Abstract: A method for applying a measurement scale to a guide rail surface of a linear profile rail guide, the guide rail having a first side surface and the measurement scale including at least one track extending linearly and longitudinally toward the guide rail, including several mirror regions arranged alternately one behind the other, and marking regions, uses a pulsed laser to generate a laser beam and introduces a microstructure in a first region corresponding to the at least one marking region of the first side surface. The laser generates the laser beam with a sequence of several light pulses that is directed at the first region so that the laser beam is moved two-dimensionally relative to the first region to irradiate different subregions of the first region one after the other by the light pulses. Each different irradiated subregion has an overlap with at least one other irradiated subregion.

Abstract: In the case of the grinding wheel (1) for grinding cutting tools and in the case of a tool grinding machine using such grinding wheels, the circumference of the grinding wheel (1) is formed as a peripheral ridge (5) with roof sides (3a, 3b) converging toward it, each having an abrasive coat (7a, 7b) (=double-cone wheel). Concave radii of a surface contour region (14) of the cutting tool can be ground with the ridge (5) and/or in each case one of the roof sides (3a, 3b) and all the convex contour regions can be ground with in each case one of the two roof sides (3a, 3b). Dressing of such a grinding wheel (1) is possible on the same machine tool that is used for grinding the tool. A grinding machine with such a double-cone wheel provides good workpiece accessibility, no problems with clamping means and machine paths that are small. The fitting of the machine with a number of wheels (for example coarse-grained for roughing and fine-grained for smoothing) is possible without any collisions occurring.

As a further feature, it is proposed to weld, adhere, etc., a further spacing plate (60) between the carriages (30, 32).
