Abstract: A method for producing a sheet metal product (1) from a sheet metal preliminary product (2) is proposed, wherein at least one surface (7) of the sheet metal preliminary product (2) is coated with a coating, wherein the sheet metal preliminary product (2) is rolled, wherein depressions (6) are rolled into the surface (7) during the rolling operation, wherein after the coating and rolling operations lubricant (8.1) is introduced into the depressions (6), wherein after the introduction of lubricant (8.1) the sheet metal preliminary product (2) is mechanically formed by a forming tool (5), characterized in that the surface (7) is coated in such a way that, in the forming tool (5) during the forming process, in particular under relative movement between sheet metal surface and tool surface, the coating is elastically deformable under loads of 0.5 MPa to 20 MPa and plastically deformable under loads of above 20 MPa.

Abstract: An apparatus for structuring a roller surface is proposed, wherein the apparatus has a laser source and an optical system, wherein the laser source is designed for generating laser pulses, wherein the optical system has at least one beam shaper, at least one beam splitter, and a focusing unit, wherein the combination of beam shaper and beam splitter is arranged between the laser source and the focusing unit.
