Embodiment Construction

[0044] Figures 1 to 4 The embodiment of the device 1 configured in the manner of a grinding wheel shown in includes a carriage 12 serving as a (drive) shaft and an annular grinding wheel 25 with two annular grinding wheel parts 6 . The annular grinding wheel part 6 is arranged displaceably on a carriage 12 configured as a shaft in the direction of the axis 2 of the carriage 12, such as image 3 and 4 Shown by arrow 13 in.

[0045] A line 14 for supplying liquid (supply water) is arranged in the carrier 12 such that the ring wheel part 6 of the ring wheel 25 is supported (floating) on ​​the carrier 12 via a hydrostatic bearing. Instead of a hydrostatic bearing for the annular grinding wheel 25 or the annular grinding wheel part 6, a gas (air) bearing can also be provided. In the case of a gas bearing, gas (eg air) is supplied via line 14 .

[0046] The supplied liquid (water) can also flow out through the gap 15 between the annular grinding wheel parts 6 in the direction to...

Abstract

In a device (1) for trimming panel-type workpieces (8), such as glass panes, a grinding ring (25) is used which is caused to rotate about an axis (2) by a drive. The grinding surfaces (7), engaging in a material-removing manner on the edges (9) of the border (10) of the workpiece (8), are designed such that they move in the axial direction, so that they can follow the edges (9) of the workpiece (8) during trimming. The grinding surfaces (7) automatically rest on the edges (9) of the workpiece (8) to be trimmed, even when the edges (9) are not in the predefined target position. The grinding ring (25) is floatingly mounted on its carrier (12) via a hydrostatic bearing or a gas bearing.

Description

technical field [0001] The invention relates to a device for processing the edges of flat workpieces, such as glass panes, having the features of the preamble of claim 1 . [0002] The device according to the invention comprises a grinding surface for abrasively processing an edge on an edge of a flat workpiece, for example a glass pane, which abrasively acts on the edge of the flat workpiece edge. The device according to the invention can also be designed and arranged for polishing the edges of workpieces. Background technique [0003] Devices for processing the edges of flat workpieces, in particular glass panes, are known in various embodiments. There are devices with grooved grinding wheels, for which see WO 2015 / 055671 A1, EP 1607177 B1 and EP 1488886 B1. [0004] Belt sanders are also known for abrasively processing flat workpieces, in particular glass panes, in order to correct their edges, as are known, for example, from EP 1344604 B1 or DE 4419963 C1. [0005] It...
