To simplify and to shorten the cutting of a glass sheet (3) with the help of a cutting tool (11) and the removal of a coating applied on glass sheet (3) with the help of a grinding tool (12), the scratching of glass sheet (3) and the removal of the coating in strips lying on both sides of the scratch lines, running parallel to the latter, is performed in a single operation. In the device proposed for this purpose, cutting tool (11) and grinding tool (12) are mounted on a common support (8) movable on a beam (5) over a supporting surface (2) for glass sheet (3). Grinding tool (11) is fastened to an auxiliary support (17), which can be pivoted around axis (10) of cutting tool (11) oriented perpendicular to supporting surface (2). Grinding tool (12) and cutting tool (11) can be raised from glass sheet (3) independently of one another and mounted on the latter. Further, a suctioning of the dust accumulating during removal of the coating from glass sheet (3) is provided.
In a device for cutting a glass sheet (3) with a cutting tool (11), which can be rotated around an axis perpendicular to a supporting surface (2) for glass sheet (3) to be machined, and for removing a coating, applied on the glass sheet, with a grinding tool (12), which removes the coating from glass sheet (3) in strips lying on both sides of scratch lines (22, 26), running parallel to the grinding tool, with a beam (5), which is guided movably over said supporting surface (2) on its edges, and with a cutting tool (11) as well as a grinding tool (12), which are guided movably on beam (5) along the same;
