Abstract: As a new processing method, laser micro texturing has a broad application prospect in the field of friction pair surface treatment. Through non-contact machining, the micro morphology of the workpiece surface is textured to meet the tribological characteristics, so as to improve the service life of the workpiece without changing the mechanical properties of the workpiece. By using four axis motion control card and general windows numerical control software, a special laser micro texture device for workpiece surface is developed. The mechanical structure, control system hardware and software of the laser micro texturing equipment are introduced. The construction process, working mechanism and key technology of the whole system are described. At present, the device has been put into work piece test, and micro texture machining has been successfully carried out on flat plate and mechanical seal surface.
