Title:
END FACE PROCESSING DEVICE
Document Type and Number:
Japanese Patent JP2021169140
Kind Code:
A
Abstract:
To provide an end face processing device in which burdens of securing tensile strength of polishing tools such as a linear brush can be reduced and polishing tools made of a wide range of materials or with a wide range of structures can be used.SOLUTION: An end face processing device 100 comprises: a work-piece holding tool 110 that attachably and detachably holds a work-piece 90 made of a glass substrate; a second polishing tool 130 for performing polishing processing to a recessed part 92 of the work-piece 90; and a back face receiving tool 140 that regulates displacement of the second polishing tool 130. The second polishing tool 130 is configured so that a polishing part 130b made of brushes made of resin is provided around a metallic line-like core body 130a. In the back face receiving tool 140, a receiving part 142 is formed in a block-like receiving tool main body 141. In the receiving part 142, a cross section on which the polishing part 130b can be stored is composed of a curve surface in a circular arc shape. The back face receiving tool 140 is positioned so that the receiving part 142 is positioned on an extension line in a circular arc with a curvature at which the recessed part 92 is configured.SELECTED DRAWING: Figure 1
