  • Patent number: 9987696
    Abstract: An automated bore finishing process particularly adapted for lapping automatically corrects one or more bore parameters, such as diameter, geometry, surface finish, in an iterative manner to reach a final value, controlled by algorithms that process feedback from a measurement process. The process determines bore parameter information and determines an optimum set of values for the process parameters, such as stroke position, stroke length and duration of the next lapping iteration. This optimization is targeted to achieve the desired final bore parameter or parameters within the specified bore size limits, and may be used to alter the stroke profile either for the entire next iteration or in a continuously changing manner, to minimize or eliminate bore defects over one or a succession of iterations.

  • Patent number: 9238308
    Abstract: A cutting method of a honeycomb formed body is provided. This is a cutting method of a honeycomb formed body in which, while a kneaded material containing a ceramic raw material is extruded to form a honeycomb formed body with a honeycomb shape having partition walls defining and forming a plurality of cells, the extruded honeycomb formed body is cut before drying by a cutting blade vibrated at a frequency of 0.3 kHz or more in a direction perpendicular to a direction in which this honeycomb formed body moves. It is preferably a cutting method of a honeycomb formed body in which the cutting blade is vibrated at a high frequency of 10 kHz or more.

  • Patent number: 9126302
    Abstract: A device for sharpening one or more cutting edges of a dental curette has a base support with a frame articulated thereon, and at least one sharpening guide. The frame supports a grinding wheel rotationally driven by a motor and a sharpening guide support intended to receive the sharpening guide(s). The guide includes at least one indicator in the form of a line marked on the guide, whose angle with the horizontal being between 10° and 50° but preferably equal to 10°, 20° or 30° and corresponding to the type of dental curette to be sharpened. The sharpening guide(s) can move with respect to the support, and the support and/or the guide include(s) indexing and positioning elements determining indexing positions of the guide on the support, each indexing position corresponding to a different indicator. A method of sharpening one or more cutting edges, and a sharpening guide are described.

  • Publication number: 20110287695
    Abstract: A radially inwardly open raceway formed in a nut centered on a nut axis is machined by of oscillating the nut about the nut axis while pressing a tool secured in a holder radially outwardly into the raceway of the nut. The holder is moved parallel to the nut axis and oscillated about a tool axis perpendicular to the nut axis synchronously with the oscillation of the nut about the nut axis. Springs brace the tool against the holder parallel to the nut axis such that the tool can move limitedly in the holder against spring bias parallel to the tool axis.

  • Patent number: 6149512
    Abstract: A linear pad conditioning mechanism provides a linear in situ or ex situ conditioning for a polishing pad mounted on a polishing belt of a CMP apparatus. The linear pad conditioning mechanism includes a linear oscillation mechanism for driving a conditioning pad in a direction orthogonal to the polishing belt's direction of travel. In one example, multiple conditioning assemblies are provided to each provide a trapezoidal conditioning pad, and the conditioning assemblies are positioned such that a constant-width area in the polishing belt's direction of travel is provided. In that example, a rotational mechanism is provided to position the conditioning pad between a conditioning position against the polishing pad, and a cleaning position in a bath of cleaning fluid. Further, each conditioning assembly is provided a fluid delivery system to a conditioner block, so that a conditioner fluid can be delivered at the point of use.
