The invention relates to a method and a device that are used for implementing a laser processing method for generating recession in an area of contact surfaces of relatively moving machine components. The recession used as a microstructure then serves as an adhesion base for optimizing a coating. To enable a laser beam emitted from a laser processing head of a device (9) to move at a desired high feeding speed larger than 5 m/s, a reflector component (10) is enabling the laser beam (4) to deflect is arranged in a protective tube (11), and the laser processing head and an unexpressed work piece clamping head applied to machine components can be designed to be static in processing time. Under the condition, the reflector component (10) and the protective tube (11) can together be driven in such a way that the he reflector component (10) and the protective tube (11) rotate around a rotating axis line (12) which is coaxial with the laser beam (4).
