A method for enabling a computer to select a burnishing tool model using information about customer requests input into the computer. The method for selecting a burnishing tool model include receiving a machining shape, a material, and a finished product dimension, selecting a display tool type using a display tool type selection unit, outputting the display tool type using an output unit, receiving a specified type through an input unit, outputting a branch condition using the output unit, receiving a specified condition through the input unit, selecting a selective tool model using a tool model selection unit, and outputting the selective tool model using the output unit.

A vacuum hole for suction holding a processing target object through vacuum is formed on a stage surface of a vacuum suction holding stage, and a hole corresponding to the vacuum hole is formed on an elastic pad. A jig includes a first projecting portion configured to be insertable into the vacuum hole on the vacuum suction holding stage, a support portion configured to come into contact with the stage surface with the first projecting portion inserted in the vacuum hole, and a second projecting portion projecting toward an opposite side to the first projecting portion with respect to the support portion and configured to be insertable into the hole on the elastic pad.

The present application provides a tool for cleaning a groove of a turbine rotor disk. The tool may include a pair of guides spaced apart from one another in a direction of a longitudinal axis of the tool, and a number of cleaning sheets positioned between the guides in the direction of the longitudinal axis of the tool. At least a portion of each guide may have a cross-sectional profile corresponding to a cross-sectional profile of the groove, and at least a portion of each cleaning sheet may have a cross-sectional profile corresponding to the cross-sectional profile of the groove. The present application further provides a method for cleaning a groove of a turbine rotor disk, and a tool system for cleaning a groove of a turbine rotor disk.

A boron nitride plate surface treatment method according to an embodiment includes a first polishing process and a second polishing process. In the first polishing process, a surface of a boron nitride plate is polished by using a first polishing member having a grit within a range of not less than F120 and not more than F220 or within a range of not less than #240 and not more than #320. In the second polishing process, the surface of the boron nitride plate is polished by using a second polishing member having a grit within a range of not less than #360 and not more than #1000. The second polishing process is performed after the first polishing process. The boron nitride plate is suitable for a method for producing a silicon nitride substrate.

A microfiber yarn is provided for cleaning, polishing, and buffing a target surface. A buffing pad for auto detailing is provided that may be attached to a rotary drive tool that has a microfiber buffing surface, where the microfiber is a yarn, as opposed to a weave. Embodiments of the buffing pad operate to clean and polish a substrate such as a vehicle and ideally return the same to the original look and feel in a fast and efficient manner, while providing high quality finishes with less frequent pad changes.
