The conical internal teeth (7) of a spur gear grinding tool (2) mesh with the teeth (6) of a spur gear workpiece (1) or a dressing spur gear. The tool axis (4) forms an acute angle ( gamma ) with the workpiece axis (3). To grind and to dress, the spur gear tool (2) is fed relative to the workpiece (1) in the direction of the tool axis (4). In this manner an optimal tooth meshing between the tool (2) and the workpiece (1) over a wide dressing range and a constant finishing are achieved.
