Document Type and Number:
WIPO Patent Application WO/2016/021620
Kind Code:
A1
Abstract:
Provided is an end-face machining device for polishing the end surface of a plate-like object such as plate glass by using the outer-circumferential surface of an attachable/detachable rotary grindstone, the end-face machining device being one requiring no time for a rotary grindstone exchange operation, and exhibiting no decline in production efficiency. An end-face machining device (1) for machining the end surface of plate glass W by using the outer-circumferential surface of a rotary grindstone (20) capable of being attached to a rotating means (21) and detached therefrom, wherein an annular groove (20c) is formed in the circumferential direction in the outer-circumferential surface of the rotary grindstone (20) after attaching the rotary grindstone (20) while the groove (20c) is not yet formed to the rotating means (21).
