厚みを2.5mmとする。(Example) In the drawing, reference numeral (1) indicates a stone stone having a V-shaped polishing groove (2) on the periphery. The glass sheet (3) or (4) is carried on a fixed support table (5) which is fixed vertically, ie without moving up and down. By displacing the stone (1) in the vertical direction, the symmetry plane of the polishing groove (2) coincides with the center line of the edge of the glass sheet (3) or (4). Continue to move the stone light (1) in the horizontal direction.
Alternatively, the edge of (4) is engaged with the side surface of the polishing groove (2).
In this state, polishing is performed by rotating the stone (1) about a vertical axis. The support table (5) may be moved in the horizontal direction instead of the stone (1) and further rotated. As the stone (1) rotates, the sharp edges of the glass sheets (3) or (4) are symmetrically polished. in this case,
For example, the thickness of the glass sheet (4) is 2 mm, and the thickness of the glass sheet (3) is 2.5 mm.

二分の一、即ち本実施例の場合0.25mmである。Depending on the thickness of the glass sheet, the stone (1) moves up and down in the vertical direction, that is, in a direction perpendicular to the plane of the glass sheet. That is, depending on whether the sheet glass is thick or thin, the stone (1) rises to the operation position (II) or descends to another operation position (I). In the left part of FIG. 1, a thick plate glass (4) is carried on a support table (5), which is arranged at the same level as the right table (5). With one common fixed table (5), 2.0mm and 2.5mm thick sheet glass can be polished alternately and automatically at the respective working positions (I) and (II). It can also be configured. Then, at each of the operating positions (I) and (II), the stone (1) is arranged at a predetermined level, and the polishing groove (2) is formed in the plate glass (3) or (4).
Is polished. The vertical deviation of the stone (1) at this time is one half of the difference between the thicknesses of the two different thicknesses of sheet glass, that is, 0.25 mm in the present embodiment.
