Experimental study about micro texture on ceramic tool surface processed by UV laser

Tool surface with micro texture has good effect of anti-friction, increases adhesion resistance and abrasion resistance of the tool, and prolongs its life. Laser processing technology had obvious advantages in the preparation of micro texture on tool surface. The ideal surface micro texture of a tool can be obtained by laser processing technology under the reasonable processing conditions. In order to find the effects of laser energy density, frequency, laser beam scanning speed and scanning times on the dimension of tool surface micro groove, experiments were carried out under the condition of single factor of UV laser. The experiment at the preparation of micro texture on ceramic tool surface with 355nm wavelength UV laser was carried out. The reasonable condition parameters were determined. The study has guiding significance for working out suitable micro textures and improving the performance of ceramic tools.
