Embodiment

[0083] Hereinafter, examples of the vibratory barreling method of the present invention will be described. In addition, this invention is not limited to these Examples.

[0084] In this embodiment, as the jig 1 for grinding, a simple shape and figure 1 Same fixture. The outer diameter of the first guard member 10 and the second guard member 11 is 840 mm, and the width of the polishing jig 1 is 213 mm (1 / 4 or more of the outer diameter). The shielding member 13 has a width of 50 mm, which is 5 / 4 times the width of the workpiece W described later. The length of the window portion 11w is 210 mm in the center direction and 480 mm in the circumferential direction.

[0085] The workpiece W of this example is a titanium disk with a diameter of 800 mm and a thickness of 40 mm. As the grinding medium M, a triangular prism chamfered sintered medium (manufactured by Shinto Kogyo Co., Ltd.) with a side of 4 mm and a length of 4 mm was selected, and filled into 1 / 3 of the volume of the...

Abstract

One embodiment of the present invention provides a vibrating barrel polishing method that uses a vibrating barrel polishing system which comprises a polishing tank that has a bottom surface therein, and a polishing jig that can hold a workpiece and can rotate around a rotational axis. The method includes: a step for supporting the polishing jig inside of the polishing tank in such a manner that the bottommost part of the polishing jig is separated from the bottom surface, the separation distance d between the bottommost part of the polishing jig and the bottom surface being equal to or greaterthan the particle size of a polishing media; a step for causing the polishing media to flow inside of the polishing tank; and a step for rotating the polishing jig around the rotational axis in sucha manner that the bottommost part of the polishing jig is separated from the bottom surface.

Description

technical field [0001] The invention relates to a vibration rolling method and a vibration rolling system. Background technique [0002] Vibration barreling apparatuses are known for polishing the surface of a workpiece as an object to be polished to a predetermined surface roughness, or for removing burrs, oxide films, and the like. [0003] For example, a vibrating barreling device described in Japanese Patent Document 1 includes a grinding tank and a driving unit that vibrates the grinding tank. When using the vibrating tumbling device to grind a workpiece, the workpiece and the grinding medium are put into a grinding tank, and the grinding tank is vibrated along an approximately arc-shaped orbit. Thus, the object to be ground and the grinding medium move relatively to grind the workpiece. In addition, in this vibratory barreling device, a plurality of workpieces having a flat shape such as a disc shape are ground at predetermined intervals in a direction perpendicular ...
