摘要： 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.

摘要： A radial grinding tool for a machining center utilizing through-spindle coolant is disclosed and includes a main body having a central longitudinal axis, a spindle extending along the central longitudinal axis, a disc-shaped wheel member located at an end of the spindle and including a working surface at a periphery of the wheel member, and a passageway extending through the main body configured to accommodate a flow of coolant. The tool includes an impeller attached at a lower side of the wheel member and having a plurality of blades that are configured to impart a force against the coolant to reshape the flow of coolant into a generally flat stream and redirect and drive the coolant radially outward from the central longitudinal axis to the working surface.

摘要： An orderly-micro-grooved PCD grinding wheel includes a wheel hub, a polycrystalline diamond (PCD) film, a number of micro-grinding units and a number of microgrooves. The PCD film is deposited on an outer circumferential surface of the wheel hub. The PCD film is processed by a water-jet guided laser device to form the microgrooves with high depth-width ratio and micro-grinding units with positive rake angles on the entire outer circumferential surface of the PCD film. An axial length of each micro-grinding unit and an axial length of each microgroove are equal to a thickness of the grinding wheel, respectively. The microgrooves are spaced apart by the micro-grinding units.

摘要： A forming tool for forming leading edges of turbine blades is disclosed. In various embodiments, a forming tool may comprise a cylindrically-shaped body having a notch around the circumference of the cylindrically-shaped body. The notch may be positioned perpendicularly to a center axis of the cylindrically-shaped body. Further, the notch may have a notch contour with an upper notch contour and a lower notch contour, and where the notch contour is a relief of a selected turbine blade leading edge. The forming tool may be a grinding tool or a cutting tool. Moreover, a forming process may comprise forming, by a forming tool, a first portion of a turbine blade leading edge with a rough edge result, and forming, by a milling cutter, a second portion of the turbine blade leading edge with a rough edge result.

摘要： An abrasive tool can include a bonded abrasive including a body and a barrier layer bonded to a major surface of the body. The body can include abrasive particles contained within a bond material. The barrier material can include a metal-containing film. In an embodiment, the barrier layer may further include a polymer-containing film. In another embodiment, the barrier layer may include a biaxially oriented material. The abrasive tool may be formed such that the barrier layer is formed in-situ with the formation of the bonded abrasive.
