The invention relates to a method for making recesses in the surface of a rolling roller for a rolling press. The invention provides for a thermal treatment of a cylindrical roller surface, wherein the roller surface is heated in the region of the desired recesses until the material properties of the roller surface change permanently, i.e. even after cooling, with respect to the hardness of the roller material. By virtue of a first start-up, the desired profiling is formed spontaneously by the desired recesses. The thermal treatment represents a particularly simple and cost-effective method for profiling rolling rollers, and in particular rolling rollers which have already become worn can thereby be readily refurbished. |
