Abstract: The ideal surface micro texture can reduce tool surface friction coefficient and improve the friction,wear performance of tools and cutting performance.The effects of laser power,frequency,laser beam scanning speed and scanning times on the dimension of tool surface micro groove and the morphology were studied by measuring and ob-serving the surface micro textures during laser processing of surface micro texture on ceramic tool.The reasonable pa-rameters of 1 064 nm wavelength fiber laser were determined.Different morphologies of micro texture and no texture on the ceramic tool were compared through the friction and wear experiments.The experimental results show that the mi-cro texture on the surface of ceramic tools can reduce the friction coefficient and improve its anti-wear properties.When the depth and width of the micro grooves are too big,the effect of micro texture becomes poorer.
