A magnetic-field-guidance system and methods of finishing a workpiece using a magnetic-field-guidance system are provided. The magnetic-field-guidance system comprises a workpiece holder, one or more tooling magnets each comprising a finishing tip, and one or more flexible bags containing magnetic media. The workpiece holder is configured to (a) be secured to a base and (b) secure a workpiece relative to the base. The flexible bag(s) are configured to be disposed on the opposite side and/or same side of the workpiece relative to the one or more tooling magnets. In collaboration with the tooling magnets, the magnetic media contained with the flexible bag(s) direct a magnetic field which thereby guides a magnetic-abrasive slurry to finish the workpiece using Magnetic Abrasive Finishing (MAF).

Apparatus and systems are disclosed of a splash guard for a grinder/polisher having a base, a bowl, and a platen having an outer edge to prevent splashing during the grinding/polishing operation. The splash guard includes an inner sidewall, a lower rib, and outer sidewall, and an upper rib. The lower rib has an inner edge that is spaced at least 2.5 centimeters from the outer edge of the platen to prevent pinching of an operator's hands between the platen and the splash guard. The splash guard may also include a recess formed by the upper rib, outer sidewall, and lower rib, and at least a portion of an inner edge of the upper rib is extending further inwardly towards that platen than the inner edge of the lower rib.

A method of treating bearing rolling elements or bearing rings after a hardening and temper heat treatment is disclosed. The method may include treating the bearing rolling elements in a tumbling treatment and then in a duplex hardening treatment. The method may include treating the bearing rings in a peening treatment and then in a duplex hardening treatment. The duplex hardening treatment may also include at least one sequential process segment consisting of subjecting the bearing rolling element & rings to a nitriding process to increase the surface hardness and compressive residual stress. The combined two-step process produces a deep surface/sub-surface residual stress greater than the depth of the maximum operating von-Mises shear stress along with an ultra-hard surface with high magnitude of compressive residual stress. In so doing, the bearing ring and rolling elements will have significantly enhanced rolling contact fatigue resistance and resistance to surface imperfections and debris.

The present invention provides a resurfacing ball container for repeated removal of dirty, used or damaged surfaces from a plurality of India rubber type bounce balls. The resurfacing ball container also allows for easy transport and storage of balls during periods of non-use. The resurfacing ball container includes a cylinder with a lid and an abrasive surface rotating within the cylinder for resurfacing the contained balls.

A component production method includes: a step of binding a long frame by a plurality of support devices arranged along the frame; a step of measuring, with a distance sensor, a distance to the frame supported by the plurality of support devices; a step in which, based on frame shape data prerecorded in a memory, the support devices move support positions where the frame is supported so that a calculated radial position of the frame being supported by the support devices matches the data about the frame shape; a step of fixing the frame in a state in which the data about the frame shape matches the radial position of the frame; and a step of performing a hole-making operation on the fixed frame.
