A magnetic polishing machine includes a container which accommodates a polishing target and a plurality of polishing pieces, a plurality of rotation plates which are rotatably disposed below the container while a magnet is attached to the rotation plate, and a first rotation mechanism which rotates each rotation plate about a rotation axis of the rotation plate. The adjacent rotation plates are disposed at a position in which rotation areas thereof partially overlap each other.

A system for magnetic abrasive finishing of a workpiece may include a magnetic abrasive brush that may include a plurality of magnetic/abrasive particles and an electromagnet configured to apply a magnetic field on the plurality of magnetic abrasive particles. The system may further include a first actuating mechanism that may be configured to actuate a rotational movement of the workpiece about a longitudinal axis of the workpiece, a second actuating mechanism that may be configured to actuate a linear movement of the magnetic abrasive brush along a first direction relative to the workpiece, the first direction parallel to the longitudinal axis of the workpiece, a sensor coupled to the magnetic abrasive brush that may be configured to measure a working gap between the magnetic abrasive brush and an outer surface of the workpiece at any given instant. The working gap may be a distance between a center of the magnetic field and the outer surface of the workpiece along a first axis perpendicular to the longitudinal axis of the workpiece. The system may further include a control unit that may be coupled to the magnetic abrasive brush and may be configured to adjust a magnetic flux density of the magnetic field based on the measured working gap at any given instant.

A container for the cleaning of an object, intended to receive, in addition to the object to be cleaned, a fluid including ferromagnetic components, and intended to be submitted to the action of a magnetic field generated by the rotation of magnets. The container comprises a bottom wall, a lateral wall, and a removable closing lid, said container being transparent to the magnetic field. The lateral wall of said container comprises on its inside radially-protruding longitudinal fins.

A cylinder sleeve for an internal combustion engine may include a bore-through cylindrical body having an inner sliding surface. The inner surface may have a surface finish with a rugosity defined by a valley-and-peak structure. The rugosity of the inner surface may have a ratio between a peak density and a mean radius of curvature of peaks that is higher than 150 and lower than 400. The rugosity may also have a ratio between the mean radius of curvature of peaks and an average height of peaks that is lower than 1500.

A three dimensional (3D) definition of a build piece, from which a build plan has been derived, is received. The computer system generates, based on the 3D definition, a processing plan that includes a plurality of robotic instructions to successively orient a build piece created by an additive manufacturing process into successive orientations. The computer system outputs the processing plan for use by a robotic controller.
