There is provided a method for processing a raceway groove configured to circumferentially form a to-be-processed side raceway groove on a surface to be processed of a workpiece, the to-be-processed side raceway groove is configured to be brought into rolling contact with a rolling element, and the surface to be processed is a cylindrical circumferential surface. The method for processing a raceway groove includes: arranging a processing rolling element rotatably between the to-be-processed side raceway groove and a tool side circumferential surface which is opposed to the surface to be processed and which is a cylindrical circumferential surface of a machining tool; rotating the machining tool relatively with respect to the workpiece; and performing a burnishing process on the to-be-processed side raceway groove.

A tire pre-conditioning system includes a first mandrel, a second mandrel spaced apart from the first mandrel, and a controller in communication with the first mandrel and the second mandrel. The first mandrel is fixedly attached to a first shaft and including a first tapered sidewall. The second mandrel is fixedly attached to a second shaft and including a second tapered sidewall. The controller is operable to axially move the first mandrel and the second mandrel toward one another until the first and second tapered sidewalls are opposing respective beads of a tire, and supply pressurized fluid into an internal cavity of the tire to inflate the tire. The inflating causing the beads to move relative to the mandrels while contacting the opposing respective tapered sidewalls to burnish the beads of the tire.

A burnishing tool and a method of additively manufacturing components of the burnishing tool are provided. The burnishing tool includes a burnishing element for burnishing a workpiece. The burnishing element is positioned between an upper nozzle and a lower nozzle which are additively manufactured to define a plurality of internal fluid passageways for receiving, distributing, and discharging a burnishing fluid to facilitate cooling and/or lubrication of the burnishing element and/or the workpiece.

The Present Invention introduces novel methods and tools for improving the surfaces of metals and other flowable materials with smooth-surfaced tools, such as fibers and spheroids bonded to a ground. The new tools deform and compress rather than remove material, thereby increasing surface hardness, density, reflectivity, electrical conductivity, impermeability and corrosion resistance. Benefits include economies in production and maintenance, an improved work environment, and reduced costs for energy, stock materials and precious metal reclamation.

A technique facilitates formation of a burnished region, e.g. a seal region, via plastic deformation of an internal surface. The technique utilizes a burnishing assembly which may comprise a stem sized for insertion into a tubular region. The stem may be combined with an actuator and a plurality of rolling elements mounted on the actuator. When the actuator is actuated to a radially outward position, the plurality of rolling elements may be moved into engagement with the internal surface until plastic deformation occurs. The stem may then the rotated to force the plurality of rolling elements along the internal surface so as to form a region of plastic deformation. The plastic deformation may be located to form a seal, for example, between adjacent components.

Various kinds of finishing and hardening treatments of holes by methods of plastic surface deformation can find application in many branches of engineering industry. In particular for burnishing holes on a milling or drilling machine tool. A device for diamond-burnishing of holes increases the functional possibilities, improves the quality of the treated hole surface and the endurance of the burnishing tool, provides the opportunity for a precise regulation in order to get the necessary hole caliber, and uses the load of all the weights for obtaining the necessary pressing force. The device structure comprises a housing with a tapered stem, central and terminal arms with crossheads and shafts, bars with weights, a foot with a cylindrical body, and an arbor with a diamond-burnishing tool.

Processing tool for processing a surface of a workpiece. The processing tool includes a tool body which defines a tool axis. At least one first roll element, which is borne by the tool body, is rotatable around a first roll element axis and has a first outer surface with a rough surface structure in at least one first working section configured for rolling contact with the workpiece surface. Further, at least one second roll element, which is borne by the tool body, is rotatable about a second roll element axis and has a second outer surface that, in at least one second working section configured for a rolling contact with the workpiece surface, has a distance (r2) to the tool axis, which is less than a distance (r1) of the at least one first working section to the tool axis.
