Abstract: 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 mandrels while contacting the opposing respective tapered sidewalls to burnish the beads of the tire.

Abstract: A combination cutting and burnishing orbital drilling tool may include an elongate tool body including a cutting end and extending along a longitudinal axis. The tool body may include a burnishing portion spaced from the cutting end and configured to induce residual stress in a side wall of a hole without removing material. The tool body may further include a cutting portion interposed between the cutting end and the burnishing portion. The cutting portion may be configured to remove material from a workpiece, thereby creating the hole, during an orbital drilling process.

Abstract: 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.

Abstract: 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.

Abstract: Disclosed is a rolling tool which serves for working—in particular rolling smooth—an inner lateral surface of a cylindrical clearance. For this purpose, the rolling tool has at least one rolling body, which is held in the rotatably drivable rolling tool, and can be taken along by said tool on a peripheral path along the inner lateral surface. The at least one rolling body is inserted into a radial clearance in the rolling tool and can be subjected to a pressurized fluid from the inside to the outside along the radial clearance. The fluid is an aerosol. The aerosol is a fluid mixed with gas and serves for hydrostatic bearing and lubrication.

Abstract: In a method of machining a surface of a bore of an aluminum cylinder block for internal combustion engines, the bore surface is machined to be formed with a number of recesses which are to be formed into oil reservoirs. The bore surface is then pressed uniformly to be plastically deformed so that each recess is narrow at its opening and broad in its inner part. The machining for formation of the recesses and the working for plastic deformation for narrowing the opening are combined together so that the bore surface is machined to have oil reservoir recesses each of which is narrow at its opening and broad at its inner part.
