efficiency, low production cost and better environmental protection.

An impeller for a centrifugal blast wheel machine includes a hub provided at one end of the impeller, with the hub being configured to be coupled to the motor. The impeller further includes a tapered section provided at an opposite end of the hub, with the tapered section defining a media inlet to receive blast media. The impeller further includes a plurality of drop-shaped vanes positioned between the hub and the tapered section. The plurality of drop-shaped vanes is spaced from one another on peripheries of the hub and the tapered section. The plurality of drop-shaped vanes defines a plurality of impeller media outlets constructed and arranged to allow egress of blast media upon rotation of the impeller. Each vane is drop-shaped having a leading side directed toward a direction of rotation of the impeller and a trailing side opposite the leading side.

A centrifugal blast wheel machine comprises a housing and a wheel assembly coupled to the housing. The wheel assembly has a plurality of blades configured to throw blast media introduced into the wheel assembly against a work piece. According to one embodiment, each blade of the plurality of blades includes a curved portion positioned adjacent a central hub of the wheel assembly, and a straight portion integrally formed with the curved portion extending radially outwardly from the wheel assembly. According to another embodiment, each blade includes a first side rail extending along the blade, the first side rail having a first recess, and a first grommet positioned in the first recess.

An impeller for a centrifugal blasting wheel includes a base plate, a support collar, and a plurality of spaced rotor blades interconnecting the base plate and support collar. A step is formed at the inner end of the collar and the outer ends of the rotor blades which causes blasting shot to be discharged to the throwing blades of the blasting wheel in a relatively more radial direction to reduce wear of the throwing blades. The base plate also has a frustum-shaped central boss formed to minimize wear of the base plate by the blasting shot. The frustum-shaped central boss has a recess formed therein so that the head of the bolt that connects the impeller to the throwing wheel is located entirely within the recess to also reduce wear of the bolt head.

A vane for insertion into a slot of a wheel of a blasting assembly such that the vane propels media as the wheel is rotated includes a body radially extending between a first vane end and a second vane end, between a first flange and a second flange, and having opposing vane side surfaces. An attachment portion integral with the second flange, the attachment portion configured to be received into the slot, and the attachment portion having a first vane end retaining surface and a second vane end retaining surface that are configured to abut the wheel. The first vane end retaining surface and the second vane end retaining surface are adjacent to each other, the first vane end retaining surface is convex, and the second vane end retaining surface is concave.

A shot blasting wheel for use with a shot blasting machine configured to propel abrasive shot against a workpiece. The shot blasting wheel includes a circular body member defining a plurality of slot openings a front surface defines a plurality of slots. Each slot and slot opening has a dovetail configuration. The shot blasting wheel includes a plurality of blade assemblies, each including a paddle positioned in a respective slot via insertion through a respective slot opening. Each blade assembly also includes a locking lever pivotally coupled to the body member and pivotally movable between a locked configuration preventing removal of the paddle from the respective slot and a released configuration allowing removal.
