A shot blasting wheel for use with a shot blasting machine configured to propel abrasive shot against a workpiece. The shot blasting wheel includes a circular body member defining a plurality of slot openings a front surface defines a plurality of slots. Each slot and slot opening has a dovetail configuration. The shot blasting wheel includes a plurality of blade assemblies, each including a paddle positioned in a respective slot via insertion through a respective slot opening. Each blade assembly also includes a locking lever pivotally coupled to the body member and pivotally movable between a locked configuration preventing removal of the paddle from the respective slot and a released configuration allowing removal. Further, each blade assembly includes a dual spring assembly having a lever spring tensioned and biased for movement between extended and released configurations and having a paddle spring configured to resist a paddle lug.

A grinding apparatus includes: a grinding stone in which an outer circumferential surface thereof is pressed against the workpiece while being rotated and driven; and a fluid injection apparatus that has a fluid injection nozzle including an injection port from which a fluid is injected to the outer circumferential surface of the grinding stone, and a grinding oil supply apparatus that supplies a grinding oil to a processing point and that includes a grinding oil supply nozzle separate from the fluid injection nozzle, the processing point being an abutting section of the grinding stone and the workpiece, wherein the injection port is arranged so as to face the outer circumferential surface of the grinding stone in a state capable of injecting the fluid to a position different from the processing point in a radial direction of the grinding stone among the outer circumferential surface of the grinding stone.

A method includes positioning a cylindrical tool having one or more rows of blades within a cylindrical bore having a surface, forming annular grooves and peaks into the surface with the grooving blades when the swaging blades are in the retracted position, and translating the swaging blades from the retracted position to the extended position to deform the peaks. The one or more rows of blades includes fixed grooving blades and translatable swaging blades having retracted and extended positions.

A center shaft machining apparatus includes: a grinding structure that moves on a machining central axis while rotating about the machining central axis and machines an end surface on one end side of a workpiece arranged on the machining central axis; an end portion support structure that supports an opposite end side of the workpiece; and a shaft portion support structure that supports a shaft support portion set at an intermediate portion of the workpiece. The end portion support structure includes an eccentric mechanism capable of supporting an opposite end of the workpiece in a state where a workpiece central axis of the workpiece is eccentric with respect to the machining central axis.

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.
