Abstract: A system for magnetorheological finishing of a substrate. A spherical wheel meant for carrying a magnetorheological finishing fluid houses a variable-field permanent magnet system having north and south iron pole pieces separated by primary and secondary gaps with a cylindrical cavity bored through the center. A cylindrical permanent magnet magnetized normal to the cylinder axis is rotatably disposed in the cavity. An actuator allows rotation of the permanent magnet to any angle, which rotation changes the distribution of flux in the magnetic circuit through the pole pieces. Thus, one can control field intensity in the gaps by positioning the permanent magnet at whatever angle provides the required field strength. Because the field also passes above the pole pieces, defining a fringing field outside the wheel surface, the variable field extends through a layer of MR fluid on the wheel, thus varying the stiffness of the MR fluid as may be desired for finishing control.

Abstract: A polishing device is disclosed. The polishing device includes a load seat and two polishing mechanisms mounted on the load seat. Each polishing mechanism includes a driving member and a polishing member driven by the driving member. The two polishing members of the two polishing mechanisms are oppositely received in the receiving space, and oppositely rotatable driven by the corresponding driving member. The polishing members are rotated oppositely, such that the new burs generated by one of the polishing members can be removed by other one of the polishing members at the same time.

Abstract: Disclosed is a deburring apparatus. The deburring apparatus includes a transfer module installed on a base to form a transfer path of transferring a workpiece to be deburred, a deburring module provided on the transfer path of the workpiece installed on the base to deburr the workpiece, and a blocking cover installed on the base to reciprocate thereon to selectively prevent the transfer module and the workpiece on the transfer module from being exposed to an outside, and to prevent dust and noise, which are produced when a deburring work is performed for the workpiece by using the deburring module, from being delivered to the outside. The burrs, which are produced when a metallic produce or a non-metallic produce having a 3-D shape is molded or cut, are easily and rapidly removed.

Abstract: A prescription label identity peeler includes a box-shaped housing. A lid extends over the box-shaped housing. A sanding member is adjustably carried within the box-shaped housing. A pair of linkage arms is pivotally extend between the lid and the sanding member. The motorized linkage arms will move the sanding member simultaneously and horizontally against the empty pill bottle in an inverted position, while the wheel on the swing arm assembly will contact a bottom end of the empty pill bottle via compression of the springs, thereby removing the label from the empty pill bottle when the inverted empty pill bottle rotates.

Abstract: The invention is directed toward a chemical mechanical polishing/planarizing (CMP) brush with an embedded mandrel. PVA foam injected into the substantially hollow mandrel expands through apertures in the mandrel to fill a mold in the desired shape of the brush with the foam in the mandrel being integral with the outer foam covering the brush.

Abstract: In the peripheral length correction device of metal rings, a metal ring is laid on a driving roller and a driven roller which are displaceable in mutually separating directions. One or both of the rollers are displaced while rotating the rollers, thereby applying tensile stress to the metal ring to correct the peripheral length thereof. The peripheral length correction device of metal rings further comprises a foreign substance removal head, which functions as the removal means for removing foreign substances adhered to the inner peripheral surface of the metal ring, and as the re-adhesion prevention means for preventing re-adhesion of the foreign substances removed by the removal means from the metal ring.

Abstract: Apparatus is provided for superpolishing the inside diameter surface of a seam of a flexible continuous photoreceptor belt.

Abstract: There are disclosed a polishing method and a polishing device in which cleaning of a glass substrate surface can be achieved to a high level. A glass substrate (MD substrate 1) in the shape of a circular disc having a circular hole in a center portion is immersed in an abrasive liquid 50 containing free abrasive grains, and an inner peripheral end surface of the glass substrate is polished using the abrasive liquid containing the free abrasive grains by rotating a rotary brush 4 or a polishing pad in contact with the inner peripheral end surface.

Abstract: A system comprising a rotary buffing device for removing the mold-flash from leadless leadframe substrate panels is described. The leadless leadframe substrate panels have bottom surfaces that contain electrical contact landing and die attach pad surfaces. Covering at least some of the surfaces of the electrical contact landings and the die attach pads are formations of mold-flash, which are thin layers of molding material. The rotary buffing device is rotated at a sufficiently high rate such that the formations of flash are brushed (or buffed) off the bottom surfaces as the rotary wheel is run along the substrate panels.

Abstract: Device for mechanically cleaning wire rod for profiled metal wires, comprising at least one press (3) with gripping jaws (4a, 4b) rotating about the wire rod (2) and supporting an abrasive material (5), such as steel wool for example, arranged in one or more layers around the wire rod (2), pressed against it by the jaws (4a, 4b) and retained by the latter so as to prevent it being drawn along; operating members (6a, 6b) consisting of floating plates (8) joined together in an ordered manner in pairs so that each pair interacts autonomously with the abrasive material (5); means (7) for actuating the operating members (6a, 6b), able to modify the opening of the jaws (4a, 4b); means (10) for synchronizing the relative sliding movement of the plates (8) of each pair in the transverse direction with respect to the rod (2) and able to cause identical displacements of the said plates (8) in opposite directions.

Abstract: There is provided at least one of a moving device for moving a graining brush in the width direction of aluminum web and a turning device for turning the graining brush so that the graining brush can be placed obliquely against a transporting direction of the aluminum web. By moving the graining brush periodically in the width direction of the aluminum web, the entire graining brush uniformly comes into contact with the aluminum web. By turning the graining brush to place it obliquely against the transporting direction of the aluminum web, the entire graining brush can always come into contact with the aluminum web. Accordingly, the abrasion in the bristles of the graining brush is maintained uniform.

Abstract: An abrasive cleaning apparatus has an integral drum formed of inner and outer layers of resilient material and a rigid layer in between. Holes are formed through the drum in a spiral pattern around the drum. A wire is engaged in each hole, the wire having opposing ends and three bends. One end of the wire is inside the drum with an adjacent portion lying circumferentially on an inner surface of the drum. A portion of the wire outside the drum is aligned in an opposite circumferential direction as the portion of the wire inside the drum. A retaining cylinder sandwiches the end inside the drum between itself and an inside surface of the drum, holding the wire stable. The end of the wire inside the drum is in close proximity to ends of adjacent wires, which inhibits rotation of a wire in its hole in the drum.

Abstract: A process for surface treating the surface of petrous materials comprises applying friction to the surface to be treated by means of brush bristles which produce progressive erosion of the surface wherein the erosion is of greater depth in zones of lesser hardness. The process removes parts of lesser consistency from the surface. The process is performed without chemical treatment, sand blasting or the application of fire to texture and may be performed in the presence of water.
