  • Centerless grinding machine
    Patent number: 10166645
    Abstract: A space-saving centerless grinding machine having high operability is obtained by devising the configuration of component units around the basic configuration of the machine. A dressing means for performing a dressing process for a grinding wheel and a regulating wheel comprises a single dressing unit. The dressing unit is located at a lower position between the grinding wheel and the regulating wheel, and thus eliminates the need for right and left dresser spaces for grinding wheels that have most seriously affected the breadthwise dimension of a conventional centerless grinding machine, leading to space saving and a considerable reduction in the breadthwise dimension of the centerless grinding machine.

  • Blade positioning
    Patent number: 10160086
    Abstract: A method of, and apparatus for, urging blades of a gas turbine engine radially outwardly is disclosed. The method may be used to grind blade tips of blades of a rotor stage of a gas turbine engine. The method comprises locating a fluid-tight bag which is in a radial gap formed between a radially inner surface of a respective blade root and a slot in a disc which the blade root cooperates. The method comprises inflating the fluid-tight bag and rotating the rotor stage relative to a grinding surface so as to grind any blade tips that contact the grinding surface during rotation. This results in more accurate positioning of the blades during the grinding process and/or during operation.

  • Dressing tool and method for the production thereof
    Patent number: 10160095
    Abstract: Dressing tool including a main body having a working surface covered with hard-material grains distributed on the main body. Recesses for accommodating the hard-material grains are created in the main body and then filled with an adhesive, the excess adhesive is removed across the main body, and thereafter the hard-material grains are flung onto the main body so that only the grains located in the recesses remain adherent to the working surface of the tool. The hard-material grains can then be bonded to the main body by a physical and/or chemical bond. Thus, a distribution of the grains over the working surface of the tool that can be precisely defined in advance is ensured.

  • Reduced noise abrasive blasting systems
    Patent number: 10150203
    Abstract: Reduced noise abrasive blasting assemblies and systems are described. The new assemblies and systems are comprised of standard blast hose, accelerator hose, couplings and nozzle. The improved abrasive blasting system maintains abrasive particle velocity while decreasing the exit gas velocity and consequently decreasing sound production. This is accomplished through an acceleration section with reduced inner diameter and sufficient length to provide the necessary abrasive particle velocity. The new system maintains the productivity and efficiency of conventional abrasive blasting systems but with greatly reduced acoustic noise production and reduces operator fatigue due to the lower weight of the carried portion of the system.

  • Lens-centering method for spherical center-type processing machine, lens-processing method, and spherical center-type processing machine
    Patent number: 10124459
    Abstract: According to this lens-centering method, a state in which a lens is sandwiched at prescribed pressing force between a lens holder and a lens processing dish is brought about. Next, the lens-processing dish is rotated at slow speed about a rotation axis line that passes through the center and the spherical center of the lens-processing surface thereof, and is made to oscillate at a slight angle about the spherical center of the lens-processing surface as the center of oscillating action. The spherical center of a first lens spherical surface of the lens is guided to the spherical center of a lens-retaining surface of the lens holder, and the spherical center of a second lens spherical surface is guided to the spherical center of the lens-processing surface.
